The Xeon vs. EPYC Performance With Intel's oneAPI Embree & OSPray Render Projects

LuxCoreRender was also tossed in for this open-source physically based renderer. LuxCoreRender isn't developed by Intel but does make use of their Embree library and Threaded Building Blocks (TBB). LuxCoreRender ended up being faster on the Xeon Platinum server with those Intel components, but then again most LuxCoreRender usage is done with OpenCL on GPUs.

The Tungsten physically based renderer is another one making use of Embree and does have AVX-512 optimizations, but for most of their demo scenes the AMD performance dominates where even the EPYC 7601 2P tends to outperform the Xeon Platinum 8280 configuration.

Lastly is a look at the Blender 2.80 performance on these EPYC and Xeon CPUs as a "neutral" renderer not making use of any major Intel (or AMD) software components. We've already shown Blender 2.80 performance with AMD EPYC 7002 series, so these numbers shouldn't come as much of a surprise.

Of all these CPU-based render tests carried out, here is the geometric mean. So while with some of the Intel-optimized components there were wins collected by the Xeon Platinum 8280 server, the EPYC 7742 2P server ended up being 33% faster overall. Over the previous-generation EPYC 7601 2P is an 88% improvement in the CPU render performance.
