AMD Launches New Mobile APU Lineup, Kabini Gets Tested 35

Posted by timothy
from the failure-to-overwhelm dept.
An anonymous reader writes "While everyone was glued to the Xbox One announcement, Nvidia GeForce GTX 780 launch", and Intel's pre-Haswell frenzy, it seems that AMD's launch was overlooked. On Wednesday, AMD launched it's latest line of mobile APUs, codenamed Temash, Kabini, and Richland. Temash is targeted towards smaller touchscreen-based devices such as tablets and the various Windows 8 hybrid devices, and comes in dual-core A4 and A6 flavors. Kabini chips are intended for the low-end notebook market, and come in quad-core A4 and A6 models along with a dual-core E2. Richland includes quad-core A8 and A10 models, and is meant for higher-end notebooks — MSI is already on-board for the A10-5750M in their GX series of gaming notebooks . All three new APUs feature AMD HD 8000-series graphics. Tom's Hardware got a prototype notebook featuring the new quad-core A4-5000 with Radeon HD 8300 graphics, and benchmarked it versus a Pentium B960-based Acer Aspire V3 and a Core-i3-based HP Pavillion Sleekbook 15. While Kabini proves more efficient, and features more powerful graphics than the Pentium, it comes up short in CPU-heavy tasks. What's more, the Core-i3 matches the A4-5000 in power efficiency while its HD 4000 graphics completely outpace the APU."

BeagleBone Black Ships With New Linux 3.8 Kernel 35

Posted by timothy
from the add-cheap-monitor-wham-computer dept.
DeviceGuru writes "BeagleBoard.org has begun shipping its faster, cheaper BeagleBone Black SBC with a new Linux 3.8 kernel, supporting Device Tree technology for more streamlined ARM development. The $45 BeagleBone Black runs Linux or Android on a 1GHz TI Sitara AM3359 SOC, doubles the RAM to 512MB of its predecessor, and adds a micro-HDMI port. The updated kernel gives the BeagleBone Black access to a new Direct Rendering Manager (DRM) display driver architecture, as well as full support for the Device Tree data structure introduced to streamline ARM development in Linux 3.7. The project was hesitant to move up to such a recent kernel, but decided it was time to bite the bullet and support the Device Tree. By doing the hard work of switching to Device Tree now, BeagleBoard.org and its developer community can save a lot of configuration and maintenance headaches down the line, says BeagleBoard.org co-founder Jason Kridner. Fortunately, a modified 3.2 kernel 'coming soon' should provide the necessary bridge from the old cape driver architecture to the new one."

Intel Claims Haswell Architecture Offers 50% Longer Battery Life vs. Ivy Bridge 108

Posted by Soulskill
from the just-don't-use-a-screen-or-any-other-hardware dept.
MojoKid writes "As with any major CPU microarchitecture launch, one can expect the usual 10~15% performance gains, but Intel apparently has put its efficiency focus into overdrive. Haswell should provide 2x the graphics performance, and it's designed to be as power efficient as possible. In addition, the company has further gone on to state that Haswell should enable a 50% battery-life increase over last year's Ivy Bridge. There are a couple of reasons why Haswell is so energy-efficient versus the previous generation, but the major reason is moving the CPU voltage regulator off of the motherboard and into the CPU package, creating a Fully Integrated Voltage Regulator, or FIVR. This is a far more efficient design and with the use of 'enhanced' tri-gate transistors, current leakage has been reduced by about 2x — 3x versus Ivy Bridge."

