Amazon's Sidewalk neighborhood WiFi should arrive later this year.
Apple just bought a low-power AI startup
Apple has acquired another Seattle-based AI startup, Xnor.ai. The startup specializes in low-power edge-based tools that allow AI to operate on devices, rather than in the cloud. The tech could allow Apple to bring edge-based AI software to future iPhone models.
AMD will share its graphics technology with Samsung
AMD stole the spotlight at Computex 2019, where it shared details on its third generation Ryzen CPUs and first Navi GPUs. But that's not the only big news AMD has in store. Today, the company announced a multi-year partnership with Samsung, in which AMD will license its Radeon graphics IP for use in Samsung smartphones and other mobile applications.
The Apple Watch has a low-power mode that only tells the time
If you're jonesing for an Apple Watch, you probably want to do a lot with it. But what if you're headed out to a party and would rather not risk staring at a dead screen when you're wondering how late it is? Don't worry, you're covered. The New York Times understands that the Watch has an unannounced Power Reserve option that limits the device to telling time. While it's not a completely unique feature (other watches do similar things), it's definitely helpful -- and it's a departure for Apple, whose mobile devices haven't had these kinds of extreme energy-saving modes until now. Tim Cook and crew aren't likely to make a big deal of Power Reserve at Apple's March 9th event, assuming it shows up, but it could be one of the Watch's most important real-world features.
Broadcom introduces low-power WiFi and Bluetooth chips for the Internet of things
The Internet of things -- that nebulous term usually associated with interconnecting everyday objects in a meaningful way -- is in the news again. Yesterday, Broadcom announced that it's launching a couple cost-effective, power-efficient wireless chips geared towards appliances, home automation and wearable devices. The first SoC, BCM4390, incorporates a highly-efficient WiFi radio for embedded use in products such as weight scales, thermostats and security cameras. It fits into the company's range of Wireless Internet Connectivity for Embedded Devices (WICED) chips. The second SoC, BCM20732, features an ultra low-power Bluetooth transceiver and targets devices like heart rate monitors, pedometers and door locks. Broadcom's also contributing its Bluetooth software stack to the Android Open Source Project with support for both standard and Bluetooth Smart hardware. Does this mean our long-awaited smart toaster's just around the corner? We sure hope so. Follow the source links below for more info.
Acer unveils space-saving ME mini tower and XC desktops for (low) power users
The arrival of Windows 8 is a good excuse for the PC industry to flood the market with so much hardware, consumers will be blinded by so much choice. Acer's jabbing its digits into your eyes with its new lineup of low-end desktops for the casual user. The ME micro towers will take an Intel Core i5 or I7, 2TB HDDs and up to 16GB of RAM. If you don't have anywhere else to stash your smartphone, the chassis comes with a recess desk on top with a USB port for easy charging. Those looking for something a little less demanding can pick up an XC desktop, a space-saving unit that will take an Intel Core i3, a 1TB HDD and up to 6GB of RAM. Prices for the ME begin at $700, while the cheaper XCs will set you back a much more modest $400.
Low-power chip guru quits Samsung for Apple, with heavily implied implications
The iPhone 5 already proved Apple's desire to move away from existing processor designs and exert more control over these fundamental components. Is it too crazy to imagine that Cupertino would like the same sense of freedom with its laptops? Perhaps not, especially since the biggest company in the world just hired a guy called Jim Mergard, who helped to pioneer AMD's low-power Brazos netbook chips and who had only recently moved to Samsung. A former colleague of Mergard's, Patrick Moorhead, told the WSJ that he would be "very capable of pulling together internal and external resources to do a PC processor for Apple" -- possibly based on a mobile-style SoC (system-on-chip) rather than a traditional PC approach. That's pure speculation of course, but funnily enough it's where Intel seems to be headed too.
AMD enters Windows 8 tablet fray with Z-60 chip: 'all-day' battery life, graphics 'you would never expect'
If you know AMD mainly for its laptop and desktop processors, then some readjustment may be in order: as of now, the company is rushing head-long into the market created by Surface fever and the need for ultra lean tablet chips that can handle Windows 8. Specifically, we're looking at the official launch of the Z-60, formerly known as Hondo, which AMD says will arrive in tablets "later this year" and satisfy even our most unreasonable demands for Windows 8 hybrids that last 10+ hours in tablet mode and which turn into full-scale PCs when docked. And if you're thinking that Intel made much the same pledge during its recent Clover Trail announcement, then you're dead right -- we actually have all the makings here of a proper old-fashioned chip fight. Read on for a spot of pre-match banter.
