Ryzen 9 5980HX is a 64-bit octa-core high-end performance x86 mobile microprocessor introduced by AMD in January 2021. Fabricated on a TSMC 7-nanometer process and based on AMD's Zen 3 microarchitecture, the 5980HX operates at a base frequency of 3.3 GHz with a TDP of 45 W and a boost frequency of up to 4.8 GHz. This APU supports a configurable TDP-down of 35 W and TDP-up of 54 W, DDR4-3200 or LPDDR4-4266 memory, and integrates a Radeon Vega 8 GPU operating at up to 2.1 GHz.

[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.
