Everyone knows WinRAR, so no need to explain what it is. I will compress our custom 10MB, 100MB and 500MB files using the greatest compression setting, in the ZIP format.

Cinebench 10 is another rendering program. I will run both the single-threaded benchmark as well as the multi-threaded.

WinRAR scales very well with clock speed. As one can see, the X2 550 gets first since it is the highest clock. The Athlon II follows, and finally... the E8400! The Athlon II was able to beat all its competitors once it got a speed bump. Cinebench also supports the general trend; the Athlon II falls right behind the Phenom II, but well ahead of its ancestor.
