The AMD EPYC 9965 2P configuration was leading a clear majority of the benchmarks carried out, as would be expected. For those wondering about AmpereOne, unfortunately, I don't have any AmpereOne hardware in my possession for being able to carry out fresh performance benchmarks there.

👁 OSPRay Studio benchmark with settings of Camera: 1, Resolution: 4K, Samples Per Pixel: 16, Renderer: Path Tracer, Acceleration: CPU. EPYC 9965 2P was the fastest.

Besides the core count advantage and more memory channels, the AMD EPYC 9965 processors with having AVX-512 and the full Zen 5 ISA capabilities really help it out in a number of workloads -- with software never being able to make up those lofty differences.

👁 Intel Open Image Denoise benchmark with settings of Run: RT.hdr_alb_nrm.3840x2160, Device: CPU-Only. Xeon 6980P 2P was the fastest.

Intel's Open Image Denoise is the latest example of where AMX with Granite Rapids is helping massively.
