- Our Intel i7-7700K Kaby Lake review benchmarks the CPU vs. the 6700K, 4790K, & 2600K.
Ad: Thermaltake Core P3: bit.ly/2hIZoLX
The full review is many thousands of words and has significant depth. We strongly recommend reading: www.gamersnexus...
We encountered some interesting thermal challenges with Kaby Lake, but were able to work with multiple boards and determine the culprit.

Hey, everyone! Thanks for watching. We have a lot more work to do to get the i3 and i5 series CPUs tested, and are also working on FX & AMD CPUs for the inevitable Zen benchmarks. For now, our full, detailed specs, architecture, and chipset portion of this review are in the written version: www.gamersnexus.net/hwreviews/2744-intel-i7-7700k-review-and-benchmark
Should I be worried about framerates if i buy a 3440*1440 monitor for my GTX 1080? I'm already getting as low as 59 fps in Geothermal Valley in Rise of the Tomb Raider in 1080p which makes me feel reluctant to get the 1440p ultrawide
Higher resolutions demand more from GPU side, to CPU mostly it doesn't matter what resolution you are using.
Wtf? 59 fps in 1080p with the gtx 1080? Either your drivers are not updated properly, or your cpu is a fx 4300. A gtx 1080 should be able to get 100fps average in 1440p in Rise of the Tom Raider with a minimum of 78.
go for it man some games just run better than others. with a 1080 you should have no problem @ 1440 in most situations. also anti aliasing plays a lesser role at higher resolutions, so you can get away with turning that down a bit.
D Jnsen I have a 6600k at 4.5 and my GTX 1080 is running at 2000+. Throughout most of the game it has been substantially higher fps. But parts in Geothermal Valley averages at like 65fps with dips just below 60fps
Out of all of the 7700k videos that just flooded my sub-box, I clicked this one for the facts. Keep up the great work!
Thanks for the support! We have a lot more to do with these CPUs yet. We are at CES this week, so stay tuned :)
Same here ahaha
Will you test 7600k and 7700k on Z170?
i do this with all realeas videos :D
Looking forward to your Vega videos :)
The only channel where they don't treat you like you've never built a PC before
i liked this but ive never built a pc...
CrackedDylMil So true. I like how they go deeper into the details than other channels.
The same garbage 5-10% performance improvements we've come to know and expect from Intel, now with hotter temps! Goddamn do we need Zen to deliver.
wccftech.com/amd-ryzen-review-leaked/ Don't hold your breath
Who care about a RyZen prototype ?
What are you saying? 46% is a huge step foward, way bigger than intel ever had these last years.
Btw Zen delivered
Wow thanks a lot for this video. I just bought an i7 7700k and a MSI M5 motherboard and I was shocked that my CPU temps got over 80C under full load using a Dark Rock 3 cooler. Changing the core voltage from auto to 1.200V and cpu ratio to 45 (4.5 Ghz) droppen the temps to max 65C under full load :D
I cannot wait to see this channel grow, and I have a feeling it is going to grow fast. IMO, you guys deserve to be up there with the best. Thanks for the great vids, and the honest reviews!
My daughter wants to know if the cat is a boy or a girl.
Thank you for your time!
Tuchulu
Depending if your Cat she or he..
lol
its a hesh
Great video, thank you for your time. I purchased a Skylake 6700K a couple months ago knowing that Kaby Lake was coming out and have no regrets seeing these benchmarks. I'll wait for the next generation. Oh and a great game that is very CPU intensive having used the same programs you use as well others like Aida64 and Intel Burn Test is ARMA 3. Arma 3 is super hard on the CPU in a real world application. I loved that I was able to diagnose my CPU was bottlenecking my GPU that other benchmarks didn't identify. Increasing my frequency on my CPU fixed the GPU bottlenecking and my PC is awesome now. Just thought I'd recommend Arma for benchmarking, I bought that game just for it and honestly, fell in love with it but that's another topic of discussion. Thanks again! Take care!
