Samsung reveals high-end, low-power chips for midrange phones
Samsung has announced that it's bringing its 14nm Exynos chips to cheaper smartphones. These are smaller chips that are both more efficient and more powerful, and given that the company is already putting the technology to use on competitors' chips (namely, Qualcomm's), it's no surprise to see the chip appear in more phones. Until now, Samsung's only put the FinFET-made (that's 3D-structured) 14nm processors in its best -- and most expensive -- phones. That's about to change.
AMD's new CEO has a background in mobile technology
It feels like just yesterday that AMD brought in Rory Read to turn around its ailing fortunes, but today there's another changing of the guard. The chip designer has announced that chief operating officer Lisa Su is its new CEO, effective immediately; Read will stick around as an advisor until the end of the year. The company isn't going into detail about the reasons behind the shift, but it does say that Read has been planning a succession with the board of directors. It's an "ideal time" for Su to take the reins, the board's Bruce Clafin says.
Intel plots a mobile coup with $1.5 billion investment in Chinese chipmakers
While Intel is prominent in the mobile world, it's often playing catch-up with the undisputed king of the market, ARM (and as a result, Qualcomm). But that doesn't mean it's not willing to spend money to reverse that trend. The company has announced that it's paid $1.5 billion for a 20 percent share in two of China's biggest mobile chipmakers, Spreadtrum Communications and RDA Microelectronics. The deal will see Spreadtrum jointly create and sell a range of Intel-based system-on-chips (SoCs), which Intel says will power devices from the middle of next year. It gives Intel the boost it needs to begin competing against its more established rivals, but also offers the chance of cracking the world's biggest smartphone market (where Qualcomm is currently facing an antitrust probe). While Spreadtrum is known for low-cost chips that power Mozilla's Firefox OS smartphones, there's every chance this deal could see Intel make more of a splash in the booming Android market.
Intel details Z3000 Bay Trail chips for tablets and hybrids, claims up to 2x CPU and 3x GPU performance
Intel barely existed on the mobile scene two years ago, and yet the company's Clover Trail chips for low-power tablets and hybrids have already had a huge impact on the Windows PC market -- not least by rendering Windows for ARM (aka Windows RT) largely redundant. But Clover Trail's performance in devices like the Acer Iconia W3 or Lenovo IdeaTab Lynx is far from perfect, especially with Windows 8 desktop applications and anything that involves 3D graphics, and that's why we're more than ready for its successor: Bay Trail, which is based on the next-generation 22nm Silvermont architecture. Intel has today detailed three families of Bay Trail chips, the most interesting of which is undoubtedly the Z3000-series for tablet form factors, and you can catch up on these new SoCs right after the break.
Qualcomm's Anand Chandrasekher says eight-core processors are 'dumb'
In response to a question about whether Qualcomm will create an eight-core processor like MediaTek's upcoming model, Senior VP Anand Chandrasekher told a Taiwanese publication "we don't do dumb things." He added that "you can't take eight lawnmower engines, put them together and now claim you have an eight-cylinder Ferrari." Instead, he said Qualcomm is focused on good modems, long battery life and affordability, rather than "simply throwing cores together." Though MediaTek had no comment on that, it claimed earlier that all eight cores in its upcoming CPU can operate at the same time to improve stability and battery life -- unlike the Exynos 5's big.LITTLE configuration, for instance. Whether you agree with Chandrasekher or not, eight seems better than four, meaning most CPU outfits -- including Qualcomm -- will likely jump on the octa-core bandwagon.
AMD's Opteron X-series targets Intel Atom for the microserver CPU market
AMD might not be able to keep up (down?) with Intel in the CPU power consumption race, so it's taking another tack with the new Opteron X-series: horsepower. It just announced the Opteron X1150 and X2150 64-bit processors for microservers, part of the Jaguar-codenamed family of CPUs arriving in the next-gen Xbox One and Sony PS4 consoles. Thanks to its ultra-low power 6-watt Atom S1200 chips, Intel excels in the low-power server market, and at 9W and 11W respectively (minimum), AMD's CPUs consume considerably more juice. But AMD is pitching them as a better solution overall, thanks to those four cores (compared to two in the Atom), integrated AMD Radeon HD 8000 graphics on the X2150 model, support for 32GB of RAM and integrated SATA ports. AMD's chips are pricier, though, at $64 (X1150) or $99 (X2150) compared to $54 for Intel's Atom S1200 (all in quantities of 1,000). To top it off, Intel has new 64-bit Atom SoCs coming soon promising even lower power consumption -- possibly leaving AMD to play catch-up again.
