Amazing job man! This is such an underrated review. Reviewers never touch on sims, Tripple screens or VR and it leaves us sim guys who actually max this hardware out hanging.
Such good info here! Finally some hope for racing in VR at Daytona and Long Beach 😅
Agreed bugs me no one ever does benchmarking/testing of triples, and also only does F1 2022. I just assume 4K is a similar number of pixels to triple 1440P, of course there’s a lot
More to it than that, but there’s a niche in the market, big enough I’d have thought, for at least one dedicated Sim specific hardware/software review channel to do this sort of thing on the main sims, IRacing/ACC/AC/RF2/AMS2. Possibly flight sims as well MSFS2020/DCS etc.
Damn as I type that that feels like an awful lot of work!
This video was so well done! Absolutely great information. It's been hard finding a lot of people that test certain things for triple screen sim racing. Would love a video just like this one about graphics cards for triple screen sim racing. Vram, clock speed, cuda cores, dlss/fsr, eyefinity v surround, cards w/3 dp ports. It's been hell trying to choose a GPU for my new 7800x3d build (glad I got after watching this video!)
If you're running triple screens, I definitely recommend a card that has 3xDP or 3xHDMI. I'm not familiar with any technical limitations of 2xHDMI + 2xDP,, I have read mixed experiences from users.
iRacing is clever with managing VRMA limitations, and will automatically reduce image quality to fit textures within the cards capacity. I'm not yet sure how to tackle that challenge of 'image quality' assessment to these benchmarks given that situation, or comparing DLSS/FSR. Screen shot captures can tell a story that's very different from the motion on the screen. And if I try to capture that motion, TH-cam compression unfortunately muddles the finer details in video playback.
It's a challenging situation! But I'll do my best :)
This info is gold. Thanks for making this review with a very hard to find comparison
The most amazing and helpful video for simracers... Years waiting for it... Thank you so much...
Saving for my next build. Outstanding work my guy. Thank you!
Thanks for covering all the relevant resolutions. When I watch reviews of CPUs from big channels they just show 1080p low and I'm like "how is this relevant in 2024?". This helps much more, we need real world scenarios.
Fantastic video man. Well presented, well tested, well everything.
Hey mate, really appreciate the in depth analysis. You're a natural and looking forward to seeing more
Amazing analysis and very well presented. Thank you very much for the hard work and sharing it!
This was super super useful. Thanks a lot for doing this. This is exactly was i was hoping to find when searching for what fps gains i could expect by updrading my cpu for iRacing. Awesome stuff.
Btw congrats on the video! Was looking for this a few months back before upgrading, but still well put together! Subscribed brother 👍
Monster effort boss. Excellent work. Looking forward to more.
I’ve been looking for a video like this for years now, amazing job thank you!
Thank you! I've been waiting to... so I just decided to do it myself :) I'll be posting a lot more data and info, so stay tuned.
Much appreciated testing in a fairly niche field. Thanks mate, and subbed!
Thanks so much. When looking at buying a gaming PC for sim racing this is incredibly valuable information.
Very informative, keep these videos coming!
Wow, that was an awesome Video! Way to go, man! Your channel deserves to blow up! I was shocked that you „only“ have under 200 subs 😮 stay on it and you‘ll grow faster than you can look!!! 👍🏽
Man! This was awesome! More! We need more!
Thanks for the work you put in this!
Great video, thanks for putting this together! I have similar specs (14700K, 3080 12GB), and Santa is bringing me triple 1440p monitors. I am coming from the G9 and was a bit worried about a big dip in performance, but this video was reassuring!
What a great video! 👌🫡👊
Awesome video, very detailed and informative. I would love to see that AMD video.
Thanks so much for the video. Most comprehensive cpu comparison for sim racing.
Fantastic info and clear explanations...superb
Amazing video! thanks dude
Love the concept even more since I am considering getting 2 more monitors for my rig
Awesome work, this kind of information is so what I needed as I am planning my upgrade path. Greatly appreciate the video and many thanks.
Finally someone testing with triple screens!
Brilliant video. Thanks very much for such good analysis. My 7800x3d/4090 combo absolutely rocks iRacing and FS2020.
