NVIDIA GeForce RTX 3080 Tested: a Huge Leap Forward In Gaming Performance (hothardware.com) 43

MojoKid writes: NVIDIA CEO Jensen Huang officially unveiled the GeForce RTX 30 series based on the company's new Ampere architecture a couple of weeks back. According to Huang, the GeForce RTX 30 series represents the greatest generational leap in the company's history and he claimed the GeForce RTX 3080 would offer double the performance of its predecessor. The embargo for GeForce RTX 3080 reviews just lifted and it seems NVIDIA was intent on making good on its claims. The GeForce RTX 3080 is the fastest GPU released to date, across the board, regardless of the game, application, or benchmarks used. Throughout testing, the GeForce RTX 3080 often put up scores more than doubling the performance of AMD's current flagship Radeon RX 5700 XT. The RTX 3080 even skunked the NVIDIA Titan RTX and GeForce RTX 2080 Ti by relatively large margins, even though it will retail for almost half the price of a 2080 Ti (at least currently). The bottom line is, NVIDIA's got an absolutely stellar-performing GPU on its hands, and the GeForce RTX 3080 isn't even the best Ampere has to offer, with the RTX 3090 waiting in the wings. GeForce RTX 3080 cards will be available from NVIDIA and third-party board partners on 9/17 for an entry-level MSRP of $699.

USB-C Was Supposed To Simplify Our Lives. Instead, It's a Total Mess. (medium.com) 155

USB-C is near-ubiquitous: Almost every modern laptop and smartphone has at least one USB-C port, with the exception of the iPhone, which still uses Apple's proprietary Lightning port. For all its improvements, USB-C has become a mess of tangled standards -- a nightmare for consumers to navigate despite the initial promise of simplicity. From a report: Anyone going all-in on USB-C will run into problems with an optional standard called Power Delivery. The standard allows devices to charge at a much higher wattage relative to older connectors, therefore allowing them to charge faster. But it requires the right combination of charger, cables, and device to actually achieve this. If you buy a USB-C charger that doesn't support Power Delivery and try to use it with a Microsoft Surface, for example, the laptop will complain that it's "not charging" despite receiving some power. Fixing this requires figuring out whether or not it's the cable or wall charger that doesn't support Power Delivery, and replacing it with something that does support it. There would be no way for a layperson to hold two USB-C chargers and know the difference between one that supports Power Delivery and one that doesn't.

Furthering the confusion, some devices actually can't be charged with chargers supporting Power Delivery, despite sporting a USB-C port -- because they weren't designed to negotiate the higher wattage being delivered by the Power Delivery standard. A pair of cheap Anker headphones I own, for example, refuse to charge when plugged into a MacBook charger. Other devices, like the Nintendo Switch, only partially support the standard, and some unsupported chargers have bricked devices, reportedly due to the Switch's maximum voltage being exceeded. Then there's DisplayPort and Thunderbolt, another set of standards supported by some USB-C devices. DisplayPort allows the use of an external display, such as a 4K monitor, but only supports one at a time at full resolution. Thunderbolt, yet another optional standard, is a much faster layer on top of USB-C that allows additional possibilities, like the use of multiple displays daisy-chained from a single port, or the use of an external graphics card. It uses the exact same connector, but can be identified with an additional "lightning" symbol when supported.

Apple Introduces Redesigned iPad Air With A14 Chip, All-Screen Design, TouchID and USB-C (macrumors.com) 64

Apple today introduced a redesigned iPad Air that looks more like an iPad Pro, as well as an updated 8th-generation, entry-level iPad. MacRumors reports on the new iPad Air: Apple today introduced a redesigned iPad Air with slimmer bezels, paving the way for an all-screen design similar to recent iPad Pro models. In addition, the new iPad Air is the first Apple device with Touch ID built into the power button. The new iPad Air is powered by the new 5nm-based, six-core A14 Bionic chip for up to 40 percent faster performance and up to 30 percent faster graphics than the previous-generation iPad Air.

