Intel Xeon W-3175X Review: Supercharged 28-Core Skylake-SP

Intel Xeon W-3175X - Cinebench, POV-Ray, Fluid Dynamics

Cinebench R15 is a combination CPU and OpenGL 3D rendering performance test based on Cinema 4D from Maxon. Cinema 4D is a 3D rendering and animation tool suite used by animation houses and producers like Sony Animation and many others. It's very demanding of system processor resources and can utilize any number of threads, which make is an excellent gauge of computational throughput. This is a multi-threaded, multi-processor aware benchmark that renders and animates 3D scenes and tracks the length of the entire process. The rate at which each test system was able to render the entire scene is represented in the graphs below.

3D Rendering Benchmark


Just like we saw with Blender, the Intel Xeon W-3175X jumps out in front of the Threadripper 2990WX again in Cinebench, and took the top spot in the multi-threaded test, but this time by a much wider margin. The Xeon W-3175X also outran all of the AMD processors in the single-threaded test, though the higher clocked Intel CPUs are better in this regard.

POV-Ray Performance
Ray Tracing Benchmark

POV-Ray, or the Persistence of Vision Ray-Tracer, is an open source tool for creating realistically lit images. We tested with POV-Ray's standard 'one-CPU' and 'all-CPU' benchmarking tools on all of our test machines and recorded the scores reported for each. Results are measured in pixels-per-second throughput; higher scores equate to better performance.

Our results in the POV Ray benchmark look much like Cinebench. Once again we see the Intel Xeon W-3175X outpacing the Threadripper 2990WX, in both the single and multi-threaded tests.

STARS Euler3d
Computational Fluid Dynamics

STARS Euler3d is a computational fluid dynamics benchmark which uses a CFD grid that contains 1.23 million tetrahedral elements and 223 thousand nodes. The benchmark executable advances a mach 0.50 Advisory Group for Aerospace Research, or AGARD, flow solution for an aeroelastic test wing. The benchmark score is reported as a CFD cycle frequency in Hertz.

This benchmark is multi-threaded, but is also dependent on platform bandwidth, and cache and memory latency, so the final results are not determined by compute performance alone. Cache sizes and memory bandwidth affect the score as well...


This is a rather obscure benchmark, but it is a good example of the benefits of Intel's Skylake-SP design, which doesn't have to contend with the shortcomings associated with Threadripper's multi-die, distributed memory controllers. As such, the Xeon W-3175X's compute resources, in conjunction with its increased memory bandwidth and lower-latency access to memory, push it to the top of the charts.
