LGA 1200 motherboard for eGPU ?

[Larry Philips]

Hi,

 

so... I know the desktop + eGPU solution has a fair share of critics and quite a few downsides but :

- I already own an eGPU TB3 enclosure

- I already own a good graphic card

- I quite like having the ability to share my equipment between computers

 

I currently share this set-up between 2 laptops, but I'd like to also build a small footprint desktop with a beefier CPU.

This computer will be used for work and leisure and I want it small and light in order to move it between a work room upstairs and the living room downstairs.

Besides, I still want to be able to use the cards with the above-mentioned laptops.

 

So, knowing that I'm totally OK with the eGPU downsides and the small performance hit, back to the main question : is there any LGA 1200 motherboard with thunderbolt 3 (or 4) that I could use with my eGPU enclosure under Windows 10 Pro?

 

Thanks

First of all, there seems to be three Mini-ITX boards available on Newegg that have Thunderbolt ports built into the back panel, and one is a TB4 motherboard with a Z590 chipset, while the others are TB3 with Z490. https://www.newegg.com/p/pl?N=100007627 601333829 601361682 601361698&cm_sp=Cat_Motherboards_2-_-Visnav-_-Intel-400-Series_4 Or alternatively, you could get any motherboard with Thunderbolt support and get a Thunderbolt PCIe expansion card.

 

Though, unless you already have an Intel processor for this setup, I don't see why you want to get an Intel motherboard. Alternatively, there are a few AMD boards that have TB3 support (either having their own ports on the back IO or supporting expansion cards) and there is one Mini-ITX board that has a back panel port, the ASRock X570 Phantom Gaming-ITX/TB3. https://www.amazon.com/X570-Phantom-Gaming-ITX-TB3-Thunderbolt/dp/B07VXYYG7F 

For a list of other AMD motherboards with TB3 support, there's this list here, https://linustechtips.com/topic/1233452-amd-motherboard-that-supports-thunderbolt/

Isn't TB support quite wonky with AMD processors?

when the first Asrock with TB was released, I think I recall discussions on Egpu.io stating that eGPU didn't work at all.

Granted, that was quite a while ago and things may have changed.

 

Anyway, thanks for your answer!

I think it really depends on the eGPU you're using, because I'm seeing posts on the same site saying that it works, but you're welcome anyways!