Oh and I meant to add I am able to achieve 4.734 on my 6700K with a NH-D15 Noctua cooler. I do have 7 3000RPM Industrial Noctua Case fans and a newly added G3 1000W PSU along with my Evga 1080 FTW. At 4.734 @ 1.345V I get temps as high as 76 under max load, 45-50 normal load and 22-24 idle. Want to note I manually clocked my CPU as like you mentioned, my Asus Maximus Hero 8 Alpha would run it around 1.35V stock.. ridiculous! Anyways. Couldn't be happier with my Skylake honestly :> I probably could push it over 4.734 but the gains I'll get would be diminishing or i'll get some other bottleneck as you mentioned when pushing the 7700K over 5ghz. Ok see ya!
So glad this channel is growing. You guys have the best coverage
ROcking w/ my 7700K (Noctua NH-D15) since last Feb/March 2017, great processor.....; on my Asus Z270A Prime, rock solid Battlefield 1 goodness!
I really won't upgrade my 4790K for this I7.. Not worth it and I think I should better wait for a new socket
Meh AMD and me ^^ Haven't treid yet but since my brother is working for one of the biggest components seller in France, and that he told me that holy shit much more RMA for AMD than INTEL, I probably will be careful considering just waiting to see a lot of benchmarks to make me try out AMD x) Will it support DDR4 tho ?
Kris L hm maybe then I'll wait for gamernexus advices cuz I feel that it's the most trustable "tester" 🤔
I just upgraded my i7 4770k by overclocking it to 4.6GHz xD
Unitae there is no need to upgrade from 4790k, probably something that came out sometime around a 9700k will be the worthwhile upgrade for you, not even zen will be worth it right now.
LUL I had a 980 and soon as the 1080 got released, I got it x)
always the most thorough and reliable reviews. Keep it up! time to say goodbye to my 2500K workhorse :(
We are testing that very soon! Excited to do so. Just got one in.
About 7% faster than my i7-6700K which I got for $175. I think I'll pass.
200mhz better to be exact.
This should be advertised as a pure scam for anyone running 3xxx series or above.
Jesus, you got a 6700k for $175? I thought I lucked out getting a 4790k for $250 on Black Friday 2015.
HipsterPolice you got a 6700k for the i3 7000 series price haha
Sometimes I'm lucky enough to find really good deals. I was able to get a 4790K for $185 last year which I got rid of for an i5-6600K because I didn't need i7 performance, but when I was able to get the 6700K new for $175 I had to jump on it.
HipsterPolice yeah i remember i got my 4690k for 170
So when is Intel going to release the i7 7777k and retail it for $777.77
And 7 cores with 7 threads cuz Intel can get away with it
and 77 watt tdp, overclocked to 7.77ghz
+Ectoska WOW 7.77ghz is a pretty nice feature!
will guarantee a 7777 cinebench score
+Ectoska You know that you'll have to pair that beast with a magnificent DDR4 RAM clocked at 7777mhz to reach that performance, right?
That "VR" sticker magically appearing on the i7 box at 00:44 really makes all the difference!
Thanks for testing the 2600K. Considering its low stock clockspeed (3.4Ghz) and the fact that it overclocks so easily to 4.4Ghz on air, would you still give that upgrade recommendation? I think it ended up so low compared to the other i7's because their clockspeeds are minimum 4Ghz. Most of us who still have this six year old CPU will be running it at +4Ghz anyway.
These were some pretty in-depth benchmarks. Thank you Steve for taking the time to do so much of them and do them properly. Especially the gaming benchmarks, 1% lows and 0.1% lows are key to judging how good a game actually feels. Anandtech didn't even bother to include minimum framerates in their benchmarks, let alone frametimes or other such data.
The first gamer's nexus video I ever watched and soon after bought the 7700k. Today I am retiring that PC and and I thought I come back to this video and write this comment.
Incremental, as usual. Thanks for the review!~
Excellent review, I like the full narration so I can just listen and not miss anything.
Great video, I'm still using a 2600k running at 4.5ghz and I was putting off upgrading until I could see some benchmarks from the new generation. Some interesting gains but nothing game changing. Think I will keep will my current cpu for now at least until the prices come down for the 7700k and instead for now put my money towards upgrading my GTX970.
