Just in case laying claim as the fastest single-GPU videocard on the planet wasn't enough of a selling point for AMD's recently released HD 5870 videocard, Asus has added a twist that it claims will boost performance by up to 38 percent: Voltage Tweak Technology.
According to Asus, owners of its newly launched EAH5870/2DIS/1GD5 and EAH5850/2DIS/1GD5 videocards will be able to crank up GPU voltages through its SmartDoctor application. On the HD 5870, end users can raise the volts from 1.15V to 1.35V, boosting GPU and memory clockspeeds from 850MHz and 4800MHz (effective) to 1035Mhz and 5200MHz. On the HD 5850, gamers can up the volts from 1.088V to 1.4V, which is enough to overclock the GPU and memory from 725MHz and 4000MHz to 1050MHz and 5200MHz.
By doing so, Asus' own benchmarking noted a 17 percent performance gain in 3DMark Vantage Extreme on the 5870, and an impressive 38 percent jump on the 5850.
The folks over at the University of Utah are working on using wireless networking equipment to see through walls. Yep, they are trying to turn your wifi network into an investigative x-ray machine.
Well, it is slightly more complicated than that. They set up a 34-node wireless network and used principals similar to sonar to aggregate the movement of objects behind physical objects. You can practically hear the excitement from all the spy-happy teenagers. Joey Wilson and Neal Patwari’s intentions were much more altruistic.
Obviously, privacy is a concern. But let’s face it, you’ve got nothing to hide so long as you aren’t a terrorist, hostage wrangler, or scantily clad getting out of the shower.
More details about why they did it after the jump.
Streaming boxes are a mixed bag these days. With super-polished commercial offerings like the AppleTV, as well as streaming functionality integrated in every other consumer electronics device—from the Xbox 360 to the TiVo—we thought the age of the dedicated streaming box had passed. However, the SageTV HD Theater offers something a little different than the typical UPNP or DLNA streaming box—but it’ll cost you.
Starting with the additional $80 for SageTV’s Media Center app, which should be a requirement for using the HD Theater. If you install the SageTV software on a PC equipped with an HDTV card, it turns that PC into a fully functional PVR, complete with an onscreen guide and basic scheduling functionality. SageTV’s Media Center is an acceptable PVR, offering more customizability than Windows Media Center and none of its annoying DRM, albeit in a less-polished product. The software’s 10-foot interface is incredibly customizable, but can be a little unwieldy and slow to browse, even when run on a fast PC.
Like that cold you can't seem to shake, DDR2 has been hanging onto the market place, even as new platforms make a push for DDR3. That all changes six months from now, as DDR3 finally becomes the mainstream memory, says Morgan Stanley analyst Frank Wang.
Samsung, Hynix, Elpida, and Micron have all started to reshuffle manufacturing to allocate more capacity to DDR3 output, and of course that means scaling down DDR2 parts. And for those who are unable to produce DDR3 chips, they will be forced to pack their bags and exit the market when DDR3 supplants DDR2, Wang said.
In the meantime, DDR2 pricing is poised to fall once again. However, Wang warned that chip suppliers shouldn't take this as a sign that DDR2 is here to stay and they need to be aware of DDR3's impending march into the mainstream.
Once upon a time, I dismissed the iPhone as a wannabe smartphone, lacking the key features that truly warranted that label. Since I wrote that column about two years ago, Apple has gone on a feature-adding rampage—adding push email, support for Exchange servers, third-party applications, and a veritable alphabet soup of new acronyms (GPS, MMS, and 3G, for starters). Two years into the iPhone era, the device is so much more than a phone with an iPod attached— it’s an instant-on, always-connected, pocket-sized computer.
