Template:mpu Ryzen 7 1800X is a 64-bit octa-core top-of-the-line performance x86 desktop microprocessor introduced by AMD in early 2017. The 1800X is AMD's flagship model based on their Zen microarchitecture, fabricated on a 14 nm process. The 1800X operates at a base frequency of 3.6 GHz with a TDP of 95 W and a Boost frequency of 4.0 GHz. This MPU supports up to 64 GIB of dual-channel non-ECC DDR4-2400 memory.

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.
