Ryzen 7 1800X - AMD

Template:mpu Ryzen 7 1800X is a 64-bit octa-core top-of-the-line performance x86 desktop SoC 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 DDR4-2666 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 memory controller, along with much of the southbridge on-die. The 1800X includes 16 PCIe lanes for a GPU along with an NVMe controller and an additional 4 PCIe lanes for I/O along with SATA and USB 3.0 links.

[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).