How the iPhone 5 got its 'insanely great' A6 processor
It's hard not to be impressed by the A6 engine in the new iPhone 5, since it's now proven to deliver a double-shot of great performance and class-leading battery life. But silicon stories like that don't happen over night or even over the course of a year -- in fact, analyst Linley Gwennap has traced the origins of the A6 all the way back to 2008, when Steve Jobs purchased processor design company P.A. Semi and set one of its teams to work on creating something "insanely great" for mobile devices. Although Apple is steadfastly secretive about its components, Gwennap's history of the A6 (linked below) is both plausible and a straight-up good read for anyone interested in the more fundamental aspects of their gadgets. Whereas the A5 processor stuck closely to ARM's Cortex-A9 design, Gwennap is convinced -- just like Anandtech is --that the A6 treads a very different path: it's still based on ARM's architecture and it's likely fabricated by Samsung using a cutting-edge 32nm process, but it's an in-house vision of what a mobile chip should be. It's the culmination of four years of hard work and perhaps half a billion dollars of investment. That's not to say it's the most powerful chip out there, or even the chip most tailored to its host device -- after all, Samsung also designs great chips for some of its own smartphones. Indeed, Gwennap says that the A6 is probably a dual-core processor that is no more complex than Qualcomm's Snapdragon S4 (let alone the S4 Pro) or the forthcoming generation of Cortex-A15 chips, while its clock speed could be as low as 1.2GHz -- versus a 1.6GHz quad-core Exynos in the Note II and even a 2GHz Intel chip in Motorola's new RAZR i. However, Gwennap predicted that even if the A6 falls short of its rivals "in raw CPU performance," it'd make up for it in terms of low power consumption -- which is precisely what we've confirmed in our review.
AMD's Hondo tablet chip will happily run Windows 8 and Linux, but not Android
Today's business jargon gem: TAM, Total Addressable Market. AMD feels that Windows 8 comes with plenty of the stuff, so it sees no commercial need to make its forthcoming tablet chip -- codenamed Hondo -- play nice with Android as well. Speaking to The Inquirer, corporate VP Steve Belt said it was a "conscious decision" not to go after compatibility with Google's OS, because AMD doesn't want to spread itself into "other markets." What could this mean for us tablet-buyers? No dual-booting Windows / Android magic on AMD devices, for one thing, which is perhaps a shame now that ASUS has shown off the combo's potential. On the other hand, Belt made it clear that Hondo will support Linux, which -- for now, at least -- is more than can be said of Intel's rival low-power silicon, Clover Trail.
Samsung teasing Series 5 Hybrid PC announcement at IFA
While we fritter away our hours sharing cat pictures on Facebook, Samsung prefers to issue forth teasers for its forthcoming products. The latest is the above snap, raising hopes that its Series 5 Hybrid PC will be formally announced a teutonic trade show IFA this week. The 11-inch Transformer-esque device features a tablet that's magnetically-attached to a keyboard dock, running "full" Windows 8 on Intel's Clover Trail x86 architecture. In addition to Redmond's newest OS, it'll use native versions of the S-Pen apps we've used on the Galaxy Note 10.1, although it's probably too much to hope that it'll be able to make calls like its cousin.
Facebook to backup its servers with low-power storage devices at 'Sub-Zero' data center
Data backups come in all shapes and sizes. For some, they take the form of external hard drives or a slice of the amorphous cloud. As for Facebook, its upcoming solution is low-power deep-storage hardware contained within a 62,000 square-foot building in Prineville, Oregon near its existing Beaver State data center. Unofficially referred to as "Sub-Zero," the facility will store a copy of the social network's data in case its primary servers need to be restored in an emergency. Rather than continuously power HDDs that are only occasionally used, the new setup can conserve energy by lighting-up drives just when they're needed. One of the company's existing server racks eats up around 4.5 kilowatts, while those at Sub-Zero are each expected to consume approximately 1.5 kilowatts once they're up and running. Tom Furlong, Facebook's vice president of site operations, told Wired that there are hopes to create a similar structure alongside the firm's North Carolina data center. Since the Prineville project is still being planned, Zuckerberg & Co. have roughly six to nine months to suss out all the details before your photos are backed up at the new digs.
Ask Engadget: Best sub-$310 power-efficient HTPC for a caravan?
We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget inquiry is coming to us from Is from Martin, who is looking for a hyper-efficient media streamer for his retro caravan. If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com. "My partner and I are renovating a small '70s caravan and would like a power-efficient media center/PC purely to watch our library of movies and TV shows.

AMD announces 900MHz version of the Radeon HD 7750, calls it 'the other 7750'
The original Radeon HD 7750 won plaudits for its low-wattage performance and $109 price tag, but now AMD's decided to put out an additional version with 100MHz more clock whizz. The new card also happens to be called the Radeon HD 7750, and it'll sit alongside its doppelganger on the shelves of the world's computer stores just daring you spot the difference. How will you do that? By checking if it requires a separate power supply: the original 7750 was powered entirely through the PCIe slot, limiting its power to 75W and hence its clock speed to 800MHz, while the new one accepts additional power to deliver slightly more grunt and stay ahead of looming competition from NVIDIA. XFX has already jumped aboard with the 7750 Black Edition Double Dissipation priced at $115 after a rebate, and AnandTech says other vendors will follow suit. So, unless you're totally out of power jacks, you know what to look for. Image courtesy of Newegg.
