Core i3-8121U is a 64-bit dual-core low-end performance x86 mobile microprocessor introduced by Intel in early 2018. This chip is fabricated on Intel's 10 nm process and is based on the Cannon Lake microarchitecture. The i3-8121U has a base frequency of 2.2 GHz with a TDP of 15 Watts and a turbo boost of 3.2 GHz. This chip supports up to 32 GiB of dual-channel DDR4/LPDDR4X-2400 memory and has no integrated graphics processor.

[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.
