- To figure that out, I took RTX 4090 and RTX 2060 and connected them directly to my PC with EXP GDC OcuLink eGPU dock.
In case you wanna get the same eGPU:

I think the most of the performance loss in rtx 2060 come From the fact the card only supports pcie gen 3 while the oculink support pcie gen 4 so the rtx 4090
You're absolutely right! I forgot about that
Have tested or just guessing
@@jussikankinen9409 yes I tested
I expected much more loss in performance, at least 30%. But this is cool. Keep it up my guy.
Saw a comment you posted on his vid a year ago when he had 17 subs, you stuck with him😎
Awesome video. I'm glad I bought an Oculink board with a metal support for the GPU to stand straight. Glad to see the review of this one.
which one did you get? I saw one with a big black base and swapable brackets for PSU but the ETA was too long...
did you try checking the bandwidth with cudaz?
in my testing, it seems aida64 and cudaz have different results
cudaz shows higher bandwidth in *MiB/s* than aida64 *MB/s*
just a weird thing
Nice i was looking for that. Love from Brasil.
Thanks for the result.
Awesome video thanks dude, just wondering about my mini pc it has 4070 12g and I want to use egpu 4090 connect them using USB c from 4090 to DP mini pc is it going to work ? I have no idea how to connect that I have DP, HDMI and USB 3.2 ports
Hej hej, where I can buy this dell adapter ? I see , )) thank you for this video.
And where I can buy this cables from 6 pin to videocard pins ?
do you recommend any PCIE oculink card instead of the m.2 version?
Was that D4 Result with or without recently added Ray Tracing? I'm assuming with, as my 4090 nets me around 100-120 @ 3440 x 1440, but I'd like to confirm.
All benchmarks was done with Ray Tracing and without DLSS in 4K. I mentioned that
awesome video
One big question that I have: what if you were to plug in the adapter over one of the M.2 slots instead? How much performance would you lose from that?
Other than that, you video was awesome and super informative, keep up the good work!
Thanks! I'm not sure I understand your question. I had it connected via an m.2. adapter, but it also PCIe 4x4.0, so it won't affect performance compared to Oculink.
I'm thinking of using this to power a 1650 and connect that to my laptop. My job requires some travel so this sounds like a good alternative and is small enough to carry around. Or does anyone have a recommendation for a small enclosure that supplies 75W?
In any case, this is the best that is now for those who want to play on portable devices from time to time, or do not want a full-size PC, or simply change devices often, and the video card remains, or during the transition period, when the entire amount for a global upgrade is not available.
Just ordered the exact same model from amazon... I'll see how it works... if it works maybe I'll try it with some pcie-cards with dual oculink ports (I can't find any with just 1 oculink port), ideally I don't want to waste an M.2 slot.
it's amazing tho. the value of the oculink is great.
what was the m.2 slot speed? gen 4?? Gen 5 should be fast enough to run the 4090 at full speed on oculink.
We need Oculink v2 for that, cuz currently max speed is 64gpbs, which is PCIe 4.0x4
@@trysometech52 it would be interesting to try a gen 5 m.2 slot and see the difference if any, because even at the x4 bus width, should be faster on a gen 5 slot. pci express 4.0x4 vs 5.0x4
Oops, comments were accidently disabled D:
Can you also make a video when it's connected through thunderbolt?
@@ChaosA1T If you hadn't skipped to the beginning of the video, you'd know that I already have it :)
Hey bro. The RTX2060 is pcie 3.0. The bandwich is the half compared ti RTX4090. 6:31
@@icaroleal7351 that doesn't matter. If you connect 4090 via Thunderbolt - the bandwidth will be the same as 2060, because Thunderbolt has PCIe 4x3.0 connection for PCIe devices like eGPU :)
I mean tree at once @@trysometech52
can you trying 1080 or 1440p to please
Was cyberpunk 2077 running in path tracing mode? If not on the 4090 could you please test that. Also can you test Control with RT at 4K and Alan Wake 2 with full Ray Tracing at 4K with as high of settings as you can run? I spy a OneXplayer X1, could you rerun the tests including that? I'd appreciate it. I'm considering the ONEXPLAYER X1 with 64GB of ram myself.
I sold my 4090 so I can’t run those tests now, but in a week or two I’ll release my review on OneXplater X1. Man…that device has a lot of troubles. Avoid it at all costs.
@@trysometech52 They've released new bios updates recently in the last 2 weeks or so. You have you get from their discord, which is shady and stupid. There's a video of the trick required that you need to do to update it. I'll be watching your review either way.
I don't like how the controller module to link them together and use them via bluetooth is still a "pre-order" thing. A channel called Barely Average Dude and he didn't like the controller.
I'm interested in the tablet style function more than the controllers as I would use a TB hub and KB and mouse. If TB5 wasn't coming out at the end of the year I would have purchased the X1, but considering it will be faster than current OCulink devices I'll used that as I want a portable that can give me at least 8x PCI-e 4.0 and TB5 will do that, getting the EGPU bay for it will be a wait. Intel already has a demo of it on their yt channel.
I’ve updated BIOS two times already, there is something more than just a software. Also AMD version of X1 will be released soon, but even that will not fix some other problems.
Isn’t Thunderbolt 5 also has 4x4.0? I think performance will be similar, but with hot swap and other features
@@trysometech52 There's a 120 Gbps option that uses PCI-e 4.0 x8. The standard mode is the x4 same as prior TB, but with PCI-e 4.0. Since the tube hates links just search for thunderbolt 5 120Gbps and Intel has videos on it and there's plenty of articles on it.
I think that’s just a marketing material. In reality TB3/4 is not 40gbps for eGPU connection (I have a video on this topic). Also they claimed x2 performance, which is exact difference between PCIe3 vs 4. So technically they didn’t lie.
El vídeo muestra que hoy en día, ya no hay diferencia entre una laptop y una PC de escritorio.
Ya estamos en abril de 2024
Y que bien, me alegra que avance a pasos agigantados la tecnología

They came out with a new one that can hold the big cards
OCuP4V2 OCuLink GPU Dock w ReDriver Chip
Yeah this one looks good, I got their Thunderbolt variant. And seems like I can fit it in the same case
How can i connect the m.2 adapter to an office laptop which I can not open?
Thunderbolt to M.2 then M.2 to OCulink.
Is there any advantage to M.2 gen 4 vs OCuLink?
No, because Oculink also using PCIe gen 4x4
Oculink port does it means HDMI?
no, it's a totally different port and connection
I wonder what it's going to be like when Thunderbolt 5 egpu docks come out. Thunderbolt 5 vs Oculink Hype!
Note that in Thunderbolt 5 or Thunderbolt 4 you don't have full bandwidth only for GPU ...
Where in Oculink you have 100% for GPU (or you can connect storage :))
Would be good compare to pci express loss.
Occulink vs direct pcie is like pcie port 4×4 vs pcie 4×8 or pcie 4×16
While I generally agree; removing the GPU from the case has thermal implications that make for some results that won't always align perfectly.
Oculink is the best
Ive been running my 6900xt over oculink/m.2 4.0 for a nearly 3 years now, and ive paired it with many systems including: a 4670k, 5775c, 3700x, 5700g, 12950hx, 13700x and 7940hs(90w) and the bandwidth is the same as the 5700g(3.0 x8) and performance is much better, definitely not 13700k but it isn’t noticeably worse, in fact its much cooler running than the 3700x, 12950hx and 13700k so thats a win. When strix halo drops with the 40cu gpu I might regress to not having a dgpu but if not ill upgrade to something with better raster than a 4090 but under 300w tdp and post 5090 and 8700xtx.