The device features a fully laminated 10.9-inch Liquid Retina display with True Tone, P3 wide color support, and an anti-reflective coating. Following in the footsteps of the iPad Pro, the new iPad Air features a USB-C port instead of a Lightning connector. The device also features the same 12-megapixel rear camera used in the iPad Pro for higher-resolution photos and 4K video recording. The new iPad Air will be available starting in October on Apple.com and the Apple Store app in 30 countries and regions. Wi-Fi models will start at $599, while cellular models will start at $729, with 64GB and 256GB storage capacities available. There will be five colors to choose from, including silver, space gray, rose gold, green, and sky blue.
9to5Mac reports on the 8th-generation iPad: Apple today announced the 8th-generation iPad, featuring an A12 chip compared to the previous-generation's A10 processor. The design of the new entry-level iPad is largely the same as its predecessor. The jump from A10 to A12 means Apple's cheapest iPad will feature the Neural Engine for the first time. Apple says the A12 chip offers more than twice the performance of the top selling Windows laptop, 6x faster than the top-selling Android tablet and 6x faster than the best-selling Chromebook. The 8th-generation iPad keeps the same price as the 7th-gen: that's $329 for general sale and $299 for education.

The Gateway PC Brand Returns With New Laptops (pcmag.com) 55

On Wednesday, Acer and Walmart announced they were reviving the Gateway brand to sell affordable Windows 10 notebooks and laptop convertibles from $179 and up. PCMag reports: Gateway was once a major PC vendor in the US, especially during the 1990s when it famously sold computers packaged in cow spotted boxes. However, the company's fortunes began to falter in the 2000s, resulting in Taiwanese PC vendor Acer later buying it up. Acer has now decided to bring back Gateway, calling it a "beloved" brand in the US. And to market the products, the company has resurrected the cow spotted box logo.

According to Acer, the products are designed for everyday consumers, students and "creators," who pump out content or graphic designs. The hardware will also feature processors from either Intel or AMD, and come fitted with 1080p screens. In total, the Gateway PCs span nine different notebook models. At the low-end is the "11.6-inch Ultra Slim" laptop, which retails for $179, and contains 4GB of RAM and 64GB of storage. At the high-end, you can buy the "Gateway Creator Series 15.6-inch Performance Notebook," which has an Intel 10th Gen Core i5-10300H processor, an NVIDIA 2060 RTX graphics card, 256GB of SSD storage and 8GB of RAM.

Ten Years Ago, Epic Helped To Legitimize iOS as a Gaming Platform With a Small Demo (theverge.com) 46

An anonymous reader shares a report: On September 1st, 2010, Epic Games released its Citadel tech demo in the Apple App Store. It was a boring thing to actually play -- you simply walked around a medieval town in first-person perspective, taking in the sights with no objectives -- but this calm debut marked a big moment for iOS, the App Store, and Epic Games. It proved that developers could fit gigantic, richly detailed set pieces running on a smartphone and do it while utilizing Unreal Engine 3, the same engine that powered some of the most popular games in the Xbox 360 and PS3 era of consoles. The devices of choice, if you wanted to get access to mobile games with impressive graphics, were suddenly just the iPhone, iPad, and iPod touch. The Citadel demo didn't come to Android until almost two and a half years later in 2013.

The Citadel demo was groundbreaking at the time, and it possibly helped to kickstart the trend of bringing console-like experiences to the nascent mobile gaming platform. When I first saw it, I remember feeling like I immediately needed to throw my HTC Droid Eris out the window and buy an iPhone instead. I eventually got to try it out on an iPad at the gadget store where I was employed at the time, and it was stunning to see high-fidelity textures that had dimension and lighting that dynamically shifted when you walked into a building. There were even reflections at a certain point. I had played better-looking games on PC at that point, but something about the experience of being packed into a tiny device made for a magical proof of concept that left an impact on me, even as the fun of walking around Citadel lost its appeal. Ten years later, things are very different. Right now, Epic Games and Apple are in the midst of a high-profile legal battle that will likely have a serious impact on their relationship moving forward.

