Qualcomm's latest Snapdragon chips include two with built-in 5G
Qualcomm just outlined the performance landscape for many of 2020's Android phones -- the company has introduced the Snapdragon 865, 765 and gaming-oriented 765G. They should improve performance in categories like AI and 8K video capture (Qualcomm won't share much more until December 4th), but this time around the highest-end chip isn't the star. The upper mid-range 765 series represents Qualcomm's first systems-on-a-chip with integrated 5G, saving them from using separate, power-hungry modems to take advantage of next-gen wireless. That could extend battery life, of course, but it should also make 5G handsets more affordable.
NVIDIA, Epic Games bringing Unreal Engine 3 to Windows 8 and Windows RT (video)
NVIDIA and Epic Games have successfully ported the full PC version of Unreal Engine 3 to both Windows 8 and, more importantly, Windows RT. Demonstrating the achievement on a Tegra 3-powered ASUS Vivo Tab RT, it played a buttery-smooth version of Epic Citadel, suggesting that developers of both PC and Xbox games should have no problem in bringing them over to the new operating system. It also casually mentioned that both Gears of War and Mass Effect were built on the engine, heavily implying that we could see titles of that caliber coming to Microsoft's low-power OS once it makes it debut on October 26th, but we'll let you decide for yourself after the break.
Intel's full Atom 'Bay Trail' roadmap leaked: 22nm, Ivy Bridge graphics, quad-core
We saw a leaked hint of what was coming for Intel's Valleyview system-on-a-chip (SoC), but now the full plan appears to have been outed by Chinese blog Expreview. The lineup will feature four models of the 22nm chips, with the D- and M-series looking to replace the Cedar Trail 32nm SoC chips used in current netbook and low-end desktop devices. The I-series is for embedded and industrial use, while the T-series would appear in tablets and other small form-factor devices, according to the leaked slides. That model would supersede the Clover Trail SoCs, which are only just arriving themselves in upcoming Windows 8 slates like the Acer W510 or Asus Tablet 810. The chips should offer a burly horsepower bump over their predecessors, with up to four cores and clock speeds topping out at 2.4Ghz. The icing on the cake will be the integrated Gen 7 graphics engines of Ivy Bridge fame, featuring the same HD 4000 and HD 2500 GPU's as the grownup chips, but with only four "execution units" instead of the 16 you'd find there. That would offload functions like video decoding and 3D rendering from the CPU and allow simultaneous display to a TV or monitor. Bay Trail would also support 8GB of DDR3 RAM, double that of the "last" gen, as well as USB 3.0, SATA 2.0 and a host of other connection options. If the leak is accurate, the processors would arrive sometime next year, we'll just have to wait and see if that's soon enough for Intel to take a run at its formidable competition.
Project Moonshot take two: HP's low-power Gemini servers let go of ARM's Calxeda for Intel's Centerton
Last we'd heard of HP's Project Moonshot, that effort to create low-energy servers was set to ride on the back of the Calxeda SoC. But for the rollout of its production-ready "Gemini" models, the company's changed tack, replacing the previously announced ARM chips for Intel's Centerton. Why the sudden swap? Well, it seems that new Atom processor delivers the same energy-sipping promise of its predecessor, while also adding 64-bit support, a broader software ecosystem, error correcting code memory and hardware virtualization. That's all well and good, but when you boil it down to layman's terms, HP's really just angling for the ultimate in efficiency and it plans to do that by providing these compact servers in "a [smaller] footprint" than currently available setups. The system's still not quite ready for primetime consumption, given its very recent public outing, however, demo units are in the pipeline, with a planned launch for the end of 2012. If this sort of back-end geekery gets your blood flowing, feel free to hit up the official presser after the break.
Newport Media claims tiniest, lowest-power 802.11n WiFi chip yet, smartphones get a little less thirsty
Cellular chipsets get all the love these days, but it's WiFi that's still the most ubiquitous -- and often the most consistent drain on the battery. Newport Media might have that last problem solved through its new NMC1000 chip. The part is billed as the lowest-power 802.11n wireless system-on-a-chip you'll find, and potentially a big help to smartphones and other devices that lean heavily on a wire-free existence. At just 2.5mm (0.1 inches) square, the equally record-setting size should also please device makers trying to squeeze wireless into an exceptionally tiny footprint. If you're as excited about the prospect of WiFi everywhere as Newport's Stock Photography Woman above appears to be, you can get more details below and expect full-scale production in the fall.
