AMD Phenom II X4 975 & 840 Review

Testing:

Office 2007 Excel Big Number Crunch: This test takes a 6.2MB Microsoft Excel spreadsheet and performs about 28,000 sets of calculations, consisting of many of the most commonly used calculations in Excel. The measure of this test is how long it takes to refresh the sheet.

Lower Is Better

POV Ray 3.7: This program features a built-in benchmark that renders an image using Ray Tracing. The latest versions offer support for SMP (Symmetric Multiprocessing), enabling the workload to be spread across the cores for a quicker completion.

Higher Is Better

Geekbench 2.1 provides a comprehensive set of benchmarks engineered to quickly and accurately measure processor and memory performance. Designed to make benchmarks easy to run and easy to understand, Geekbench takes the guesswork out of producing robust and reliable benchmark results.

Again, the X4 840 was on par with the Athlon II X4 and the X4 975 was the leader of the Phenom II quad-cores.
