Core i7-2840QM is a 64-bit quad-core performance embedded mobile x86 microprocessor introduced by Intel in late 2011. This processor is manufactured on a 32 nm process based on the Sandy Bridge microarchitecture and operates at 2.4 GHz with a TDP of 45 W and a turbo boost frequency of up to ? GHz. The i7-2840QM incorporates Intel's HD Graphics 3000 integrated graphics operating at 650 MHz with a burst frequency of 1.3 GHz. This processor supports up to 32 GiB of dual-channel DDR3-1600 memory.
This specific model was only sold to a number of selected OEMs, featuring a 100 MHz speed bump over previous model.
Cache
- Main article: Sandy Bridge § Cache
[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.
