◆ Test Description

The Sandy Bridge which we got default frequency is 2.8GHz, but because it is not locked multiplier, you can directly increase frequency to Core i7 2600K level, it is the most high-end processor of first wave Sandy Bridge processor, the core clock is 3.4 GHz.To keep the comparison under the same frequency, we have chosen Core i7 875K, Although the default frequency is only 2.93GHz,But it does not lock the multiplier,So we can adjust to 25 multiplier,the FSB frequency set to 136MHz, So the core clock also reaching 3.4GHz.

In order to fully show performance of Sandy Bridge,the test project is very comprehensive including scientific computing, image processing, 3D rendering, video encoding, file compressing / decompressing and 3D games.

BecauseSandy Bridge process has been upgraded to 32nm, while the Core i7 875K is still 45nm, power consumption change also will be point.
