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

[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.
