Ryzen 3 4300U is a 64-bit quad-core entry-level performance x86 mobile microprocessor introduced by AMD in early 2020. Fabricated on TSMC's 7-nanometer process based on AMD's Zen 2 microarchitecture, the 4300U operates at a base frequency of 2.7 GHz with a TDP of 15 W and a Boost frequency of up to 3.7 GHz. This APU supports up to 64 GiB of DDR4-3200 or up to 32 GiB of quad-channel LPDDR4x-4266 memory. This chip integrates a Radeon Vega 5 Graphics operating at up to 1.4 GHz.

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

[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.