CES 2013: PC and processor roundup
The most hyped tech news isn't always the most important. Having had a few days to dwell on what CES 2013 meant for computing, and for mobile computing in particular, we've settled on some less-than-obvious highlights. So, if you'd like to know how Intel stole the show but not our hearts; how Qualcomm's weird keynote was overshadowed by a late, secondary announcement from Samsung; and how some of the most exciting PC trends were mainly conspicuous by their absence, then please read on. It'll be like juice with bits, but only the bits that matter.
Apple reportedly makes a deal with TSMC for A6X production
With absolutely no love lost between Apple and Samsung, it's being suggested that Apple will yank processor chip production from the South Korean tech giant. A report today in the Mac Observer, quoting from The Commercial Times translated by AFP says Taiwan Semiconductor Manufacturing Company (TSMC) will become the major supplier of chips for Apple's mobile devices. That change could happen as early as the first quarter of this year. Apple designs its own processors but gives contracts to others to produce them. Given the swarm of lawsuits between Samsung and Apple, it seemed only a matter of time before Apple pulled the plug, and certainly saw no reason to award multi-million dollar contracts to a company Apple feels has ripped off many of its ideas. In August, Samsung was ordered by a US court to pay Apple US$1.05 billion in damages for copying the iPhone and iPad features in some Galaxy smartphones. Samsung is appealing the ruling. Apple and TSMC have declined to comment on the report.
Allwinner throws A20 dual-core and A31-quad-core processors into ARM fray
Whimsically monikered Chinese chip-maker Allwinner has added a pair of ARM Cortex-A7 processors to its lineup supporting Android 4.2 or higher systems. The A20 is a dual-core design with 512KB L2 cache, dual-core Mali 400 graphics and 2160p HD video playback support, while the quad-core A31 packs a 1MB cache, PowerVR SGX 544 graphics and UHDTV (4k) video decoding talents. The A20 is pin compatible with its Linux-hobbyist favorite sibling, the A10 -- meaning devices such as the MK802 mini-PC using that chip could likely be upgraded by manufacturers on the cheap. However, the more powerful A31 seems destined for higher-end Android or Windows RT devices only, considering its beefier PowerVR graphics. On top of the extra zip, licensor Imagination Technologies keeps its source code cards close to the chest -- likely ruling out Linux for that chip.
AMD shutters key Linux support lab in Germany as part of company-wide layoffs
The pain from recently announced job cuts by AMD could ripple out to the Linux community, as the chipmaker has shut down a small but important Linux OS research facility in Dresden, Germany. The center housed 25 employees who helped port AMD technology like PowerNow over to new Linux distros, and according to The H, many engineers who submitted major processor and chipset revisions for the OS would be pink slipped. The closure won't affect GPU and APU development, according to the source, but it's not yet known exactly who will pick up the slack from the former Dresden team -- though the research center in Austin Texas is reported to be a likely bet.
AMD promises 64-bit ARM-based Opteron server CPUs coming in 2014
AMD has long stuck to x86 architecture for its server processors, but its gearing up to add 64-bit ARM-based Opteron CPUs to its arsenal in 2014. Sunnyvale also plans to reap the fruits of its SeaMicro acquisition by employing the company's "fabric" tech to link its ARM-based processors in clusters for maximizing efficiency. Where might these new processors come in handy? AMD thinks they'll fit nicely into clouds and "mega data centers" thanks to their power efficiency, but it'll let its x86-based hardware do the heavier lifting such as video encoding and rendering. Other details on the CPUs are scarce, but we suspect that'll change as 2014 approaches.
