AMD vs Intel: X86 Market Share, Zen Architecture Roadmap, and Chinese Fabless Partnerships

Intel remains the dominant player in the X86 market, while AMD holds a significant potential as a competitor, with a 7nm process already surpassing Intel's 10nm technology; according to Mercury Research Q4 2019, AMD's market share is about 5% in servers, 18% in PCs, and 16% in mobile CPUs, totaling roughly 15% overall.

AMD's business is divided into computing and graphics, enterprise embedded, and semi‑custom products. Its CPU cores are based on the Zen series, launched in 2017, with successive releases of 14nm Zen, 12nm Zen+, 7nm Zen 2, and upcoming Zen 3 (2021) and Zen 4 (2022), followed by Zen 5.

The Zen roadmap includes both enterprise EPYC and consumer Ryzen lines. AMD has released two EPYC generations (14nm Zen Naples and 7nm Zen 2 Rome), skipping Zen+. The next EPYC chips are 7nm Zen 3 Milan (expected Q3 2020) and 5nm Zen 4 Genoa (planned for early 2022), supporting DDR5 memory.

AMD's EPYC launch challenges Intel's monopoly; Intel's 10nm progress is slow, with 7nm expected after 2022 and no test samples yet, while AMD's 7nm processors are slated for commercial use in 2020, already seeing limited adoption in servers from Microsoft, Tencent, and Alibaba.

Since 2008, AMD has shifted from an IDM to a fabless model through asset spin‑offs: in 2009 it spun off its wafer fab (GlobalFoundries, sold in 2012), and in 2015 sold its Suzhou and Penang test facilities to Tongfu Microelectronics, retaining a 15% stake.

TSMC is AMD's primary 7nm and future 5nm manufacturing partner, having mass‑produced 7nm chips since 2018 and planning large‑scale 5nm production in late 2020.

Tongfu Microelectronics handles about 80% of AMD's testing, becoming the first factory to test AMD's full 7nm product line, while high‑end packaging substrates remain concentrated in Japan, South Korea, and Taiwan.

The X86 architecture dominates desktops, laptops, and over 90% of servers, with Intel and AMD holding roughly 70% and 30% of related patents, respectively, and rarely licensing them externally.

Chinese CPU manufacturers using X86 must form joint ventures with overseas patent holders; examples include Zhaoxin (desktop CPUs) and HaiGuang (server CPUs), the latter co‑owned by AMD (51%) and HaiGuang (49%) to obtain Zen licensing.

HaiGuang's Dhyana processor, based on Zen, supports up to 32 cores, PCIe 3.0, 2.0 GHz clock, built on 14nm; the Hygon line offers dual‑socket CPUs with SM2/SM3/SM4 security algorithms.

HaiGuang's C86 3185 server CPU, released in 2020, features eight cores with performance comparable to AMD's 2017 Ryzen 5 1400, and HaiGuang's procurement from the company reached 240 million CNY in 2019.
