AMD Slims Down Compute With Radeon Pro W7900 Dual Slot For AI Inference

3 juin 2024 à 03:05

While the bulk of AMD’s Computex presentation was on CPUs and their Instinct lineup of dedicated AI accelerators, the company also has a small product refresh for the professional graphics and workstation AI crowd. AMD is releasing a dual-slot version of their high-end Radeon Pro W7900 card – aptly named the W7900 Dual Slot – with the intent being to improve compute density in workstations by making it possible to install 4 of the cards inside a single chassis.

The release of a dual-slot version of the card comes after the original Radeon Pro W7900 was the first time AMD went with a larger, triple-slot form factor for their flagship workstation card. With the W7000 generation bringing an all-around increase in power consumption, pushing the W7900 to 295 Watts, AMD originally opted to release a larger card for improved acoustics. However this came at the cost of compute density, as most systems could only fit 2 of the thicker cards. As a result, AMD is opting to release a dual-slot version of the hardware as well, to offer a more competitive product for high-density workstation systems – particularly those doing local AI inference.

Other than the narrower cooler, the Radeon Pro W7900DS is for all intents and purposes identical to the original W7900, with the same Navi 31 GPU being driven to the same clockspeeds, and the overall board being run to the same 295 Total Board Power (TBP) limit. This is paired with the same 18Gbps GDDR6 as before, giving the card 48GB of VRAM.

Officially, AMD doesn’t have a noise specification for these cards. But you can expect that the W7900DS will be louder than its triple-slot senior. By all appearances, AMD is just using the cooler from the W7800, which was a dual-slot card from the start, so that cooler is being tasked with handling another 35W of heat dissipation.

As the W7800 was also AMD’s fastest dual-slot card up until now, it’s an apt point of comparison for compute density. With its full-fat Navi 31 GPU, the W7900DS will offer about 36% more compute/pixel throughput than its sibling/predecessor. So it’s a not-insubstantial improvement for the very specific niche AMD has in mind for the card.

And like so many other things being announced at Computex this year, that niche is AI. While AMD offers PCIe versions of their Instinct MI210 accelerators, those cards are geared at servers, with fully-passive coolers to match. So workstation-level compute is largely picked up by AMD’s Radeon Pro workstation cards, which are intended to go into a traditional PC chassis and use active cooling (blowers). In this case, AMD is specifically going after local inference workloads, as that’s what the Radeon hardware and its significant VRAM pool are best suited for.

The Radeon Pro W7900 Dual Slot will drop on June 19th. Notably, AMD is introducing the card at a slightly lower price tag than they launched the original W7900 at last year, with the W7900DS hitting retail shelves at $3499, down from the W7900’s original $3999 price tag.

ROCm 6.1 For Radeons Coming as Well

Alongside the release of the W7900DS, AMD is also promoting the upcoming Radeon release of ROCm 6.1, their software stack for GPU computing. While baseline ROCm 6.1 was introduced back in April, the Windows version of AMD’s software stack is still a trailing (and feature limited) release. So that is slated to finally get bumped up to a ROCm 6.1 release on June 19th, the same day the W7900DS launches.

ROCm 6.1 for Radeons is slated to bring a couple of major changes/improvements to the stack, particularly when it comes to expanding the scope of available features. Notably, AMD will finally be shipping Windows Subsystem for Linux 2 (WSL2) support, albeit at a beta level, allowing Windows users to access the much richer feature set and software ecosystem of ROCm under Linux. This release will also incorporate improved support for multi-GPU configurations, perfect timing for the launch of the Radeon Pro W7900DS.

Finally, ROCm 6.1 sees TensorFlow integrated into the ROCm software stack as a first-class citizen. While this matter involves more complexities than can be summarized in a simple news story, native TensorFlow support under Windows was previously blocked by a lack of a Windows version of AMD’s MIOpen machine learning library. Combined with WSL2 support, developers will have two ways to access TensorFlow on Windows systems going forward.

AMD Launching New CPUs for AM4: Ryzen 5000XT Series Coming in July

3 juin 2024 à 03:04

During their opening keynote at Computex 2024, AMD announced their intention to launch a pair of new Ryzen 5000 processors for their legacy AM4 platform. The new chips, both getting the XT suffix, will be the Ryzen 9 5900XT, a 16 core Zen 3 part, while the Ryzen 7 5800XT will be an 8 core Zen 3.

