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.
This software's user interface resembles a car's analog instrument cluster, with tachometer-style displays for both % CPU and MHz. A menu offered controls for initiating the scan and viewing and sharing the results. We ran the test, which involved four metrics: CPU Ramp, Core, Deep Cycle, and Cool Off. The test concluded quickly and displayed the CPU Speed ranking of our machine's processor. We clicked Submit My Score, and a Web page opened with the latest global CPU benchmarks and world speed rankings displayed. We ran the test again and received a similar score, so we opted not to resubmit it. Clicking CPU Details on the menu displayed accurate data about our processor. The tests revealed it was performing slightly better than the chip maker's published speed.
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.