Lenovo Releases First Fedora Linux ThinkPad Laptop (zdnet.com) 80

Today, Lenovo has released a ThinkPad with Red Hat's community Linux, Fedora. ZDNet reports: First in this new Linux-friendly lineup is the X1 Carbon Gen 8. It will be followed by forthcoming versions of the ThinkPad P1 Gen2 and ThinkPad P53. While ThinkPads are usually meant for business users, Lenovo will be happy to sell the Fedora-powered X1 Carbon to home users as well. The new X1 Carbon runs Fedora Workstation 32. This cutting-edge Linux distribution uses the Linux Kernel 5.6. It includes WireGuard virtual private network (VPN) support and USB4 support. This Fedora version uses the new GNOME 3.36 for its default desktop.

The system itself comes standard with a 10th Generation Intel Core 1.6Ghz i5-10210U CPU, with up to 4.20 GHz with Turbo Boost. This processor boasts 4 Cores, 8 Threads, and a 6 MB cache. It also comes with 8MBs of LPDDR3 RAM. Unfortunately, its memory is soldered in. While that reduces the manufacturing costs, Linux users tend to like to optimize their hardware and this restricts their ability to add RAM. You can upgrade it to 16MBs, of course, when you buy it for an additional $149. For storage, the X1 defaults to a 256GB SSD. You can push it up to a 1TB SSD. That upgrade will cost you $536.

The X1 Carbon Gen 8 has a 14.0" Full High Definition (FHD) (1920 x 1080) screen. For practical purposes, this is as high-a-resolution as you want on a laptop. I've used laptops with Ultra High Definition (UHD), aka 4K, with 3840x2160 resolution, and I've found the text to be painfully small. This display is powered by an integrated Intel HD Graphics chipset. For networking, the X1 uses an Intel Wi-Fi 6 AX201 802.11AX with vPro (2 x 2) & Bluetooth 5.0 chipset. I've used other laptops with this wireless networking hardware and it tends to work extremely well. The entire default package has a base price of $2,145. For now, it's available for $1,287. If you want to order one, be ready for a wait. You can expect to wait three weeks before Lenovo ships it to you.

Intel: 10nm Tiger Lake CPUs Will Be in 50 New Laptops Coming This Fall (venturebeat.com) 45

Intel took the wraps off its not-so-secret central processing units (CPUs) code-named Tiger Lake, built with a 10-nanometer manufacturing process. It may has well been called Tiger Leak. From a report: The 11th Generation Intel Core Processor models include the Intel Core i7-1185G7 chip, with a base 3GHz frequency that can be boosted to 4.8GHz. The Santa Clara, California-based company has dual-core and quad-core variants in the new family, which will be used in high-powered laptops coming this fall. Intel is also unveiling the Intel Xe 12th Gen integrated graphics processing unit (GPU), which replaces the Iris Plus integrated GPU. It has improved AI performance, Thunderbolt 4 input-output, and software optimizations. Intel said it has 20% better CPU performance and two times the graphics performance than the previous generation. With the integrated GPU, Intel said it can deliver frame rates in games that are two times faster than previous models. All told, there are nine new Tiger Lake chips. The chips are the top of the line for now as Intel faces severe competition from rival Advanced Micro Devices, which uses external producers such as TSMC to make its chips and is making historic market share gains. Intel normally makes its own chips, and it is rumored to be talking to TSMC for contract manufacturing, but that deal won't come in time for Tiger Lake. "We're leading the ecosystem forward to deliver new PC experiences," said Gregory Bryant, executive vice president of client computing at Intel, in a briefing.

Nintendo Plans Upgraded Switch Console and Major Games for 2021 (bloomberg.com) 49

Nintendo plans to debut an upgraded model of its Switch console next year along with a lineup of new games, Bloomberg reported Tuesday, citing people familiar with the matter said, ceding 2020's holiday spotlight to rival devices from Sony and Microsoft. From the report: The specifications of the new machine have yet to be finalized, though the Kyoto-based company has looked into including more computing power and 4K high-definition graphics, people briefed on the strategy told Bloomberg News, asking not to be identified because it's private. Nintendo faces stiff competition for gamers' attention this fall as the PlayStation 5 and Xbox Series X are set to arrive in time for the shopping season. The release of the upgraded Switch would be coupled with, or followed by, a slew of games from Nintendo itself and related outside studios, the people said. Those games would address a wide range of players, from casual gamers seeking small doses of escapism to more devoted fans putting in marathon gaming sessions. The focus on next year's pipeline explains Nintendo's relatively quiet software release schedule so far this year, the people said.