Very useful comparison. I would love to see the same for ACC 🙏
Great video, as an owner of a 9700k and a 3080ti this video was perfect. I'm planning getting iRacing this month and was a little concerned about my CPU.
Nice and informative Video. Thanks 👌
Thank you so much for this video! I was actually looking exactly for this kind of CPU comparison a month ago when I was deciding about my setup. I was fully aware that today 4070 TI probably would be more than enough for a triple 1440 setup but I opted for 4090 for future proof especially for the up coming AC2 and ACC2.
After watching many, many tests and reviews I opted for 7600X and I am happy with my choice since spending double on a CPU would really matter very, very little and proffered to invest into 4090 instead of 4080.
Again, great job!
Thank you :) And great CPU choice, the performance gap between 7600X and 7800X3D is fairly small considering the price jump. Now you're on the AM5 platform which AMD claims will even see new processors in 2025, so you can wait for a more enticing SKU.
4070ti will strugle .. vram issue :) my ultrawide 3440-1440p eating vrams from 16gb using 14gbvram...
from video I understood CPU is bottlenecked most time and GPU is sitting idling, not doing much. I thought it's important to get best strongest CPU for simracing. waiting fro AC EVO to be released and will see what PC I need. it will be same KUNOS engine as AC. Only ACC is Unreal engine.
Informative and concise. This helps, thank you.
Thank you for the research and testing.
insanely helpful video. curious to see how the AMD vs Nvidia comparison goes, especially when it comes to fps lows in VR. Great work!
I rarely comment on videos, but this has been outstanding!
Very good video in terms of production and also methods used to benchmark... this makes my life even harder, currently running 1440x7680 @ 144+ fps with 5600x and 3080ti... but i really wish i could up some eye candy (and less aggressive LOD settings) and still maintain the framerate. To just drop in a 5800x3d and spent money on a "dead" platform or wait for the next gen of am5 x3d..
Thank you :) Personally, I'd hold out for the next X3D! Yes an upgrade to faster AM4 processor can yield a measurable improvement in tough scenarios, a little more eye candy, but it may not deliver that 'wow' feeling that we all want from an upgrade.
This is awesome. I have been waiting years to see this exact same kind of testing. I'm running a 9900k with a 4090 on trip 1440p with a 4th 1440p on top atm and it still seems to be doing well enough with all my extra stuff too. I almost upgraded to the 13700k but built my wife a new pc instead. Hope to build my sim rig replacement later this year with the latest new Intel. It's not the 15th gen but whatever they're going to call it.
*great video! Thanks for all the effort! :)
Interesting video, hard to find many benchmarks when it comes to triple screens for the likes of sim racing, had already made my mind to go down the 7800x3d route but very informative, you have earned my sub :). What I have been debating over is graphics cards, specifically amd or nvidia, leaning towards nvidia just because I heard that AMD graphics cards dont perform quite as well when it comes to triple monitors otherwise I would have already bought the 7900xtx, would be curious to see if this was still the case, the only video on the topic I had found was that of dan suzukis but that video is a couple years old now i believe.
Great video
I'm running an overclocked 7700k with a 4070ti triple 1440 and I'm very excited to upgrade to the 7800x3d, especially now! The jump is going to be insane 😂
Awesome, thank you a lot for all this work. Would have been great to see a chart with a middle end graphic card, like a 3070 or a 6800XT.
This pretty much defeats the purpose of this review of CPU's.
well, i was more asking for review on graphics card with different CPU, to see where bottleneck appears in those scenario, than anything else.@@leonn1196
Great Vid!!!! This has really helped. Have a 8700k oc'd with 2080ti. Maybe I was too optimistic thinking about going triple 1440p with good fps.
Thank you! :) If you're comfortable with lowering some settings, I think it's definitely playable with your setup. Your CPU+GPU combo is well balanced, but I'd take on a new CPU first if you don't upgrade both at the same time.
Really great video! Very informative and well made video. What I gathered from this video is that an upgrade from triple 1080 to 1440 is possible for the current hardware. I have 5800x3d and 3080ti.
