Epyc CPU from eBay China without original box with manufacture stamp is a big risk.
Do you know what are different between USA Epyc and China Epyc AES instructions? China Epyc is ideal only for benchmark type of software and that is all. You do not have knowledge to even understand me. There is a big difference between benchmark type of software and enterprise cloud solutions running 24h non-stop in Data Center.
Check float point speed operations!!!
Just see this example:
“We seek to resolve the bug and still cannot. When app is deployed on the Xeon or on developers’ workstations. Everything is working as expected. When we deploy on our Epyc server all the test are passed successfully. When we deployed on China Epyc server from ebay .Net Framework get strange exceptions related to…”
I read one comment in ebay feedback. Users ask, why on the top of the cpu have blue ink? Take a look attached image. This is the answer. China MAFIA with rubber… and then print EPYC on top…
How many stupid people did buy those fiasco. I have use many hosting service. Deploy enterprise solutions. I have seen errors related to compatibility between CPU instructions and libraries from big IT providers/corporations. Theese web apps are working on Azure perfectly. Also deployed on many others clouds. Not any problems. For example, did not work on small private hosting providers with fake Epyc (HYGON). The administrators of this small private company do not realize. They do not have any clients for that reason.
HYGON is perfect for benchmark software and that is all. When you start development enterprise apps with large software stacks and infrastructures the compatibilities errors start popping. At the end you realize. Must throw this cpu in the garbage and buy a new one from official store.
Many companies have fake epyc CPUs and they do not have knowledge even to understand the problem. To test and simulated that kind of compatibility bugs, issues, etc…
Just read some comments

“They look like EPYC processors, but with different cryptography engines inside the chip.”
Chinese government spy chips confirmed!

Google Apple Facebook are spying on you right now. That have been proven but hey it’s ok to you because you’re a fucking racist. You’re trying to instigate hatred for the Chinese but you have no proof beside spreading fake infos.
ingwe - Thursday, May 30, 2019 - link
I certainly think that racism plays a significant role in international politics. But you linking a random user making a joke about the Chinese government to racism seems more than a bit tenuous. Especially your whataboutism of mentioning Google, Apple, and Facebook.
Flunk - Thursday, May 30, 2019 - link
The Chinese government does have paid shills, maybe he’s one.
SeanNing - Friday, May 31, 2019 - link
That’s funny because many of us Chinese do believe that US government has paid shills too.LOL
chrnochime - Friday, May 31, 2019 - link
I’m Asian and I think the same as he does, so you’re gonna have to use some other card other than the racist card LOL

Stop the race baiting nonsense, please. Criticism of the CCP is not racist. Only the CCP tries to claim it is.
shing3232 - Friday, May 31, 2019 - link
well, it’s not racist, more like ideological cards like Commie is bad type of stuff.

Chinese technology spying program is well known and relatively out in the open. Google Apple and Facebook are absolutely spying on me but none of them is a uniparty national government with control of nuclear weapons yet.

Yet.

Since when is an accusation against a specific government a racist comment?

Whoosh.

Honestly, it’s probably more that the Chinese doesn’t want to use cryptography primitives designed by the NSA in some nuclear missile silo or whatever (see: DUAL_EC_DRBG)
Carmen00 - Friday, May 31, 2019 - link
Ah, finally - some sense! This is the most plausible reason. The NSA has already been caught weakening crypto algorithms. Why take the risk?
ajc9988 - Friday, May 31, 2019 - link
Thank you for the common sense answer with the absurd claims made above.
Intel’s random number generator on hardware was already shown to be so simplistic and easy to crack that any cryptography based on it was insecure.
Even developing and using different cryptographic engines on different hardware globally makes the use of a single exploit on wider scales more difficult.
So tip of the hat, good sir, for bringing common sense to a non-sense point that took on a life of its own.

“while the carrier for Threadripper is orange, and for EPYC is blue, with Hygon CPUs it is red. This is very important.” LOL Probably was mandated to be red.
Lord of the Bored - Friday, May 31, 2019 - link
I laughed at that too.

According to the licensing agreement, IIRC, the Chinese version of the licensed IP cannot be sold outside of China. The color coding can help with someone trying to pull a fast one.
intr0 - Monday, June 3, 2019 - link
Dudes in Times Square already have these set out on tables for half what they cost in China.

Who is fabbing these? TSMC?