Microsoft Warns Court That Apple Blocking Epic Will Hurt Games Business (cnbc.com) 127

Microsoft has stepped into the brewing legal battle between Apple and Epic Games over the former's policies with regard to its ubiquitous App Store. From a report: In a declaration filed on Sunday, a senior Microsoft engineer said that allowing Apple to block Epic Games' developer account would deal a significant blow to game makers including Microsoft by making them unable to use Epic's Unreal Engine. The Unreal Engine, a type of gaming engine, is a widely used set of technologies that provides a framework for the creation of three dimensional graphics. Epic licenses the engine to companies that use the technology for a fee. "If Unreal Engine cannot support games for iOS or macOS, Microsoft would be required to choose between abandoning its customers and potential customers on the iOS and macOS platforms or choosing a different game engine when preparing to develop new games," Kevin Gammill, Microsoft's general manager for Gaming Developer Experiences, said in the declaration.

He added that "Apple's discontinuation of Epic's ability to develop and support Unreal Engine for iOS or macOS will harm game creators and gamers." While there are alternative gaming engines, Gammill said that "very few" are available with as many features and the same functionality. The declaration came as part of a lawsuit brought by Epic against Apple over the iPhone maker's rules guaranteeing itself a 30% cut of in-app purchases. The suit is filed in U.S. District Court for the Northern District of California. Epic Games tested Apple's policy by sidestepping the rule in an update to its hit game Fortnite, and then sued after Apple removed the game from the App Store. The company has brought a similar suit against Google over its Play Store.

New Blender Add-On Accurately Models Subatomic Particles, Involves Community with Contest (energywavetheory.com) 101

BlenderArtists.org writes: To build and model the universe from the Planck scale to galactic scales requires an incredible number of mathematical computations to simulate particles and their interactions, yet the framework of nature and the physics of these interactions should be simple. Blender's physics engine provides a good base to begin this project, but it will take work from the community to accurately model subatomic particles.
That's where "Quantum Microscope" comes in. It's a newly open sourced add-on for Blender that simulates subatomic particles and the formation of matter using classical physics. "It provides a microscopic look at molecules, atoms, atomic nuclei, particles and spacetime, using the theoretical model from Energy Wave Theory," explains its web page, linking to a video summarizing some of its features.

And that's just the beginning, writes Slashdot reader atomicphysics: A contest begins September 1, 2020 for developers to enhance the add-on, or create a new simulator meeting project requirements to use classical physics for the quantum realm, with at least $15,000 in prizes being awarded over the next year.

Parallels Desktop 16 Supports macOS Big Sur and Smoother PC 3D Graphics (venturebeat.com) 29

As Apple's Mac computers begin their two-year transition from Intel- to Apple-developed CPUs later this year, one feature that's going away is Boot Camp -- the Mac's ability to boot directly into Windows and run PC apps natively. But Corel's Parallels Desktop will still be there to let Mac users run Windows, and in this year's version 16, it will thankfully be faster, more compatible, and easier to use than ever. From a report: Like Parallels Desktop 15, version 16 is an emulator that allows users to load a complete operating system or individual apps within macOS, treating them as windows within the Mac environment. Once again, high-end Business, mid-range Pro, and regular Standard versions are available. With the latest Business version of Parallels Desktop, an IT department can create, deploy, and remotely manage a profile-customized Windows system that Mac users download in a compact file size and expand on their own machines. A simpler Pro version includes the file-compacting feature used to more easily transfer virtual machines between computers, achieving as much as 20 times compression for Linux installs and 75% faster Linux git status executions. The standard version includes a manual Free Up Disk Space feature with archiving and space reclaiming options.

