AMD's New Radeons Revisit Old Silicon, Enable Dormant Features 75

crookedvulture writes "The first reviews of AMD's Radeon R7 and R9 graphics cards have hit the web, revealing cards based on the same GPU technology used in the existing HD 7000 series. The R9 280X is basically a tweaked variant of the Radeon HD 7970 GHz priced at $300 instead of $400, while the R9 270X is a revised version of the Radeon HD 7870 for $200. Thanks largely to lower prices, the R9 models compare favorably to rival GeForce offerings, even if there's nothing exciting going on at the chip level. There's more intrigue with the Radeon R7 260X, which shares the same GPU silicon as the HD 7790 for only $140. Turns out that graphics chip has some secret functionality that's been exposed by the R7 260X, including advanced shaders, simplified multimonitor support, and a TrueAudio DSP block dedicated to audio processing. AMD's current drivers support the shaders and multimonitor mojo in the 7790 right now, and a future update promises to unlock the DSP. The R7 260X isn't nearly as appealing as the R9 cards, though. It's slower overall than not only GeForce 650 Ti Boost cards from Nvidia, but also AMD's own Radeon HD 7850 1GB. We're still waiting on the Radeon R9 290X, which will be the first graphics card based on AMD's next-gen Hawaii GPU." More reviews available from AnandTech, Hexus, Hot Hardware, and PC Perspective.

Video Tour Houston's Texas-Sized Hackerspace (Video 2 of 2) 45

A few weeks ago, on his way to LinuxCon, Timothy stopped by the biggest hackerspace he'd ever seen. Houston's TX/RX Labs is not just big — it's busy, and booked. Unlike some spaces we've highlighted here before (like Seattle's Metrix:CreateSpace and Brooklyn's GenSpace, TX/RX Labs has room and year-round sunshine enough to contemplate putting a multi-kilowatt solar array in the backyard. Besides an array of CNC machines, 3-D printers, and wood- and metal-working equipment, TX/RX has workbenches available for members to rent. (These are serious workspaces, made in-house of poured concrete and welded steel tubing.) There's also a classroom full of donated workstations, lounge space, a small collection of old (but working) military trucks, and a kitchen big enough for their Pancake Science Sunday breakfasts. Labs member Steve Cameron showed me around. You saw Part One of his tour last week. Today's video is Part Two.

Digital Revolution Will Kill Jobs, Inflame Social Unrest, Says Gartner 754

dcblogs writes "Gartner says new technologies are decreasing jobs. In the industrial revolution — and revolutions since — there was an invigoration of jobs. For instance, assembly lines for cars led to a vast infrastructure that could support mass production giving rise to everything from car dealers to road building and utility expansion into new suburban areas. But the "digital industrial revolution" is not following the same path. "What we're seeing is a decline in the overall number of people required to do a job," said Daryl Plummer, a Gartner analyst at the research firm's Symposium ITxpo. Plummer points to a company like Kodak, which once employed 130,000, versus Instagram's 13. The analyst believes social unrest movements, similar to Occupy Wall Street, will emerge again by 2014 as the job creation problem deepens." Isn't "decline in the overall number of people required to do a job" precisely what assembly lines effect, even if some job categories as a result require fewer humans? We recently posted a contrary analysis arguing that the Luddites are wrong.

NSA's New Utah Data Center Suffering Meltdowns 241

linuxwrangler writes "NSA's new Utah data-center has been suffering numerous power-surges that have caused as much as $100,000 damage per event. The root cause is 'not yet sufficiently understood' but is suspected to relate to the site's 'inability to simultaneously run computers and keep them cool.' Frustrating the analysis and repair are 'incomplete information about the design of the electrical system' and the fact that "regular quality controls in design and construction were bypassed in an effort to fast track the Utah project."" Ars Technica has a short article, too, as does ITworld.

AMD Intentionally Added Artificial Limitations To Their HDMI Adapters 256

An anonymous reader writes "NVIDIA was caught removing features from their Linux driver and days later Linux developers have caught and confirmed AMD imposing artificial limitations on their graphics cards in the DVI-to-HDMI adapters that their driver will support. Over years AMD has quietly been adding an extra EEPROM chip to their DVI-to-HDMI adapters that are bundled with Radeon HD graphics cards. Only when these identified adapters are detected via checks in their Windows and Linux Catalyst driver is HDMI audio enabled. If using a third-party DVI-to-HDMI adapter, HDMI audio support is disabled by the Catalyst driver. Open-source Linux developers have found this to be a self-imposed limitation and that the open-source AMD Linux driver will work fine with any DVI-to-HDMI adapter."
