Core i3-8121U is a 64-bit dual-core low-end performance x86 mobile microprocessor introduced by Intel in early 2018. This chip, which is based on the Cannon Lake microarchitecture, is fabricated on Intel's 10 nm process. This processor, which has a base frequency of 2.2 GHz with a TDP of 15 Watts and a turbo boost of 3.2 GHz, supports up to 32 GiB of dual-channel DDR4-2400.

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.
