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

While officially supporting up to DDR4-2666, this processor can support much higher frequencies (3200 or even higher have been observed) with proper motherboard support. Additionally, while not officially supported, this processor also has ECC memory support (although it has not been validated for such capabilities).
