Earlier this month we looked at the gaming performance in Windows 8 compared to Windows 7, and it turns out there was no difference. Afterwards our loyal readers asked us to apply our expertise to the processor performance in Windows 8, to find out whether that is better or worse than in Windows 7. Your wish is our command.
We took an Intel Core i7 3770K and an AMD FX-8350 processor and ran a number of the benchmarks we use for our processor tests. We did this in the 64-bit versions of Windows 7 and 8. We were particularly interested in the performance of the AMD processor, because Windows 7 was supposedly not optimised for a processor with modules consisting of two integer cores and a floating point core. AMD's architecture could therefore in theory run faster in Windows 8.
Our testing rig was equipped with 4 GB DDR3 RAM, an AMD Radeon HD 5870 graphics card and an OCZ Vertex 4 128GB SSD.
The charts on the following pages show the benchmark results for the Intel and AMD processors.
