Page 9 - Benchmark: SuperPI 1M, Cinebench R11.5
Super PI is a computer program that calculates pi to a specified number of digits after the decimal point - up to a maximum of 32 million. It uses Gauss-Legendre algorithm and is a Windows port of the program used by Yasumasa Kanada in 1995 to compute Pi to 2^32 digits.
Super Pi is used by many overclockers to test the performance and stability of their computers. In the overclocking community, the standard program provides a benchmark for enthusiasts to compare "world record" pi calculation times and demonstrate their overclocking abilities. The program can also be used to test the stability of a certain overclock speed. If a computer is able to calculate PI to the 32 millionth place after the decimal without mistake, it is considered to be moderately stable in terms of RAM and CPU. However, longer tests with other CPU/RAM intensive calculation programs will run for hours instead of minutes and may better stress system stability. While Super Pi is not the fastest program for calculating Pi, it remains very popular in the hardware and overclocking communities.

They are all within a couple hundredth of a second with each other -- but here is what lower latency memory counts the most, and memory bandwidth does practically nothing. The Ripjaws, running at 7-8-7-24, pulled up on top, but only by a hair. The rest of the bunch came in extremely close, as shown in our results above.
About Cinebench R11.5
CINEBENCH is a real-world cross platform test suite that evaluates your computer's performance capabilities. CINEBENCH is based on MAXON's award-winning animation software CINEMA 4D, which is used extensively by studios and production houses worldwide for 3D content creation. MAXON software has been used in blockbuster movies such as Spider-Man, Star Wars, The Chronicles of Narnia and many more.
CINEBENCH is the perfect tool to compare CPU and graphics performance across various systems and platforms (Windows and Mac OS X).

Our run of Cinebench R11.5 proved to be quite interesting. While one may think rendering performance will benefit from high bandwidth memory running on a high divider, our CPU based test actually preferred lower latency RAM. The G.SKILL Ripjaws scored 5.37 points, while the Pi series came in very close with a score of 5.36 running at 7-10-10-28 1T. Our OCZ Platinum XTE PC3-16000 2x2GB, with higher latencies than everyone else at 9-9-9-24, slotted nicely between the G.SKILLs and Patriot. Meanwhile, OpenGL rendering appeared to be bandwidth invariant -- the scores are ordered by the one with the lowest latency.
