Arm Says Its Next-Gen Mobile GPU Will Be Its Most 'Performant and Efficient'

Par : msmash
29 mai 2024 à 15:35
IP core designer Arm announced its next-generation CPU and GPU designs for flagship smartphones: the Cortex-X925 CPU and Immortalis G925 GPU. Both are direct successors to the Cortex-X4 and Immortalis G720 that currently power MediaTek's Dimensity 9300 chip inside flagship smartphones like the Vivo X100 and X100 Pro and Oppo Find X7. From a report: Arm changed the naming convention for its Cortex-X CPU design to highlight what it says is a much faster CPU design. It claims the X925's single-core performance is 36 percent faster than the X4 (when measured in Geekbench). Arm says it increased the AI workload performance by 41 percent, time to token, with up to 3MB of private L2 cache. The Cortex-X925 brings a new generation of Cortex-A microarchitectures ("little" cores) with it, too: the Cortex-A725, which Arm says has 35 percent better performance efficiency than last-gen's A720 and a 15 percent more power-efficient Cortex-A520. Arm's new Immortalis G925 GPU is its "most performant and efficient GPU" to date, it says. It's 37 percent faster on graphics applications compared to the last-gen G720, with improved ray-tracing performance with intricate objects by 52 percent and improved AI and ML workloads by 34 percent -- all while using 30 percent less power. For the first time, Arm will offer "optimized layouts" of its new CPU and GPU designs that it says will be easier for device makers to "drop" or implement into their own system on chip (SoC) layouts. Arm says this new physical implementation solution will help other companies get their devices to market faster, which, if true, means we could see more devices with Arm Cortex-X925 and / or Immortalis G925 than the few that shipped with its last-gen ones.

Apple Announces M4 With More CPU Cores and AI Focus

An anonymous reader quotes a report from Ars Technica: In a major shake-up of its chip roadmap, Apple has announced a new M4 processor for today's iPad Pro refresh, barely six months after releasing the first MacBook Pros with the M3 and not even two months after updating the MacBook Air with the M3. Apple says the M4 includes "up to" four high-performance CPU cores, six high-efficiency cores, and a 10-core GPU. Apple's high-level performance estimates say that the M4 has 50 percent faster CPU performance and four times as much graphics performance. Like the GPU in the M3, the M4 also supports hardware-accelerated ray-tracing to enable more advanced lighting effects in games and other apps. Due partly to its "second-generation" 3 nm manufacturing process, Apple says the M4 can match the performance of the M2 while using just half the power. As with so much else in the tech industry right now, the M4 also has an AI focus; Apple says it's beefing up the 16-core Neural Engine (Apple's equivalent of the Neural Processing Unit that companies like Qualcomm, Intel, AMD, and Microsoft have been pushing lately). Apple says the M4 runs up to 38 trillion operations per second (TOPS), considerably ahead of Intel's Meteor Lake platform, though a bit short of the 45 TOPS that Qualcomm is promising with the Snapdragon X Elite and Plus series. The M3's Neural Engine is only capable of 18 TOPS, so that's a major step up for Apple's hardware. Apple's chips since 2017 have included some version of the Neural Engine, though to date, those have mostly been used to enhance and categorize photos, perform optical character recognition, enable offline dictation, and do other oddities. But it may be that Apple needs something faster for the kinds of on-device large language model-backed generative AI that it's expected to introduce in iOS and iPadOS 18 at WWDC next month. A separate report from the Wall Street Journal says Apple is developing a custom chip to run AI software in datacenters. "Apple's server chip will likely be focused on running AI models, also known as inference, rather than in training AI models, where Nvidia is dominant," reports Reuters.

Why Are Laptops Moving to Soldered RAM?

