Passmark Performance Test
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.
The Passmark performance tests show a much different result than the Everest tests. The stock Athlon-II X2-255 was outperformed by the Dual-Core E5300 running at just 2.6GHz. When overclocked to 3.8GHz, the X2-255 ADX255OCK23GQ was able to eke out a slight performance gain over the stock Intel Dual-Core. The performance increase over the 1.8GHz Core 2 Duo was very evident in both the stock and overclocked states of the Athlon-II X2-255.
In the memory marks, the AMD X2-255 did register very slight gains over the Dual Core E5300, but only by a little, even running DDR3 memory over the DDR2 on the Intel platform. I have realized through many other testing setups that the Passmark memory marks generally have very little difference based on memory clock speed, but I think we should have seen a bigger difference between the DDR2 and DDR3 memory.