On paper, the 3GS doesn’t seem like a major upgrade from the previous-generation iPhone, especially when you consider that many of the bullet points on the 3GS’s feature list came to older iPhones in the form of the 3.0 firmware release. And at first glance, even the new 3GS-exclusive features—a faster CPU, more memory, a more capable GPU, faster network connectivity, a higher-resolution camera that can finally shoot video, voice control for key features, and a compass—seem like a mixture of unsexy, incremental, shoulda-been-there-already features, and just plain meh. Worse, some of the features require carrier support, so things like MMS messages, higher-speed HSPDA support, and tethering won’t be available in the United States until AT&T deigns to support them.
MSI’s latest venture into the netbook market offers slightly faster performance than the rest of the netbooks we’ve tested with much longer battery life to boot, but the nine-cell battery that makes that possible sends the MSI Wind U123 into the heavyweight range. It makes us wonder: How heavy can a netbook become before it stops really being a netbook? Do we buy them for their formfactor or their performance? Or is it just the price?
The battery is the first thing we noticed about our Wind review unit. The dang thing juts from the back of the netbook, raising the back end more than an inch from horizontal and adding more than a pound to the total weight—making the lap weight three pounds, four ounces. But it’s worth it if battery performance is king. In our full-screen DVD-video battery rundown test, the U123 far outlasted the competition, achieving just over seven hours of playback. The previous netbook record was shared by two Eee PCs, the 901 and 1000HE, both of which clocked in at five and a half hours. This means a nine-cell-powered Wind U123 will likely get eight to nine hours of light usage on a single charge.
Remember Chumby, the squishy Internet appliance with a 3.5-inch touchscreen display and WiFi connectivity? Basically a glorified alarm clock, Chumby could also stream news feeds. stock quotes, photos, weather info, and whatever else could be imagined through widgets.
Well, Chumby's back, this time without the squishy exterior and renamed the 'One.' The new model puts a bigger focus on radio features with Pandora support and the ability to access other internet radio stations. And like the original, you can install widgets, of which there are about 1,500 to choose from. The One touts a faster processor, bumping up from 350MHz to 454MHz, but otherwise the specs look to be the same.
Look for the One to retail for about $100 in a month or so.
Sources at graphics card makers expect AMD to unveil the ATI Radeon HD 5770 and 5750 in October, and Radeon HD 5870 X2 and Radeon HD 5850 X2 a month later. The report adds that AMD will launch the single-GPU Radeon HD 5890 when the market seems to plead for it. That apparently is Digitimes’ way of saying that its sources have no idea when the Radeon HD 5890 will be released.
With 802.11n Draft 2.0 routers becoming as common as Storm Troopers at Comic-Con, manufacturers need a feature that sets their product apart from the crowd. Like many of its competitors, Belkin added a second radio to its N+ Wireless Router—but this one is used for a very different purpose.
Rather than operating on a separate frequency (to separate audio and video streams from more mundane data), the second 2.4GHz radio on Belkin’s router establishes a guest network that limits clients to Internet access. Belkin’s web interface provides extremely limited access to this second radio’s settings: You can turn this radio on or off, change its SSID and passphrase, and choose between WPA/WPA2 pre-shared key or “Hotel Style” security.
E-book readers are poised to become as popular as netbooks, and it's Amazon who stands to benefit the most, whose Kindle readers lead the charge. But the handheld digital readers are best served for personal use and not in an academic setting, suggests Princeton University.
As part of a pilot program, 50 Princeton students received a Kindle DX e-book reader at no cost, but according school newspaper The Daily Princetonian, "many of them said they were dissatisfied and uncomfortable with the devices."
The Kindles were given to students and faculty in three courses -- WWS 325: Civil Society and Public Policy, WWS 555A: U.S. Policy and Diplomacy in the Middle East, and CLA 546: Religion and Magic in Ancient Rome. In all three classes, the general consensus was that the devices were too difficult to use.
"I hate to sound like a Luddite, but this technology is a poor excuse of an academic tool," said Aaron Horvath, a student in Civil Society and Public Policy. "It's clunky, slow, and a real pain to operate."
Horvath went on to explain that by trading in textbooks for the Kindle, students lose the ability for physical interaction, including highlights, page-tearing, sticky notes, margin notes, and so forth.
