Render TestsCineBench 10
This rendering benchmark based off of the Cinema 4D engine is a terrific indicator for multi-threaded processing.
In the single-threaded workload the Core i7-860 is only 2% slower than the i7-870 but is about 7% slower overall in the multi-threaded version of the test. However, the Core i5-750 falls behind the i7-860 by as much as 20%.
POV-Ray 3.7 Beta
POV-Ray has long been the poster child for multi-threaded processing and rendering.
Similar results are seen here in our POV-Ray rendering test as the benefits of a slightly higher clock and HyperThreading clearly give the Core i7-860 an edge over the Core i5-750.
Blender is a free open source 3D engine that is a popular choice amongst college students and small developers.
And once again the Core i7-860 and i7-870 are very close in performance clearly giving the edge to the lower cost part in terms of performance per dollar.