A Cold Look at Cold Fusion Claims: Why E-Cat Looks Like a Hoax 394

Posted by timothy
from the judas-gets-too-little-credit dept.
In the past few days, several readers have submitted word of a paper published on Arxiv allegedly confirming the efficacy of Andrea Rossi's "E-Cat," a device Rossi says transmutes nickel into copper, producing cheap energy in the process. (Mentioned before on Slashdot.) Ethan Siegel of ScienceBlogs takes a skeptical look at the buzz surrounding this paper, and asks some seemingly obvious questions, pointing out various ways in which the cold-fusion / cheap-energy claims could be either confirmed or debunked. First time accepted submitter CdXiminez writes with a capsule of Siegel's points: "What would it take to convince a reasonable observer that you've got a controlled nuclear reaction going on here? Things not shown in the earlier report: Show that nuclear transmutation has in fact taken place; Start the device operating by whatever means you want, then disconnect all external power to it, and allow it to run; Place a gamma-ray detector around the device; Accurately monitor the power drawn from all sources to the device at all times, while also monitoring the energy output from the device at all times."

NVIDIA GeForce GTX 780 Offers 2,304 Cores For $650 150

Posted by timothy
from the that's-a-lot-of-grande-lattes dept.
Vigile writes "When NVIDIA released the GTX Titan in February, it was the first consumer graphics card to use the GK110 GPU from NVIDIA that included 2,688 CUDA cores / shaders and an impressive 6GB of GDDR5 frame buffer. However, it also had a $1000 price tag that was the limiting specification for most gamers. With today's release of the GeForce GTX 780 they are hoping to utilize more of the GK110 silicon they are getting from TSMC while offering a lower cost version with performance within spitting range. The GTX 780 uses the same chip but disables a handful more compute units to bring the shader count down to 2,304 — still an impressive bump over the 1,536 of the GTX 680. The 384-bit memory bus remains though the frame buffer is cut in half to 3GB. Overall, the performance of the new card sits squarely between the GTX Titan ($1000) and AMD's Radeon HD 7970 GHz Edition ($439), just like its price. The question is, are PC gamers willing to shell out $220+ dollars MORE than the HD 7970 for somewhere in the range of 15-25% more performance?" As you might guess, there's similarly spec-laden coverage at lots of other sites, including Tom's, ExtremeTech, and TechReport. HotHardware, too.

First Government Lawsuit Against a Patent Troll 96

Posted by samzenpus
from the when-the-man-comes-around dept.
walterbyrd writes "Late last year, a vigorous and secretive patent troll began sending out thousands of letters to small businesses all around the country, insisting that they owed between $900 and $1,200 per worker just for using scanners. The brazen patent-trolling scheme, carried out by a company called MPHJ technologies and dozens of shell companies with six-letter names, has caught the attention of politicians. MPHJ and its principals may have gone too far. They're now the subject of a government lawsuit targeting patent trolling—the first ever such case. Vermont Attorney General William Sorrell has filed suit in his home state, saying that MPHJ is violating Vermont consumer-protection laws."

Will Robots Take Over the Data Center? 136

Posted by Unknown Lamer
from the screaming-in-digital dept.
1sockchuck writes "Robotics are beginning to be integrated into data center management, creating the potential for a fully automated, robot-driven data center. What might a robot-controlled 'lights-out' data center look like? The racks will be taller, as robotics systems can reach higher to manage servers. Robotic equipment would be mounted on rails that allow them to find and move hardware. Early examples of this are seen in tape libraries, but the concepts could be applied to other data center equipment. Amazon and Google are said to be among those looking at ways to create a fully automated data center. AOL says it has already built an unmanned data center. Data Center Knowledge looks at the challenges and opportunities in robot-controlled data centers, including how staff roles would evolve."

Congressional Report: US Power Grid Highly Vulnerable To Cyberattack 123

Posted by Soulskill
from the industry-strangely-averse-to-voluntary-protections dept.
An anonymous reader writes "Despite warnings that a cyberattack could cripple the nation's power supply, a U.S. Congressional report (PDF) finds that power companies' efforts to protect the power grid are insufficient. Attacks are apparently commonplace, with one utility claiming they fight off some 10,000 attempted attacks every month. The report also found that while most power companies are complying with mandatory standards for protection, few do much else above and beyond that to protect the grid. 'For example, NERC has established both mandatory standards and voluntary measures to protect against the computer worm known as Stuxnet. Of those that responded, 91% of IOUs [Investor-Owned Utilities], 83% of municipally- or cooperatively-owned utilities, and 80% of federal entities that own major pieces of the bulk power system reported compliance with the Stuxnet mandatory standards. By contrast, of those that responded to a separate question regarding compliance with voluntary Stuxnet measures, only 21% of IOUs, 44% of municipally- or cooperatively-owned utilities, and 62.5% of federal entities reported compliance.'"

