PassMark PerformanceTest is a PC hardware benchmark utility that allows a user to quickly assess the performance of their computer and compare it to a number of standard 'baseline' computer systems. The Passmark PerformanceTest CPU tests all benchmark the mathematical operations, compression, encryption, SSE, and 3DNow! instructions of modern processors.
In our tests there were several areas of concentration for each benchmark, which are combined into one compound score. This score is referred to as the CPU Mark, and is a composite of the following tests: Integer Math, Floating Point Math, Find Prime Numbers, SSE/3DNow!, Compression, Encryption, Image Rotation, and String Sorting. For this review, we've also decided to run the memory benchmark, which results in a composite score based on the following tests: small block allocation, cached read, uncached read, write performance, and large block allocation.
In Passmark, the Intel processors again appear to have a slight advantage, with the Intel E7400 pulling ahead of the Phenom II X2 550. Reflecting on trends we saw with Everest, my guess is the Passmark CPU score has a large floating point component to it. Also interesting is the higher memory score, which directly contradicts the higher memory bandwidth of the X2 550 reported by Everest. It's obvious we'll need a few more benchmarks before we can reach a consensus.
