CPU Speed Professional. About the Download. com Installer. Editors' Review.
CPU Speed Professional tests your PC's processor and compares its results against other users' CPUs and systems via an online rankings site. This free tool stresses your CPU with a variety of tests designed to reveal strengths and weaknesses, but it doesn't hurt or change anything. It's basically foolproof to use and compatible with both Intel and AMD processors.
CPU Speed Professional was a lot of fun to use, both in testing our CPU and comparing the results to other PC users' machines as well as worldwide benchmarks. While the trick wears thin quickly--you can only test your chip's speed so many times--it's well worth doing, and it's free. And you don't have to share your data if you don't want to.
