An anonymous reader writes “Several fake NVIDIA cards — probably GeForce GT 440 — have had their BIOS reflashed to report themselves as GeForce GTX 660. They were sold under the brand “GTX660 4096MB Nvidia Bulk” but only deliver 1/4 of the speed of a real GTX 660. Investigations are ongoing into who did the reflashing, but several hundred of them have already been sold and are now being recalled.” Read more of this story at Slashdot.
An anonymous reader writes Facebook today revealed details about Autoscale, a system for power-efficient load balancing that has been rolled out to production clusters in its data centers. The company says it has “demonstrated significant energy savings.” or those who don’t know, load balancing refers to distributing workloads across multiple computing resources, in this case servers. The goal is to optimize resource use, which can mean different things depending on the task at hand. Read more of this story at Slashdot.

You eventually tune it out, but the constant whir of a desktop computer’s cooling fans can take a toll on your psyche. It’s like a buzzing mosquito that never strikes, and never stops. So the folks at a German company called Silent Power have created a compact desktop PC that trades noisy fans for a block of exposed copper foam that dissipates heat so effectively no fans are required.

Chromebooks are great if you want a super cheap computer, but they’re not without their limitations; you (basically) have to run everything in a browser. And Microsoft is aiming to give them some competition with full Windows 8 machines around those same, dumb low price points . Read more…

redletterdave (2493036) notes that Taiwan Semiconductor Manufacturing Co. (TSMC) has shipped its first batch of microprocessors to Apple as the iPhone maker looks to diversify its overseas suppliers. Apple will continue to rely on Samsung for its microprocessors, but as the rivalry between Apple and Samsung heats up in the mobile and soon wearable arenas, the deal with TSMC allows Apple to be less reliant on Samsung and therefore have more leverage with respect to price negotiations for future chips, as TSMC has supplanted Samsung Electronics as Apple’s chief chipmaker for iPhones and iPads. Since 2011, Apple has been striking deals with other display and chip makers around Asia to reduce its dependence on Samsung. As a result of this slowdown in sales, Samsung on Monday announced operating income for its fiscal second quarter had sunk to a two-year low, blaming ‘weak’ sales of low- and medium-end smartphones, strong competition and subpar demand. It may not be a household name like Intel or AMD, but TSMC is the world’s biggest chip maker by revenue. Read more of this story at Slashdot.

An anonymous reader writes “This article provides a technical look at the challenges in scaling chip production ever downward in the semiconductor industry. Chips based on a 22nm process are running in consumer devices around the world, and 14nm development is well underway. But as we approach 10nm, 7nm, and 5nm, the low-hanging fruit disappears, and several fundamental components need huge technological advancement to be built. Quoting: “In the near term, the leading-edge chip roadmap looks clear. Chips based on today’s finFETs and planar FDSOI technologies will scale to 10nm. Then, the gate starts losing control over the channel at 7nm, prompting the need for a new transistor architecture. … The industry faces some manufacturing challenges beyond 10nm. The biggest hurdle is lithography. To reduce patterning costs, Imec’s CMOS partners hope to insert extreme ultraviolet (EUV) lithography by 7nm. But EUV has missed several market windows and remains delayed, due to issues with the power source. … By 7nm, the industry may require both EUV and multiple patterning. ‘At 7nm, we need layers down to a pitch of about 21nm, ‘ said Adam Brand, senior director of the Transistor Technology Group at Applied Materials. ‘That’s already below the pitch of EUV by itself. To do a layer like the fin at 21nm, it’s going to take EUV plus double patterning to round out of the gate. So clearly, the future of the industry is a combination of these technologies.'” Read more of this story at Slashdot.

angry tapir writes: Unisys is phasing out its decades-old mainframe processor. The chip is used in some of Unisys’ ClearPath flagship mainframes, but the company is moving to Intel’s x86 chips in Libra and Dorado servers in the ClearPath line. The aging CMOS chip will be “sunsetted” in Libra servers by the end of August and in the Dorado line by the end of 2015. Dorado 880E and 890E mainframes will use the CMOS chip until the servers are phased out, which is set to happen by the end of 2015. Read more of this story at Slashdot.

An anonymous reader writes 4K monitor prices have fallen into the range where mainstream consumers are starting to consider them for work and for play. There are enough models that we can compare and contrast, and figure out which are the best of the ones available. But this report at The Wirecutter makes the case that absent a pressing need for 8.29 million pixels, you should just wait before buying one. They say, “The current version of the HDMI specification (1.4a) can only output a 4096×2160 resolution at a refresh rate of 24 Hz or 3840×2160 at 30 Hz—the latter, half that of what we’re used to on TVs and monitors. Connect up a 4K monitor at 30 Hz via HDMI and you’ll see choppier animations and transitions in your OS. You might also encounter some visible motion stuttering during normal use, and you’ll be locked to a maximum of 30 frames per second for your games—it’s playable, but not that smooth. … Most people don’t own a system that’s good enough for gaming on a 4K display—at least, not at highest-quality settings. You’ll be better off if you just plan to surf the Web in 4K: Nvidia cards starting in the 600 series and AMD Radeon HD 6000 and 7000-series GPUs can handle 4K, as can systems built with integrated Intel HD 4000 graphics or AMD Trinity APUs. … There’s a light on the horizon. OS support will strengthen, connection types will be able to handle 4K displays sans digital tricks, and prices will drop as more 4K displays hit the market. By then, there will even be more digital content to play on a 4K display (if gaming or multitasking isn’t your thing), and 4K monitors will even start to pull in fancier display technology like Nvidia’s G-Sync for even smoother digital shootouts.” Read more of this story at Slashdot.
