Intel details 14 dual-core Ivy Bridge processors ahead of Computex
Intel announced its quad-core Ivy Bridge processors in April, but we've known that dual-core CPUs must be on the way too. And alas, the chip maker does have some up its sleeve -- 14, to be exact. Core i5 and Core i7 versions will be the first to ship, with Core i3 processors launching later this year along with new Pentiums and Celerons. Of the 14 dual-core processors, six are desktop-grade. The rest are mobile, though four are ultra-low voltage (which will be denoted by a U at the end of their name). Computex is just around the corner, and we expect to see plenty of Ivy Bridge systems -- especially Ultrabooks with ultra-low voltage CPUs -- there next week. In the meantime, we've already reviewed the Lenovo ThinkPad x230, a system running a dual-core 2.6GHz Core i5 Ivy Bridge processor. If you're into the nitty-gritty details, you'll find plenty to love in the Intel slides below the break.
Researchers tout efficiency breakthrough with new 'inexact' chip
Accuracy is generally an important consideration in computer chips, but a team of researchers led by Rice University are touting a new "inexact" chip (dubbed PCMOS) that they say could lead to as much as a fifteen-fold increase in efficiency. Their latest work, which won a best paper award at a recent ACM conference, builds on years of research in the field from the university, and is already moving far beyond the lab -- some inexact hardware is being used in the "i-slate" educational tablet developed by the Rice-NTU Institute for Sustainable and Applied Infodynamics, 50,000 of which are expected to wind up in India's Mahabubnagar school district over the next three years. As for the chips themselves, their inexactness comes not just from one process, but a variety of different measures that can be used on their own or together -- including something the researchers describe as "pruning," which eliminate rarely used portions of the chip. All of that naturally comes with some trade-offs (less defined video processing is one example given), but the researchers say those are often outweighed by the benefits -- like cheaper, faster chips that require far less power.
Intel wants to have conflict-free processors by the end of 2013
Intel had already promised that it would avoid using conflict minerals, and now it's giving itself a more concrete timetable for that to happen. It wants to have at least one processor that's proven completely conflict-free across four key minerals -- gold, tantalum, tin and tungsten -- by the end of 2013. Lest you think Intel's not taking swift enough action, it wants to reach the tantalum goal by the end of this year. The effort's part of a wider array of goals that should cut back on the energy use, power and water use by 2020. Sooner rather than later, though, you'll be buying a late-generation Haswell- or Broadwell-based PC knowing that the chip inside was made under nobler conditions.
VIA unveils fanless, Eden X2-packing AMOS-3002, promises tiny dual-core PC in your car
VIA is planning to get some serious mileage out of its Eden X2 processor -- in the most literal sense possible. It's now producing the AMOS-3002, a Pico-ITX-sized PC intended for in-car infotainment and other situations where an embedded PC needs to have a little more juice for media tasks. The Eden X2 in question comes in a dual-core 1GHz flavor that's completely fanless, but it's fast enough to show 1080p video (when your car is parked, we hope) and can handle more intensive work like dual gigabit Ethernet jacks, optional 3G and even a 2.5-inch hard drive. That breadbox-sized shell can also take a lot of abuse, surviving temperatures between -4F and 140F as well as 50 Gs' worth of shock. You'll have to wait until your favorite car designer or digital sign maker uses the AMOS-3002 to see it in action, but until then, you can get the full details after the break.
Intel sets sights on 5nm chip; already gearing up fabs for 14nm production
Ivy Bridge, Intel's first generation of chips to use the 22nm fabrication process, is hardly out of the gate, and yet talk has already turned to the company's next manufacturing technologies. According to Xbit Labs, which got its hands on some telltale slides, Paul Otellini et al. have the roadmap for 10nm, 7nm and 5nm processes locked down, and the company is preparing fabs in the states and Ireland to make chips using the 14nm fabrication method. Given that timeframe, Intel says 10nm chips will ship in 2015, with work on 5nm technology beginning that same year. While the slides in question look legit -- and that timeline matches previous reports -- we're not sure just when these mystery slides first made the rounds. Alas, we'll have a good few years to sort 5nm fact from fiction.
