AMD Zen-based Hygon chips start putting the squeez

A rare Chinese branded EPYC CPU clone has been spotted on the show floor of Computex 2019. This Hugon Dhyana processor is near enough the same as its first-generation EPYC counterpart, reportedly warranting very few changes to the code, however, it has been tweaked by AMD and its partners ever so slightly to better suit the burgeoning datacentre market in China.

A couple years ago AMD formed a joint venture with various Chinese investors to produce the Tianjin Haiguang Advanced Technology Investment Co. (THATIC), a company devoted to piecing together genuine x86 processors within China. These processors go by the name Hugon Dhyana, and branded under Hygon. Both EPYC and Ryzen lookalikes have been spotted rocking the rebrand.

But pushing genuine x86 processors into the chinese market is no easy feat, nor is bypassing the airtight x86 licensing agreement that AMD must abide by otherwise face the wrath of Intel. In order to do so, the red team and its partners have weaved together a network of subsidiaries, joint ventures, and agreements in order to avoid any litigious actions.

AMD-owned HMC handling production of Hugon Dhyana processors, while THATIC-owned Hygon designs them. The final products can only be sold within China, however, and until now, have remained elusive.

But all that manoeuvring has finally resulted in the Hygon EPYC chip first spotted over at Computex by Servethehome (via AnandTech).

These chips are reportedly similar in form and function to their EPYC counterparts, the cryptography engine reportedly the only major discernible difference. The server-grade processors utilise the exact same TR4 socket as their AMD progenitors too, while the few glimpses of smaller, desktop chips indicate an AM4-sized design and soldered BGA connection.