Intel roadmap reveals 10-core Xeon E5-2600 V2 Ivy Bridge CPU
Intel may have recently spilled its Q3 guts for 2012, but we highly doubt that the chip maker planned on outing its forthcoming projects for next year. An alleged internal slide makes the claim that the silicon giant plans to introduce a 10-core Xeon E5-2600 V2 Ivy Bridge-EP CPU in the third quarter of 2013. Compatible with Socket R LGA 2011 motherboards, this brute will max out at 20 threads through HyperThreading. Packing 30MB of L3 cache, this unannounced Ivy Bridge supports up to 1866MHz of DDR3 system RAM. If these specifications have whet your appetite, the Xeon E5-2600 V2 is only the tip of the iceberg -- Chipzilla is said to also have a 12-core processor in the pipeline as well.
Qualcomm reveals quad-core Snapdragon S4 Play processors, ramps up entry smartphone speeds
Don't think Qualcomm is limiting its quad-core processors to superstar phones. The Snapdragon S4 Play line is growing to include the MSM8225Q and MSM8625Q, parallels to the existing two Play chips that bring four cores to entry-level devices. Besides the speed improvements that you'd expect from all that extra parallelism, the Q variants support the extra bandwidth of low-power DDR2 (LPDDR2) memory and can handle both 720p displays and movie-making. Neither is quite an all-encompassing solution, although the two will cover the bases for much of the starter demographic: while local wireless such as Bluetooth, FM radio and WiFi have to remain separate from the main processor, the two newcomers manage to pack either single-mode UMTS 3G (in the 8225Q) or dual-mode CDMA and UMTS (in the 8625Q) for their cellular fix. Along with the already promised, China-focused S4 Plus MSM8930, test samples of the faster S4 Play editions will be ready before the end of the year, with shipping phones on the way in early 2013 -- just in time to go head-to-head with a similar push by MediaTek to make quad-core the norm for a much larger slice of the population.
Globalfoundries unveils 14nm-XM chip architecture, vows up to a 60 percent jump in battery life
Globalfoundries wants to show that it can play the 3D transistor game as well as Intel. Its newly unveiled 14nm-XM (Extreme Mobility) modular architecture uses the inherently low-voltage, low-leak nature of the foundry's FinFET layout, along with a few traces of its still-in-development 20nm process, to build a 14-nanometer chip with all the size and power savings that usually come from a die shrink. Compared to the larger processors with flat transistors that we're used to, the new technique is poised to offer between 40 to 60 percent better battery life, all else being equal -- a huge help when even those devices built on a 28nm Snapdragon S4 can struggle to make it through a full day on a charge. To no one's shock, Globalfoundries is focusing its energy on getting 14nm-XM into the ARM-based processors that could use the energy savings the most. It will be some time before you find that extra-dimensional technology sitting in your phone or tablet, though. Just as Intel doesn't expect to reach those miniscule sizes until 2013, Globalfoundries expects its first working 14nm silicon to arrive the same year. That could leave a long wait between test production runs and having a finished product in your hands.
Intel finishes crossing the Ivy Bridge with new desktop Core i3 models
Intel has been staggering the rollout of its Ivy Bridge processors over the space of nearly half a year, starting with its higher-end quad-core chips; it's finally time for the company to complete the story and ship some budget Core i3 desktop parts. The semiconductor giant is coy about the new roster at this stage, but it does promise both regular (s-series) and low-power (t-series) Core i3 chips at clock speeds between 2.8GHz and 3.4GHz. If the past is an indicator, the new components will be mostly or exclusively dual-core and lack extras like Hyperthreading -- they will get Intel's newer integrated graphics and other perks through the upgrade, however. Bulk pricing and other details haven't yet been aggregated in one place, although we're seeing that even the faster 3.3GHz Core i3-3220 is selling at retail for $130. We wouldn't expect anything from Intel's new offerings to break the bank.
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.
