Multi-Threaded Rendering, Fluid Dynamics, Power

Cinebench R15 is a 3D rendering performance test based on Cinema 4D from Maxon. Cinema 4D is a 3D rendering and animation suite used by animation houses and producers like Sony Animation and many others. Cinebench is very demanding of processor resources and is an excellent gauge of computational throughput.

Cinebench R15
3D Rendering

This is a multi-threaded, multi-processor aware benchmark that renders a photorealistic 3D scene (from the viral "No Keyframes" animation by AixSponza). This scene makes use of various algorithms to stress all available processor cores. The rate at which each test system was able to render the entire scene is represented in the graph below.

We've included a single-core result here to show any generational improvements between Haswell and Broadwell. And although the Xeons are clocked lower, they still managed a higher single-threaded score. It is in the multi-threaded test, however, where the 2P Xeon E5 v4 setup really shines and outruns the desktop chip by almost 3.4x.

POV-Ray Performance
Ray Tracing

POV-Ray, or the Persistence of Vision Ray-Tracer, is an open source tool for creating realistically lit 3D graphics artwork. We tested with POV-Ray's standard 'all-CPU' benchmark option on our test machines, and recorded the scores reported for each. Results are measured in pixels-per-second throughput; higher scores equate to better performance.

Although we specified the use of 72 threads in POV-Ray, the benchmark never fully utilized more than 36 cores, hence the similar results for both Xeon tests. Even with only half of the compute resources being used though, the 2P Xeon E5 v4 system significantly outpaced the 5960X.

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.

Though this benchmark can leverage many processor cores, it is also affected by other platform limitations like memory bandwidth. The 2P Xeon E5 v4 server offers much more memory bandwidth and significantly more compute resources and virtually doubles the speed of the 5960X.

Total System Power Consumption
Tested at the Outlet
Throughout all of our testing, we also monitored how much power the Xeon E5 v4 server consumed using a power meter. Our goal was to give you all an idea as to how much power the system was using under various workloads. Please keep in mind that we were testing total system power consumption at the outlet here, not just the power being drawn by the processors alone.

This power consumption data tells an interesting story in our opinion. In terms of absolutes, nothing appears to be out of the ordinary. We have seen many powerful test systems idle in the sub-200 watt range, and have seen peak power consumption much higher than 505 watts, especially when testing high-end gaming systems with multiple GPUs. But none of those systems had 36 physical CPU cores and 256GB of RAM. Considering the immense horsepower of this 2P Xeon E5 v4 server, that fact that it pulls only slightly more than 500 watts from the wall is quite impressive.
