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 clearly has the best single threaded performance with the highest score in CB11, even ahead of the Core i7-3960X. Of course we turn on the multi-threaded version the results aren’t the same but the 3770K is still 10-12% faster than the 2600K.
 


POV-Ray 3.7

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

 

POV-Ray shows another 15% performance advantage for the 3770K over the 2600K.
 

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.

There are a lot of results here, but picking through them shows interesting results.  The Core i7-3770K is the fastest single threaded CPU tested but falls behind the Core i5-3570 at the four thread level due to the inefficiencies of HyperThreading.  Turn that thread count up to six or eight though and you see the benefits the technology can provide.
