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 i7-7700K Review - Kaby Lake and 14nm+ - Processors 9
The single threaded results in Cinebench are actually 6% faster on the Core i7-7700K than on the 6700K while the multi-threaded score shows that delta to be around 4.8%. These are small gains, but at least noteworthy enough to compare to a generational IPC gap.

POV-Ray 3.7

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

The gap between the two competing processors sits at 4.2% (7700K over 6700K).


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.

Oddly, the Core i7-7700K is behind in Euler3D performance at every thread count when compared to the Core i7-6700K. The differences are small, but consistent.
