I haven't found anything for the Vega 8 that would run on Linux.

? I have had OpenCL on my 4900HS for awhile, just through the Mesa OpenCL driver.

I believe my really old Llano (2011) APU even had OpenCL support. It was a selling point at the time.

Same, it just works on my Debian powered home server with 5800H with just the Mesa ICD installed.

Not that it really matters for me, I only run wgpu compute stuff over Vulkan for my experiments.

Hm, now I have to start asking questions of my OS.

For what it's worth, my Llano kept hanging up when I tried.

You are probsbly just missing the driver, some linux distros dont ship it by default.

If you are on Windows... shrug.