Par : EditorDavid
28 avril 2024 à 19:13
This year Dell moved to soldered RAM for its XPS 14 and 16, writes Digital Trends, which "makes it impossible to upgrade, or even repair." "This was a big change from the past, where the XPS 15 and 17 were both celebrated for their upgradability." Of course, Dell isn't the first to make the transition. In fact, they're one of the last, which is what makes the decision so much tougher to swallow. Where soldered RAM was previously limited to just MacBooks and ultrabooks, it's now affecting most high-performance laptops for gaming as well. Even the fantastic ROG Zephyrus G14 moved to soldered memory this year. After two months of research, the article's author acknowledges "there are tangible benefits to companies using soldered RAM, and all the people I spoke to while writing this agree that they outweigh the downsides, but how that applies to the end-user is a bit more complicated." If there's one thing and one thing only that soldered RAM is indisputably good for, it's saving space. [Haval Othman, a senior director of experience engineering at HP] explained the benefits, saying: "If battery life, mobility, form factor (thin and light), and power efficiency are my priority among other design choices, then my mind immediately goes to soldered RAM; because that's where soldered RAM can be beneficial and power-efficient, which will lead to longer battery life. Plus, it's going to give me more space on the motherboard, so I can design the product thinner and lighter. [...] If we want a thin product, the trade-off is soldering more of the devices onto the board." This tracks. In a laptop, there's only so much space that can be used for components, and that free space grows smaller by the year to make ultrabooks possible. They're an industrywide trend that was first popularized by Apple, and the rest of the laptop manufacturing world quickly caught on. Each year, laptops are released thinner and lighter, and that means having to squeeze the components together in new, innovative ways... Soldering the memory down onto the motherboard means that it can be attached almost anywhere within the laptop instead of being slotted into a specific part of it. It effectively makes the laptop thinner by cutting back on the space that the RAM module takes up. The space saved by soldering memory can be used for other things, such as a bigger battery.... All three companies that I spoke to stress the form factor much more than any tangible cost benefits... Stuart Gill, director of global media relations, campaigns, and corporate content [said] "Both soldered and socketed RAM designs are now quite mature. As a result, we see no impact on the manufacturing process and, therefore, the cost to the consumer." SO-DIMM chips also have "relatively limited bandwidth," according to HP's Othman, "while when you solder the memory chips onto the board, you can build it for a much wider bandwidth." But the article ends by looking to the future. "The good news is that SO-DIMM memory might eventually be replaced by the CAMM2 standard." Recently approved by JEDEC, CAMM2 is said to be significantly thinner, and it'll be available both in soldered and non-soldered variants. Using CAMM2 will allow laptops to stack up to 128GB of RAM, and the frequencies are said to be going up, too. CAMM2 can also activate dual-channel memory with just a single module.

Framework Won't Be Just a Laptop Company Anymore

Par : msmash

Today, Framework is the modular repairable laptop company. Tomorrow, it wants to be a consumer electronics company, period. From a report: That's one of the biggest reasons it just raised another $18 million in funding -- it wants to expand beyond the laptop into "additional product categories." Framework CEO Nirav Patel tells me that has always been the plan. The company originally had other viable ideas beyond laptops, too. "We chose to take on the notebook space first," he says, partly because Framework knew it could bootstrap its ambitions by catering to the PC builders and tinkerers and Linux enthusiasts left behind by big OEMs -- and partly because it wanted to go big or go home. If Framework could succeed in laptops, he thought, it would be able to build almost anything. After five years building laptops, what might Framework add to the portfolio? Patel won't say -- I only get the barest hints, no matter how many different ways I ask. He won't even say if they'll make less or more of a splash than laptops. Framework might choose an "equally difficult" category or might instead try something "a bit smaller and simpler to execute, streamlined now that we have all this infrastructure."

The Legendary Zilog Z80 CPU Is Being Discontinued After Nearly 50 Years

Par : EditorDavid
20 avril 2024 à 19:34
Long-time Slashdot reader AmiMoJo shares an article from TechSpot: Zilog is retiring the Z80 after 48 years on the market. Originally developed as a project stemming from the Intel 8080, it eventually rose to become one of the most popular and widely used 8-bit CPUs in both gaming and general computing devices. The iconic IC device, developed by Federico Faggin, will soon be phased out, and interested parties only have a few months left to place their orders before Zilog's manufacturing partner ends support for the technology... Federico Faggin, an Intel engineer, founded Zilog in 1974 after his work on the Intel 4004, the first 4-bit CPU. The Zilog Z80 was then released in July 1976, conceived as a software-compatible 'extension' and enhancement of the Intel 8080 processor. Back in 1999 Slashdot was calling Zilog's updated eZ80 "one of the fastest 8-bit CPUs available today, executing code 4 times faster than a standard Z80 operating at the same clock speed." Another headline, from 2001: Zilog To File For Chapter 11...

