Normally Corona should render correctly on any hardware regardless of whether the CPU is manufactured by AMD, Intel or any other exotic vendor, so mixing AMD and Intel CPUs in a render farm is perfectly safe.
However, we’ve just discovered a bug in CScatter causing slightly different results on AMD vs Intel in some very specific situations. We’re currently working on fixing this.
Heya, can you shed some light on your configuration? I’m investing in 2x extra threadrippers as well - any reason why you’re going to AMD? Didn’t Intel come with a counterpart for the threadripper?