Yes. At simple tracks with few buildings (Lime Rock Park) you will technically become 'GPU Limited' as indicated by the GPU Busy graph for Red Bull Ring, however, your FPS should easily average over 120fps. In complex scenarios like Daytona, your 5800X3D continues to perform as a high-end CPU.
I run a 5800x3d and a 3060ti. Getting 110+fps on all tracks with medium-high graphics at 1440p on triples. Grandstands and crowd on, etc. only exception is some of the new tracks but even then, 80+ fps
Thx for this analysis, enjoyd the video ! +1 sub
Thank you!
Great benchmark. Also interested in the radeon cards and how they hold up against there nvidia counterparts. Keep these reviews coming.
In iRacing ? Worst, just google it. Even iRacing staff say so.
Great video! And very well produced. All info right were you need it.
I'm curious if the same can be said about the X3D parts with ETS2 or ATS and loads of traffic. It's silly, but it can demand a lot with cars around too. (Same for the unoptimized City Car Driving.)
I'm curious too! I have both of those trucking simulators and a couple pieces of recent DLC. I'm planning to benchmark those after ACC.
Awesome videos mate. It would be great if you made a video showing us how to benchmark our own PC's with iracing
Thanks :) It's easy to capture data. The challenge is to understand the parameters you've selected and consistently perform the benchmark run. iRacing is developing a big update to its GUI, and I'm hoping they implement a standardized benchmarking tool within it.
This is actually quite interesting. I'm running a 3080TI at home on a 9700k, and it while it does pretty well, I was definitely thinking I was going to need a new video card at triple 1440p with 165hz monitors, but it turns out I just need a much better CPU!
Great video as it is very hard to find benchmarking for triple screens based on sim racing. I’m in the middle of installing triple 4k screens. I plan on running them at 1440 until I upgrade my 3080ti.
Here’s what they promised me! Proud of you! 🎉
Thanks for testing and posting the results.
I was specifically looking to see if/when the x3d would be worth the money over just a modern midrange processor like the 7600x
You won't notice the extra FPS gained by the 3D V-Cache in most iRacing scenarios. It takes complex and demanding circuits, like Daytona, for a significant gap to build. Also, X3D chipsdon't like being limited by your GPU, and at higher resolutions like Triple 1440p and VR, it's easy to be constrained by a GPU bottleneck.
If you can find a good bundle deal on a 7600 or 7600X, I'd take that and wait to see what AMD does for it's next gen of X3D on AM5.
Very interesting details that we don't often see in larger benchmarking videos! I'd be curious to see how the 7800X3D fares with a 4090 to remove any GPU bottlenecking. I gather the X3D was a lot more impactful in ACC than iracing initially. I'd also be curious to see how they fare while streaming.
I used to have triple screen but now i have VR headset. I really need that depth perception to give me sense of speed and sense actual size of the driving road only VR can give me
Simlab vario vesa mounts for the monitors so long as they are free standing. They work off of gravity but they make aligning the monitors a breeze.
Yes, those look great! I'm using a 'local' alternative from Advanced Sim Racing (www.advancedsimracing.com/products/advanced-vesa), but somehow I've screwed it up (pun fun). I'm going to reassemble them anyways, because I want to extended the monitors farther from the posts.
Super Helpful thanks.
If you also factor in the cost of electricity, the 7800x3d really comes out incredibly well! Great video.
It would be interesting to see the 'at the wall' measurement to capture total PC power usage with each CPU. Even though racing simulators are demanding on the processor, that doesn't mean the overall CPU usage is high... it seems like it's 25% overall. So the power consumption analysis may be counter intuitive: the 'newest' CPUs may consume the least AND provide more FPS than the 'older' CPUs that are struggling.
@@BenchmarkOdysseysyup! my new Corsair HX1000i has a usb connection to my motherboard, with Corsair Link (and eg HwInfo to isolate CPU) you can see exactly what's going on - and I'm amazed at the low power usage of the 7800x3d (w 4090). Also have a 5800x3d here (son's, my old), same PSU, it's just as frugal! (with 3070). Performance wise the newer system is beastly, especially when you look at per watt.
ps. brilliant analysis@@BenchmarkOdysseys - this would have taken ages. I've thought of upgrading my QHD 32s to 4k monitors, mainly because of my work as a software engineer / tech guy, but I see that this really would require a 5090 at this point!
