Core i7-920XM Extreme Edition is a 64-bit quad-core microprocessor introduced by Intel in late 2009 for the mobile market. The Core i7-920XM EE, which operated at 2.00 GHz with turbo frequency of up to 3.2 GHz for a single core was one of Intel's flagship mobile processors for the Nehalem microarchitecture, the i7 940XM being the top end model. The chip is manufactured in 45 nm process. The i7-920XM supports 32GB of memory and has a thermal design power of 55 W.

[Edit/Modify Cache Info]

Cache Organization Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory. The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC. Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies. Note: All units are in kibibytes and mebibytes.