The new chips are intended to underscore AMD's ongoing commitment to supporting their consumer platforms over several years. And while the specification changes are rather minor overall – the Zen 3 CPU architecture has long since been taken as far as it can reasonable go – it does give AMD a chance to refresh the platform by slinging hardware at new price points. AMD did something very similar for the Ryzen 3000 generation with the late-model Ryzen 3000 XT chips.

Ryzen 7 5800X 8C / 16T 3.8 GHz 4.7 GHz 4 MB 32 MB 105 W

We've dedicated many column inches covering Zen 3 and the Ryzen 5000 series since they launched in late 2020, so there isn't anything new to add here. Zen 3 is no longer AMD's latest and greatest, but the platform as a whole is quite cheap to produce, making it a viable budget offering for new builds, or offering one last upgrade for old builds.

The Ryzen 9 5900XT is a 16 core part, and isn't to be confused with the Ryzen 9 5900X, which is a 12 core part. It ships with a peak turbo clockspeed of 4.8GHz, 100 MHz lower than the top-tier Ryzen 9 5950X. This makes it's XT designation somewhat of a misnomer compared to previous generations of XT chips, although it's clear that AMD has boxed themselves into a corner with their naming scheme, as they both need a way to designate that this is a new chip, and yet still place it below the 5950X.

Looking at the second chip, we have the Ryzen 7 5800XT. This is an 8 core part that does improve on its predecessor, offering a 4.8GHz max turbo clock that is 100MHz higher than the Ryzen 7 5800X's. Both chips otherwise share the same characteristics, including 6 MB of L2 cache and 32 MB of L3 cache, and all four of the chips – including the two new XT series and the corresponding X series chips – all come with a 105 Watt TDP.

In terms of motherboard compatibility, all of the AM4 motherboards that currently support the Ryzen 5000 series are also compatible with the Ryzen 5000XT series, although users are likely to need to perform a firmware update to ensure maximum compatibility; they are the same chips, but the microcodes are likely different.

AMD has provided some gaming performance figures comparing the Ryzen 9 5900XT to Intel's 13th Gen Core i7-13700K. It does offer very modest yet marginal gains in games by up to 4%; it's not mind-blowing, but the price could be the decisive factor here.

Regarding price, AMD hasn't disclosed anything official yet ahead of the expected launch of the Ryzen 5000XT series chips in July. It's hard to make a case for a pair of chips to be considered a fully-fledged series, but it does open up the doors for AMD to perhaps launch more 5000XT series chips in the future.

Law Student Claims Unfair Discipline After He Reported a Data Breach

3 juin 2024 à 03:36
An anonymous Slashdot reader shared this report from Computer Weekly: A former student at the Inns of Court College of Advocacy (ICCA) says he was hauled over the coals by the college for having acted responsibly and "with integrity" in reporting a security blunder that left sensitive information about students exposed. Bartek Wytrzyszczewski faced misconduct proceedings after alerting the college to a data breach exposing sensitive information on hundreds of past and present ICCA students... The ICCA, which offers training to future barristers, informed data protection regulator the Information Commissioner's Office of a breach "experienced" in August 2023 after Wytrzyszczewski alerted the college that sensitive files on nearly 800 students were accessible to other college users via the ICCA's web portal. The breach saw personal data such as email addresses, phone numbers and academic information — including exam marks and previous institutions attended — accessible to students at the college. Students using the ICCA's web portal were also able to access ID photos, as well as student ID numbers and sensitive data, such as health records, visa status and information as to whether they were pregnant or had children... After the college secured a written undertaking from Wytrzyszczewski not to disclose any of the information he had discovered, it launched misconduct proceedings against him. He had stumbled across the files in error, he said, and viewed a significant number to ensure he could report their contents with accuracy. "The panel cleared Wytrzyszczewski and found it had no jurisdiction to hear the matter," according to the article. But he "said the experience caused him to unenroll from the ICCA's course and restart his training at another provider."

AMD Plans Massive Memory Instinct MI325X for Q4'24, Lays Out Accelerator Roadmap to 2026

3 juin 2024 à 03:02

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

3 juin 2024 à 03:01

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

3 juin 2024 à 03:00

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.

The AMD Computex 2024 Keynote Live Blog (6:30pm PT/01:30 UTC)

3 juin 2024 à 01:00

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'

Par : EditorDavid
3 juin 2024 à 01:34
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

Par : EditorDavid
2 juin 2024 à 23:38
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.