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.
ST-Ericsson to pass off application processor business to STM, cut 1,700 jobs
It's not every day that ST-Ericsson crosses our radar twice, but in addition to reportedly signing a deal with HTC for developing low-end handset chips, the company just announced its plans for a turnaround. The message? A heavier focus on SoCs for smartphones and tablets, along with a push for even more partnerships to develop those products. While that all sounds rosy, ST-Ericsson is also ceding its application processor business -- employees, R&D and all -- to STMicroelectronics. All told, between the loss of its application processor business and other reshuffling, the company expects to shed around 1,700 jobs -- and save about $320 million annually. Those bittersweet details and more await you in the press release after the break.
Apple TV (2012) uses same chip as iPad 2 but only uses one core
The latest Apple TV was torn down recently, but it still has a surprise or two up its sleeve. According to a report in Chipworks, the 2012 unit has a dual-core A5 chip that's only using one of its two cores. They discovered it's actually the same 32nm SoC found in newer iPad 2 units. You can read more about the Apple TV's underlying architecture on Chipworks's website. [Via Engadget]
Intel plans to roll out Ivy Bridge based Xeon E3s, low-power Atom chips for micro servers
Ask any gardener, once you let ivy grow, it gets everywhere. Even though Intel just planted a fresh family of Sandy Bridge-based server CPUs, reports of a new line of Xeon E3 chips sporting the firm's next generation architecture are sprouting up. The new Ivy Bridge server chips use the firm's 3D Tri-Gate transistors to improve performance without using more power. For micro servers looking for an even smaller power footprint, Intel is introducing an Atom-based system on a chip, dubbed Centerton. These new 64-bit chips will feature two Atom processor cores and consume only six watts of electricity. Intel hasn't said yet just where these new processors are going to end up, but mentioned that it had a few customers on board.
Researchers get CPUs and GPUs talking, boost PC performance by 20 percent
How do you fancy a 20 percent boost to your processor's performance? Research from the North Carolina State University claims to offer just that. Despite the emergence of fused architecture SoCs, the CPU and GPU cores typically still work independently. The University hoped that by assigning tasks based on each processor's abilities, performance efficiency would be increased. As the CPU and GPU can fetch data at comparable speeds, the researchers set the GPUs to execute the computational functions, while the CPUs did the prefetching. With that data ready in advance, the graphics processor unit has more resources free, yielding an average performance boost of 21.4 percent though it's unclear what metrics the researchers were using. Incidentally, the research was funded by AMD, so no prizes for guessing which chips we might see using the technique first.
Desktop apps may run on Win8 for ARM after all... maybe
The issue of whether or not the ARM edition of Windows 8 will support both desktop and Metro-style apps has been pretty hazy. Some have claimed it would, others that it wont and, even when they've issued denials of the nay-sayers, Microsoft has stopped short of saying that ARM hardware would offer a desktop mode for non-Metro apps. Well, buried in a post about improving power efficiency over at MSDN blogs was a passing reference to "both desktop and Metro style apps" running on "System on Chip (SoC) architectures." Some, including the well regarded Mary Jo Foley, have read this to mean that desktop apps will indeed work on ARM-powered Windows tablets. Now, this seems to make sense since all of the SoC coverage has been focused on the powerful new RISC chips getting crammed in new slates and smartphones, and we've heard that Win8 and Windows Phone 8 will share the same kernel. But, there is one tiny wrinkle in this narrative -- Intel will have its own SoC solutions soon enough thanks to Medfield, so the passage could simply be a reference to those x86 chips. You'll find the relevant excerpt at the via link.
