In a packed presentation kicking off this year’s Computex trade show, AMD CEO Dr. Lisa Su spent plenty of time focusing on the subject of AI. And while the bulk of that focus was on AMD’s impending client products, the company is also currently enjoying the rapid growth of their Instinct lineup of accelerators, with the MI300 continuing to break sales projections and growth records quarter after quarter. It’s no surprise then that AMD is looking to move quickly then in the AI accelerator space, both to capitalize on the market opportunities amidst the current AI mania, as well as to stay competitive with the many chipmakers large and small who are also trying to stake a claim in the space.

To that end, as part of this evening’s announcements, AMD laid out their roadmap for their Instinct product lineup for both the short and long term, with new products and new architectures in development to carry AMD through 2026 and beyond.

On the product side of matters, AMD is announcing a new Instinct accelerator, the HBM3E-equiipped MI325X. Based on the same computational silicon as the company’s MI300X accelerator, the MI325X swaps out HBM3 memory for faster and denser HBM3E, allowing AMD to produce accelerators with up to 288GB of memory, and local memory bandwidths hitting 6TB/second.

Meanwhile, AMD also showcased their first new CDNA architecture/Instinct product roadmap in two years, laying out their plans through 2026. Over the next two years AMD will be moving very quickly indeed, launching two new CDNA architectures and associated Instinct products in 2025 and 2026, respectively. The CDNA 4-powered MI350 series will be released in 2025, and that will be followed up by the even more ambitious MI400 series in 2026, which will be based on the CDNA "Next" architecture.

AMD Announces The Ryzen AI 300 Series For Mobile: Zen 5 With RDNA 3.5, and XDNA2 NPU With 50 TOPS

During AMD's opening keynote at Computex 2024, company CEO Dr. Lisa Su revealed AMD's latest AI PC-focused chip lineup for the mobile market, the Ryzen AI 300 series. Based on AMD's new Zen 5 CPU microarchitecture, the Ryzen AI 300 series – codenamed Strix Point – is intended to offer an across-the-board improvement in mobile SoC performance, with AMD proclaiming that the Ryzen AI 300 series will offer the fastest AI inference performance within the compact and portable PC market.

Under the hood, the new mobile SoC from AMD incorporates not only their new Zen 5 CPU architecture, but also their new RDNA 3.5-based integrated graphics, and the third generation XDNA2-based NPU, the latter of which is rated to deliver 50 TOPS of performance for AI-based workloads. As a result, the Ryzen AI 300 series represents a significant upgrade in AMD's mobile chip lineup, with all of the major aspects of the platform receiving a major upgrade versus their Zen 4-era Phoenix/Hawk Point SoCs. The one thing the new platform won't get, however, is a process node improvement; AMD is building Strix Point on a 4nm node, just like Phoenix/Hawk Point before it.

For this morning's announcement, AMD has unveiled the first two Ryzen AI 300 SKUs designed for notebooks. The first of these is the Ryzen AI 9 HX 370, which features 12 Zen 5 cores with a maximum boost frequency of up to 5.1 GHz, and comes equipped with 36 MB cache (12 MB L2 + 24 MB L3). The other chip to be announced is the Ryzen AI 9 365, which has two fewer Zen 5 cores (10 cores) and operates with a 5,0 GHz boost frequency and a 10 MB L2 + 24 MB L3 cache allocation.

AMD Unveils Ryzen 9000 CPUs For Desktop, Zen 5 Takes Center Stage at Computex 2024

During AMD's Computex 2024 kick-off keynote, AMD's CEO, Dr. Lisa Su, officially unveiled and announced the company's next generation of Ryzen processors. Today marks the first unveiling of AMD's highly anticipated Zen 5 microarchitecture via the Ryzen 9000 series, which is set to bring several advancements over Zen 4 and the Ryzen 7000 series for desktop PCs, which will launch sometime in July 2024.

AMD has unveiled four new chip SKUs using its Zen 5 microarchitecture. The AMD Ryzen 9 9950X processor will be the new consumer flagship part, featuring 16 CPU cores and a speedy 5.7 GHz maximum boost frequency. The other SKUs include, 6, 8, and 12 core parts, giving users a varied combination of core and thread counts. All four of these initial chips will be X-series chips, meaning they will have an unlocked multipliers and higher TDPs/clockspeeds.

