Rendering and Scientific

CineBench 11.5

This rendering benchmark, based off of the Cinema 4D engine, is a terrific indicator for multi-threaded processing.

Intel Core i7-6950X 10-core Broadwell-E Review - Processors 9
Single threaded performance on the Core i7-6950X is definitely faster than that of the Core i7-5960X (by 15%) and that's a notable improvement consider we also get substantial improvement in the multi-threaded workload (33%). The performance of the Skylake Core i7-6700K is still faster for single threaded work but this new 10-core beast is 87% faster with everything turned on.

POV-Ray 3.7

POV-Ray has long been the poster child for multi-threaded processing and rendering.

The results in POV-Ray are very similar to the CineBench scores above: the Core i7-6950X is nearly 80% faster than the Core i7-6700K and 32% faster than the top Haswell-E part!


Euler 3D Fluid Dynamics

This fluid dynamics simulation is very CPU and memory intensive.  From the benchmark source website:

The benchmark testcase is the AGARD 445.6 aeroelastic test wing. The wing uses a NACA 65A004 airfoil section and has a panel aspect ratio of 1.65, a taper ratio of 0.66, and a 45 degree quarter-chord sweep angle. This AGARD wing was tested at the NASA Langley Research Center in the 16-foot Transonic Dynamics Tunnel and is a standard aeroelastic test case used for validation of unsteady, compressible CFD codes. Figure 1 shows the CFD predicted Mach contours for a freestream Mach number of 0.960.

The benchmark CFD grid contains 1.23 million tetrahedral elements and 223 thousand nodes. The benchmark executable advances the Mach 0.50 AGARD flow solution. Our benchmark score is reported as a CFD cycle frequency in Hertz.


Intel Core i7-6950X 10-core Broadwell-E Review - Processors 11


The Euler3D results show a lot of the same information we have seen in other benchmarks just pooled into a single data set. Even when running with 8 threads, the Core i7-6950X is about 12% faster than the 8-core Core i7-5960X, which tell us that some of the microarchitectural changes are coming into play. It requires 6-12 threads of work for the Core i7-6700K to fall behind the 6950X.
