Template:mpu Pentium B940 is a 64-bit dual-core budget mobile x86 microprocessor introduced by Intel in 2012. Fabricated on a 32 nm process based on the Sandy Bridge microarchitecture, this chip operates at 2 GHz with a TDP of 35 W. The Pentium B940 supports up to 16 GiB of dual-channel DDR4-1333 memory and incorporates Intel's HD Graphics IGP operating at 650 MHz with a burst frequency of 1.1 GHz.
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. |
