File Compression

7Zip is free archiving tool and strong alternative to popular WinRAR. Integrated benchmark scripts are used in both 7Zip and WinRAR to test the performance of CPUs with multithreading enabled. One real life test with WinRAR is simulated while measuring the time needed to compress a ~700MB image file. We can see that multithreading support does not work so good like it does in benchmark scripts.

Just like video encoding, AMD's processors seem to love working with archives and show really decent performance levels. Note the big performance impact in WinRAR test between Athlon II X4 and Phenom II X4 running at same clocks.