Samsung mass-produces 4-gigabit LPDDR2 memory, aims to make 2GB a common sight in smartphones
Samsung started making 2GB low-power mobile memory last year, but as the 1GB-equipped phone you likely have in your hand shows, the chips weren't built on a wide-enough scale to get much use. The Korean company is hoping to fix that now that it's mass-producing 20-nanometer, 4-gigabit LPDDR2 RAM. Going to a smaller process than the 30-nanometer chips of old will not just slim the memory down by a fifth, helping your smartphone stay skinny: it should help 2GB of RAM become the "mainstream product" by the end of 2013, if Samsung gets its way. New chips should run at 1,066Mbps without chewing up any more power than the earlier parts, too, so there's no penalty for using the denser parts. It's hard to say whether or not the 20nm design is what's leading to the 2GB of RAM in the Japanese Galaxy S III; we just know that the upgraded NTT DoCoMo phone is now just the start of a rapidly approaching trend for smartphones and tablets.
Panasonic preps samples of next-gen ReRAM devices, NAND preps for early retirement
The Galaxy S III may rock an impressive battery life, but if Panasonic has its way, even greater benchmarks could be on the horizon. The company is ready to start making samples of a new ReRAM microcontroller, and -- like Sharp and Elpida -- it could start mass production as soon as next year. Here's a little refresher: ReRAM is a new kind of memory with re-write speeds far superior to NAND because it doesn't need power to hold onto information. Panny's chip will initially be used in simple devices like fire alarms, but the tech could eventually find its way into our TVs and even smartphones and tablets. But seriously, are we even capable of living in a NAND-free world?
Series revisits ARM's humble beginnings, BBC Micro and all
If you read our interview with ARM co-founder John Biggs, you know the company behind the processor in most smartphones had quite modest beginnings, what with an office in a barn and all. But Biggs is only part of the story, and Reghardware fleshes the rest out with a two-part series on the "unsung heroes of tech": Sophie Wilson, Steve Furber and Herman Hauser, the team behind Acorn Computers, the British PC company that spawned ARM in the mid-80s. We'll let you click through to the source links to take the journey yourself, but here are a few highlights: earning a computer contract with the BBC, happening upon ARM chips' low power consumption by accident and striking gold thanks to a partnership with Apple.
The Engadget Interview: AMD's Sasa Marinkovic
This isn't the easiest time to be an AMD fan. The company's eight-core FX-8150 desktop chip was widely panned on the review circuit, and then NVIDIA's GTX 680 graphics card ran off with Radeon HD's thunder. Even when you look at notebook processors, where AMD has long excelled with its Fusion APUs, the hype wars currently favor Ultrabooks and Ivy Bridge. Affection for the gamers' brand and its ATI back-story may make this stuff uncomfortable, but the predicament is already starting to mess with AMD's balance sheet. Which raises the obvious question: what's to be done? Sasa Marinkovic, AMD's Head of Desktop and Software Product Marketing, bravely took up the challenge of providing his side of the story -- even after we warned him that we'd try to disrupt his flow with accusatory glances. In the end, we did get him to acknowledge some recent hard knocks, particularly with respect to the FX chips and their (lack of) single-threaded performance. But we also got some insight into the mind of a chap who remains genuinely and abundantly confident about his employer's future. Read on and see for yourself.
AMD confirms Trinity and Brazos 2.0 shipping now, globally available 'soon'
Any troglodytes out there who didn't know that AMD's next APU architecture is inbound? If so, we're gonna toast marshmallows outside your cave and give you a little pre-brief: Trinity will be a range of processors for "performance" notebooks and desktop PCs, which will continue in AMD's Fusion tradition of providing both the CPU and discrete-class graphics in a single-chip, power-efficient design. A potential rival to Ivy Bridge and the coming stampede of Ultrabooks? Yes indeed, although it's too early to say how closely matched these athletes will be, despite some early indications of 4GHz+ clock speeds. Judging from our recent look at a Trinity-packing Compal laptop, undercutting Ultrabooks on price will also be part of AMD's strategy -- along with throwing out Brazos 2.0 APUs to mop up the extreme low-power category. After all, Ivy Bridge probably won't offer truly discrete-class graphics until it's paired with an add-on GPU, which will inevitably bump up its price for gamers and multimedia types. If Trinity serves up great visuals and next-gen performance all in one go, AMD's accountants might be able to leave their subterranean hideouts too. [Thanks, Tyler]
AMD has a server chip for the cheap seats: the 'desktop-like' Opteron 3200
So, AMD's 2012 rampage continues. Having outed a full stack of Radeon HD 7000-series graphics cards on the consumer side of things, it's now ready release the next in its line of Opteron enterprise server chips. Like the 4200 and 6200 series before it, the Opteron 3200 is based on the Bulldozer architecture. It comes in four or eight-core configurations, with 45W to 65W power consumption, plus a 2.7GHz base frequency that gets a 1GHz adrenalin kick in Turbo Core mode (which prioritizes half the cores and shuts down the other half). However, the 3200 series is designed to offer cloud and web hosting server functionality in a cheaper, "desktop-like infrastructure", which means these processors squeeze into a regular AM3+ socket and undercut comparable Xeons by up to $90. Can we expect server builders like SeaMicro to switch to these processors instead of Intel? Oh, you can count on it.
