Aoostar GEM 12 + Oculink EGPU Full complete review Gaming Mini PC 

Yes, it's strange since this sollution only runs on 4 pcie lanes, instead of 16 as it does hooked up to the motherboard. Seen several others testing oculink with about 30% loss of performance, which is reasonable due to the considerably lower bandwidth of the oculink. Maybe this dude didn't even put the gpu in the PCIe x16 4.0 slot on his motherboard. That would explain the results he gets. I don't trust this "review" at all after seeing so many others showing different results/numbers.

@@MrMandelll No way Oculink is losing 30%, you are getting confuse with Thunderbolts PCIE 3, I thought that the Oculink would lose between 15% to 5%, most optimistic reviews i saw were talking about 3%, i knew Oculink was good but i didn t know it was that good until i watch this review, unless this channel is faking results and using desktop for testing, i swear you won t get better FPS with a Desktop or at least with my setting level ii got my RTX 4080 S Gigabyte WindForce running with my 7900X, coz i got the same FPS ranging in Cyberpunk and the Witcher ( don t know about other games he tried ), as the guy was testing setting maxed with DLSS and FR, he can t have faked settings, but could fake MSI component name and use desktop and rename to mobile, however it s interesting, i would like to see more test from other channel with my cards, but there are too few videos on Oculink with high ends cards and mobile CPU.

​@@MrMandelllOculink can Be PCIE 4.0 or 3.0. Ryzen 5000U and 5000H series are PCIE 3.0. Ruzen 6000-8000U/H are PCIE 4.0. The performance loss in PCIE X4 4.0 is minimal. PCIE 4.0 X4 = 3.0 X8. Look videos comparing RTX4090 PCIE 3.0 X8 vs PCIE 4.0 X16

Hi, thanks you for your comment, you should not be worry about latency, because the Oculink port is PCIE 4.0 X 4 and its taking the full power of the 4 lanes of PCIE 4 and is taking directly information from the GEM 12 CPU, just like a GPU would on a Desktop Motherboard unlike Thunderbolt cables You can compare my CyberPunk FPS results with with the ZwormZ Cyberpunk RTX 4080 SUPER (YT Video) results. There are no performance lost at all, even with an RTX 4080 SUPER, that's why the Oculink is a class of its own in the Mini PC world. Note that my resolution during the test were mostly made on a 3440 X 1440P display monitor.

My pleasure!

@@vlad_8011 Hi, Tks you for your comment, This video purpose is not "World Record FPS in Cyberpunk", i did a bunch of game testing and also several 3DMARKS Bench to give a maximum of reference for comparison regarding this Mini PC Model + eGPU set up. Concerning Cyberpunk I was lazy playing throught the all endless Cyberpunk Dialogue to reach the City part so i picked the fastest story to get to car driving. But yes you are right the FPS will be lower but not destroyed at all, i am preparing a new video with a new Mini PC with Thunderbolt EGPU and even with this much lower Hardware set up i am way above 100 FPS at Max setting with RT Max, it s not even close to be called destroyed, it s still in the excellent user gaming zone experience with Max Setting.

@@Ghost-Keyboard OK, i just want you to know, in Cyberpunk best setting to test is japanese area (city) with lots of neon lights.

@@MrMandelll hi, sorry but i don t understand your question, maybe you could watch my eGPU video to help you visualize the whole eGPU setting.

@@anakinskywalker7079 Hi, No, you don t have to change anything in the BIOS, if you have the same set up then it should work just fine, Rx 7900 GRE should work. 1- Check that ypur HDMI cable is connected to your monitor port, and unplug your HDMI cable on your GEM 12 if it s plugged. 2- Uninstall AMD Adrenaline followed by DDU to uninstall your previous GPU AMD drivers. 3- Reinstall AMD Adrenaline. 4- disable your igpu in Device manager in Monitor display option I hope those tip would fix your issue

@@Ghost-Keyboard no, tested. Thanks

@@anakinskywalker7079 Do you have an NVME M2 adaptator? Why have you mentioned "OCUP4 on M2 Mode (small switch on the side)"??? With the GEM 12 you are not supposed to use the NVME M2 adaptator.

@@Ghost-Keyboard No I have not. I will test again with switch on TGX position.

@@anakinskywalker7079 You don t have the same setting than me obviously, there is not such a thing as TGX position in my setting, i am sorry i couldn t help you to fix your issue.

I agree, but "hate "maybe is a too strong statement for me.

@@user-cx6rg6mr7d unfortunately RU-vid isn't allowing me to edit or post links as my channel is to small. and not allowing me too post link either in this comment, sorry for the inconvenient, i ll advice you to type "Ocup4" in the Aliexpress search bar and pick the seller with the fastest delivery and the most sold item

@@Ghost-Keyboard thank you so much!!

@@user-cx6rg6mr7d you are welcome, 😀

@@Simulati0n i am sorry you didn t like this review, i will try to do better if i ever do an other review, thank you for watching

Is it possible to connect two GPU to the Gem12? Let's say you convert one of the free M.2 PCIE4x4 slots into another Occulink port with 64gbps bandwidth. If one were to connect two separate external Nvidia GPU's to each Occulink port... would it be able to function in the same way as if you connected two separate GPU to 4x4 PCIE slots on a regular motherboard? The purpose for my question is for running large AI / LLM models, which require LOTS of VRAM. PyTorch and other AI frameworks typically allow for distributed processing across multiple GPU, pooling their VRAM together.

@@s.alizaidi6635 Hi, theorically the answer is "Yes" as the GEM 12 has 3 NVME M2 slot.