Origin PC upgrading pre-Ivy Bridge orders with new silicon, asking nothing in return
Sure, you may need to shop around to find a replacement for that 11-inch number Dell pulled off the shelves, but that doesn't mean you need to miss out on a free Ivy Bridge upgrade. Origin PC tells us that it's offering the very same silicon swap as Dell to folks who pulled the trigger on any of its laptop and desktop PCs before Intel's big launch. If your order hasn't shipped yet, you're looking at an upgrade. Now if only we could find a manufacturer willing to hand out free GPU upgrades.
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.
TSMC ramps 28nm ARM Cortex-A9 chip to 3.1GHz, gives your desktop jitters
We know TSMC's energy-miser 28-nanometer manufacturing process has a lot of headroom, but the company just ratcheted expectations up by a few notches. Lab workers at Taiwan's semiconductor giant have successfully run a dual-core ARM Cortex-A9 processor at 3.1GHz under normal conditions. That's a 55 percent higher clock speed than the 2GHz maximum that TSMC normally offers, folks, and about twice as fast as a 40nm chip under the same workload. Don't expect that kind of clock speed from your next smartphone or tablet, though: expect processors of this caliber to find "high-performance uses," which takes us that much closer to NVIDIA's Project Denver as well as other ARM-based desktops, notebooks and servers that should give x86 chips a run for their money.
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.
New Intel Ivy Bridge i5 details leaked in Intel sales book
Word on the street is Ivy Bridge has been delayed, but that doesn't mean you have to wait till June to get the low down on some of the shiny new silicon Intel has in store for you. Chipzilla posted a sales book, presumably on accident since it's been pulled, with details about upcoming i5 and i7 refreshes. The only page we were able to find was loaded with Core i5s, including third generation parts like the 3.4GHz 3570K which packs the new HD4000 and, most likely, an unlocked multiplier. Most of the rest of the lineup, save the 3475S, is rocking Intel's HD2500 IGP, while the lone dual-core part is the 3470T, which is also the only chip to sport Hyper-Threading and ship with only 3MB of cache. Now, as far as when you can buy these processors or how much they'll cost, we're still in dark, but at least we've got a better idea of what we'll be shopping for. Head on after the break for a slightly better look at the new parts.
Intel reportedly delays Ivy Bridge launch until June, manufacturing process to blame
Looking forward to splurging for some tech decked out with Ivy Bridge? Well, you may have to wait a bit longer. Financial Times is reporting that Intel's new 22nm processor has been pushed from April to June. The site caught up with executive VP and chairman of Intel China Sean Maloney who said that the manufacturing methods used to make the heir to Sandy Bridge was to blame for the change in schedule. Furthermore, a spokesperson for the component manufacturer communicated that the Q2 shipping plans for Ivy Bridge remain the same. You can rest assured we'll be keeping a close watch on this one and what the delay could mean for upcoming laptop releases.
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.
AMD reports a net loss for Q4 2011, 30 million APUs sold last year
As the quarterly earnings train rolls along, AMD has announced its results for the last three months of 2011, with weaker than expected sales resulting in a net loss of $177 million on revenue of $1.69 billion. Worse, ZDNet mentions AMD expects revenue to continue to decline as 2012 gets started. Of course, there were highlights including sales of more than 30 million Accelerated Processor Units (APU) for the year, resulting in record annual notebook revenue, while CEO Rory Read also noted "re-gained momentum" in its server business. AMD's revenue remained flat YoY at $6.57 billion, but that and all the other dirty financial details are in the press release after the break. For 2012 Read says AMD is "clear on our priorities and opportunities", we'll see if those newly focused initiatives add up to a better result at this time next year.
Intel starts shipping Atom N2600, N2800 processors for netbooks, ten hours of battery life promised
We've already seen a few benchmarks and other hints that they'd soon be shipping, and Intel has now officially announced that its new Cedar Trail Atom processors are finally available, with the first systems using them set to roll out early next year. The two chips you'll likely be seeing the most of are the Atom N2600 and N2800 -- both dual-core, and both designed for use in netbooks, where they promise to allow for up to ten hours of battery life and "weeks of standby," and offer support for 1080p video playback. Also rolling out today are the D2500 and D2700, which are designed for use in entry-level desktops and all-in-one computers, as well as more commercial systems. As for all those systems themselves, details remain a bit light, but Intel says you can expect to see some from Acer, Asus, HP, Lenovo, Samsung, and Toshiba.
