Big credit to Patrick Kennedy from ServeTheHome for spotting this gem on the show floor, but it looks like if you want a Chinese branded EPYC CPU with some minor changes, it’s coming. Back in 2016, AMD and Hianjin Jaiguang Advanced Technology Investment Co. (THATIC) formed a joint venture (JV) to develop custom Zen-based processors just for the Chinese market. Within the JV, AMD would provide its Zen microarchitecture, whereas the rest of the SoC would be designed by the JV. AMD owns 49% of the company, while THATIC owns 51%. The first product out of that partnership is the Hugon Dhyana family of processors, and the first retailer with systems is Sugon.

There are lots of questions surrounding exactly what these CPUs are. A Weibo user from China has published a screenshot allegedly taken on one of Hugon Dhyana-based machines which reveals that the eight-core Dhyana 3185 features 768 KB L1 cache, 4 MB L2 cache, and 16 MB L3 cache, the same configuration as AMD’s low-end eight-core EPYC processors. They look like EPYC processors, but with different cryptography engines inside the chip. Differences beyond that are unknown, but it still uses the same packaging and the same socket as EPYC. Now with a visual image, we can tell another key significant difference – while the carrier for Threadripper is orange, and for EPYC is blue, with Hygon CPUs it is red. This is very important.

Other details about the CPU were not present – we found the CPU in a system being developed by one of the JV OEM partners. We’re working with that partner to hopefully get a system in for testing.

Interestingly enough, we got the bottom right of the CPU translated. A literal translation is 

'Using Cores to Calculate The Future'

However, the second character used in the slogan is a homonym, which could be translated as:

'Using Passion to Calculate The Future'

For a Chinese CPU, the synergestic phrasing is very poetic.

    I don't care what company sells to or works with what nation. If a company makes a product I want and sells it at a price I'm willing to pay (one that's lower than any competitors in particular) then I'm happy to buy said product. The geopolitical stuff isn't a consideration at all. Reply

    AMD sells processors to your mom? SCANDALOUS! Reply

    The United States itself sells technology to enemies of the United States. Reply

    Better boycott Intel as well, they licensed tech to the Chinese a few years back as well. Reply

    I had no idea they supplied the White House with tech... Reply

    I bet this works just like the MS/Sony deals. This is a semi-custom chip, using the Zen core, and their 3rd party encryption IP. I would imagine they want it to be fabbed in China but I don't think there are any fabs that can do small enough nodes to make this product so it would have to be GF?TSMC, and probably GF 14nm, like the regular ones.

    If watercooled, one could plumb it with Tygon! Reply

    And if it were in Ghostbusters, it'd be used by Egon! Reply

    It is, though! It's even red - a blatant tip of the hat to AMD's overlords in Beijing. Reply