Loving my 5800x3d with the 7900xtx! For triple 1440p can’t get frames below 160 on max settings, it’s been a blast!
Awesome! Does your card have triple DP, or do you use both HDMI+DP for the monitors?
@@BenchmarkOdysseys I have one with 3 DP (Merc310). I use it with a 7900X. Was watchhing to see if I have the power to upgrade to triples, I reckon I might :)
@@BenchmarkOdysseys only 2 dp and 2 hdmi
I started with a AMD 3600x and a 2070 Super, now my rig is a 5800x3d and a 3090 (same b450 MOBO), only other upgrade over time was going to 32gigs of b-die Ram clocked at 3800hz with tight timings (cl14). I haven’t been on iRacing in about a year but last time I was on I could pretty much lock it at 144hz with triple 1440’s… not maxed out graphics settings but definitely not turned down to much either…
Funnily enough, my 5800 X3D came in today to replace my 3600. Just put it in 2 hours ago and I'm ecstatic that it's alive!
how is the framerate improvement? I have a rzen 5 3600 as well.
@@glenndjenkins Let me get back to you on concrete numbers. In FFXIV I was around 60 fps high settings in high workload situations (world hunts, Limsa Lominsa). Biggest reason I upgraded though was iRacing. I use Racelabs and Crew Chief with all cars drawn in the track and especially at race starts I was getting down to 40-50 fps, even with the default lock at 84 FPS. Now if I get any frame drops, it's to 80 or so, which is still more than sufficient for my display.
3080ti with 3 x 1440p. I have 1 more monitor to go. Thanks for the info, well played.
Thanks for doing this. I have 13700 with triple 1440 and was wondering if the 7800x3d would help in CPU limited situations and it looks like not by much!
Great video subbed for more
Excellent video I’ve been waiting for something like this. I have a 5800X and 4070ti at 1440P do you think it is it worth upgrading to the 58003D or not worth the small increase in FPS for the cost?
nah wait for next gen. a 5800x is very close
thx for the video, i think a lot of people will learn a thing or 2 here. And people shoudl udnerstand there will ALWAYS be a bottleneck somewhere, question is where & how BIG do you want it?
>>> Also so funny to see the AMDiiiiiP @framechaser ;)
5800X3D 6700xt, Triple 1440 and one 1080 4th monitor. On ACC with almost everything maxed I get around 70-80 fps FSR ultra quality.
Great video, thanks! I have a 4070 with a i9 processor running triple 4Ks. I actually had to manually turn down the monitors to 120Hz because the third screen wouldn’t even turn on at 165Hz. Do you think there is any wisdom in turning down the resolution to achieve a higher FPS? Then wait for the 50 series to come out which will hopefully be able to run 4k triples at 165Hz? I am pretty sure I am GPU limited because my CPU utilization is typically like 15%
Yes, your GPU is limiting the FPS. The 4070 provides similar performance to the 3080ti used in these benchmarks. And it is struggling at Triple 4K. I think it is OK to sacrifice screen clarity and run Triple 1440p so you can achieve smoother FPS. I usually race with VR and that is a common tradeoff.
Btw, CPU utilization is reported as an 'average' usage across all cores. Simulators are only demanding on about 2 to 4 cores, and the others will be near idle. Those idling cores can bring down the average to 15%, even though a couple cores may be crunching most of the data at +90% usage. So if you upgrade to 5080, the CPU utilization 'average' may not change.
What a lovely intro…! 🥳👌 I’m not into IRacing but having a look at your video was worthwhile. 😊 how come you have all those cpus ready for testing? I’m running a 5800x3d with my triples. keep it up! 👍
My friend made the music track! I'm trying to convince him to make music for other parts of my videos 😍
@@BenchmarkOdysseysoh, I had to be clearer. I like the intro music,which reminds me of the 90s, when I started with PC gaming. But the intro for me goes up to 1:40 minutes… how your words introduce us to the topic! 😊👌
I’d love to see how a 4090 would help a 7800x3d stretch out a lead, and what the latest offering from Amd can muster in the same scenario!