I bought an i7-6700k last month. Thank god im not regreting it after watching this video.
Oh man, I've been waiting for this GN video!
Gigabyte had the same problem with Z97 and Devils Canyon 4790k. Check out Jayz2cents video on it. It was pumping 1.4volts at idle into a 4790k. I dont think they have a very good QA/QC.
+Gamers Nexys Why is nobody saying anything about the potential TIM issue? Is this not an issue that matters now? I heard if you changed the thermal paste, between the chip and the lid, you could potentially get 30 degrees better temps.
Thanks for the great lookup, I'm looking forward to the rest of the lineup. I'll still be holding to the 2600K out of nostalgia but without expecting glorious framerates anymore, rip master tier (I wonder how those old cpu would compare at the same speed though).
@gamer nexus
thanks for continuing to benchmark the sandy bridge series - so many people still have those chips including me. I'm going to be upgrading to a 7700k soon :)
I wonder if delidding is going to become a thing again with these chips. It certainly appears that heat transfer to the IHS could be a problem. The only question is how Intel put the IHS on and if it's removable this generation.
I'm looking at potentially getting a high end CPU for the first time in a very long time, and Intel isn't doing a good job of compelling me to go 7th gen i7. Going to wait and see what happens with Ryzen.
After CES will you be de-lidding the 7700k and checking the thermal performance? I've heard there is a massive difference.
Hoping to.
I've heard that as well, and given what I've heard about Intel's TIM choices since Sandy Bridge, that doesn't surprise me.
Hey Steve,
I am planning to upgrade on the X99 platform during next year (mostly because I need more PCI lanes). But I wonder if there is also an offering for the AM4 platform with simular PCI lane count (in this case 28 or more)? Couldn't find any information about that.
Probs to you and the GN team for bringing this awesome content.
if the SR3 Rysen goes for 150-200$, the i3 7350k is DOA
Check this out before you speculate too much. wccftech.com/amd-ryzen-review-leaked/ In gaming the Zen 8c 16t is worse then a 6700k. I will wait til real benchmarks for both come out before I make too many predictions.
If SR3 Ryzen is 4cores 8 threads, and cheaper than 7350k, it'll kick 7350k's ass.
prototype of Ryzen. Who care ? We need benchmark with the final product ;)
John Totten
rysen doesnt have to be at skylake/kaby lake standards. the SR3 will be like a 3770k, ill take that over a BS dual core i3 for 180 lol
what are you smoking that you are going to get a 8 core zen for under 200 hahaha
4 core 8 thread for 80 bucks? xD
with broadwell ipc?
you really think that amd doesnt want to make money?
the 8 core compared to a 6900k will cost at least 500 bucks.
source: pulled out of my ass and some economics classes
my 2600k still kicking strong :')
Especially overclocked but he talks it down here like it's a POS and not capable of shit. Watch HArdware Unboxed 7700k review, it makes the 2600k look even better! It beats out 6600k's in most gaming benchmarks!
Anyone else notice how at 22:08 the little VR sticker on the box isn't there and then a few seconds later it shows up?
Great video Steve, as always. I would've liked it either way but seeing the cat guaranteed I would click that like button.
Running 3930K @4.6 GHz, thought to get 7700K this year. Looking at this i think i'll just buy another GTX 1080 instead.
ThereWasNoFreeName same man! butbi actually bought 3930k +p9x79 deluxe 2nd hand and just paid 300$. great price/perf!!
Found a problem with it (don't know about 6700K and 7700K). With heavy loads (DOOM stage with snow, one exact room is poorly optimized, or Eve online multi client running or medium to big scale battle) with HT on i get 2 threads on same core overloaded. Sound starts crackling and game stutters, FPS drops below 30. Turning HT off completely resolves this issue. Probably this CPU, even OCed to 4.5-4.8 GHz will show less FPS in games than 6700K or 7700K runnig with same speed, and they can be clocked even higher, DDR3 instead of DDR4 will slow down a bit too, but since i use 32" 4K 60Hz display i need only stable FPS which this CPU still provides in all modern games. And even if i have DDR3 1600 CL10, i have whole 64Gb of it ))
So gaming/workloads are still good on this 5 years old CPU.
