China Begins Production Of x86 Processors Based On AMD's IP (tomshardware.com)

Chinese-designed "Dhyana" x86 processors based on AMD's Zen microarchitecture are beginning to surface from Chinese chip producer Hygon. From a report: 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.

      China may be hedging its bets by investing in both kinds of CPUs: x86 and ARM.

      Some argue x86 is dying, but x86 has more server-centric features than ARM, and is thus is still popular for server farms. (At least the x86 server features are more mature.)

      I wonder if GPU's will overtake both of these, or at least push x86 and ARM into being mostly coordinators. Perhaps the market will shift to specialized chip-sets for AI, databases, graphics, etc., and x86 or ARM will mostly function as process coordinators which dish out specific tasks to specialized CPUs.

      x86 turned out to be good even though it's crap, at least for high performance applications.

      People thought that RISC was the way forward for performance, because you could make simpler hardware that would allow higher clock frequencies and more parallelism. But it turned out that you could use CISC instruction sets like x86 as an intermediate language that you recompiled on the fly, optimizing for each specific CPU and even the other threads executing in parallel in a way that no compiler ever could.

      So for performance x86 is great, even if it's not really what x86 CPUs actually execute internally. For power consumption RISC is much better, as we have seen with ARM.

      Of course all this is talking generally, for specific applications the answer might differ.

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).

      I doubt AMD's lawyers are so dumb that they wouldn't license the product in such a way, that they get paid per each chip manufactured and sold. Therefore it doesn't matter what profit Hygon makes on the product. There may be issues with Hygon falsifying ledgers on the quantity of chips made, but so long as AMD actually has access to the factories, they should be able to figure out if they are getting cheated, and take their partners to court.

      AMD also if they had a good lawyer would have made sure that only certain foundries could produce the chips. As much as people say that IP laws don't work in China, they are clearly wrong. If you have a good contract, a Chinese court will find for the plaintiff. Most of the people who got screwed had crappy contracts, and didn't even get a Chinese lawyer to look over the contract and do due diligence.

      For IP that is not changing, you are correct. But so long as AMD continues to design new processors, any partners in China will continue to abide by whatever contract they have negotiated. To violate the contract would put the company at risk of losing access to future designs. This is a "goose that laid the golden egg" type scenario. If anything, the fact that they never bothered to make any changes to the CPU design is a good sign for AMD.

      It was a good move by AMD because it will guarantee them a much larger market share in China.
