AMD 2nd Gen Ryzen Threadripper 2950X And 2990WX Review: Beastly Zen+ Many-Core CPUs
AMD Ryzen Threadripper 2950X & 2990WX: 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.

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.
In yet another dominant performance, the Threadripper 2990WX once again crushes the competition in the multi-threaded POV-Ray test. The 2990WX's massive core / thread count churned through this test nearly 50% faster than the Core i9-7980XE. The rest of the numbers played out similar to Cinebench's with the 2950X outpacing the 1950X by a decent margin, but trailing the high-end Core i9.

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...
*AMD Threadripper 2990WX (b) Results = 16 Cores Enabled, With UMA Memory Configuration
Intel's monolithic, many core processors with quad-channel memory have a clear advantage here, and once again it appears that the NUMA memory configuration of the Threadripper 2990WX when all-cores are enabled drags its score down. With 1/2 of its cores disabled and a UMA memory configuration used, the 2990WX's performance jumps up and nearly catches the higher-clocked Threadripper 2950X.
