Motherboard Testing Methodology
The Intel "Cougar Point" P67 Express chipset and its Sandy Bridge processors are new on the scene, and eventually will replace the older P55 chipset. However, Intel promises much greater levels of performance from their new platform. For comparison with the Intel DP67BG motherboard, I used an AMD 890FX-based system with an AMD 1100T six-core CPU, an X58-based system with an Intel Core i7-950 processor (whose price is a rough match for the Core i7-2600K CPU used on the P67 systems), and two additional P67 motherboards from ASUS, the P8P67 and P8P67 EVO.
Intel released a new BIOS for the DP67BG motherboard as I was partway through testing, but despite numerous attemps I was unable to flash the board to the new BIOS— the Windows-based update utility would report "Success" every time without actually updating the BIOS, and attempting to use the flash utility in the existing BIOS merely rebooted the motherboard, then shut it down after a few seconds.
I was fortunate enough to have the fastest Sandy Bridge processor, the 3.4GHz, fully unlocked, Core i7-2600K, for use in the P67 motherboards. For each P67 motherboard, I tested at both stock settings as well as the highest overclock I could achieve. Overclocking a Cougar Point/Sandy Bridge system is different from what you're used to, as I'll detail in the "Overclocking" section after the test results. I tried for the maximum overclock I could achieve with all four processor cores running under load; the results for each P67 motherboard are summarized in this chart.
The labelling of the results in the charts may be slightly confusing: the first two columns are the 890FX/AMD 1100T and the X58/Intel Core i7-950 platforms; the next six columns are all the Intel Core i7-2600K processor, at stock and overclocked speeds in the Intel DP67BG, ASUS P8P67, and ASUS P8P67 EVO motherboards, respectively.
