Rendering and Scientific

CineBench 11.5

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

The Intel Core i7-6700K Review - Skylake First for Enthusiasts - Processors 9
From a single threaded workload standpoint, Skylake is faster than any other CPU we have had our hands on, including the Core i7-4790K and the Core i7-5960X. Once we enable multi-threading, the 6- and 8-core platforms take advantage to pass by the 6700K but Skylake still does quite well, putting out a score that is 10% faster than Devil's Canyon.

POV-Ray 3.7

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

The POV-Ray results look very similar to our multi-threaded CineBench results, above, with the 8-core / 16-thread Core i7-5960X still dominating overall. The Core i7-6700K is able to NEARLY match the performance of the 6-core Ivy Bridge-E platform though, another nod to the capability of the architecture.


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.

While the Skylake scores in Euler3D are great to see, great single threaded results, better four threaded performance than Haswell-E and better overall performance the Haswell, the Broadwell scores stand out to me. Despite the several hundred MHz deficit in clock speed, the Core i7-5775C is actually the fastest device at 2-thread and 4-thread results and bests Skylake the rest of the way. Clearly that large eDRAM cache is useful for other purposes than just gaming!
