5. SuperPi - RightMark
SuperPI has become a utility to benchmark modern systems. In August 1995, the calculation of pi up to 4,294,960,000 decimal digits was succeeded by using a supercomputer at the University of Tokyo. The program was written by D.Takahashi and he collaborated with Dr. Y.Kanada at the computer center, the University of Tokyo. This record-breaking program was ported to personal computer environments such as Windows NT and Windows 95 and called Super PI.
The software offers up to 32M calculations of PI numbers. At all memory settings, we tested only up to 2M calculations.
SuperPI results are directly impacted by the memory. The Crucial modules produced lower calculation times than OCZ.
Before this test packet was created there was no proper software for measuring vital system parameters such as CPU/Chipset/RAM providing steady and reliable (reproducible) test results and allowing for changing test parameters in a wide range.
Vital low-level system characteristics include latency and real RAM bandwidth, average/minimal latency of different cache levels and its associativity, real L1-L2 cache bandwidth and TLB levels specs. Besides, these aspects are usually not paid sufficient attention in product technical documentation (CPU or chipset). Such test suite, which combines a good deal of subsets aimed at measuring objective system characteristics, is a must have for estimating crucial objective platform parameters.
RightMark offers a variety of test results, including both read/write performance from synthetic and performance tests:
In the RightMark memory analyzer benchmark, the OCZ memory modules were faster than Crucial.