Working Handgun Printed On a Sub-$2,000 3D Printer 519

Posted by timothy
from the liberator-lite dept.
Just a few weeks after Cody Wilson and friends successfully fired an instance of their own 3-D printed handgun design, Sparrowvsrevolution writes, "a couple of Wisconsin hobbyist gunsmiths have already managed to adapt Defense Distributed's so-called Liberator firearm and print it on a $1,725 Lulzbot 3D printer, a consumer grade machine that's far cheaper than the industrial quality Stratasys machine Defense Distributed used. They then proceeded to record their cheaper gun (dubbed the 'Lulz Liberator') firing nine .380 rounds without any signs of cracking or melting. Eight of the rounds were fired from a single plastic barrel. (Defense Distributed only fired one through its prototype.) In total, the Lulz Liberator's materials cost around $25 and were printed over just 48 hours."

riverat1 writes "After being embarrassed when the Europeans did a better job forecasting Sandy than the National Weather Service Congress allocated $25 million ($23.7 after sequestration) in the Sandy relief bill for upgrades to forecasting and supercomputer resources. The NWS announced that their main forecasting computer will be upgraded from the current 213 TeraFlops to 2,600 TFlops by fiscal year 2015, over a twelve-fold increase. The upgrade is expected to increase the horizontal grid scale by a factor of 3 allowing more precise forecasting of local features of weather. The some of the allocated funds will also be used to hire some contract scientists to improve the forecast model physics and enhance the collection and assimilation of data."

Ask Slashdot: Wiring Home Furniture? 235

b1tbkt writes "So it seems that furniture manufacturers have not yet acknowledged the realities of modern life. Kitchen tables could benefit greatly from built-in concealable receptacles. Even more obvious is the need for electrical wiring in couches and coffee tables. I realize that there are safety (fire) concerns but as it stands most families that I know already have power cords for laptops, tables and phones draped over, under and through their couches at any given point. If someone wanted to wire their furniture with AC or some type of standardized LV DC system, what are some dangers to watch for and what, if any, specialized hardware exists for the purpose?"

Google's Nexus Q Successor Hits the FCC 56

from the h-2-g-2-is-a-good-name dept.
With the kind of cagey phrasing found in many such electronics approval applications, Google describes a device that some are taking to be the successor to its discontinued Nexus Q thus: "The device functions as a media player." From the article: "Some of the specs of the device includes a 2.4GHz WiFi b/g/n connectivity. The FCC report does not contain test photos so we do not know what the device looks like. It is likely that the H840 will support Google Play Music All Access and will have similar functionality as a Sonos media player that can be connected to external speakers."

Charge Your Cellphone In 20 Seconds (Eventually) 295

Posted by timothy
from the drive-by-juicing dept.
New submitter GoJays writes "An 18-year-old from Saratoga, California has won an international science fair for creating an energy storage device that can be fully juiced in 20 to 30 seconds. The fast-charging device is a so-called supercapacitor, a gizmo that can pack a lot of energy into a tiny space, charges quickly and holds its charge for a long time. What's more, it can last for 10,000 charge-recharge cycles, compared with 1,000 cycles for conventional rechargeable batteries, according to the inventor Eesha Khare." This one in particular has been used so far only to power an LED, rather than a phone or laptop, but I hope in a few years near-instant charging of portable electronics will be the norm as supercapacitors grow more common.
