Intel Core i7-3840QM is a high-end processor announced in the third quarter of 2012. It is part of the “Ivy Bridge” generation and operates at a base frequency of 2.8GHz. If a higher frequency is needed, its four cores can automatically overclock, and if they all operate in tandem, they can reach 3.6GHz. The frequency can go up to 3.7GHz for two cores or 3.8GHz for only one core.
The chip is equipped with 256KB of first level cache, 1MB of second level cache, and 8MB of third level cache. The Core i7-3840QM has been developed using a 22nm process, allowing for the integration of the Intel HD Graphics 4000 controller. It operates at a base frequency of 650MHz, while Turbo Boost can increase that to 1300MHz. Power consumption of the whole SoC (System on a Chip) amounts to 45 watts with a maximum operating temperature of 105C.
Intel Core i7-3840QM supports TurboBoost (increasing the clock frequency when necessary), HyperThreading (additional virtual core for every physical one), PCI Express 3.0, up to 32GB of DDR3/L-RS 1333/1600 memory, AVX2.0 and the SSE4 instruction set.