ThereWasNoFreeName Bro, if you do, you're going to be hella bottlenecked because of how many PCIE lanes your CPU can control.
isn't 40 PCIE lanes enough?
im running a 3930k @4.7 but i hear 3930k is getting outdated for streaming? would a 7700k be better for streaming or should i stick with my current CPU and just buy a 1080ti Strix?
what's with the liquid temp? is there no thermal transfer going on? it's not a direct comparison but my 5820k gets my x61 to almost 40c running folding@home for 6 hours. can't wait for a delid video!
Yeah, it's like they put toothpaste unter the heatspreader. The HEDT processors all are soldered to the IHS so that the heat transfer is much better.
I don't understand why Intel just doesn't put at least better TIM or liquid metal on the K-CPUs. Now you hit a fucking temperature limit before being limited by the processors capabilities so that the only option is to delid them. That sucks hard since your warranty goes down the drain. But we all know Intel doesn't care and wants enthusiast to buy their overpriced 6- and 8-cores you mostly won't need for gaming.
Let's hope Zen will do all better.
@Gamers Nexus Is the small improvement in performance between the i7 7700k Stock clock and the 5ghz+ overclock is due to the gtx 1080 bottlenecking the max fps cap ?
Thanks for adding the 2600K man!
also, is the 2600K clocked at stock speeds?
Still using the 2600k @ 4.7Ghz and wanting to upgrade but I'm really interested in seeing what Zen has to offer before letting the Sandy Bridge rest.
Great video as always, none of the other BS that's rammed down our throats from other uploads, apart from OC3D Tom is a top bloke with top content like GN. Would be awesome to see Tom and yourself (Steve) do a tech show together, time difference may be a problem.
This not apples to apples comparison. I would like to have seen a 4.6GHz overclock for all cpus. Something that should be achievable. Then overclock each to max overclock at 1.35 volts.
We do not purchase K series CPUs to not overclock.
I would love to see that too
Thanks for all the hard work. While Kaby Lake on the whole is underwhelming, those OC results are definitely impressive.
Im still rocking an Ivy 3770K at 5ghz which has an IPC almost the same as the 7700K stock. Going to wait one more generation i think.
Anything faster/ newer than the 2600k should wait, the improvements are snail paced as always.
Gigabyte - The MB manufacturer that doesn't learn. They already had that voltage problem with Haswell/Devils Canyon boards/cpus. Stock voltages so high that even with improved cooling that 4790K I used would throttle or even outright crash on the Z97 UD5 BK. Bringing the voltage down from nearly 1.3V (stock!!!) to a more resonable 1.15V solved all the problems. Now that system is running 24/7 since 2 years.
I'm not sure if I will want to upgrade quite yet. My 4930k is still very competitive with it's 160MHz base clock and 4.3GHz core clock across all 6 cores all the time. It manages to keep both my Strix 1080's fed nicely.
Out of everything you talked about, the cat was the best deal. Beautiful cat by the way.
why skip ivy bridge? i wanted to see how my i7 3770k at 4.7 compares
Just started watching and I know this will be the definitive review!
Interesting tests with temperatures. I would like to see temperature comparisons with older CPUs (2600k,4790k, etc) with overclocks on those to match the temperatures of the 7700k. If both are overclocked with similar high end coolers, how would the performance look in your tests? It appears the 7700k's gains in performance come at the cost of temperature. Well, just overclock the old stuff. Boom there's your performance gains. If Intel is deciding to push consumers into higher end cooling situations to get the performance gains its new CPU offers, how does it hold up when the methodology is applied to previous generations?
the i5 2500k oc to 4.3 is the most revolutionary CPU of all time, what a shame to see such despicable improvements to now.
Thanks for the indepth benchmark
Not surprising that the 7700K is barely faster than the 6700K. When I need to upgrade I'll probably try to get my hands on 6700K for cheap or I might just see what Ryzen has in store for us.
