AMD Zen 5 Status Report: EPYC "Turin" Is Sampling, Silicon Looking Great

✇AnandTech
1 mai 2024 à 22:00

As part of AMD's Q1'2024 earnings announcement this week, the company is offering a brief status update on some of their future products set to launch later this year. Most important among these is an update on their Zen 5 CPU architecture, which is expected to launch for both client and server products later this year.

Highlighting their progress so far, AMD is confirming that EPYC "Turin" processors have begun sampling, and that these early runs of AMD's next-gen datacenter chips are meeting the company's expectations.

"Looking ahead, we are very excited about our next-gen Turin family of EPYC processors featuring our Zen 5 core," said Lisa Su, chief executive officer of AMD, at the conference call with analysts and investors (via SeekingAlpha). "We are widely sampling Turin, and the silicon is looking great. In the cloud, the significant performance and efficiency increases of Turin position us well to capture an even larger share of both first and third-party workloads."

Overall, it looks like AMD is on-track to solidify its position, and perhaps even increase its datacenter market share with its EPYC Turin processors. According to AMD, the company's server partners are developing a 30% larger number of designs for Turin than they did Genoa. This underscores how AMD's partners are preparing for even more market share growth on the back of AMD's ongoing success, not to mention the improved performance and power efficiency that the Zen 5 architecture should offer.

"In addition, there are 30% more Turin platforms in development from our server partners, compared to 4th Generation EPYC platforms, increasing our enterprise and with new solutions optimized for additional workloads," Su said. "Turin remains on track to launch later this year."

AMD's EPYC 'Turin' processors will be drop-in compatible with existing SP5 platforms (i.e., will come in an LGA 6096 package), which will facilitate its faster ramp and adoption of the platform both by cloud giants and server makers. In addition, AMD's next-generation EPYC CPUs are expected to feature more than 96 cores and a more versatile memory subsystem.

An anonymous reader quotes a report from Bloomberg: Dropbox said its digital-signature product, Dropbox Sign, was breached by hackers, who accessed user information including emails, user names and phone numbers. The software company said it became aware of the cyberattack on April 24, sought to limit the incident and reported it to law enforcement and regulatory authorities. "We discovered that the threat actor had accessed data related to all users of Dropbox Sign, such as emails and user names, in addition to general account settings," Dropbox said Wednesday in a regulatory filing. "For subsets of users, the threat actor also accessed phone numbers, hashed passwords, and certain authentication information such as API keys, OAuth tokens, and multi-factor authentication." Dropbox said there is no evidence hackers obtained user accounts or payment information. The company said it appears the attack was limited to Dropbox Sign and no other products were breached. The company didn't disclose how many customers were affected by the hack. The hack is unlikely to have a material impact on the company's finances, Dropbox said in the filing. The shares declined about 2.5% in extended trading after the cyberattack was disclosed and have fallen 20% this year through the close.

The National Archives and Records Administration (NARA) told employees Wednesday that it is blocking access to ChatGPT on agency-issued laptops to "protect our data from security threats associated with use of ChatGPT," 404 Media reported Wednesday. From the report: "NARA will block access to commercial ChatGPT on NARANet [an internal network] and on NARA issued laptops, tablets, desktop computers, and mobile phones beginning May 6, 2024," an email sent to all employees, and seen by 404 Media, reads. "NARA is taking this action to protect our data from security threats associated with use of ChatGPT." The move is particularly notable considering that this directive is coming from, well, the National Archives, whose job is to keep an accurate historical record. The email explaining the ban says the agency is particularly concerned with internal government data being incorporated into ChatGPT and leaking through its services. "ChatGPT, in particular, actively incorporates information that is input by its users in other responses, with no limitations. Like other federal agencies, NARA has determined that ChatGPT's unrestricted approach to reusing input data poses an unacceptable risk to NARA data security," the email reads. The email goes on to explain that "If sensitive, non-public NARA data is entered into ChatGPT, our data will become part of the living data set without the ability to have it removed or purged."

An anonymous reader shares a report: Two months after hackers broke into Change Healthcare systems stealing and then encrypting company data, it's still unclear how many Americans were impacted by the cyberattack. Last month, Andrew Witty, the CEO of Change Healthcare's parent company UnitedHealth Group, said that the stolen files include the personal health information of "a substantial proportion of people in America." On Wednesday, during a House hearing, when Witty was pushed to give a more definitive answer, testifying that the breach impacted "I think, maybe a third [of Americans] or somewhere of that level."

