Ryzen 9 5900X is a 64-bit dodeca-core high-end performance x86 desktop microprocessor introduced by AMD in late 2020. Fabricated on TSMC's 7 nm process based on the Zen 3 microarchitecture, this processor operates at 3.7 GHz with a TDP of 105 W and a Boost frequency of up to 4.8 GHz. The 5900X supports up to 128 GiB of dual-channel DDR4-3200 memory.

Cache

Main article: Zen 3 § Cache

[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.