Also a side note for those who are looking to get Kaby Lake and use only the iGPU, it doesn't work properly on Windows 7/8.1.
In my recommended section right now there are 5 videos about Katy lake which were just uploaded around 49 mins ago lol
If Kaby Lake can change it's clock rate 1000 times a second, how many times per second can Skylake do it?
Congrats on 80k subs!
Kaby lake is just the "optimize" step in Intel's new development cycle, right? So does that mean that the next generation they make will be a brand new architecture? Hopefully their next architecture will actually bring better performance than this, I'm getting a little tired of 1% performance improvements between Intel generations. At least they seem to be feeling some pressure from AMD Zen already, I'm pretty sure that's why they finally decided to release an unlocked i3, which in my opinion is the most interesting thing about the Kaby Lake release, because up till now i3s have kinda sucked and one of the main reasons to go with a budget AMD CPU like the Athlon 860k over an i3 was that the 860k is an actual unlocked quad core, but the i3 was locked, and the unlocked Pentium has massive frame drops and stutters so it's not really a valid choice anyway. I'll be very interested to see Zen quad core CPUs benchmarked against the unlocked Kaby Lake i3 and i5.
You just took a Skylake retail box and added a "VR" sticker post production XD
With these small increments in performance, AMD has a real chance to catch with Intel. I really hope they do, then Intel can wake up, and make some proper performance increments.
So basically it's more like Skylake but overclocked higher and allow higher voltage which make it operate in higher temps ?
i could swear the VR logo on the CPU box is moving (or NOT moving, while camera does) added during edit ?
Did Steve just hint that Ryzen benchmarks are coming next week?
No. Definitely not. But I probably said that there'll be news at CES this week, which is a very safe assumption.
Yep.
I tend to lose track of what Steve says due to his flowing locks keeping me mesmerized...
Really wish GN could dig up an Ivy Bridge CPU to add to the bench-marking mix. Also be nice to add mid-range GPUs (1060/480) results to the mix to see how lower demanding graphics affect the disparity of Intel generations.
My guess is a 1060/480 won't show as great of a disparity between Sandy Bridge, or perhaps Ivy Bridge, to Haswel and beyond. Or maybe I'm just hoping my Ivy Bridge system isn't too outdated for the new mid-range cards ;)
4.5ghz seems to be the sweet spot on games no point on pushing higher considering the heat & power output.
Skip this generation and wait for Cannonlake in 2018.
or PapaLake in 2019
I'm not buying new until CrazyLake in 2020.
Please tell me more about how silly Intel naming methodics are.
Cant do, my dual core is getting too slow.
Nah, i still have an i7-950. Will build a new PC with Kaby Lake. Tired of waiting.
So... STILL no huge reason for me to upgrade my 3770k @ 4.5GHz.
Save me, AMD. Save me from the mediocrity.
I wouldn't count on AMD giving you a better chip then Intel, everything I see is they are trying to deliver a chip comparable to Intel. The only benefit with AMD is it will probably be cheaper but performance wise, you'd be better off sticking with Intel if I could guess. Speculation of course but so far I've seen nothing to suggest otherwise. Just carbon copying competition. We'll see though. See ya.
you mention it overclocks to 5.1ghz well, yet the 7700k reaches 70C+ with a Kraken X62 at 4.5ghz. What am I missing? New to OC'ing and temp management.
If the clock changes that much frequently, what guarantees that we won't have worse battery performance because of just that? This seems like a solution for a problem that doesn't exist.
The disturbing conclusion should be: wow, Intel, you lazy bunch of marketers, just marginal performance jumps between 4790K and 7700K.
I'm sticking with Haswell. Plus the Z97I-Plus is one of the best ITX motherboards I've had and now hard to find.
great video as always !
Love the in depth information!
I'm still rocking a 3930k @ 4.5ghz. I still don't see any reason to upgrade what so ever.
up to 82c? Is it normal to let cores go that high these days? I've always kept them under 70c thinking even that was a bit too high. If up to 82c on stress tests would be safe for my 2500k maybe i'll play around with it and see how far i can push it.
