It is possible to use it freely and it is way small compared to PCMark etc.

When it comes to benchmarking Hackintoshes (PCs hacked to run Mac OS X), Geekbench is pretty much the standard. It's free (screw the commercial 64-bit mode), your results are easily comparable with others on the internet, and it works on both Windows and Mac. So if you're dual-booting to both Windows and Mac, you can check whether your Mac installation was successful or not by comparing it to your Windows installation.