A New Generation Is Uncovering the Tiny Doodles Left By Engineers On Old Microchips

Par : BeauHD
16 avril 2024 à 21:20
An anonymous reader quotes a report from NPR: An owl. A sharky looking bullet. The Hindu deity Ganesh. The Yin and Yang sign. All painstakingly selected and etched onto a microchip that measures about an inch square. Each microscopic silicon doodle was the handiwork of engineers at Qualcomm Incorporated, a San Diego-based company that creates wireless technology-related products and services. The engineers slipped the drawings into Qualcomm's Q1650 data decoder with care not to disturb any of the chip's functions. They were purposeless etchings, never meant to be uncovered. These doodles, also known as silicon art, chip graffiti or chip art, and dozens others like it, are remnants of tech history -- from Silicon Valley's infancy to the early 2000s -- when innovation was rapid fire and the tech still had a very human touch. Engineers would add the sketches to their microchip designs in the techie equivalent of signing their artwork. They'd etch them on chips that may end up in your cellphone, laptop or calculator. They spent hours crafting them, even though they were frowned upon by those in the C Suite. The existence of these doodles came to light decades ago, but social media is discovering them anew. And there is now a small but determined group of online hobbyists working to keep that history alive. They are still cataloguing the miniscule drawings -- many smaller than the width of a human hair and can't be seen without a microscope. These devotees post glossy videos of themselves shucking chips like oysters to see their iridescent insides and the itsy bitsy sketches that may be hidden on them. And they are eagerly saving them from the scrap heap.

AmiMoJo writes: Huawei Technologies is building a massive semiconductor equipment research and development center in Shanghai as the Chinese tech titan continues to beef up its chip supply chain to counter a U.S. crackdown. The centre's mission includes building lithography machines, vital equipment for producing cutting-edge chips. To staff the new center, Huawei is offering salary packages worth up to twice as much as local chipmakers, industry executives and sources briefed on the matter told Nikkei Asia. The company has already hired numerous engineers who have worked with top global chip tool builders like Applied Materials, Lam Research, KLA and ASML, they said, adding that chip industry veterans with more than 15 years of experience at leading chipmakers like TSMC, Intel and Micron are also among recent and potential hires. The report says Huawei is investing about 12 billion yuan ($1.66 billion) for this R&D chip plant, making it one of Shanghai's top projects for 2024. Working for the company is no easy task, says one chip engineering: "Working with them is brutal. It's not 996 -- meaning working from 9 a.m. to 9 p.m., six days a week. ... It will literally be 007 -- from midnight to midnight, seven days a week. No days off at all. The contract will be for three years, [but] the majority of people can't survive till renewal."

L’iPad est-il enfin devenu un ordinateur comme un autre ?

Par : InkS
25 mars 2024 à 11:00
Depuis quelques années, la communication d’Apple est de plus en plus insistante : l’iPad serait, promis juré, tout à fait capable de faire office d’ordinateur au sens large pour l’utilisateur lambda. L’assertion est contestable et contestée depuis qu’elle a été avancée pour la première fois. Mais alors qu’Apple devrait selon toute vraisemblance renouveler une bonne partie de sa gamme à la fin mars 2024, nous avons voulu nous reposer la question : au-delà du marketing, y a-t-il du vrai ?

La nouvelle naissance de l’impression 3D

Et si l’on pouvait fabriquer à volonté ses propres objets sans avoir à sortir d’un BTS CPRP ou s’infiltrer dans les locaux d’un industriel ? C’est la promesse que formule, depuis près de vingt ans déjà, l’impression 3D. Pourtant, pendant tout ce temps, elle n’a jamais réussi à devenir autre chose qu’un loisir de niche pratiqué par quelques passionnés (et des startups). Mais voilà que depuis 2022, de nouveaux acteurs ont entrepris de la rendre beaucoup plus abordable pour le grand public.

Quand on décide de se concevoir une nouvelle config, généralement, le système de refroidissement du CPU n’est pas un élément qu’on va mettre très haut dans la liste des postes de dépense à considérer en priorité. Pourtant, depuis quelques années, ces ventirads et AIO ont pris la sale habitude de représenter une portion de plus en plus importante de la facture totale d’une machine complète. Jusqu’à ce que de nouveaux entrants sur le marché décident que c’en était assez.

Pour Sony Interactive Entertainment, cela aura été un axe stratégique majeur, sur cette génération de console, de proposer tout un écosystème d’accessoires first party pour la PS5. Mais dans le lot, les nouveaux écouteurs sans fil Pulse Explore et le casque Pulse Elite sont tout particulièrement intrigants, parce qu’ils sont le fruit d’une collaboration très étroite avec Audeze, grand spécialiste des haut-parleurs magnétiques planaires. Tellement étroite, même, qu’elle a abouti l'été dernier à une acquisition du second par le premier.
