We measured the time each CPU took to compress five high-resolution 48-bit uncompressed TIF images, each one with around 70 MB, to RAR format with the popular WinRAR application. The results below are given in seconds, so the lower the number the better.

On file compression using WinRAR Phenom II X2 555 was 8% faster than Pentium E6300 and 6% faster than Athlon II X4 620. Athlon II X4 635 and Core 2 Duo E7500 achieved the same performance level.

With a GeForce 9600 GT installed, Phenom II X2 555 was 10% faster than Pentium E6300 and 5% faster than Athlon II X4 620, with Athlon II X4 635 and Core 2 Duo E7500 achieving the same performance level once again.
