Cinebench

The test procedure consists of two main components: The first test sequence is dedicated to the computer's main processor. A 3D scene file is used to render a photoreaslistic image. The scene makes use of various CPU-intensive features such as reflection, ambient occlusion, area lights and procedural shaders. During the first run the benchmark only uses one CPU (or CPU core) to ascertain a reference value. On computers that have multiple CPUs or CPU cores and on those that simulate multiple CPUs (via HyperThreading or similar technolgies), Cinebench will run a second test using all available CPU power.

POV-Ray 3.7

Pov-Ray is a raytracer which comes with an integrated benchmark routine that allows CPU single- and multicore performacne. Therefore a predefined 3D-Scene is being rendered twice by the CPU and as a result you get a PPS (Pixel per Secon) value.
