Test assumptions

The processor we had the opportunity to test is not a commercial product – it is an early engineering version which may be very different from the commercially available end-product processors. For this reason, we have not tested it with the default operation parameters. Instead, we opted for a clock-to-clock comparison. For the shootout, we took major quad-core processors available on the market. They all operated at 2800 MHz. On all platforms, memory clocking was DDR3-1333 and latency was 7-8-7-21 1T. Turbo Mode for Core i7, Core i5 and Gulftown was off. All the power-saving features such as EIST and Cool'n'Quiet were on. The scores labelled ‘Core i5’ have been obtained using an Intel Core i7-860 processor with Power HyperThreading enabled, meaning they are different from the real Core i5 (where the uncore clock was at 2133 MHz). Note that due to the early Gulftown BIOS versions and the early Gulftown processor versions, the results are only approximate and may not be representative of the final product.