Great work !
I have a 7800x3d and a 4090 with triple 1440p and I dont see any better performance than you do most of the time with graphics on max PLUS FSR enabled and it will even dip into the 90's with a full grid of 27 GT4s on Red Bull ring. Without FSR enabled and it's only FSR 1 not 2.0 or 3 i believe it drops even further getting in the 130's to start and at the most taxing portion of the circuit getting around 70fps low end.
@@Sean-ps3ec , I have a Ryzen9 7900x with a RTX 4090, I;m just wondering if the 7800x3d would give any significant performance, or if I'm better off to way until the next gen 5000?x3d chip to get a measurable increase
Thanks for the data, though I'm curious as to why you described 1440p super ultrawide resolutions (mouthful that it is, or would double 1440p/QHD be a better term?) as 4K ultrawide? Rare as they are, I'd use 4K ultrawide for 5120x2160 monitors instead of 5120x1440 displays
You are correct! I got a little crossed in the dialog and shorthand, but the data is accurate to the 'pixel' resolution that was outlined :)
Thanks for this analysis, this was great.
I was running ACC stable 180fps on high/ ultra settings with triple 1080p, 32G 6000CL30 ram, rx6950xt & R7 7600.
However, racing on the Nord 24 track I've been getting anywhere from 50 to 100 fps on high settings depending on how many cars are around, time of day and part of the track.
Is it time for R7 7800x3d?
I recently did an ACC analysis with Nords for the graphics cards, and I did do a comparison between 7800X3D and 13700K, but only as low as Triple 1440p. The X3D showed a clear advantage at that track, and I suspect it will be even bigger at Triple 1080p.
Thanks I'll take a look
Awesome video!
I’m getting ready to switch to triple 32” 4K monitors once my monitor mounts arrive. I currently have an i9 12900k, RTX 4090 and 32GB of 6200mhz RAM.
Do you think I would see significant (or even decent) gains by upgrading my cpu to an i9 14900k?
Thank you! Also, great question. The 12900K would sit somewhere between the 12600K and 13700K in my performance results for the torture test at Daytona, but the 3080ti constrains FPS results at Triple 4K. RBR has higher FPS because of the lighter load on the CPU, but again the 3080ti bottlenecks at Triple 1440p and 4K.... so that's where your 4090 would shine.
So in most racing scenarios, I think the 12900K should be able to push to your monitors max refresh rate, or close to it.
14900K is best for those who want top-end performance without the hassle of overclocking, and Intel charges a hefty premium for that. AMD's Ryzen 9000 may be out Q3 this year, and Intel's Arrow Lake is probably Q1 2025. Investing $600 into either of those platforms, instead of 14900K, will probably yield much better results.
@@BenchmarkOdysseys I appreciate the reply! That was my original plan was to just upgrade when the next gen comes out. I had heard iRacing was pretty intensive on CPUs which is what brought me down the search trail to this video. Nice to have peace of mind about it though!
Thanks again!
Well this answered a lot of questions I've had for CPU behavior in Iracing, turns out the extra L3 cash on the AMD 3D is worth it when pusing high res, or rather when getting close to max GPU use.
3D V-Cache works really well with iRacing! Especially now that I've tested AC and ACC and seen several instances where X3D loses its advantage.
Of note (for iracing), the reverse also applies for running a new cpu with an old graphics card.
I recently upgraded from (a now) ancient 7700k (4 core) to a 7800x3d (8 core) system, while still running a 980ti (6gig), and I gained a total of 0 fps.
I was a little disappointed, but I'm only 2 or so months off getting a new gpu (waiting on super cards to come out in January), so not a big deal.
edit : running triple 1080p
Interesting! It looks like the 980ti is just beneath the 1070 in regular gaming, although it does have 8GB. Are you running triple screens, or single screen?
@@BenchmarkOdysseys Triple 1080p.
I think the main issue is the 6gb. At tracks like the new Zandvoort, I max out gpu ram usage (set 5.2 in game), so I'm guessing it's swapping things in and out per lap, and that is hurting overall fps. Either way, I'm only getting 50-70fps at zandy, whereas at other older tracks I'm still getting 110-130fps (and they come in under the 5.2g video ram I have set in game). I do run a fair amount of graphics on, pretty much identical to what is in your video, bar I turn in car mirrors off (and only use virtual mirror).