Nvidia in Advanced Talks To Buy Chip Giant Arm (bloomberg.com) 66

Nvidia is in advanced talks to acquire Arm, the chip designer that SoftBank Group bought for $32 billion four years ago, Bloomberg reported Friday, citing sources familiar with the matter. From the report: The two parties aim to reach a deal in the next few weeks, the people said, asking not to be identified because the information is private. Nvidia is the only suitor in concrete discussions with SoftBank, according to the people. A deal for Arm could be the largest ever in the semiconductor industry, which has been consolidating in recent years as companies seek to diversify and add scale. Cambridge, England-based Arm's technology underpins chips in products including Apple Inc. devices and connected appliances. Financial Times, which has also independently reported about the deal talks today, adds: Buying Arm would further consolidate Nvidia's position at the centre of the semiconductor industry, at just the moment when the British chip designer's technology is finding broader applications beyond mobile devices, in data centres and personal computers including Apple's Macs. Arm would transform Nvidia's product line-up, which until now has largely focused on the high end of the chips market. Its powerful graphics processors -- which are designed to handle focused, data-intensive tasks -- are typically sold to PC gamers, scientific researchers and developers of artificial intelligence and self-driving cars, as well as cryptocurrency miners. The deal could alarm Arm's other big licensees, including Apple, Broadcom and Qualcomm, which may fear a unique asset being taken over by a potential competitor such as Nvidia.

A sale would mark a stunning reversal for SoftBank founder Masayoshi Son, who declared that Arm would be the linchpin for the future of the technology investment conglomerate. The company has failed to thrive under SoftBank, according to people with direct knowledge of the matter. Neil Campling, an analyst at Mirabaud, noted that Arm's annual revenues had risen from $1.2bn to $1.9bn since SoftBank bought it in 2016, while Nvidia's have roughly tripled in the same timeframe.

Intel Reorganizes In Wake of 7nm Woes; Chief Engineering Officer To Depart (anandtech.com) 119

FallOutBoyTonto shares a report from AnandTech: Coming in the wake of last week's disclosure that their 7nm yields are roughly a full year behind schedule, Intel this afternoon has announced that they are reorganizing the technology side of the company. Key to this change is that Intel is breaking up its monolithic Technology, Systems Architecture and Client Group (TSCG) into several smaller groups, all of which will report directly to CEO Bob Swan. Meanwhile Intel's chief engineering officer, Dr. Murthy Renduchintala, who had been leading the TSCG, will be departing the company at the end of next week. The reorganization is effective immediately.

As a result of this reorganization, TSCG is being broken up into five groups focusing on manufacturing and architecture. These are:

- Technology Development: Focused on developing next-generation process nodes. Led by Dr. Ann Kelleher.
- Manufacturing and Operations: Focused on ramping current process nodes and building out new fab capacity. Led by Keyvan Esfarjani.
- Design Engineering: A recently-created group responsible for Intel's technology manufacturing and platform engineering. Led on an interim basis by Josh Walden while Intel searches for a permanent leader.
- Architecture, Software and Graphics: Developing Intel's architectures and associated software stacks. Led by Raja Koduri (continuing).
- Supply Chain: Handling Intel's supply chain and relationships with important suppliers. Led by Dr. Randhir Thakur (continuing).

Huge Apparent Leak Unearths Nintendo's Prototype History (arstechnica.com) 21

An anonymous reader quotes a report from Ars Technica: A massive leak of apparent Nintendo source code is giving gamers a rare, unauthorized look at Nintendo's development process dating back to the Super NES era. The massive trove of files, first posted to 4chan Friday and quickly dubbed the "Gigaleak" by the community, includes compilable code and assets for Super NES, Game Boy, and N64 games in the Mario, Mario Kart, Zelda, F-Zero, and Pokemon series. Hidden among that code is a bevy of pre-release art and sound files that have never seen the light of day, as well as fully playable prototype versions of some games. Modders and homebrew developers have been digging through the trove of data over the weekend and taking to Twitter and YouTube with their discoveries. Among the most interesting findings:

