This has been one of those features we were planning to do soon after Core i7 launched, then had to put back. Before we go any further, we should say thank you to Corsair for being patient with us, but we felt we had to address the key questions with this new architecture first, before reviewing memory. After all, if you don't know how long a yard stick is, how can you tell if other sticks measure up well? If you've been living under a rock the last few months, or you're new to the field of performance hardware then lets have a quick Core i7 CPU and memory architecuture refresher.

For the first time in the Intel camp, the Core i7 CPU now houses not only its execution cores, but also an "Uncore" area that also contains the memory controller, L3 cache and QPI interconnect to the X58 northbridge on the motherboard. The "Uncore" area runs at a different frequency to the CPU cores, so it's essential to know both these values which are indicative of performance and overclocking potential.
