PCMark is a computer benchmark tool developed by Futuremark to test the performance of a PC at the system and component level. In most cases the tests in PCMark are designed to represent typical home user workloads. Running PCMark produces a score with higher numbers indicating better performance. Several versions of PCMark have been released though scores cannot be compared across the different releases since each includes different tests.
Controversies
In a 2008 Ars Technica article, a VIA Nano gained significant performance after its CPUID changed to Intel. However this could be explained by the way Intel compilers work.