In regards to performance, AMD is touting an average (geomean) IPC increase in desktop workloads for Zen 5 of 16%. And with the new desktop Ryzen chips' turbo clockspeeds remaining largely identical to their Ryzen 7000 predecessors, this should translate into similar performance expectations for the new chips.

The AMD Ryzen 9000 series will also launch on the AM5 socket, which debuted with AMD's Ryzen 7000 series and marks AMD's commitment to socket/platform longevity. Along with the Ryzen 9000 series will come a pair of new high-performance chipsets: the X870E (Extreme) and the regular X870 chipsets. The fundamental features that vendors will integrate into their specific motherboards remain tight-lipped. Still, we do know that USB 4.0 ports are standard on the X870E/X870 boards, along with PCIe 5.0 for both PCIe graphics and NVMe storage, with higher AMD EXPO memory profile support expected than previous generations.

Computex keynote season is kicking into high gear this morning with the show's leading keynote, which is being delivered by AMD. Company CEO Dr. Lisa Su will be presenting a keynote entitled “The future of high-performance computing in the AI era,” and with a run time of 90 minutes, we're expecting AMD to have a whole host of product announcements covering their full spectrum of product categories.

The big expectation here is fresh news around AMD’s Zen 5 CPU core architecture, and the chips built around it. AMD’s most recent Zen 5 roadmap has it slated to deliver all three flavors of Zen 5 by the end of this year, and we’re coming up on the two-year anniversary of the Zen 4 architecture launch.

Along with client chips, AMD has been pushing their server CPUs hard, and they’ve previously told investors that the next-gen EPYC Turin CPU is “looking great”. So we’ll likely hear about both client and server Zen 5 product plans during this keynote.

On the GPU/accelerator side of matters, AMD is mid-cycle (at best) with their Instinct MI300 series accelerators. With the company’s sales repeatedly beating their own expectations, AMD doesn’t seem to need much help moving this premium silicon right now. But with AI being the operative buzzword of this year’s Computex (and indeed, the computing industry as a whole), it would be weird for AMD to not have something to say about their rapidly growing AI accelerator product line.

Come join us at 6:30pm PT / 9:30pm ET / 01:30 UTC to get all the details.

AI Researchers Analyze Similarities of Scarlett Johanssson's Voice to OpenAI's 'Sky'

AI models can evaluate how similar voices are to each other. So NPR asked forensic voice experts at Arizona State University to compare the voice and speech patterns of OpenAI's "Sky" to Scarlett Johansson's... The researchers measured Sky, based on audio from demos OpenAI delivered last week, against the voices of around 600 professional actresses. They found that Johansson's voice is more similar to Sky than 98% of the other actresses. Yet she wasn't always the top hit in the multiple AI models that scanned the Sky voice. The researchers found that Sky was also reminiscent of other Hollywood stars, including Anne Hathaway and Keri Russell. The analysis of Sky often rated Hathaway and Russell as being even more similar to the AI than Johansson. The lab study shows that the voices of Sky and Johansson have undeniable commonalities — something many listeners believed, and that now can be supported by statistical evidence, according to Arizona State University computer scientist Visar Berisha, who led the voice analysis in the school's College of Health Solutions and the College of Engineering. "Our analysis shows that the two voices are similar but likely not identical," Berisha said... OpenAI maintains that Sky was not created with Johansson in mind, saying it was never meant to mimic the famous actress. "It's not her voice. It's not supposed to be. I'm sorry for the confusion. Clearly you think it is," Altman said at a conference this week. He said whether one voice is really similar to another will always be the subject of debate.