Intel's 32nm Medfield SoC specs and benchmarks leak
Intel's Medfield may still be a ways from breaking into the smartphone and tablet market, but we're finally starting to get some concrete details on its specs and capabilities. VR-Zone got the nitty gritty on Chipzilla's first true SoC and it looks almost ready to run with the big dogs. A reference tablet, running at 1.6GHz with 1GB of RAM (which also packs Bluetooth, WiFi and FM radio) was put through some Android benchmarks and held it's own against a Tegra 2 and a Snapdragon MSM8260 -- which pulled a 7,500 and 8,000 in Caffeinemark 3, respectively. The admittedly higher clocked Atom scored an impressive 10,500, though power consumption on the pre-production chips was a bit higher than anticipated. At idle, the fledgling Medfield was sucking down 2.6W and spiking to 3.6W under load. Ultimately Intel hopes to cut those numbers to 2W at idle and 2.6W while pushing out HD video -- not far off from current-gen ARM SoC. Lets not forget though, benchmarks only tell part of the story -- we'll be waiting to see working hardware before declaring a victor.
HP and Calxeda's Moonshot ARM servers will bring all the boys to the yard (video)
HP and Calxeda's indiscreet partnership has been revealed to the world: Project Moonshot is a new server based around a brand new ARM-based EnergyCore system-on-chip. These new units are so efficient that a four core version, packing 4GB DRAM, consumes just five watts at full pelt -- for perspective, that's less than your average tablet. The other funky innovation is that all the server nodes now share a single power, cooling, management and storage system rather than carrying it themselves. In terms of space saving, the Redstone four unit chassis you can see in the image above can hold 288 of the little blighters. If you set your alarm clock early to learn more about efficient server architecture, head on past the break for two videos, including a tour of HP's server labs and some press release goodness.
HP to announce ARM-based servers next month, throw Intel a curveball
Sources close to Bloomberg and the Wall Street Journal say that HP is primed to help ARM wrestle its way into the server game next month, citing unannounced plans that may challenge Intel's corner on the market. HP is said to be working with Calxeda, an outfit with dreams of outclassing today's servers by selling OEMs an ARM-based system on a chip that can be used to build high performance racks with low energy footprints. ARM, HP and Calxeda all declined to comment, although a spokesperson for Calxeda mentioned that it has a product release event scheduled for November 1st. Intel doesn't seem too concerned, and told the Wall Street Journal that ARM architecture still had a few hurdles to jump before it was ready for the server game. "We believe the best-performing platform will win." Spoken like a true sportsman, Intel. Game on.
Freescale expands its family of i.MX50 chips, goes beyond e-readers this time
We had a feeling that Freescale was onto something when it debuted the i.MX508, a system-on-a-chip that carried the promise of $150 e-readers (and the reality of $129 ones). Given that, we can see where the execs at Freescale would be feeling a bit heady, and might wonder where else they could help push down prices. That's exactly what we have here: the outfit is trotting out three new i.MX50 processors and, as you can see in that handy chart up there, they all sit even lower in the lineup than the low-cost i.MX508. Like the i.MX508, they all pack an 800HMz ARM Cortex-A8 processor, among other similar specs. The new i.MX507, in particular, resembles the i.MX508 in that it's designed to work with E Ink displays, though it lacks graphics acceleration, and Freescale imagines it'll instead find a home in outdoor signs and smart labels. Moving on down the line, the i.MX502 and the i.MX503 were both intended for devices with LCD -- not electronic paper -- displays, with the latter offering OpenVG graphics acceleration. If Freescale's predictions are on the money, you'll find the lower-end i.MX502 in DECT phones and vending machine displays, and the i.MX503 in personal navigators and medical monitoring tablets, among other use cases. For now, companies are sampling the chips, but they'll start shipping later this quarter for a song -- less than $10 for the i.MX502 at volume cost. Full PR after the break, and lots more technical details at the source link.
Apple reportedly leaves Samsung for A6 production
Apple may drop Samsung and switch to Taiwan Semiconductor Manufacturing Company (TSMC) for the production of its next generation A6 chipset. The Cupertino Company is reportedly working with TSMC to move to a 28 nm ARM SoC in 2012. Rumors of this TSMC partnership surfaced earlier this year before Apple filed a trademark infringement suit against Samsung. Though the A4 and A5 are still being produced by Samsung, the Korean company may be out of the loop in future Apple hardware. This move away from Samsung may have a deleterious effect on the Korean manufacturer as Apple is reportedly one of its biggest customers. Apple has secured LCD displays, chipsets and NAND flash memory from Samsung that are used in its iOS devices. If the impending legal battle between the two companies sours the relationship, Apple may be forced to turn to costlier options for its device components, and Samsung may lose one of its biggest customers.
