In order to provide a good impression of the performance of the different processors, we tested them with an extensive set of benchmarks in Windows 7 64-bit.
For all processors we used a motherboard with the fastest chipset available for that platform: Intel X79 for Socket 2011, Intel X58 for Socket 1366, Intel Z77 for Socket 1155 (Ivy), Intel Z68 for Socket 1155 (Sandy), AMD A75 for Socket FM1 and AMD 990X for Socket AM3+. The test systems were equipped with 4GB DDR3-1866 memory, an ATI Radeon HD 5870 graphics card, a Western Digital Raptor 74 GB hard disk and a Cooler Master Real Power M850 power supply. We put 6GB of RAM in the socket 1366 system because of its triple-channel memory controller, while the Socket 2011 received 8GB for the same reason. We did make sure that none of the benchmarks utilised more than 4GB. The processors with integrated GPUs were also tested without a separate graphics card. For the power consumption tests we used professional energy measuring equipment.
The following pages have all the charts with test results, with our conclusion at the end. In the graphs the Intel processors are blue, the AMD processors are green, while the new Ivy Bridge processors are red.