- A version of Super Mario 64 including data for a 3D model of Luigi (likely for the scrapped two-player mode). Players have inserted that model into the ROM to create video of Luigi running around. The leak also includes few unused test rooms for the game.
- A Yoshi's Island prototype featuring differences in the map screen, interface, music (and including the prefix "Super Mario Bros. 5" in Japanese). The prototype also features two apparently unused mini-games (No. 1, No. 2) and some unused test levels.
- Pokemon prototypes featuring early and unused sprite designs for many monsters.
- An original prototype named "Super Donkey" featuring a Rayman-style character in a Yoshi's Island-styled world [Update: A previous version of this post mischaracterized the music in this video. Ars regrets the error].
- Sprite data for Luigi giving an apparent middle finger and Bowser outside of his clown-copter in Super Mario World. The code also contains multiple early designs for Yoshi (some of which match art previously revealed in interviews with Nintendo developers) and a completely new map screen design (which also matches previously revealed screenshots).
- A version of Star Fox 2 with previously unseen characters.
- High-quality voice samples from Star Fox 64, F-Zero X and Super Mario 64 before they were compressed to fit on relatively small N64 cartridges.
- Graphics for a Pilotwings prototype called Dragonfly, previously seen only in grainy magazine screenshots.

Nvidia Reportedly Could Be Pursuing ARM In Disruptive Acquisition Move (hothardware.com) 89

MojoKid writes: Word across a number of business and tech press publications tonight is that NVIDIA is reportedly pursuing a possible acquisition of Arm, the chip IP juggernaut that currently powers virtually every smartphone on the planet (including iPhones), to a myriad of devices in the IoT and embedded spaces, as well as supercomputing and in the datacenter. NVIDIA has risen in the ranks over the past few years to become a force in the chip industry, and more recently has even been trading places with Intel as the most valuable chipmaker in the United States, with a current market cap of $256 billion. NVIDIA has found major success in consumer and pro graphics, the data center, artificial intelligence/machine learning and automotive sectors in recent years, meanwhile CEO Jensen Huang has expressed a desire to further branch out into the growing Internet of Things (IoT) market, where Arm chip designs flourish. However, Arm's current parent company, SoftBank, is looking for a hefty return on its investment and Arm reportedly could be valued at around $44 billion, if it were to go public. A deal with NVIDIA, however, would short-circuit those IPO plans and potentially send shockwaves in the semiconductor market.

AMD Brings Power And Performance Of Ryzen 4000 Renoir Processors To Desktop PCs (hothardware.com) 42

MojoKid writes: Today AMD took the wraps off a new line of desktop processors based on its Zen 2 architecture but also with integrated Radeon graphics to better compete against Intel with OEM system builders. These new AMD Ryzen 4000 socket AM4 desktop processors are essentially juiced-up versions of AMD's already announced Ryzen 4000 laptop CPUs, but with faster base and boost clocks, as well as faster GPU clocks for desktop PCs. There are two distinct families AMD Ryzen 4000 families, a trio of 65-watt processors that include the Ryzen 3 4300G (4-core/8-thread), Ryzen 5 4600G (6-core/12-thread), and the flagship Ryzen 7 4700G, offering 8 cores/16 threads, base/boost clocks of 3.6GHz/4.4GHz, 12MB cache, and 8 Radeon Vega cores clocked at 2100MHz. AMD is also offering three 35-watt processors -- Ryzen 3 4300GE, Ryzen 5 4600GE, and the Ryzen 7 4700GE -- which share the same base hardware configurations as the "G" models but slightly lower CPU/GPU clocks to reduce power consumption. In addition AMD also announced its Ryzen Pro 4000 series for business desktops, which also include a dedicated security processor and support for AMD Memory Guard full system memory encryption. As you might expect, specs (core/cache counts, CPU/GPU clocks) for the Ryzen Pro 4000G (65W) and Ryzen Pro 4000GE (35W) largely line up with their consumer desktop counterparts.