AMD confirms tablet-friendly Z-series APU, next-gen Trinity APU for bigger devices
AMD likes to take its time before stepping inside the ring, but it's turned up at Computex with its gown off and mouthguard in. Its much-leaked Z-series Fusion APU (aka "Desna") for tablet devices is now official and could well steal some of ARM's thunder. Whereas ARM chips will get along with the next version of Windows, AMD's Z-series is already tuned into the here-and-now. Its integrated dual 1Ghz Bobcat chips and Radeon HD 6250 graphics should allow the full Windows 7 experience on a tablet, from USB peripheral compatibility right down to XBOX 360 Media Extender functionality. What's more, it drinks less than 6W of power so is significantly leaner than the 9W Ontario APU powering Acer's Iconia W500 Windows 7 tablet. Additionally, AMD claims MSI has already made that leap with its new WindPad 110w (though we can't be sure if the pre-release device we just handled was carrying a Z-series chip). Meanwhile, AMD left any traces of shyness far behind as it went on to confirm plans for a range of A-series and E-series chips with which it hopes to tackle Intel's dominance in the laptop and desktop spheres -- right up to the level of the Core i7. This includes the leaked high-end quad-core A8 and, more surprisingly, a new Trinity APU. Looking way into the future, AMD intends Trinity to be a successor to the mid-range A-series Llano, which isn't even out yet but is expected imminently. Unfortunately we have no concrete specs for the Trinity -- AMD thought it was sufficient to wave the thing around at the press conference and declare it "2012's best APU". Depending on how you look at it, that's either fighting talk or plain posturing.
Next-next-gen Atom will be a system on a chip called 'Silvermont,' pack 3D transistors?
Last week, we were treated to an earful about Intel's plans for its future chips -- most notably, that it's committing to 3D transistors across the board. Well, that trickle of information hasn't run dry just yet -- today's tidbit gives us a peek not into the next-generation of Atom, but the one already in the works to come after that. The new processor, codenamed "Silvermont," will be a system-on-a-chip and is reportedly slated to ship sometime in 2013. CNET also cites unnamed sources who claim that it will be designed specifically to take advantage of Intel's 22nm technology and 3D transistors. As it stands, though, they boost the cost of wafers by two to three percent, so here's hoping that premium comes down before the netbooks of the future hit the market -- if we have netbooks in the future.
NVIDIA acquiring wireless chip manufacturer Icera, doubling-down on the post-PC era
NVIDIA, a company once focused entirely on giant graphics cards for home computers, has already quite successfully re-positioned itself as a player in the mobile graphics world. Now it's poised to really shake things up, announcing the acquisition of Icera. The UK-based company you've probably never heard of has a line of 3G and 4G baseband processors used in wireless devices and USB modems -- chips that are said to be smaller, more flexible, and more efficient than the competition from Qualcomm and ST-Ericsson. Icera seems to have been focused heavily on LTE of late, which puts NVIDIA in a good place to not only manage what happens to the data when its inside your next-gen phone or tablet, but to also control just how it gets there in the first place. A future Tegra SoC that handles wireless data too? Color us intrigued.
Marvell unveils Avastar 88W8797, first wireless SoC for mobile devices with 2x2 MIMO
The days of the shotgun modem live on with MIMO -- multiple-input and multiple-output adapters that offer numerous antennas to aggregate numerous parallel connections. Marvell just became the first to put such a solution on a tiny SoC, debuting its Avastar 88W8797 with dual 802.11n connectivity for transmission and receiving. This allows for 300Mbps transfers along with Bluetooth 4.0 and even FM transmission and reception, all built into a single chip with "advanced power management designed specifically for handheld products such as smartphones and tablets." You know what that means: shotgun WiFi in next-gen mobile devices. Yee haw!
