Ryzen 5 1400 is a 64-bit quad-core mid-range performance x86 desktop microprocessor introduced by AMD in march of 2017. This processor is based on AMD's Zen microarchitecture and is fabricated on a 14 nm process. The 1400 operates at a base frequency of 3.2 GHz with a TDP of 65 W and a Boost frequency of up to 3.4 GHz and an XFR of 3.45 GHz. This MPU supports up to 64 GiB of dual-channel DDR4-2666 ECC memory.

Cache

Main article: Zen § 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.
