A family of x86 CPUs for laptop and desktop computers from AMD. Introduced in 2017, Ryzen was designed to compete with Intel for regular desktop PCs as well as gaming PCs, and dozens of Ryzen models have been released with four to 64 cores. Super high-end Ryzen chips sell for a thousand dollars and more.
The first Ryzen chips were based on AMD's Zen microarchitecture and 14 nm process technology. In 2018, the second-generation Ryzen Threadripper chips were enhanced with the Zen+ architecture and 12 nm nodes. Ryzen nodes were subsequently reduced to 7 nm (see
process technology).
AMD's Athlon chips are also widely used, and by the end of 2021, Ryzen and Athlon chips helped AMD account for nearly 40% of the CPU market. See
