POV-Ray 3.7 Beta 30	Source: POV-RAY

Ray-tracing is a rendering technique that calculates an image of a scene by simulating the way rays of light travel in the real world. In the real world, rays of light are emitted from a light source and illuminate objects. The light reflects off of the objects or passes through transparent objects. This reflected light hits our eyes or perhaps a camera lens. Because the vast majority of rays never hit an observer, it would take forever to trace a scene. Ray-tracing programs like POV-Ray start with their simulated camera and trace rays backwards out into the scene. The user specifies the location of the camera, light sources, and objects as well as the surface texture properties of objects, their interiors (if transparent) and any atmospheric media such as fog, haze, or fire.

Lower render times are better, however higher Pixel Per Second rendering values are best. Pov-ray is multi-threaded.

The Phenom II X4 910e is actually the slowest of the quad-core processors in POV-Ray, just a few tenths of a second behind the AMD Athlon II X4 620.

There's a slight increase in performance in Windows 7 for the Phenom II X4 910e processor, but not enough to really make it a winner here.
