Template:mpu Celeron G3902E is a 64-bit dual-core x86 budget mobile microprocessor introduced by Intel in late 2015. This processor, which is based on the Skylake microarchitecture and is manufactured on a 14 nm process, has a base frequency of 1.6 GHz with a TDP of 25 W. This processor incorporates the HD Graphics 510 GPU clocked at 350 MHz with a max frequency of 950 MHz.

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.