Tens of Millions Secretly Use WhatsApp Despite Bans, Company Says

"Tens of millions" of people are using technical workarounds to secretly access WhatsApp in countries where it is banned, the messaging platform's boss has said. From a report: "You'd be surprised how many people have figured it out," Will Cathcart told BBC News. Like many Western apps, WhatsApp is banned in Iran and North Korea and, intermittently, in Syria. And last month, China joined the list of those banning users from accessing the secure platform. Other countries, including Qatar, Egypt, Jordan and the United Arab Emirates, restrict features such as voice calls. But WhatsApp can see where its users truly are, thanks to their registered phone numbers. "We have a lot of anecdotal reports of people using WhatsApp and what we can do is look at some of the countries where we're seeing blocking and still see tens of millions of people connecting to WhatsApp," Mr Cathcart told BBC News. China ordered Apple to block Chinese iPhone users from downloading WhatsApp from the AppStore in April, a move Mr Cathcart calls "unfortunate" -- although the country was never a major market for the app. "That's a choice Apple has made," he said. "There aren't alternatives. I mean, that is really a situation where they've put themselves in the position to be able to truly stop something."

ArsTechnica: Sixty years ago, on May 1, 1964, at 4 am in the morning, a quiet revolution in computing began at Dartmouth College. That's when mathematicians John G. Kemeny and Thomas E. Kurtz successfully ran the first program written in their newly developed BASIC (Beginner's All-Purpose Symbolic Instruction Code) programming language on the college's General Electric GE-225 mainframe. Little did they know that their creation would go on to democratize computing and inspire generations of programmers over the next six decades.

Google Urges US To Update Immigration Rules To Attract More AI Talent

The US could lose out on valuable AI and tech talent if some of its immigration policies are not modernized, Google says in a letter sent to the Department of Labor. From a report: Google says policies like Schedule A, a list of occupations the government "pre-certified" as not having enough American workers, have to be more flexible and move faster to meet demand in technologies like AI and cybersecurity. The company says the government must update Schedule A to include AI and cybersecurity and do so more regularly. "There's wide recognition that there is a global shortage of talent in AI, but the fact remains that the US is one of the harder places to bring talent from abroad, and we risk losing out on some of the most highly sought-after people in the world," Karan Bhatia, head of government affairs and public policy at Google, tells The Verge. He noted that the occupations in Schedule A have not been updated in 20 years. Companies can apply for permanent residencies, colloquially known as green cards, for employees. The Department of Labor requires companies to get a permanent labor certification (PERM) proving there is a shortage of workers in that role. That process may take time, so the government "pre-certified" some jobs through Schedule A. The US Citizenship and Immigration Services lists Schedule A occupations as physical therapists, professional nurses, or "immigrants of exceptional ability in the sciences or arts." While the wait time for a green card isn't reduced, Google says Schedule A cuts down the processing time by about a year.

Windows 11's market share dropped in April 2024, falling below 26% after reaching an all-time high of 28.16% in February. According to Statcounter, Windows 11 lost 0.97 points, while Windows 10 gained 0.96 points, crossing the 70% mark for the first time since September 2023. Neowin adds: Some argue that Windows 11 still offers little to no benefits for upgrading, especially in light of Microsoft killing some of the system's unique features, such as Windows Subsystem for Android. Add to that the ever-increasing number of ads, some of which are quite shameless, and you get an operating system that has a hard time winning hearts and minds, and retaining its customers.

Microsoft Concern Over Google's Lead Drove OpenAI Investment

Microsoft's motivation for investing heavily and partnering with OpenAI came from a sense of falling badly behind Google, according to an internal email released Tuesday as part of the Justice Department's antitrust case against the search giant. Bloomberg: The Windows software maker's chief technology officer, Kevin Scott, was "very, very worried" when he looked at the AI model-training capability gap between Alphabet's efforts and Microsoft's, he wrote in a 2019 message to Chief Executive Officer Satya Nadella and co-founder Bill Gates. The exchange shows how the company's top executives privately acknowledged they lacked the infrastructure and development speed to catch up to the likes of OpenAI and Google's DeepMind. [...] Scott, who also serves as executive vice president of artificial intelligence at Microsoft, observed that Google's search product had improved on competitive metrics because of the Alphabet company's advancements in AI. The Microsoft executive wrote that he made a mistake by dismissing some of the earlier AI efforts of its competitors. "We are multiple years behind the competition in terms of machine learning scale," Scott said in the email. Significant portions of the message, titled 'Thoughts on OpenAI,' remain redacted. Nadella endorsed Scott's email, forwarding it to Chief Financial Officer Amy Hood and saying it explains "why I want us to do this."

