This post is part “hear me out” and part asking for advice.

Looking at the table above AI gpus are a pure scam, and it would make much more sense to (atleast looking at this) to use gaming gpus instead, either trough a frankenstein of pcie switches or high bandwith network.

so my question is if somebody has build a similar setup and what their experience has been. And what the expected overhead performance hit is and if it can be made up for by having just way more raw peformance for the same price.

    Any time you need a CPU that can do a shit load of basic math, a GPU will win every time.

      You can design algorithms specifically to mess up parallelism by branching a lot. For example, if you want your password hashes to be GPU-resistant.
