I am building an AMD Ryzen PC, and want eGPUs. Thunderbolt is extremely limited, but I’ve recently seen OCuLink. For example, AOOSTAR AG02 supports USB4 and OCuLink.
The AOOSTAR AG02 is more expensive than some Thunderbolt options, so I’m looking around. What options do I have for non-Thunderbolt eGPU?
You’re building a PC but you want an eGPU? Why? Thunderbolt and occulinks bandwidth limitations have some pretty huge impacts on performance. Why would you want to pay more money to get worse performance?
For laptops eGPUs make sense, but desktops? Not at all.
Thanks for mentioning this, I’ll think about it.
In short, I have a very niche requirement for multiple (at least three) GPUs, but want an mATX build. Performance is unimportant, it’s all for a prototype
If you’re prototyping then why not get a “bench” PC. Basically one that’s on its side and the case is just a frame. They’re designed for people who are tinkering with their PC and constantly swapping hardware.
Whatever you’re prototyping you probably want to prototype the actual use case and not something that maybe 1% of the market share uses.
I have other reasons to want a normal, small PC. I don’t expect to change the hardware much once I get it. I will consider the other approach, but in the mean time I’d like to know what the eGPU options are.
The prototype involves sending a small amount of data between devices, and doing some small calculations. I expect to get 3050s, and even those will be massive overkill. I’m specifically prototyping sending data.