@@ianjameslake Gotcha, makes sense. Do you have Mem Swap Cars enabled? I've read that it has been tweaked recently to help VRAM constraints
Ye bro you wont gain any FPS running triples on a 980ti just by upgrading the CPU. But now you have a great foundation for when you do upgrade your card :)
@@BenchmarkOdysseys Yep, Mem Swap Cars is enabled.
I probably just need to turn off enough textures to get under the limit, and then fps would improve decently. But it only really affects me at a few tracks atm, so it's not too much of a worry.
Great video... thanks. I seem to think that my system (i9 10900K, 3090FE, 32Gb DDR4 3200Mhz) is starting to to become CPU bottlenecked on iRacing so would like to run some similar benchmarks to find out. What software did you use to run the benchmarks? I'm pushing triples (7680x1440) on DP for iRacing with a 4th upper monitor (34" UW 3440x1440) which either has static windows open or occasionally runs the Lovely Racing pit dashboard, so I'm pushing everything quite hard.
That's a great processor! I was looking for a used 10th generation Intel to test, but it was cheaper to buy new hardware than eBay prices :| 'GPU Busy' is a beta feature with apps that use PresentMon, so there's a few different tools out there. The video posted by Gamers Nexus is full of information about this metric and how to interpret the results, I recommend you check it out! th-cam.com/video/5hAy5V91Hr4/w-d-xo.htmlsi=BtwIcxK8lHmU4nhT If you're just looking to evaluate your own hardware, the Intel app is slick and easy to use.
Great work! The little 0.2% lows of the 7800x3d are indeed interesting. I'm wondering, did you notice any thermal throttling?
Good question. 7800X3D is a bit 'spiky' with thermals; there's some inefficiencies with the IHS and people have shown great thermal improvements with delidding the processor. With my testing, however, I used Noctua D15 on the AM5 and the temperatures never approached the throttle limit, and the clocks remained boosted during the tests.
Someone needs to lend you a 4090 and 7800XT,7900XT and a 7900XTX! I really enjoyed that.
lol yes, all the cards! I'd really like to do a Radeon vs. GeForce comparison in VR and triple screens.
Would love to see comparison of 7900XTX and 4080. I think that the Nvidia cards just have advantages over AMD for triple screens in particular. But would love to see this proven!
Question, does IRacing favor Radeon or nvidia cards? Lets say new build, 1440 Tripples, 7900xtx vs 4080 super with one of these top 2 CPU’s you tested . My current rig is old now, 8700k and 1080ti hybrid running single…yes I want to build a new one and run 4 monitors. Thanks
In my video comparing 6700XT to 3060Ti, they traded 'wins' for average FPS using triples within iRacing. But when the Radeon lost... it lost by a bigger margin than when the GeForce lost. This suggests that Nvidia is the better choice, but I have not tested the latest generation from AMD.
Thank you for this video!
I'm kinda "struggling" with my setup. 12700KF (@4.9/3.8 fixed), 4090, 3x1440p. At race start the fps is somewhere between 70 and 90 every time, with some dips below 60 (even with 20 shown cars). During race it's absolutely fine, but based on MSI Afterburner the CPU is max 40%, GPU is around 50%. Maybe it should worth to upgrade to a 14700KF. You gave me a great idea with this CPU Busy stuff, many thanks for that! Hopefully I'll see where the bottleneck is in that scenario.
I have a 7800x3d with a 4090 and while Im seeing 130fps to 150fps with FSR enabled it dips into the 90's and 80's with/without FSR enabled with my usages around 30% tops on CPU sometimes hitting 40%, but most of the time staying in the 20's to 30's. And GPU usages sit at around 60% almost all the time. This is with maxed out graphics minus foilage and crowd (Personal preference)
@@Sean-ps3ec what I can find interesting is that 8P cores are running on 50-60%, other 8P cores are 1-2% and 4 E cores are just doesn't doing anything.
So this might be some parallelization issue...