NTT Docomo, Panasonic, Samsung and more team up to take on Qualcomm over cellphone chips
Japanese mobile operator NTT Docomo just announced (as had been rumored) it's forming a joint venture with five partners -- Samsung, Panasonic, Fujitsu Limited, Fujitsu Semiconductor and NEC -- to develop and sell chips for mobile devices. According to the press release the fabless JV will get started once all involved finish hammering out the details and focus on creating LTE-connected products for the global market. NTT Docomo is investing $5.8 million to create a subsidiary, Communication Platform Planning Co., in preparation with one of its executives as CEO. Currently Qualcomm makes the majority of chips found in smartphones, but it appears to have some high-powered competition on the way soon.
AMD updates A-Series APUs, gives laptop Llanos modest spec bumps
AMD released its A-Series APUs almost six months ago, and since then it's seen Intel update the A-Series' Sandy Bridge counterparts. So, it's about time for the Llano laptop lineup to do the same, and the refresh has come in the form of seven spiffy new APUs. At the high end, there's the quad-core A8-3550MX clocked at 2.0 GHz with Radeon HD 6620G graphics to supplant the older A8-3530MX chip. On the low end, the 1.9GHz dual core A4-3305M with Radeon HD 6480G graphics joins AMD's A4-3300M. It's a minor update all around, with most models seeing a 100MHz boost in turbo frequency over existing A-Series APUs. If you're itching to dig a little deeper into all the fresh Fusion silicon, you'll find what you're looking for at the links below.
IBM sees stacked silicon sitting in fluid as the way to power future PCs
Generally, the combination of microchips, electricity and fluids is usually considered an incredibly bad thing. IBM, however, thinks it can combine those three to make super small and super powerful computers in the future. The idea is to stack hundreds of silicon wafers and utilize dual fluidic networks between them to create 3D processors. In such a setup, one network carries in charged fluid to power the chip, while the second carries away the same fluid after it has picked up heat from the active transistors. Of course, 3D chips are already on the way, and liquid cooled components are nothing new, but powering a PC by fluids instead of wires has never been done before. Bruno Michel, who's leading Big Blue's research team, has high hopes for the technology, because future processors will need the extra cooling and reduced power consumption it can provide. Michel says he and his colleagues have demonstrated that it's possible to use a liquid to transfer power via a network of fluidic channels, and they to plan build a working prototype chip by 2014. If successful, your smartphone could eventually contain the power of the Watson supercomputer. Chop, chop, fellas, those futuristic fluidic networks aren't going to build themselves.
AMD to cut workforce by 10 percent, invest savings in emerging markets and the cloud
After hitting a speed bump Q2 and making a modest bounce back in Q3, AMD doesn't seem to want to take any chances with Q4: the CPU firm just announced it's optimizing its cost structure to "enhance competitiveness and accelerate growth." In a press release, the outfit stated that it expects to save $10 million in the fourth quarter by cutting its global workforce by 10 percent and killing off a few contractual commitments. AMD says that the workforce reduction is global, and reaches all divisions of the company -- giving employees everywhere an excuse to rattle their boots. Combined with an efficiency heavy restructuring plan, the outfit predicts that the employee reduction will save more than $200 million in operational savings in 2012. AMD says it plans to reinvest a significant helping of the savings in projects targeting lower power, emerging markets and the cloud. Hit the press release after the break for official numbers and restructuring riffraff.
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 joins ARM A5 and M4 cores at the hip for performance and power savings
You may have noticed a trend recently -- pairing slightly less powerful cores that sip power, with more robust ones that can chug through demanding applications. NVIDIA's Tegra 3 will be packing an underclocked fifth core, while ARM's big.LITTLE initiative matches a highly efficient 28nm A7 with the beefy A15. Now Freescale is planning to use the same trick, but you won't find its asymmetrical CPUs in your next tablet or smartphone. Its platform, which marries a Cortex M4 to a Cortex A5, isn't meant to compete with the latest Snapdragon. These chips will find homes in factories and in-dash infotainment systems which have increasingly sophisticated UIs, but don't need to push thousands of polygons. Software development tools will land before this quarter is out and the first batch of silicon will be announced in Q1 of 2012. Looks like the era of "dual-core" meaning two identical cores has officially come to an end.
