Oculink Vs NVME M2 Vs Thunderbolt EGPU Battle

[@coolchews08]

I really love this kind of test on egpu! Great job! No one on KZbin is doing what you are doing!!

@@coolchews08 Hi, Thanks you so much fir your warm comment, i really appreciate 😀

[@ll_spud]

Thanks for this. This is exactly what I wanted to know.

You should have connect the thunderbolt to aostar eGPU 4:03, instead of the NVME eGPU.

[@Ghost-Keyboard]

@@w2385-i2s Hi, Why? I already made a video about the AG02 Thunderbolt Vs Oculink.,The TishRic 40GB/s was giving me a better host to device connection speed than the Aoostar Thunderbolt

[@lewzealand4717]

Great comparison! I used a TB3 eGPU in 2017 and performance was pretty good everywhere but then I built a gaming PC. Returned to TB3 in 2024 and found that some games tank performance like Forza Horizon 5 here while others are OK, just a bit slower like CP2077 and GOW. Got an Oculink PCIe4 x4 as a fun tester and it delivers consistent performance in all games unlike like TB3 (Hogwarts Legacy and others). Good to know NVMe is just as good as Oculink.

[@Ghost-Keyboard]

Yes, you are correct, it all depend of the game, some games will take advantages of the 64GB/s Oculink data transfer speed and will deliver more FPS at the exit point, but some less demanding games will do just fine with the 40GB/s Thunderbolt speed.

[@SydneyMud]

We can clearly see at 2:35, you only powered two 8pins of 4080. Did you later powered the 3rd 8pin before running the test? Or left the 3rd 8pin unpowered?

[@Ghost-Keyboard]

@@SydneyMud Hi, Sure i did, the RTX 4080 S won t work with only 2 X 8 Pins, i made dedicated video for EGPU set-up with the RTX 4080 S with detalied step by step. You can find this video on my channel.

[@anthonylipke7754]

If the Oculink dock also used thunderbolt why put it through nvme adapter that might introduce variation? or did you try both and the one you used was better? As you mentioned nvme was showing dipping variation 1% lows might be helpful to show that for comparison.

[@Ghost-Keyboard]

@@anthonylipke7754 Yes, you are correct i could have used the AG02 Aoostar Thunderbolt port as on paper it has one less layer to connect to PCIE, however CUDA Z shown that data transfer speed of the 2 set-up are very, very close. But yes it would be a good idea to compare the Performances of both Thinderbolt eGPU set-up 👍

i do wish you got more view. awesome video!

So do I

[@gerrygumelarkarmana4065]

can you share the model of the NVME to Thunderbolt converter enclosure ? is it ACASIS 40 GBps ?

[@Ghost-Keyboard]

@@gerrygumelarkarmana4065 Hi, Sure the model is "TishRic" 40GB TB3/TB4 compatible, i got it on Aliexpress for 35-40$

[@gerrygumelarkarmana4065]

@Ghost-Keyboard do you get, good score on read and write while using this converter ? AFAIK score for 40GBps around 3600 Mbps right ?

[@Ghost-Keyboard]

@@gerrygumelarkarmana4065 Yes, Each connection speed have been mesured and it is in the video.

[@coolchews08]

What happens if I use m.2 oculink adapter on a laptop that has a dgpu, will it automatically overwrite the dgpu?

[@Ghost-Keyboard]

@@coolchews08 No, it won t, you must select the desired GPU (eGPU) in Windows "Device Manager" in the "Display Monitor" option and possibly disable your dGPU or even uninstall the drivers of your dGPU, in some case you won t have to uninstall your dGPU drivers. Usually you will have to uninstall your dGPU drivers if its an AMD eGPU and your GPU running on the eGPU is sn NVIDIA GPU, there is no one way to correctly set up your eGPU but several ways.

[@coolchews08]

@@Ghost-Keyboard when connected to oculink m.2 adapter with rtx4060ti, the laptop recognises it but when I disabled my gtx1650 dgpu, it only reads or uses my intel xe graphics igpu. Not sure how to make it read or use my 4060ti But when using tb3, I have no issue

[@Ghost-Keyboard]

@@coolchews08 have you tried to disable both intel Xe igpu and GTX in windows device manager?

[@coolchews08]

@@Ghost-Keyboard yes I have but once I did that, the laptop is very sluggish

[@coolchews08]

I’m using AliExpress m.2 oculink adapter with minisforum deg01 oculink dock, don’t think that is the issue?

[@WickyMa-u3j]

For my Mini PC is using Thunder Bolt 3 Cable connect, the result is very not stable, If iI Jump to NVME M2 Egpu will be more stable? please let me understand.

[@Ghost-Keyboard]

@@WickyMa-u3j Thunderbolt isn t by nature unstable compared to NVME M2, but NVME M2 will grant you a considerable performance boost depending of the game and setting because NVME M2 has a bigger bandwidth.

