Chinese-designed "Dhyana" x86 processors based on AMD's Zen microarchitecture are beginning to surface from Chinese chip producer Hygon. The processors come as the fruit of AMD's x86 IP licensing agreements with its China-based partners and break the decades-long stranglehold on x86 held by the triumvirate of Intel, AMD and VIA Technologies. Details are also emerging that outline how AMD has managed to stay within the boundaries of the x86 licensing agreements but still allow Chinese-controlled interests to design and sell processors based on the Zen design.

AMD's official statements indicate the company does not sell its final chip designs to its China-based partners. Instead, AMD allows them to design their own processors tailored for the Chinese server market. But the China-produced Hygon "Dhyana" processors are so similar to AMD's EPYC processors that Linux kernel developers have listed vendor IDs and family series numbers as the only difference. In fact, Linux maintainers have simply ported over the EPYC support codes to the Dhyana processor and note that they have successfully run the same patches on AMD's EPYC processors, implying there is little to no differentiation between the chips.

The new chips are surfacing against the backdrop of the trade war between the US and China that could escalate quickly, likely reinforcing China's long-held opinion that a lack of native processor production could be a strategic liability. Today's wars are won with chips, and their strategic importance certainly isn't lost on those in the halls of power. In fact, the Obama administration blocked Intel from selling Xeon processors to China in 2015 over concerns the chips were fueling the country's nuclear programs, and subsequent actions by the US have largely prevented China from achieving the technical know-how and equipment to develop its own chips through acquisitions and mergers.

That makes it even more surprising that AMD has managed to establish a franchise that allows Chinese processor vendors to develop and sell x86 processors in spite of US regulations and the licensing restrictions with Intel, but now more information is coming to light about how AMD pulled off the feat.

Satisfying The x86 Cross-Licensing Agreement
AMD's announcement in 2016 that it had established a joint venture in China to develop processors was surprising, but it yielded a much needed $293 million cash infusion (in payments based on delivery dates) for the then-struggling company, which had operated at a loss for the prior six quarters. AMD is also set to reap royalties, based on unit sales, once the processors begin to ship in volume.

As part of the licensing agreement, AMD established a joint venture (JV) in China called the Tianjin Haiguang Advanced Technology Investment Co. Ltd. (THATIC) and agreed to license its x86 and SoC IP for chip development. THATIC consists of AMD and both public and private Chinese companies, including the Chinese Academy of Sciences that is heavily influenced by the Chinese government.


According to mydrivers.com, THATIC then established two companies through joint ventures: Haiguang Microelectronics Co. Ltd. (HMC) and Chengdu Haiguang Integrated Circuit Design Co., Ltd (Hygon).

But here's where things get tricky. AMD holds a 51 percent stake in HMC, while Tianjin Haiguang Holdings owns 49%. Meanwhile, AMD owns 30% of Hygon and Tianjin Haiguang Holdings owns 70 percent.

HMC owns the x86 IP and ends up producing the chips, which satisfies the AMD and Intel x86 cross-licensing agreements because the IP remains with a company owned primarily by AMD. But AMD provides the IP with the understanding that the company will use it to design its "own products specifically tailored to the needs of the Chinese server market." That requires quite a bit of maneuvering given the restrictions of AMD's x86 cross-licensing agreement with Intel.

To stay within the legal boundaries, HMC licenses the IP to Hygon, which designs the x86 chips and then sells the design back to HMC.

HMC then employs a foundry to fab the end product (likely China Foundries or TSMC). Confusingly, HMC then transfers the chips back to Hygon (the same company that designed them), which then sells the Dhyana processors.

And thus, AMD's licensing of the x86 IP stays within the legal boundaries. According to the agreement, the final products can only be sold within China's borders. That opens up a huge opportunity for AMD via royalties due to the exploding China data center market, but potentially serves a blow to Intel due to the Chinese governments' influence: China has invested heavily in native chip producers through its Made In China 2025 initiative and also offers incentives and other measures to prop up domestic chip production.

China Continues To Invest
It's unclear what the impact of AMD's licensing agreement will have on the long-term outlook for China's chip development ambitions. China is also heavily involved in other chip-producing ventures, such as Zhaoxin Semiconductor, which is working to produce x86 chips through a partnership with VIA. The combination of these efforts, among others, could ultimately provide the country with the independence it desires from US interventions, and possibly alter the long-term processor market in the process.

I don't know if anyone would disagree if I said: China has a reputation for pirating software, media and technology? One key portion of the agreement made with AMD is china cannot sell chips using AMD's IP outside of its borders. I'm not certain if that legal contract will be observed.

Years ago, china made a similar deal with russia to produce SU-27 jet fighters. China screwed russia over on that deal which soured relations between the two nations. It may not be surprising if something similar occurs here and we see semiconductor markets in the future flooded with cheap semiconductors built off AMD's designs.

Anyways, here is yet another aspect to the looming us china trade war.

If china does flood markets with cheap CPU's based on AMD's designs perhaps bitcoin CPU mining might become profitable again?   Cheesy

CPU mining in China would be the go to mining alternative since these CPUs would be much cheaper and it can be a big contribution to the crypto market in China. My only concern is that if these CPUs hit the black market it can disturb the flow of the CPU market in certain regions and it will hamper the innovation that AMD and Intel can provide as it will hit their sales. Hopefully that its sales can be regulated only in China as what the deal says so that we can still see good product from both side of the fence specially that AMD is pushing hard on Intel with its offerings.

Right country has strong economic potential, technology is also very strong and terrible. Places with good natural elements and favorable conditions. Often the place is where the wealthy people are, because they also find out where they are going. It has everything and does not have to worry about much. A place to exchange advantages, high security, healthy life joyful. What a wonderful country. And this AMD-based x86-based intel processor was born. Just like the super human.

Just saw this thread, despite the fact that you think china will steal and do the same outside of AMD but this doesn't means CPU mining might become profitable. You can see for example aliexpress and other china based online markets, here you'll see amazing GPUs in very cheap prices but do you really believe their GTX1080ti (manufactured with things no one knows...) will be the same as originally manufactured? If this is true, then everyone would buy GPUs from them which can roi in 1-2 months.

Another episode underlining the importance and value of a blockchain approach to protect technology patents.
It appear as if China will never cease to remain both oblivious and malicious when it comes to respecting other peoples' intellectual property   Undecided
