Template:mpu The Core i7-940XM Extreme Edition is a 64-bit quad-core microprocessor introduced by Intel in early 2010 for the mobile market. The Core i7-940XM EE, which operated at 2.13 GHz with turbo frequency of up to 3.33 GHz for a single core was Intel's flagship mobile processor for the Nehalem microarchitecture. The 940XM is identical to the i7-920XM but with a faster clock. The chip is manufactured in 45 nm process. The i7-940XM supports 8GB of memory and has a thermal design power of 55 W.
