Template:mpu 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 GHz with turbo frequency of up to 3.2 GHz for a single core was Intel's flagship mobile processor for the Nehalem microarchitecture. The chip is manufactured in 45 nm process. The i7-920XM supports 8GB 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.
