Cinebench R11.5 64-bit

Download from: www.maxon.net

Cinebench R11.5 uses Maxon's Cinema 4D engine to render a highly-complex, photo-realistic scene. This scene contains reflections, ambient occlusion and procedural shaders, so it gives a CPU a tough workout.

As Cinema 4D is a real-world application - used on films such as Spider-Man and Star Wars - Cinebench R11.5 can be viewed as a real-world benchmark.

WPrime

Download from: www.wprime.net

WPrime is a multi-threaded maths calculation benchmark that counter-intuitively uses square roots rather than prime numbers. The standard benchmark uses 32 million numbers, calculating the square root via 'a recursive call of Newton's method for estimating functions.' You can read the full blurb on WPrime's About page. WPrime scales well across multiple CPU cores, and can push a CPU to 100 per cent load on all its cores.

To run the benchmark, first visit the core count to check that WPrime will load all physical and logical cores, and then run the 32M test. The results are expressed in terms of the time taken to calculate the square root of the set of numbers (32 million in the standard test). A lower score is better.