AMD FX-4130 delivers 3.8GHz quad-core on a budget, A-Series chips get even cheaper
If you're building a starter desktop to get ready for school, you'll be glad to know that AMD is squeaking just a little more value for the dollar out of its processors. The new quad-core FX-4130 takes a 200MHz hop forward from its predecessor to a 3.8GHz base speed, and ramps up to 3.9GHz if it's feeling frisky. While it's thirstier than the earlier FX-4100 at 125W of maximum power draw, the unlocked chip's $112 retail cost is a potential sweet spot for those tailoring a system to a strict price. Anyone willing to trade overclocking support for yet more of a savings will be glad to know that AMD has been slashing the prices of its Fusion-based A-Series chips at the same time: the across-the-board cuts bring even the 2.9GHz A8-3850 down to $91. No breaks exist here for the performance crowd, alas, but AMD's new proposition might be just the excuse needed to build that budget Windows 8 PC.
IBM creates consistent electron spin inside semiconductors, takes spintronics one twirl closer
A fundamental challenge of developing spintronics, or computing where the rotation of electrons carries instructions and other data rather than the charge, has been getting the electrons to spin for long enough to shuttle data to its destination in the first place. IBM and ETH Zurich claim to be the first achieving that feat by getting the electrons to dance to the same tune. Basing a semiconductor material on gallium arsenide and bringing the temperature to an extremely low -387F, the research duo have created a persistent spin helix that keeps the spin going for the 1.1 nanoseconds it would take a normal 1GHz processor to run through its full cycle, or 30 times longer than before. As impressive as it can be to stretch atomic physics that far, just remember that the theory is some distance from practice: unless you're really keen on running a computer at temperatures just a few hops away from absolute zero, there's work to be done on producing transistors (let alone processors) that safely run in the climate of the family den. Assuming that's within the realm of possibility, though, we could eventually see computers that wring much more performance per watt out of one of the most basic elements of nature.
IBM pushing System z, Power7+ chips as high as 5.5GHz, mainframes get mightier
Ten-core, 2.4GHz Xeons? Pshaw. IBM is used to the kind of clock speeds and brute force power that lead to Europe-dominating supercomputers. Big Blue has no intentions of letting its guard down when it unveils its next generation processors at the upcoming Hot Chips conference: the company is teasing that the "zNext" chip at the heart of a future System z mainframe will ramp up to 5.5GHz -- that's faster than the still-speedy 5.2GHz z196 that has led IBM's pack since 2010. For those who don't need quite that big a sledgehammer, the technology veteran is hinting that its upcoming Power7+ processors will be up to 20 percent faster than the long-serving Power7, whose current 4.14GHz peak clock rate may seem quaint. We'll know just how much those extra cycles mean when IBM takes to the conference podium on August 29th, but it's safe to say that our databases and large-scale simulations won't know what hit them.
Engadget Primed: why nanometers matter (and why they often don't)
Primed goes in-depth on the technobabble you hear on Engadget every day -- we dig deep into each topic's history and how it benefits our lives. You can follow the series here. Looking to suggest a piece of technology for us to break down? Drop us a line at primed *at* engadget *dawt* com. Welcome to one of the most unnecessarily complicated questions in the world of silicon-controlled gadgets: should a savvy customer care about the underlying nature of the processor in their next purchase? Theoretically at least, the answer is obvious. Whether it's a CPU, graphics card, smartphone or tricorder, it'll always receive the Holy Grail combo of greater performance and reduced power consumption if it's built around a chip with a smaller fabrication process. That's because, as transistors get tinier and more tightly packed, electrons don't have to travel so far when moving between them -- saving both time and energy. In other words, a phone with a 28-nanometer (nm) processor ought to be fundamentally superior to one with a 45nm chip, and a PC running on silicon with features etched at 22nm should deliver more performance-per-watt than a 32nm rival. But if that's true, isn't it equally sensible to focus on the end results? Instead of getting bogged down in semiconductor theory, we may as well let Moore's Law churn away in the background while we judge products based on their overall user experience. Wouldn't that make for an easier life? Well, maybe, but whichever way you look at it, it's hard to stop this subject descending into pure philosophy, on a par with other yawnsome puzzles like whether meat-eaters should visit an abattoir at least once, or whether it's better to medicate the ailment or the person. Bearing that in mind, we're going to look at how some key players in the silicon industry treat this topic, and we'll try to deliver some practical, offal-free information in the process.
