SiFive's HiFive Premier P550 is a strange board. It's the fastest RISC-V development board I've tested—though I haven't tested a Milk-V Megrez. It's also Mini DTX, which is an ATX-adjacent standard board size that won't fit in many Mini ITX SFF PC cases, which might be why SiFive and ESWIN are releasing a custom case for it (pictured above, which they sent along with the board for my review).
Recently I've been testing a SiFive HiFive Premier P550, and as part of that testing, I of course plugged in some AMD GPUs I had laying around.
I'll get to that testing at a later date, but one thing I enjoy in my testing is finding what 3D accelerated games and other applications can be run on alternative architectures. With the great work from Wine and Proton over the years, a great many games run out of the box on Linux—and they can be made to run on Arm and RISC-V architectures with almost as much ease as Linux on X86/AMD64!
