To figure that out, I took RTX 4090 and RTX 2060 and connected them directly to my PC with TH3P4G3 eGPU dock. Made benchmarks not just in games, but also in applications.

FPS loss that massive such as RDR2 is often resizeable bar on EGPU vs Internal. EGPU should have resizeable bar off in nvidia drivers. Thunderbolt 4 is cutting things up into packets, which does not play nice with large memory addressing.

Fantastic test, something missing across the youtube tech channels is proper EGPU/Internal comparisons. A suggestion is to test Oculink so internal/Thunderbolt4/Oculink comparisons. Oculink is a direct passthrough. Unlike Thunderbolt 4(and 5)... it also has 50% more bandwidth then TB4, 63gb vs 40gb. Thunderbolt breaks PCIE up into packets and needs to process the signal adding delay which impacts faster GPU's more then low ontop of bandwidth limitations. PCIE Oculink Risers are that can plug into M.2 slot, and M.2 PCIE 16X4.0 PCIE cards is cheaper then the TB4 dock.

@freedomisdead9638 2 месяца назад

Oculink port are so rare, because it s too new, and using M.2 slot is messy it would require to open your laptop or miniPC and leave it open to dust also it s not convenient because most of the time M.2 slot are already busy running your operating system on M.2 SSD.

@givemeanameman1 2 месяца назад

@@freedomisdead9638Oculink is not new, its actually very old tech. it was released in 2015. The M.2 slot to oculink was a work around people found to get oculink EGPU running decently because makers wont include oculink ports on devices.

@JoseMariArceta 27 дней назад

Another caveat for this is since this is a desktop setup, the thunderbolt controller is on a separate chipset present on the motherboard and is definitely not going to perform similarly to say a laptop with an Intel cpu or amd cpu (not sure on amd) that has a thunderbolt controller on-die. There would be higher latency on this desktop thunderbolt setup so you also have to consider that part. Edit: not sure if amd has an on die thunderbolt setup similar to Tiger lake onwards for Intel, and they seem to have a worse? Implementation compared to Intel thunderbolt chips on desktop motherboards so there's that as well.

Great video, please continue with this work :) Just an idea: Maybe add some charts of your benchmark result at the end. If I got it right a 4090 has sometimes double FPS in Desktop vs eGPU. Also the RTX 2060 was a bit faster in Desktop. This results I would need somehow in a chart so I better see how big the differences are. Idea2: Also a compare to a iGPU would be nice so we would se iGPU vs RTX 2060 Desktop vs RTX 2060 eGPU. This wold give me a good overview about how much more fps I could get with a notebook (iGPU) + egpu and how much fps i loose vs RTX 2060 in a desktop and then decide if I should build a desktop system for max FPS or if i could live with Notebook + eGPU and some missing FPS^^

@trysometech52 4 месяца назад

Hey, thanks! Absolutely agree with you about some of the graphs. I could make it better. Not sure about the iGPU though, it will be different for everyone. UHD 630/770 or 780M all have different levels of performance. I don't know how you will be able to compare them to your iGPU. But I plan on doing such a comparison when it comes to Legion Go.

Performance difference might be due to fact that some cpu have embedded tb4 controller in cpu die and some doesnt. Desktop cpu most likely does not have embedded tb4 therefor no difference between i7/i9 (using same contoller on motherboard). Can you do benchmark on similar cpu (ex intel i7) but with embedded vs external tb4 ?

@trysometech52 2 месяца назад

I don't have other CPUs to test that. But most likely, it happened because of Resizable Bar. RTX 2060 doesn't support it, so we can see much more predictable behavior there

Creo que la pérdida de FPS en muchas ocasiones se debió a que la entrada de rayo tiene un GPIe 3.0 que no permite mucha transferencia de información. Hubo algunos juegos que estaban a 40 fps pero la CPU y la GPU ni siquiera llegaban al 90%, eso fue por el cuello de botella, 2 monstruos conectados por un cable GPIe 3.0 es como pasar por la aduana, solo hay 4 carriles que es más lento, sin embargo los resultados son sorprendentes, creo que si bajaras la resolución los FPS hubieran subido más en la EGPU.

Its also probably not a driver issue, you're legit putting a card through thunderbolt. It adds latency, and will make your GPU just run worse. Its just a limitation with how it works.
