Ryzen 5 4500U is a 64-bit hexa-core mid-range performance x86 mobile microprocessor introduced by AMD in early 2020. Fabricated on TSMC's 7-nanometer process and based on AMD's Zen 2 microarchitecture, the 4500U operates at a base frequency of 2.3 GHz with a TDP of 15 W and a boost frequency of up to 4.0 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 Radeon Vega 6 graphics operating at up to 1.5 GHz.

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

Cache[edit]

Main article: Zen 2 § Cache

[Edit/Modify Cache Info]

hierarchy icon.svg 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.
