AMD vs Intel: Market Share, Zen Architecture Roadmap, and the Rise of Domestic X86 CPUs

Intel remains the dominant player in the X86 market, while AMD is its biggest potential competitor, having surpassed Intel's 10nm process with a 7nm node and holding 5% (server), 18% (PC) and 16% (mobile) market shares according to Mercury Research Q4 2019.

AMD's CPU portfolio is based on the Zen family, launched in 2017 and evolved through 14nm Zen, 12nm Zen+, 7nm Zen 2, with Zen 3 and 5nm Zen 4 planned for future releases.

The Zen roadmap includes both enterprise EPYC and consumer Ryzen lines; EPYC has progressed from 14nm Zen Naples to 7nm Zen 2 Rome, skipping Zen +, and upcoming 7nm Zen 3 Milan and 5nm Zen 4 Genoa are slated for 2020‑2022, supporting DDR5 memory.

AMD's 7nm server CPUs are expected to enter commercial production in 2020, challenging Intel's slower 10nm rollout; collaborations with Lenovo and deployments in Microsoft, Tencent, and Alibaba indicate growing market penetration.

Since 2008 AMD has shifted from an IDM to a fabless model, outsourcing wafer production to TSMC (7nm and 5nm) and outsourcing testing to Tongfu Microelectronics, which now handles about 80% of AMD's test volume.

In China, domestic X86 CPUs such as Zhaoxin and HaiGuang rely on licensed Intel/AMD technology; HaiGuang, jointly owned by AMD (51%) and local partners, produces Zen‑based processors like the Dhyana (up to 32 cores, 14nm) and Hygon (dual‑socket, supporting SM2/3/4 security algorithms).

HaiGuang's recent C86‑3185 server processor, featuring eight cores, offers performance comparable to AMD's 2017 Ryzen 5 1400, with significant orders from domestic cloud providers.
