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 980X Test System

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.
