A 64core Zen2 Epyc processor can already do realtime 8k HEVC 10bit encoding, and at 79fps to boot:

So if you only need 30fps or 24fps, or perhaps 50fps or 25fps for 50Hz territories, then you could get away with a considerably lower CPU core count.
Heck even for 60fps you could probably get away with a 48 core Epyc since, if the multi-threaded encoding scaling was 100%, you'd be seeing 59.25fps on a 48core Epyc. However, since multi-threaded encode scaling almost never perfectly scales with core-count, and since CPUs with fewer cores tend to also have higher base clocks, it'd be quite likely that you could even see slightly above the required 60fps from a "mere" 48core Zen2 Epyc processor.