[@mouzzi_]

how about thunderbolt vs. usb4 (asm2464pd chioset) ??

[@Ghost-Keyboard]

@@mouzzi_ Hi, All my Thunderbolt eGPU setting (AG02 + Thishric adapter) are 40 GB/s asm2464pd Chipset. Do you know a Thunderbolt eGPU model that is not asm2464? Maybe some older model of ADT-link or Razor X?

[@asimsabir]

I have Huawei Matestation S, CPU = Ryzen 5 4600G, I have Nvidia 4060 Inno3D, and want to use as EGPU. The processor is PCIe 3.0, I have NVME port inside the motherboard which I am going to use with oculink dock. I already ordered Oculink dock with 50cm cable please if you can prepare a step by step guide as to how it will be done secondly I am concerned about the PCIE express 3.0 , will it limit bandwidth ?

[@asimsabir]

The Bus Interface in GPU-Z = PCIe x 16 3.0 @ x 16 3.0 (IGPU)or (APU) CPU-Z Mainboard Bus specs PCI- Express 3.0 (8.0GT/s) Graphic interface Bus PCI-Express 4.0 current link width. x16 current link speed. 8.0GT/s max supported = x16 max supported link speed = 16.0 GT/s

[@Ghost-Keyboard]

@@asimsabir Hi, PCIE 3 will indeed get you more performance loss but not only your CPU is Zen 2 and is DDR4 RAM which will also get you more performance loss compared to Zen 3 DDR5 at with higher frequency, i don t have any idea of the performance loss percentage with Zen 2 PCIE 3 CPU with an Oculink/NVME M2/Thunderbolt eGPU. Will it work? Yes absolutely! but you will have more performance loss than with Zen 3 PCIE 4 set-up, but as your GPU is a Powerful RTX 4060 which support DLSS3, you can expect huge performance gain with high setting gameplay at 1080P or 1440O with AAA games, in other words an eGPU set up for you is a good option. About the Tutorial, i made several tutorial on eGPU, if you watch my videos you will find all the steps needed for successfully set up your eGPU. Actualy i have scheduled videos, i will make new tutorial eventualy if i get a new eGPU, Thanks you for your comment

[@asimsabir]

thanks brother, I am a playstation player, and this desktop I am using since years, my target is decent fps on 1080p if its fulfilling my needs I will go for it I will update you once the dock arrives.

[@Russiangamerpro2021]

It'll be nice if you put the new device which is I have it's called the Lenovo Legion go because for me it has U USB4 port which is made a contrast for 40 gigs of bandwidth means I can connect it to my EGPU so that'd be nice if you get a type handled which is the Lenovo Legion go just to Test the new Handheld

[@Ghost-Keyboard]

Privet, kak dila droug 😊 I have just received the GMKtech K8 Plus with the 8845HS a few hours ago, so my next publication will be the review of the K8 with an Oculink eGPU, unfortunately i am not into laptop review so i don t think i will be able to review the Legion Go any time soon. About Thunderbolt eGPU working on your laptop, if you have a USB 4 port then there is a high probability that it support Thunderbolt as you told me that your transfer speed is 40 GB/s, i don t see any reason why a Thunderbolt eGPU wouldn t work with the Legion Go. Have fun and a nice week end RussianGamerPro 😊

[@_GarethRossUK]

But this isn't true on all graphics cards, the G1 for example gets a 15-60% boost on Oculink over USB 4.

[@Ghost-Keyboard]

@@_GarethRossUK Hi, data can also vary from one game to an other and as you said from one card to an other card

[@ishanayush1611]

Is the nvme 2.0 pcie 3.0 or 4.0

[@Ghost-Keyboard]

@@ishanayush1611 Hi, PCIE 4 on all eGPU's and CPU is also PCIE 4

[@ishanayush1611]

@Ghost-Keyboard do you think it a good upgrade if I pair my laptop's ryzen 5 4600h with a egpu RTX 4070 or something and after using it for a while I would build a seperate pc

[@MadMaxJoe]

Interesting, i thought Oculink was special, but it is equal to NVME

[@jaskier5586]

is thunderbolt and usb 4 different? if yes and usb 4 is faster then thunderbolt, is it fast enough to have almost the same speed with m.2 or not?

[@Ghost-Keyboard]

@@jaskier5586 Hi, Thunderbolt is a protocol that is build with USB 4, All Thunderbolt Connection are USB 4 but not all USB 4 support Thunderbolt, but in a very large number USB 4 support Thunderbolt 4 which is under Intel License. No Thunderbolt can not match an NVME speed as Thunderbolt is 40GB/s data transfer speed and NVME is 64GB/s speed, however as you have seen in my test Thunderbolt in the majority of games will not be that far from NVME type and is still a very good option to upgrade your system graphic performances.
