Ryzen 7 1800X is a 64-bit octa-core high-end performance x86 desktop SoC introduced by AMD in early 2017. The 1800X is AMD's flagship model for the AM4 socket. It is 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 up to 4.0 GHz. This MPU supports up to 64 GiB of dual-channel DDR4-3200 ECC memory.

Overview

Main article: Zen

The Ryzen 7 1800X is AMD's flagship system on chip based on the Zen microarchitecture. The 1800X integrates eight x86 cores and is the first AMD processor to support 2-way simultaneous multithreading. Sporting a base frequency of 3.6 GHz and a Boost frequency of 4.0 GHz, the 1800X is the fastest of the Ryzen processors. The 1800X is a complete SoC integrating a DDR4 memory controller, along with the entire southbridge on-die. The 1800X includes 16 PCIe lanes for a GPU along with 4 more lanes for storage (NVMe or 2 ports SATA Express).

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.
