Passmark Performance Test

PassMark Performance Test 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 Performance Test 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.

At clock speeds in the CPU tests, the Core i5-2500 here outperforms the Phenom-II X4-975BE by about 9%, and the AMD Black Edition CPU falls even further behind the Core i7-920. When overclocked to 4.0GHz, the Phenom-II X4-975BE makes up the difference and more, overcoming the lead of the Core i5-2500, but still falling shy of the i7-920 performance. With the integration of the IMC onto the die of the Sandy Bridge CPU, it really isn't much of a surprise that memory bandwidth is higher than that of the Phenom-II X4-975BE.