Male Birth Control Gel Continues to Show Promise

Gizmodo reports there's been progress on a male birth-control gel "being developed with the help of several organizations, including the U.S. government's National Institute of Child Health and Human Development, part of the larger NIH." It's now being tested in a larger-scale Phase IIB trial, which involves around 400 couples. [Five milliliters of gel — about a teaspon — is applied to each shoulder blade once a day, reports NBC News.] That trial is still ongoing, but researchers have already begun to pore through some of the available data, which has provided encouraging results. In the summer of 2022, for instance, Diana Blithe, chief of the NICHD's Contraceptive Development Program, reported that the NES/T gel's efficacy rate so far appeared to be on par or even better than contraceptive hormonal options for women... The findings are still preliminary, and it will take more time for the full Phase II data to be collected and analyzed. But Blithe and her team have been encouraged by everything they've seen to date. In the team's early assessments, the gel appears to be both effective and safe, with minimal side effects for men taking it... Blithe and her colleagues are set to meet with the FDA next year about the steps needed to begin a larger Phase III trial and are still seeking a commercial partner to help bring the NES/T gel to the market. Initial findings also showed that the contraceptive worked faster than expected, Blithe said, according to NBC News. They add that at least three other companies are also working on male birth control: Also at the Boston conference on Sunday, YourChoice Therapeutics said a very small trial in the U.K. — just 16 men — showed that its nonhormonal pill, YCT-529, was safe and free of side effects. The San Francisco company's nonhormonal pill works by blocking the vitamin A receptor important for male fertility.YourChoice is planning a larger trial, according to CEO Akash Bakshi.

8BitDo's Reimagining of IBM's Model-M Keyboard Draws Reactions Online

✇Slashdot
Par : EditorDavid

"Few computer keyboards are as iconic, as influential, or as beige as the IBM Model-M," writes the blog OMG Ubuntu adding that it's "no surprise then that it's been given a modern reimagining by 8BitDo." Following on from their Nintendo NES and Famicom and Commodore 64 homages, 8BitDo has unveiled its latest retro-inspired mechanical keyboard. This one pays tribute to a true computing classic: the IBM Model-M keyboard. Lest anyone familiar with the real thing get too excited I'll mention up front that 8BitDo's Keyboard-M is a mechanical keyboard, using Kailh Box V2 white switches (swappable, of course) and not the buckling spring mechanism synonymous with the original. On Linux you can enable a buckling spring sound effect for every key press though, should you buy this and want the clatter to accompany it...! Like 8BitDo's other retro keyboards you can use this over Bluetooth, 2.4G wireless (USB adapter sits underneath), or wired. It has a built-in rechargeable 2000mAh Li-on battery that's good for 200 hours between charges. "It certainly looks the business," writes the Verge, "especially with the slick new wireless numpad / calculator combo pad 8BitDo will sell alongside it for another $44.99." And Ars Technica adds that "The M Edition's color scheme, chunkier build, and typeface selection, including on the Tab key with arrows and elsewhere, are nods to IBM's Model M," (noting that the Model M first succeeded the Model F keyboard in 1985). "Of course, the keyboard's naming, and the IBM behemoth and floppy disks strategically placed in marketing images, are notes of that, too..." "The M Edition also comes with the detachable A and B "Super Buttons" that connect to the keyboard via a 3.5 mm jack and are programmable without software." "The paint job is pretty faithful to the original," notes Windows Central, "with a combination of gray and white throughout, right down to the accurately recreated LED status panel in the right-hand corner. There are even two key caps with an IBM-inspired blue font on them. It's just tremendous." Ars Technica offers this advice to unconvinced purists: If you want a real Model M, there's a market of found and restored models available online and in thrift stores and electronics stores. For a modern spin, like USB ports and Mac support, Unicomp also makes new Model M keyboards that are truer to the original IBM design, particularly in their use of buckling spring switches.

Amazon's Drones Gets Key Approval, Can Now Fly Farther to More Customers

The Associated Press reports that U.S. federal regulators "have given Amazon key permission that will allow it to expand its drone delivery program, the company announced Thursday." In a blog post published on its website, Seattle-based Amazon said that the Federal Aviation Administration has given its Prime Air delivery service the OK to operate drones "beyond visual line of sight," removing a barrier that has prevented its drones from traveling longer distances. With the approval, Amazon pilots can now operate drones remotely without seeing it with their own eyes. An FAA spokesperson said the approval applies to College Station, Texas, where the company launched drone deliveries in late 2022. Amazon said its planning to immediately scale its operations in that city in an effort to reach customers in more densely populated areas. It says the approval from regulators also "lays the foundation" to scale its operations to more locations around the country... Amazon, which has sought this permission for years, said it received approval from regulators after developing a strategy that ensures its drones could detect and avoid obstacles in the air. Furthermore, the company said it submitted other engineering information to the FAA and conducted flight demonstrations in front of federal inspectors. Those demonstrations were also done "in the presence of real planes, helicopters, and a hot air balloon to demonstrate how the drone safely navigated away from each of them," Amazon said. The article also points out that by the end of the decade, Amazon "has a goal of delivering 500 million packages by drone every year." To achieve this, Amazon said in its blog post, "we knew we had to design a system capable of serving highly populated areas and that was safer than driving to the store."