Is there a possibility to download the .blend file of the Blender benchmark?
I'd love to directly compare your results with my PC.
So intel realised a couple of the kabylake cpus today (3rd Jan) but official release is on the 5th of January? Please reply if this is right or correct me if I'm wrong.
Can you do CPU testing under my stressful circumstances? Like live streaming a game using CPU encode and playing a music in the background for a good measure. Was wondering how big of a difference does an i7 make when compared to i5 under these situations.
Please include OC'd Sandy in the upcoming tests. I would be really interested in it as an owner of 4,8GHz 3770K.
I don't understand why there is no i7 3770k or some ivy bridge processor in the benchmark
Given the falling costs of the 4790k, with the ability to reuse my ram, I think these benchmarks suggest that it's the best route to upgrade from my i5 2500k? I'd still be able to use my Windows7 OS as well
And here i sit with my 1.st generation Nehalem 920 7 years later, still disappointed in the new generations.
yo dawg, i heard you like sevens... i7 7700 in 2017
Great review :) I'll be ditching my almost 6 year old 4.5ghz 2600k for a 7700k soonish : D
80k subs! Keep it up GN :)
A little high auto voltages, mine does 1.232v auto on 4.5Ghz, 60ºC on Aida 64
Guess it's better now, after all the bios updates!
The countdown of Skylake's relevancy begins. Hoping my 6500 lasts at least 5 years.
moral of this video, if you got a 4790k KEEP IT ! :P
I have an i7-4790K overclocked to 4.8GHz and I'm just rendering H.265 at the moment. Just doing fine ;)
So 2011 to 2014 was 30%-40% improvement, and 2014 to 2017 is like 10%-15% improvement? Yaaaaaaaaaaay.
I would like to see the benchmarks with all CPUs clocked at 4.2 Ghz, just to see the IPC gain. I think 2600k does a lot better when pushed to 4.5Ghz+.
It has no IPC gains..
Brian Jules I know it has no gains going from 6700 to 7700, but i want to see the gains from 2000, 3000 and 4000 series. Stock 2600k is only at 3.4 Ghz base. It overclocks to 4.5 Ghz+ pretty easy.
ahh ok, I get what you are saying.
So I just got a asrock 270z itx-ac 7600k and in the bios it shows the cpu idle is 51c but on the desktop every software I download shows it around 33c. I have been looking for hours to find a answer and I've got nothing but other OPTIONS. can you please guild me? This is my first biuld and I feel like all the reading I have done is useless.
I'd say it's about time to upgrade my 4.5GHz 2600k. She's served me well!
I went with the 7700K on a gigabyte z170x-designare board with the corsair h110i v2 cooler. The system runs well, Doom 1440p/144hz@144fps, but i noticed the core voltage is set to 1.35/36 and bounces around a lot from 1.1-1.4. Should I lock down the cpu fluctuation on voltage and lock its speed? i've only been modifying the lower multipliers, setting them around 48 for best stability. CPU runs 50-60*C under load, averaging ~55*C.
Looking at this now and seeing the Voltage the board was using on the auto setting is insane because at 1.4V (the Voltage that board was trying to use on auto) I am able to run my 7700K at stable 5.2GHz at 1.4V while this was tested with the CPU at it's max boost frequency on all cores, just 4.5GHz.
What if I have a 4770k that refuses to overclock and is thus stuck at a measly 3.5GHz? It invariably crashes with anything past its stock speeds (has been tried in multiple boards(. Would this (or zen) be a worthwhile upgrade for me?
"innovation"
Why nobody makes a benchmark with 6700k vs 7700k at same clock speed? I only find benchmarks like this one in wich they only overclock the 7700k.
Wondering how the 7600k will OC. Also to hell with Gigabyte and their auto settings. They have been overvolting CPUs since Haswell. Been very happy with MSI boards lately.
"Tortured with Fourier Transforms". I feel you, 7700K bro. :'(
Moral of the story is there's no point in overclocking the 7700k for gaming.