Should We Plan For a Future With Fewer Cars? (nytimes.com) 396

The New York Times ran a detailed piece (with some neat interactive graphics) arguing "cities need to plan for a future of fewer cars, a future in which owning an automobile, even an electric one, is neither the only way nor the best way to get around town..."

It asks us to imagine a world where there's suddenly more room for two-way bike lanes, wider sidewalks, and car-free bus lanes. But it also looks at our current conundrum: Automobiles are not just dangerous and bad for the environment; they are also profoundly wasteful of the land around us, taking up way too much physical space to transport too few people... And cars take up space even while they're not in use. They need to be parked, which consumes yet more space on the sides of streets or in garages. Cars take up a lot of space even when they're just looking for parking... New York's drivers are essentially being given enormous tracts of land for their own pleasure and convenience. To add to the overall misery of the situation, though, even the drivers are not especially happy about the whole deal, because despite all the roadway they've been given, they're still stuck in gridlock...

"The one thing we know for sure, because we understand geometry, is that if everyone drives, nobody moves," Brent Toderian, the former chief planner for the city of Vancouver, British Columbia, told me. Even if you're a committed daily driver, "it's in your best interest for walking, biking and public transit to be as attractive as possible for everyone else — because that means you're going to be able to drive easier..." Instead of fighting a war on cars, Toderian told me, urbanists should fight a war on car dependency — on cities that leave residents with few choices other than cars. Alleviating car dependency can improve commutes for everyone in a city...

At the moment, many of the most intractable challenges faced by America's urban centers stem from the same cause — a lack of accessible physical space. We live in a time of epidemic homelessness. There's a national housing affordability crisis caused by an extreme shortage of places to live. And now there's a contagion that thrives on indoor overcrowding.

Given these threats, how can American cities continue to justify wasting such enormous tracts of land on death machines?

AMD Delivers a Major Mobile Efficiency Milestone (thurrott.com) 56

AMD has exceeded its goal to improve the energy efficiency of its mobile processors by 25 times by 2020. According to Thurrott, " The new AMD Ryzen 7 4800H mobile processor improves on the energy efficiency of the 2014 baseline measurement by 31.7 times, the firm says, while offering 'leadership performance' for portable PCs." From the report: "We have always focused on energy efficiency in our processors, but in 2014 we decided to put even greater emphasis on this capability," AMD CTO Mark Papermaster says in a prepared statement. "Our engineering team rallied around the challenge and charted a path to reach our stretch goal of 25 times greater energy efficiency by 2020. We were able to far surpass our objective, achieving 31.7 times improvement leading to gaming and ultrathin laptops with unmatched performance, graphics and long battery life. I could not be prouder of our engineering and business teams."

As AMD notes, greater energy efficiency leads to significant real-world benefits, including improved battery life, better performance, lower energy costs, and reduced environmental impact from computing. And with the focus in mobile computing hardware switching to performance-per-watt these days, AMD is trying to position itself as the traditional PC chipmaker that can rise to the ARM challenge.

Windows 10 Linux Subsystem: You Get GPU Acceleration -- With Intel, AMD, Nvidia Drivers (zdnet.com) 56

Nvidia, Intel and AMD have announced their support for Microsoft's new effort to bring graphics processor support to the Windows 10 Windows Subsystem for Linux to enhance machine-learning training. From a report: GPU support for WSL arrived on Wednesday in the Dev Channel preview of Windows 10 build 20150 under Microsoft's reorganized testing structure, which lets it test Windows 10 builds that aren't tied to a specific future feature release. Microsoft announced upcoming GPU support for WSL a few weeks ago at Build 2020, along with support for running Linux GUI apps. The move on GPU access for WSL is intended to bring the performance of applications running in WSL2 up to par with those running on Windows. GPU compute support is the feature most requested by WSL users, according to Microsoft. The 20150 update includes support for Nvidia's CUDA parallel computing platform and GPUs, as well as GPUs from AMD and Intel. It also supports DirectML (Direct Machine Learning), Microsoft's Windows 10 API for hardware-accelerated machine learning.