Ozempic-Like Drugs Could Lower Sales of Junk Food

Will appetite-suppressing drugs hurt the sugar industry? Executives from Walmart warned that Ozempic and Zepbound "are impacting food sales," reports Bloomberg, "and multiple analyst surveys have showed that less-hungry customers are spending fewer dollars at grocery stores and restaurants." The drugs, which cut cravings, will result in a decline in calorie consumption in the US of 1.5% to 2.5% by 2035, with a drop of as much as 5% in the consumption of sweets such as baked goods, confectionery and soda, Morgan Stanley analysts including Pamela Kaufman said in a report last month. Morgan Stanley forecast about a 10th of the US population will be on the so-called GLP-1 medications — originally designed to treat diabetes but being used by many as a powerful weight-loss tool — by 2035... Even with tight supplies and sky-high prices limiting uptake of the medications, sales of GLP-1 drugs for both obesity and diabetes already exceeded $19 billion in 2023. The global obesity market alone could top $100 billion by the end of the decade, Goldman Sachs Group Inc. estimates, while Bloomberg Intelligence forecasts $80 billion of sales. More than 60% of US consumers taking the drugs said they had cut back on sweet treats like candy, ice cream and baked goods, and many said they had either significantly — or entirely — stopped eating those products, according to Morgan Stanley.

Is the New 'Recall' Feature in Windows a Security and Privacy Nightmare?

✇Slashdot
Par : EditorDavid
2 juin 2024 à 19:03
Slashdot reader storagedude shares a provocative post from the cybersecurity news blog of Cyble Inc. (a Ycombinator-backed company promising "AI-powered actionable threat intelligence"). The post delves into concerns that the new "Recall" feature planned for Windows (on upcoming Copilot+ PCs) is "a security and privacy nightmare." Copilot Recall will be enabled by default and will capture frequent screenshots, or "snapshots," of a user's activity and store them in a local database tied to the user account. The potential for exposure of personal and sensitive data through the new feature has alarmed security and privacy advocates and even sparked a UK inquiry into the issue. In a long Mastodon thread on the new feature, Windows security researcher Kevin Beaumont wrote, "I'm not being hyperbolic when I say this is the dumbest cybersecurity move in a decade. Good luck to my parents safely using their PC." In a blog post on Recall security and privacy, Microsoft said that processing and storage are done only on the local device and encrypted, but even Microsoft's own explanations raise concerns: "Note that Recall does not perform content moderation. It will not hide information such as passwords or financial account numbers. That data may be in snapshots that are stored on your device, especially when sites do not follow standard internet protocols like cloaking password entry." Security and privacy advocates take issue with assertions that the data is stored securely on the local device. If someone has a user's password or if a court orders that data be turned over for legal or law enforcement purposes, the amount of data exposed could be much greater with Recall than would otherwise be exposed... And hackers, malware and infostealers will have access to vastly more data than they would without Recall. Beaumont said the screenshots are stored in a SQLite database, "and you can access it as the user including programmatically. It 100% does not need physical access and can be stolen.... Recall enables threat actors to automate scraping everything you've ever looked at within seconds." Beaumont's LinkedIn profile and blog say that starting in 2020 he worked at Microsoft for nearly a year as a senior threat intelligence analyst. And now Beaumont's Mastodon post is also raising other concerns (according to Cyble's blog post): "Sensitive data deleted by users will still be saved in Recall screenshots... 'If you or a friend use disappearing messages in WhatsApp, Signal etc, it is recorded regardless.'" "Beaumont also questioned Microsoft's assertion that all this is done locally." The blog post also notes that Leslie Carhart, Director of Incident Response at Dragos, had this reaction to Beaumont's post. "The outrage and disbelief are warranted."
