Domestic x86 processor Dhyana started production: just IP authorization

The Chinese-made Dhyana x86 processor, manufactured by chip manufacturer Haiguang, started production. It is worth noting that the chip was developed based on AMD Zen microarchitecture. AMD licenses x86 IP to Chinese partners, Dhyana It is the result of cooperation.

From the official statement, AMD did not sell the final chip design to Chinese partners, but allowed partners to design their own chips for the Chinese server market.

The Dhyana processor is very similar to the AMD EPYC processor. Linux kernel developers point out that the vendor ID is different from the product serial number. In fact, Linux maintainers even transferred the EPYC support code to the Dhyana processor and found it successful. Run, which shows that the difference between the two processors is small.

For decades, the x86 architecture has been dominated by Intel, AMD and VIA. In 2016, AMD announced a joint venture in China to develop processors. AMD will receive $293 million in cash, when AMD's finances were in trouble and have been in continuous In the sixth quarter, there was an operating loss. In addition, AMD will also receive royalties. According to sales, once the processor starts production, it will earn revenue.

The localization of chips is China's long-term goal. What kind of help will the AMD licensing agreement bring? I don't know yet. In fact, before the company, Weixin Semiconductor signed a cooperation agreement with VIA, which is producing x86 chips. Overseas dependence is the ultimate goal.
