Template:mpu Core i5-2557M is a dual-core mid-range performance mobile x86 microprocessor introduced by Intel in mid-2011. This chip, which is fabricated on a 32 nm process based on the Sandy Bridge microarchitecture, operates at 1.7 GHz with a TDP of 17 Watts and a Turbo Boost frequency of up to 2.7 GHz. The i5-2557M incorporates HD Graphics 3000 integrated graphics operating at 350 MHz with a burst frequency of 1.2 GHz and supports up to 16 GiB of dual-channel DDR3-1333 memory.
Cache
- Main article: Sandy Bridge § Cache

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. |
