Ryzen 9 3900X And Ryzen 7 3700X: Cinebench, POV-Ray, Blender, 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

The Ryzen 9 3900X and Ryzen 7 3700X continued to perform very well in Cinebench. Here, AMD's latest processors offered single-threaded performance roughly on-par with Intel's best and their multi-threaded performance was strong as well. The Ryzen 7 3700X nearly catches the Core i9-9900K and the Ryzen 9 3900X just misses the mark set by the burly Threadripper 2950X.
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.

The overall performance trend in POV-Ray mirrors what we saw with Cinebench, but the deltas separating the processors are somewhat larger. The Intel processors showed better single-thread performance, which translated into better multi-core scaling with POV-Ray's workload as well.

Blender
3D Rendering Benchmark

Blender is a free and open source 3D creation suite that can handle everything from modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation. It has a built-in benchmarking tool that will track the time it takes to complete rendering a particular model. We used a CPU-focused BMW model for these tests here...

The Blender benchmark paints the Ryzen 9 3900X and Ryzen 7 3700X in a favorable light as well. The 12-core Ryzen 9 3900X nearly catches the 16-core Threadripper 2950X yet again. And the Ryzen 7 3700X finishes only a few seconds behind the much pricier Core i9-9900K. Versus the similarly priced Core i5-9600K, there is no comparison here -- the Ryzen 7 3700 dominates.
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...

Memory and cache bandwidth, latency, and CPU throughput all play a role in this benchmark. As such, the quad-channel memory setup and relatively high-clocked 18-cores of the Core i9-9980XE propel it into a commanding lead. The Ryzen 9 3900X and Ryzen 7 3700X, however, land in the second and third position, ahead of every other processor tested.