Another reason to NOT support AMD
They sell technology to enemies of the United States.
Azurael - Thursday, May 30, 2019 - link
I think the fact that the US government can use its hegemony to screw over companies it doesn’t like or sees as international rivals to its own ‘prestigious’ brands (as we’ve seen with how they’ve treated Huawei via Google et al) is a very good reason to try to find substitutes for as much US-developed/supplied technology where possible, not just Google and AMD
Tams80 - Friday, May 31, 2019 - link
Huawei have been needing a good screwing over for their overly dirty tactics (the whole business is dirty to some degree, but Huawei have taken it to a new level), so they thoroughly deserve what is happening to them now.
Azurael - Monday, June 3, 2019 - link
Well, feel free to enlighten me as to what exactly Huawei has been doing, since I’m not inclined to trust an ambiguous claim from a Five Eyes intelligence agency as an authoritative information source. How are those Cisco routers with the NSA backdoors doing?
sonny73n - Thursday, May 30, 2019 - link
To the Americans, everyone is enemy including their own. East vs West, North vs South. Not even animals live with so much hatred.
AMD CEO is Lisa Su, not Lisa Smith. Many Chinese scientists have contributed to the US. Maybe the Chinese sell AMD the Zen architecture, not the other way around.
Alistair - Thursday, May 30, 2019 - link
You’re confusing the Chinese regime (PRC) with the people. I’m sure Lisa Su dislikes the Chinese government just as much as most do.
quadibloc - Friday, May 31, 2019 - link
The Zen architecture was developed in the U.S., and AMD has the paycheques of the engineers who designed it in the U.S. to prove it. Russia invaded Georgia and the Ukraine on flimsy pretexts, because those countries rejected being run by corrupt Putin cronies and were friently with the U.S… Mainland China rules the Uighurs and the Tibetans with an iron fist; it’s run by the same Communist Party that inflicted the Great Leap Forward, the Cultural Revolution, and Tienanmen Square on the Chinese people. Considering both of those governments as menaces to any nation wanting to remain free is not a sign of irrationality on the part of the United States.
Carmen00 - Friday, May 31, 2019 - link
While you’re talking about invading countries on flimsy pretexts, would you like to bring up Iraq and Afghanistan? And perhaps the engineering of anti-democratic coups around the world and support for dictatorships, while we’re discussing oppression of people? Most of the world can legitimately consider the US to be a far bigger menace than China or Russia. China has done a heck of a lot more for my country than the US ever did. So maybe you want to get down off that high horse and stop pretending that the US stands for Freedom, or that there isn’t a very good reason to not trust US-developed technology.
But swinging this away from politics and back to technology, I think AMD’s doing the sane thing here. It’s not about east and west, it’s about brainpower and expertise. A partnership with a Chinese entity can lead to technology advances that are just as significant as those from a partnership with a US entity. The days of the US being the unchallenged world leader in technology, graciously bestowing it upon others, have been over for a long time now!
intr0 - Monday, June 3, 2019 - link
Just like Apple’s partnership with Chinese factories.
evernessince - Saturday, June 1, 2019 - link
Oh please, flimsy reasoning is America’s calling card and Trump as president is proof of that.
intr0 - Monday, June 3, 2019 - link
You’re correct. It’s a sign of irrationality on your part.

Animals just don’t feel hatred. It’s a purely human emotion.

Intel did smth similar (Atom mobile cpu related) I think. It’s just that you aren’t aware.
sgeocla - Friday, May 31, 2019 - link
Intel licensed x86 and AMD64 IP to Spreatrum to build smartphone chips in China years before AMD did the THATIC JV.
Intel fanboys are calling out AMD only because they don’t know Intel failed at that JV financially.
But the IP still got into the hands of the Chinese.
PeachNCream - Thursday, May 30, 2019 - link
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.
Lord of the Bored - Friday, May 31, 2019 - link
AMD sells processors to your mom? SCANDALOUS!
Slash3 - Friday, May 31, 2019 - link
The United States itself sells technology to enemies of the United States.
evernessince - Saturday, June 1, 2019 - link
Better boycott Intel as well, they licensed tech to the Chinese a few years back as well.
intr0 - Tuesday, June 4, 2019 - link
I had no idea they supplied the White House with tech…
extide - Thursday, May 30, 2019 - link
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.

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

Speaking of poetry… I notice the chip says that it was designed in Chengdu. That city used to have its name spelled in a lot of different ways in English. One of them was used by Samuel Taylor Coleridge.
Yes, the disco palace built with the help of the Muse Terpsichore was named after the Chinese city of Chengdu… in the movie wherein said Muse was portrayed by the lovely Olivia Newton-John.
In Xanadu did Kublai Khan a stately pleasure dome decree…
quadibloc - Friday, May 31, 2019 - link
I see I am mistaken, although there is a Xanadu hotel in Chengdu to capitalize on the confusion I apparently have shared with others. Kublai Khan built his stately palace, with a movable pleasure hut, in Shengdu, which is a city in the Chinese region of Inner Mongolia; Changdu, on the other hand, is a city in Szechwan province, which is in the southern part of China, not the northern part.
SeanNing - Friday, May 31, 2019 - link
Woa! What a surprise to meet someone interested in our culture here!
I actually am a chinese, and I’m from Inner Mongolia Autonomous Region.
The palace you mentioned is called 忽必烈夏宫, 忽必烈 is Kublai Khan，夏means summer，宫is palace. It’s also called 忽必烈行宫, which literally means Kublai Khan moving palace, but in fact, it isn’t a movable hut ,the only thing moving is Kublai Khan himself.
When summer becomes hot, emperor travels to somewhere cool and pleasing, then build a palace there and enjoy his summer time there. So “moving palace” doesn’t move, the emperor moves to the palace.
SeanNing - Friday, May 31, 2019 - link
The “Xanadu” you mentioned, is 上都, which literally means upper Capital.
During Yuan Dynasty, there were two Capital, 上都(upper Capital) and 大都(big Capital).
上都(upper Capital) is in inner mongolia, and 上都(upper Capital) is also called 夏都(summer Capital). Because Kublai Khan spends his summer here.
大都(big Capital) is Beijing.
SeanNing - Friday, May 31, 2019 - link
Anyhow, this chip is assembled in Chengdu(in Szechwan), farrrrr away from my hometown.
Hmmm, pity.
DanD85 - Friday, May 31, 2019 - link
Well, everybody need a close rival to fend off complacency. Just look at the stagnant CPU market with low cores count but high prices when Intel was dominant as an example. Without Chinese manufacturing prowess, you would have paid through the nose for your high tech toys.
evernessince - Saturday, June 1, 2019 - link
TSMC makes AMD’s chips. Most of their fabs are located outside china.

Many of the errors are pretty much easy to solve because they are labeled with an error code. But some errors show no error codes, and they are hard to solve. “An error has occurred” is one of those errors and doesn’t have any error code. In this article, office setup will discuss how to fix this issue on your PlayStation.
