Template:mpu 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 1400X operates at a base frequency of 3.2 GHz with a TDP of 65 W and a Boost frequency of 3.4 GHz. This MPU supports up to 64 GiB of dual-channel DDR4-2666 ECC memory.

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.

Memory controller

This processor incorporates 2 DDR4 PHYs, each supporting 1 channel of 64-bit data plus ECC with 2 DIMMs per channel. DIMMs of rates 1,333 MT/s - 3,200 MT/s are supported (UDIMM/SODIMM). Note that despite AMD's support for memory rates of 3,200 MT/s and possibly higher, rates beyond 2666 MT/s exceeds the JEDEC specification and is thus considered overclocking which voids AMD product warranty and likely any vendor or retailer warranties as well.
