How is Haiguang following the x86 route now?
The chip is the core of the underlying hardware infrastructure, and it is also the main battleground for the technological struggles of countries all over the world. In recent years, under the background of "scientific and technological innovation" and "self-reliance and self-improvement", domestic chips have also made great progress. A number of high-quality domestic CPU manufacturers such as Huawei Kunpeng, Phytium, Haiguang, Zhaoxin, Loongson, and Shenwei have risen rapidly. Among them, Loongson and Haiguang will be listed in succession in 2022.
From the perspective of architecture, Haiguang and Zhaoxin have taken the x86 route. The former obtained the permanent authorization of the x86 instruction set from AMD, and the latter obtained the phased authorization of the x86 instruction set from VIA;
Haiguang, which takes the x86 route, has continued to improve research and development after obtaining the full authorization of the ZEN1 architecture from AMD, and has mass-produced three generations of products. In addition, the x86 cross-licensing model also greatly adds points to the iterative upgrade of the product. However, due to the breakdown of Sino-US relations, AMD's follow-up Zen architecture will no longer be authorized to Haiguang. However, not long ago, Haiguang officially announced on the interactive platform that it has completed the digestion and absorption of the x86 architecture. There is also news in the industry that Haiguang's latest generation products are basically equal to ZEN3. From this point of view, Haiguang has gone well on the road of self-reliance. However, chip research and development is a long-term process, and the more advanced it is, the more difficulties it will face. Haiguang still has many difficulties to overcome in the future.
