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.
In the Passmark tests, the Intel Core i5-2500K once again outperforms its AMD rival, the Phenom-II X4-975BE and this time by almost 9% in the CPU tests. In the memory tests, the gains are closer to 38%. This is likely due, at least in part, to the integration of the memory controller onto the die for the Sandy Bridge CPU. This will allow faster communication with the memory. The same memory was used for both systems. The only system with different memory, the X58 system, outperforms the Core i5-2500K by about 12% in the CPU tests and 14% in the memory tests.
