PCMark04 and 05 are applications-based benchmark and a premium tool for measuring overall PC performance. It uses portions of real applications instead of including very large applications or using specifically created code. This allows PCMark04 to be a smaller installation as well as to report very accurate results. As far as possible, PCMark04 uses public domain applications whose source code can be freely examined by any user.

For the first time with PCMark04, the P5LD2 reported better overall performance but the newest PCMark05 had a different opinion.
