Testing a Chinese x86 CPU: A Deep Dive into Zen-based Hygon Dhyana Processors
by Dr. Ian Cutress & Wendell Wilson on February 27, 2020 9:00 AM ESTBenchmarks: Windows
For both systems, we installed Windows: Windows 10 Pro on the small 8-core Dhyana system, and Windows 10 Enterprise on the big dual 32-core Dhyana Plus server. With AVX/AVX2 not working properly, our range of testing was limited. As mentioned previously, some software didn’t even want to run on one system or the other, such as CPU-Z on the server.
From the numbers we can see that our 8-core Dhyana processor falls somewhere between the 6-core Ryzen 5 1600X and the 8-core Ryzen 6 1800X, due to clock speeds, but on particular tests it gets hammered by even the Athlon 200GE. The dual 32-core Dhyana Plus server seems to be in all sorts of a mess, often beaten by the Ryzen 7 1800X, or can now be easily beaten by the Ryzen 9 3950X. The one benchmark where it did really well was Corona – a memory/NUMA agnostic integer based renderer – it seems like a match made in heaven.

It seems quite clearly sarcastic to me.jospoortvliet - Monday, March 2, 2020 - link
Sarcasm doesn't translate well to online communication... sadly.Sailor23M - Thursday, February 27, 2020 - link
“ It’s amusing that this menu is called ‘Moksha Common Options’. Moksha being a word commonly associated with ‘enlightenment’ or ‘release’. This is either a clever word play, or someone digging out a non-contextual old Chinese to English dictionary in translation.“Moksha is a Sanskrit word, the oldest language in the world, its not Chinese.

"Before everyone leaps to ‘creating backdoors for the Chinese government"Yes, because apparently the first thing China demanded of AMD was the removal of PSP, a backdoor created for the American government (to spy on Americans and others).

well said.Virtually all governments are spying on people, b/c that their job to watch for bad people, whatever they see fits. If people want to complain about that, go complain to the officers who scan your body with x-ray machine in the airport.
In addition, from a tech point of view, the American government has the most advanced technology.
It is interesting to see so many people in the U.S. believe that people from other country, which is thousands of miles away, are actively planning to come and take away their sh*t, while their own government launched so many wars over the last 300 years in which they took land from the Mexicans, the Spanish, and oil from the people in the Mideast. Not to mention that the Wall street bankers and politicians in the capital hill are actively taking the American's tax money and send them to big corporations.
Talking about missing the big picture...

Great article Ian/Wendell, really informative write-up on a super interesting topic!I still can't believe that AMD was able to get the DoC, DoD, et al to sign off on this deal. And that Intel did not do a single thing to stop it. The tech may have been old, and AMD may have obfuscated its IP as much as possible, but still...as you Ian/Wendell said, one of the oddest annals of the history of semis.

I mentioned earlier that elites allowed it. Guess who ? The clue is Intel Israel. I believe the old Intel is dead esp with all the PC drivel going on in thr HR dept and BK firing pretext.Notmyusualid - Sunday, March 8, 2020 - link

Hopefully you enabled the C-states that show as disabled in that options photo before benchmarking, as otherwise it almost certainly wouldn't be able to boost to good levels for single-threaded or low-core-count operation (because all the cores are in C0).
