Ryzen 3 4300U is a 64-bit quad-core entry-level performance x86 mobile microprocessor introduced by AMD in early 2020. This processor is based on AMD's Zen 2 microarchitecture and is fabricated on a 7 nm process. The 4300U operates at a base frequency of 2.7 GHz with a TDP of 15 W and a Boost frequency of 3.7 GHz. This APU supports DDR4-3200 and LPDDR4-4266 memory and incorporates Radeon Vega Graphics operating at 1.4 GHz.

This model supports a configurable TDP-down of 10 W and TDP-up of 25 W.

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.
