Rendering and Scientific

CineBench 11.5

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

Ivy Bridge-E: Intel Core i7-4960X Processor Review - Processors 9
We already saw the somewhat disappointing single threaded results of IVB-E on our clock for clock page, but here they are again.  Under the multi-threaded workload though the new CPU shines and outpaces the Haswell-based Core i7-4770K by 31%.

POV-Ray 3.7

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

POV-Ray continues the exhibition of multi-threaded performance advantages for the 6-core Core i7-4960X, showing an 18% advantage over the top Haswell SKU.


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.


Ivy Bridge-E: Intel Core i7-4960X Processor Review - Processors 11


Euler3D always gets complicated with 6-core processors as once you cross the 4-thread test on this application the quad-core processors begin to stall out.  But even AT four threads, the Core i7-4960X is 14% faster than the Core i7-4770K indicating some threading issues (HT at work) that don't show up in the IVB-E results until the 6 to 8-thread jump.  Regardless, the highest rate that the Core i7-4960X outputs is 7.985 Hz compared to 4.946 Hz on the Core i7-4770K, a difference of 61%.
