Their GPU's suck ass but the CPU's are fine. The X3D is easily the best CPU for VRChat and VR in general.
You won't find much non-anecdotal evidence on the GPU issues because by nature, this isn't something you can easily quantify. All I know is that AMD doesn't support certain shader features or only supports them halfway/in a weird way. And I'm not talking about RTX or anything silly like that, I mean actual shader features like alpha to coverage which is weird on AMD.
Certain cards or certain driver versions had issues for MONTHS in VRC's early days where the most popular toon shader was just invisible on AMD graphics cards.
