Template:mpu Celeron 877 is a dual-core budget mobile x86 microprocessor introduced by Intel in mid-2012. The Celeron 877, which is based on the Sandy Bridge microarchitecture and is manufactured on a 32 nm process, operates at 1.4 GHz with a TDP of 17 W. This chip incorporates Intel's HD Graphics integrated graphics operating at 350 MHz with a bust frequency of 1 GHz. This processor supports 16 GiB of dual-channel DDR3-1333 memory.

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.