Will I have problems running triple 1080p monitors if I have a Ryzen 7 3700x with a RTX 2070 Super? Only 2 display ports as well, so I would have to be using DP and HDMI I’m assuming.
Usually it's ok to mix HDMI and DP. You can expect to see better performance than R7 2700 with that CPU, and the 2070 Super will perform similar to the 3060Ti which I benched in one of my other videos. So expect good FPS after some normal tuning!
What gpu do you recommend for a i7-9700k at default 3.6ghz...and would overclocking to 5ghz make a difference for a gpu? For running triple 1440p 120 fps
Thanks
How similar would a 4070Ti (12gb) setup be? Considering it has a 192 memory bus but is technically faster than the 3080 Ti's 384 memory bus.
Unfortunately I do not know! Considering the power draw (and thermal) advantage of the 40 series, and the compute efficiencies gained, I suspect the 3080ti may perform very similar to 4070ti.
This has been helpful, I'm struggling to stream with a r9 5950x, simhub and race labs running, might need to "downgrade" 5800x3d 🤔
Happy to help ;) The X3D cache will help with running iRacing. If you're running triples AND streaming, you're asking a lot of your GPU!
@@BenchmarkOdysseys I'm running a Titan XP and that's sololy for the sim on a 4k60 monitor, and have an intel Arc 380 for streaming, but when it's a large grid like Daytona and I've a Simhub dash running and RaceLabs for the stream the C and S stats go into the red and all the cars start flickering in and out. GPU normally sits around 60/70% on the Titan and the Arc sits at 30/40% while streaming. So we're pretty sure the core that IR is using can't keep up. I'll see if I can get a 5800x3d cheapish 😅
So basically get the best CPU you can afford.
If you run single screen get a midrange GPU.
If you run triples get as much GPU as you can afford.
I wish iRacing utilized DLSS. It would be nice to get 4K triples and run DLSS balanced.
I have a i7-12700k with a 3070ti using a Oculus Rift S but Im curious how a 4080, 4090 or 7900xtx would perform.
Not sure if you have the capability to test with those in maxed out graphics across the board. But itd help me out and be very insightful
VR can be very GPU demanding, however, the Rift S only requires 80Hz and it's resolution is much easier to drive than say a Quest 2 or Quest 3. I don't think you will see a noticeable improvement with iRacing, however other simulators like ACC are very inefficient and could benefit from a 4080.
I wonder how the results will compare when rain comes
I'm running an i9 9900k with an old 2070 super on triple 1440p but locked at 60hz due to a struggle with nvidia surround. I dont want to upgrade. But i know i need to. 😢
it would be interesting to see how many cores are used by Iracing and what percentage they are used for each processor.
I do not log that data, however, I do casually observe it. I generally see 4 cores not being used at all, 2 cores maxed and 2 cores above 50%. Although I do leave Intel Ecores enabled because I think only a small subset of users will disable those just for iRacing.
@@BenchmarkOdysseys Thankyou. It would seem to be true that single core performance is the best place to aim. CPU with the best single/dual clock rate when overclocked. Heat/cooling will also play a big factor. I forgot to say thanks for the video, great contribution to the community.
I'm not the most techy person by any stretch so here goes...
I'm currently running triple 1080p with a 5800x and a 3080ti....I was thinking of going to a 5800x3d in the hunt for better fps in iracing. Am I to take it then that it's not worth it the expense for such a small gain ?
Cheers.
The performance gain I saw for Ryzen 5600 to 5800X3D, was 19% to 35% at Triple 1080p. That's a solid improvement offered by the 3D V-Cache. If you run multi-class series on newer circuits, I think the 5800X3D will provide a +25% boost to your regular 5800X. In contrast. you will see smaller gains with Vees around Lime Rock Park, perhaps in the teens.
@@BenchmarkOdysseys I appreciate the reply, many thanks...From that then I'd say it's 100% worth it...With rain coming next season even more so...Thanks again and I'll be doing the upgrade.
so if im on a 5600x and setting up 1440p x 3 with a 3080, then j dont need to mobe up to a 5800x3d ?
