AMD created the Ryzen family of semiconductor processors.
Advanced Micro Devices introduced Ryzen desktop processors in 2017, based on its Zen microarchitecture. The launch marked a major competitive return in the consumer CPU market after years in which Intel held a stronger position in performance and market share. Ryzen products later expanded into laptop, workstation, and server-related segments.
AMD also develops Radeon graphics products and EPYC server processors. It is primarily a semiconductor design company and relies on outside foundries, including TSMC, for manufacturing many advanced chips. This differs from Intel’s historical model, which combined chip design and substantial in-house manufacturing. AMD’s market capitalization is shaped by expectations for CPUs, graphics, data-center products, and artificial-intelligence accelerators.