Global Debt Hasn't Been This Bad Since the Napoleonic Wars, Says WEF President

The massive volumes of debt piling up around the globe forced the president of the World Economic Forum to reach back more than 200 years for a comparable period. Fortune: In an interview Sunday with CNBC at a WEF conference in Saudi Arabia, Borge Brende warned overall debt is approaching the world's total economic output. "We haven't seen this kind of debt since the Napoleonic Wars," he said. "We're getting close to 100% of global GDP in debt." According to the International Monetary Fund last year, global public debt hit $91 trillion, or 92% of GDP, by the end of 2022. That was actually a dip from pandemic-era debt levels but remained in line with a decades-long trend higher. Data on global debt during the Napoleonic Wars, which took place in the early 1800s, is harder to come by. But for comparison, some estimates put British government debt at more than 200% of GDP by 1815. Brende also told CNBC that governments need to take fiscal measures to reduce their debts without triggering a recession. For now, global growth is about 3.2% annually, which isn't bad, but it's also below the 4% trend growth the world had seen for decades, he said earlier in the interview. That risks a repeat of the 1970s, when growth was low for a decade, Brende added. But the world can avoid such an outcome if it continues to trade and doesn't engage in more trade wars. "Trade was the engine of growth for decades," he said.

Firebat A8 : un MiniPC Ryzen 7 8845HS qui sort du lot

✇MiniMachines.net

Minimachines.net en partenariat avec TopAchat.com

Le Firebat A8 ne ressemble pas aux précédents modèles de cette marque. Toutes les machines commercialisées par le passé étaient des clones purs et simples des MiniPC classiques. Ce modèle change de formule.

Avec l’affaire des virus qui a touché ces fabricants qui reprenaient tous les mêmes designs, les marques veulent se sortir de cette impasse marketing. Il est devenu important de se démarquer, de proposer un design alternatif. Différent de ce que mettent en avant d’autres constructeurs. Histoire qu’on ne confonde pas « leur » machine avec celle des autres. 

Ce Firebat T8 change donc de format même si je suis quasiment sûr que nous retrouveront des machines totalement identique. Un signe qui ne trompe pas avec ces MiniPC en général c’est la connectique employée. Si la coque change avec ici une partie supérieure découpée de grille en forme de croix. Les ports des différents connecteurs devraient se retrouver chez d’autres constructeurs. Firebat étant une de ces marque sans usine s’appuyant sur un constructeur différent pour produire ses machines il a simplement du commander un boitier différent pour se protéger.

Le châssis mesure 14.8 cm de large pour 12.7 cm de profondeur et 5 bons cm d’épaisseur. A l’intérieur on retrouve un Ryzen 7 8845HS et ses 8 cœurs AMD Zen 4 accompagnés des 12 cœurs RDNA3 de son circuit graphique Radeon 780M. Un petit NPU Ryzen AI est également de la partie et délivre 16 TOPS de performances. L’engin propose deux ports SODIMM double canal de DDR5-5600 et un port M.2 2280 NVM PCIe 4.0… Pas de mention d’un espace de stockage 3.5″ supplémentaire malgré l’épaisseur de l’engin. A la place un système comprenant pas moins de trois caloducs pour gérer la chaleur de l’engin avec un ventilateur processeur et un second au niveau des composants mémoire et stockage.

On retrouve un module Wi-Fi6 et Bluetooth 5.2 classique et en façade deux USB 3.2 Type-A, un USB4, un jack audio combo 3.5 mm et un lecteur de cartes MicroSDXC. A noter que le système pourra démarrer sur ce lecteur et donc sera potentiellement apte a piloter des systèmes alternatifs à son  Windows 11 installé par défaut.

A l’arrière on retrouve 4 ports USB Type-A séparés en paires USB 2.0 et USB 3.2. Deux sorties vidéo en HDMI 2.1 et DisplayPort 1.4, deux port Ethernet 2.5 Gigabit, un second jack audio combo 3.5 mm et un autre port USB4. Un port Antivol type Kensington Lock est également visible ainsi qu’une alimentation Jack. Le boitier est compatible VESA et ouvert largement sur les côtés comme sur l’arrière.

Un ensemble très complet pour le moment vendu à plus de 600€ sur AliExpress sans possibilité de livraison vers la France dans une version 16 Go / 1 To. Un élément qui signifie en général que l’engin est toujours en cours de production et non pas en stock. Le prix devrait baisser au moment de la disponibilité de la machine avec plus de possibilités de se faire livrer et, peut être, plus d’infos sur les entrailles de l’engin.
