Ryzen 7 3800X is a 64-bit octa-core high-end performance x86 desktop microprocessor introduced by AMD in mid-2019. Fabricated on TSMC's 7 nm process based on the Zen 2 microarchitecture, this processor operates at 3.9 GHz with a TDP of 105 W and a Boost frequency of up to 4.5 GHz. The 3800X supports up to 128 GiB of dual-channel DDR4-3200 memory.

Cache[edit]

[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.
