Worth pointing out this is specifically regarding "cpubenchmark.net", not "cpu.userbenchmark.com" or anything else from User Benchmark, which is known to have a heavy bias against AMD.

I'll have to look into whether there's some public API to pull cpubenchmark score as I agree, it'd be immensely useful.

To your other point, EPYC and Threadripper are listed now:
