'''Ryzen 7 1800X''' is a {{arch|64}} [[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 {{amd|Zen|Zen microarchitecture|l=arch}}, 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 {{amd|Precision Boost|Boost}} frequency of up to 4.0 GHz. This MPU supports up to 64 GiB of dual-channel DDR4-3200 ECC memory.

== Overview ==
{{main|amd/microarchitectures/zen|l1=Zen}}
The Ryzen 7 1800X is AMD's flagship [[system on chip]] based on the {{amd|Zen|Zen microarchitecture|l=arch}}. The 1800X integrates [[octa-core|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 {{amd|Precision Boost|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).
