Intel's Core 2 Extreme QX6700 follows Intel's new naming scheme to the letter. The Q signifies that the CPU has four processing cores, and the X, of course, makes it "extreme." The 6700 part of the moniker aligns perfectly with the rest of Intel's Core 2 processor lineup, as the QX6700 runs at 2.66GHz, the same speed as the Core 2 E6700 CPU. Each pair of CPUs has 4MB of L2 cache, bringing the total L2 for the entire processor to 8MB. Like other Core 2 CPUs, the quad runs on a 1066MHz front-side bus.

The QX6700 will be built on a 65nm process and is 64-bit capable. Following the trend of other Extreme Edition processors, the processor will come unlocked, which will give system owners a wide range of overclocking multiplier options.

The Core 2 Extreme QX6700 is pin-compatible with the rest of the Core 2 family. The processor should work fine with Intel's "Badaxe" 2 motherboards. Third-party motherboard manufacturers will release BIOS updates for existing Core 2 motherboards to enable quad-core compatibility. Whereas the Core 2 Extreme QX6700 will work in most existing Core 2 motherboards, AMD's "Quad-father" platform will require a new dual socket motherboard to support two dual-core processors.
