Up until this juncture we have talked about features and specifications that generally apply to the entire Intel Core i7 Processor family. It's now time to focus solely on the i7-920 and look at the features this processor brings to the table that cause it to be called the Extreme Edition. The Core i7-920 derives its 2.66 GHz clock rate by multiplying the system's 133MHz base clock by the i7-920's standard multiplier of 20. Unfortunately the i7-920 has a locked multiplier the only exception is when turbo mode is activated and the conditions are right; in this case turbomode will automatically boost the base clock multiplier of 20 to 21, giving the you essentially 133 MHz of extra processing power without ever touching the first setting.
