Hasta La Gadget!

Just as you’ve cozied up with “Tahiti” and “Cape Verde,” AMD has returned to grow its “Southern Islands” family of graphics cards with four fresh FirePros, offering up to four teraflops of graphics computing power. That spec can be found in the company’s new W9000, which is capable of four TFLOPs single precision and one TFLOP double precision with a price tag just shy of $4,000. That behemoth of a card offers 6GB of GDDR5 RAM and requires 274 watts of power. More humble members of the fam include the W8000, which has the same form-factor as the higher-end W9000, but eases back on the specs, consuming 189 watts of power and carrying a $1,599 price tag.

We had a chance to take a closer look at both cards at SIGGRAPH, and while they packed a significant amount of heft, you’ll likely never take a second look once they’re buried away in your tower rig. Fans of smaller housings (and price tags) may take notice of the W7000 and W5000, which are both considerably more compact and require less power to boot, with pricing set at $899 and $599, respectively. Those cards were also on hand for our demo, and can be seen along with the top two configs in our gallery below. You can also sneak a closer peek in the hands-on video after the break, and glance at the full specs over at our news post from earlier today.

Think those are some pretty slick graphics in your Galaxy S III? Samsung’s latest smartphone packs some mighty graphics prowess of its own, thanks to the Mali-400 MP GPU, but once you spend a few minutes with the Mali-T604, the company’s next-generation chipset, the improvements become quite clear. After seeing the Mali-T604 in action, as we did at SIGGRAPH today, the capabilities leave us hopeful for the future, and perhaps feeling a bit self-conscious about the silicon currently in our pockets. The reference device on hand was operating in sync with a variety of unnamed hardware, protected from view in a relatively large sealed box. We weren’t able to squeeze many details out of ARM reps, who remained mum about the demo components, including clock speed, manufacturer and even fabrication size. What we do know is that we were looking at a quad-core Mali-T604 and dual-core ARM Cortex-A15 processor, with a fabrication size in the range of “28 to 40 nanometers” (confirming the exact size would reveal the manufacturer). Clock speed is also TBD, and the early silicon on demo at the show wasn’t operating anywhere close to its top end.

In order to experience the T604, we took a look at three demos, including Timbuktu 2, which demonstrates elements like self shadowing and depth of field with OpenGL ES 3.0, Hauntheim, which gives us an early look at physics simulation and HDR lighting with OpenCL, and Enlighten, which rendered silky smooth real-time illumination. You can see all of the demos in action after the break, and you can expect T604-equipped devices to make their debut beginning later this year — ARM says its working with eight manufacturers to get the licensed tech to market as early as Q3.

If you told us on Monday that we’d be capping our week off by checking out an innovative cranial drill, we likely would have just stared at you funny. But here were are and here it is, a device referred to, quite straightforwardly, as the Cranial Drilling Device with Retracting Drill Bit After Skull Penetration. The drill was designed by a team of researchers at Harvard in order to address a major shortcoming with manual drills. Such devices require neurosurgical training in order to know precisely when to stop so as to not damage underlying brain tissue. In certain instances, such as emergency rooms and the backs of ambulances, medical practitioners may require a cranial drill in order to perform procedures such as the insertion of pressure monitors, with nary a neurosurgeon to be found. The Harvard team has concocted a drill that automatically retracts back into its protective casing, as soon as it’s finished drilling through the skull, using a bi-stable mechanism that is active as the drill spins.

After the break, team member Conor Walsh explains the technology is a manner that, thankfully, is not quite brain surgery.

Should you ever find yourself needing to discuss the state of the robotic hand in the early 21st century, Harvard professor Robert Howe seems about as good a place to start as any. The professor founded the school’s BioRobotics Laboratory in 1990 and has devoted a good deal of his time to the quest for perfect robot extremities. The last few years have seen a number of breakthroughs for Howe and his team including, notably, the SDM (Shape Deposit Manufacturing) hand, an adaptable and rugged robot gripper that utilizes a single motor to manipulate its eight joints. Such machines have, in the past, often relied on precise image sensing to determine the exact size and shape of an object, in order to configure their digits perfectly before attempting to pick it up. The SDM hand is a lot more forgiving. The pulley system at play distributes equal tension to the fingers in an adaptive transmission that allows motion to continue in other fingers, should one’s movement be hampered.

The joints themselves are extremely compliant as well, adapting and conforming to the shape of an object, thanks in part to their ability to pivot in three dimensions. The Shape Deposit Manufacturing technology used to create the fingers, meanwhile, adds an important level of durability, letting Howe bang them against a table (a trick he happily performed for us) and expose them to water — both features that are quite often absent in more complex (and far more expensive) models. The SDM technology, developed at Stanford, allows for the creation of fingers that are a single piece, with their parts embedded in plastic. The larger model shown off by Howe serves as great visual when describing the benefits of the single motor system, but the team has also developed a smaller version, with the requisite motors embedded in a far more compact chassis, which we also got a peek at.

The hand will likely be targeted at home and office use, with some key applications for assisting the disabled. Check out a video of Howe describing the technology to us during our visit to the school and a clip of the SDM doing its thing in the labs, which should help feed your desire to watch robot hands get banged by hammers.

Tweetbot‘s been offering a rough-around-the-edges alpha version on its upcoming refresh for a few weeks now, but it’s the latest update that’s caught our attention — again. There’s several substantial changes that could tempt you away from other desktop Twitter clients. These include a new multiple account view, with separate columns that can either be docked to your main feed or left in their own window. You can spin out mentions and search results into their own space, and even adjust each column’s height and width — if you’re looking to squeeze even more Twitter content into a single screen. A new menu bar icon offers access to your multiple accounts, new tweets, direct messages and mentions, while the latest build also improves support for media upload and Mountain Lion‘s notification bar. Tweetbot’s alpha is still free to try for now, but once the kinks are eventually worked out, expect to pay for the finished article.
