About Zhaoxin Semiconductor

Zhaoxin, formally Shanghai Zhaoxin Semiconductor Co., Ltd., is a fabless semiconductor company established in 2013 as a joint venture between VIA Technologies and the Shanghai Municipal Government. The company was created to develop domestic Chinese x86-compatible central processing units (CPUs), graphics processors (GPUs), and chipsets, reducing China's reliance on foreign technology. The formation involved an initial investment of $250 million, with a venture capital firm of the Shanghai Municipal Government holding the majority share. VIA Technologies, a Taiwanese semiconductor company, provides the crucial x86 license required to produce compatible microprocessors, which it obtained through its acquisitions of Cyrix and Centaur Technology.

The company's business model is centered on the design and sale of its processors to business clients, primarily hardware manufacturers and system integrators. Zhaoxin's processors are designed for a range of applications, including desktop computers, laptops, servers, and embedded systems, with a strategic focus on the domestic Chinese market. Its product families include the KaiXian (KX) series for consumer and business PCs and the KaiSheng (KH) series for servers and data centers. Architecturally, Zhaoxin's initial processors were based on VIA's Isaiah microarchitecture, but the company has since developed its own designs, such as WuDaoKou, LuJiaZui, and YongFeng. While generally targeting the low-to-mid-range market segment, recent developments like the KX-7000 and KH-50000 series demonstrate significant progress in performance and core counts, aiming to compete more closely with established players like Intel and AMD.
