Today we will be introducing you to three new Core i7 processors based on the new Intel Nehalem microarchitecture, each featuring 4-cores and operating in the 2.66 to 3.20GHz range. Like the Core 2 family, these new processors feature model numbers, designed to keep things simple.
The Core i7 965 Extreme Edition runs at 3.20GHz and features a QPI (QuickPath Interface) throughput of 6.4GT/s, which is the key difference here. The mainstream versions of the processor include the Core i7 920 and 940, clocked at 2.66GHz and 2.93GHz, respectively. These more affordable processors feature a QPI throughput of just 4.8GT/s, so it will be interesting to discover what kind of impact this has on performance.
