Intel Core i7-875K 2.93GHz Unlocked Quad-Core Processor Review

The Test System

Intel P55 Platform

Before we look at the numbers, here is a brief glance at the test system that was used. All testing was done on a fresh install of Windows 7 Ultimate 64-bit. All benchmarks were completed on the desktop with no other software programs running. The Intel P55 platform that we used to test the Intel Core i7-875K processor was running the Gigabyte P55A-UD6 motherboard with BIOS F9 that came out on 5/12/2010. The Kingston HyperX memory was set to 1600MHz with 9-9-9-24 1T timings. 

Intel X58 Platform

The Gigabyte X58A-UD5 motherboard was running BIOS F5 and the 6GB Kingston HyperX DDR3 memory kit was run in triple-channel mode. The Intel Core i7-980X test system was run with the memory at 1333MHz with 8-8-8-24 1T memory timings. The Intel Core i7-975 test system was run with the memory at 1600MHz with 9-9-9-24 1T memory timings. The difference in memory speeds was due to stability issues at 1600MHz with the 980X motherboard. We feel that this was a BIOS issue and have Gigabyte looking into the matter for us.
Here is a quick look at the GPU-Z and CPU-Z specifics for our test Intel test system with the Core i7-980X in it.

AMD Socket AM3 Platform

The AMD Test System:

The test system was run in dual-channel memory mode at 1600MHz with 9-9-9-24 1T memory timings. The Gigabyte GA-890GPA-UD3H motherboard was running BIOS F7b, which was the latest build available when testing was completed.

An ATI Radeon HD 5870 graphics card with CATALYST 10.2 drivers was used for testing.