If racing in a car with 4 mirrors around a difficult track like Daytona with 49 other competitors, the 5800X3D may offer a +30% gain over 5600 at Triple 1440p. But if you find yourself racing less demanding series like 20 competitors in single seaters (only 2 mirrors), than 5600 is within 6% of 5800X3D.
There is something weird between triple HD and 4K: If you take "1K" as an HD monitor (a 4K monitor is actually four HD monitors), then 3K (three HD monitors) is less than one "4K" monitor. However, you have better FPS in Intel 9700K and AMD 2700 in 4K, than "3K", even though you are moving more pixels (7.4M vs. 6.2M). Even more strange, GPU Busy Ratio is as expected: More busy in 4K than "3K"... Maybe something related to the sync of the three of them because you're not using Nvidia Surround?
Yes, I think you are right. Also, triple monitors require a sim to project 3 slightly different perspectives, otherwise the side monitors become skewed like a fish lens. It's a similar challenge to VR, and Nvidia offers SMP and SPS features to help reduce the performance impact of presenting those POV offsets. There's a performance advantage to Surround because it reduces the complexity and hand-off between Windows, GeForce drivers, and the sim itself.
Thanks for your quick@@BenchmarkOdysseys! So do you suggest not to use Surround and use three (separate) monitors instead in iRacing? I mean in terms of visual fidelity.
No prob :) If by visual fidelity, you mean smoothness and 'what looks best'... I'd enable G-sync and aim for an average FPS of at least 100, and 1% mins no lower than 80, but that's what looks best on my Gigabyte M28U screens. I find that easier to pull off with Surround enabled.
amazing comparison, however in sim racing 120+ fps are totally not necessary. i love 140 fps on fps titles, but for sim racing a solid and constant 75-90 is more than ok
You're welcome! I agree in that maxing out your monitor's refresh rate is a 'nice to have'. But there is variance to LED panels and monitor technology from model to model, and some handle lower FPS better than others. And even that boils down to the subjective experience of each racer.
With my eyes focused on these Gigabyte M29U monitors, the lower-limit to the sweet spot is around 90fps. When things dip below 80fps, the fluidity of the motion is compromised.
i've had very low budget used monitors for a long time before upgrading to a 4k tv. i guess people get used to everything. i was fast with an avg of 29-35 fps and I am fast now doing 100+. but I agree that if you can, why not spend more on better stuff and enjoy it more@@BenchmarkOdysseys
I have a 4090 and had a 12900KF and it wasnt enough. I couldn't get over 80% GPU usage.... every now and then I would see a spike to 84 maybe 86%. So I built my brother a computer gave him the 12900KF with my old 6800xt and got a 13900kf. Next is triples right now lg c2 48in.
13900k for the win
great video, but all this tells us is that iracing is not optimised for high cpu cores. we as a community should stop buying CPUs and GPUs to chase badly written games, but instead put pressure on the game developers to optimise their stuff. ACC is pretty much the same as iRacing
Where would the i5-13600k fit into this? Is it substantially worse than the 13700k for iracing with triples?
I’m helping my friend put together a pc for iracing, we got the 13600k but still have an opportunity to return and buy the 13700k if it’s worth the difference here
Forgot to mention probably triple 1440p. Seems like triple 1440p the i5/i7 won’t be as big of a difference?
I would not expect the 13600K to perform significantly worse. Compared to 13700K, it has 2 less Pcores (6 vs. 8) and a bit less cache, but iRacing is not efficient at leveraging 8 or more cores (as of 2023 Season 4). iRacing does respond well to faster clock speeds, and the 13600K boost to about 5% less than 13700K.
At Triple 1440p, it seems that iRacing becomes more reliant on the video card, therefore the performance differences between 13600K and 13700K should diminish. If the $100 saved on CPU go help him upgrade the GPU from 4060ti to 4070, or 4070 to 4070ti... then that would have a bigger impact on performance than a 13700K at triple 1440p, @@jmancherjeee
what card for you recommend for triple 1440p 144hz? My cpu is a i9 10850k
At that resolution, I would expect the 10850K to get about 90% GPU utilization out of an RTX 4070 12GB during a 'typical' iRacing official race. I suspect that a faster card, like 4070ti or 4080, will be less than 80% utilized with that CPU.
