Sees Heterogeneous System Architecture (HSA) improvements as key to achieving target “25x20”
Advanced Micro Devices earlier this year got slapped with a shareholder class action lawsuit for allegedly overstating the sales prospects of its first generation Llano APUs (Accelerated Processing Units) — chips that house the GPU and CPU on the same die —between October 27, 2011 and October 18, 2012. However, the company, which is confident that it did not commit any violations of Federal Securities Laws in making those statements, does not plan to abandon the practice of making positive statements about the future of its APUs anytime soon. The company is now saying its APUs could end up becoming 25x more power efficient than they currently are by 2020.
Not many of us could convince our bosses that we’re most efficient when working slowly. But then, we aren’t microprocessors. For decades, researchers have known that processors achieve peak energy efficiency when their transistors operate at very low voltages near the threshold between their on and off states.
The technology is called near-threshold voltage (NTV) computing and it could be Intel's trump card in the power saving game.
Back in 2007, the Environmental Protection Agency (EPA) submitted a report (PDF) to Congress noting that energy usage at data centers had doubled between 2000 and 2006, and warned it would double again by 2011, due in part to the growing use of the Internet. The federal government would then be on the hook for $740 million a year just to pay for electricity for these servers and data centers. Well, here we are in the second half of 2011, and it appears the EPA was wrong.
The fine art of browser vendors touting their respective browsers while simultaneously deriding competing ones has been reduced to a very banal affair of late, with most vendors simply concentrating on browsing speeds and HTML5-related enhancements. Does even a single browser vendor not possess the will and imagination necessary to break this trend? Apparently, Microsoft has done just that by comparing IE9’s power consumption habits with that of other major browsers, including Safari 5, Opera 11, Chrome 10, and Firefox 4. Hit the jump for the results.
Asus wants you to feel good about yourself so they went and released the Bravo220 "home entertainment PC card." So what's there to feel good about? For one, the card's 21 percent more power efficient than competing models, so you can look Mother Nature in th eye without that twinge of guilt. And secondly, by investing in the Bravo220 you're making a statement to yourself that you're not going to spend every waking moment playing videogames - that isn't what this card was built for.
As you probably surmised, the Bravo220 is built around Nvidia's GT220 architecture. The GPU comes clocked at 525MHz and there's a 1GB frame buffer chugging along at 400MHz (800MHz effective) on a 128-bit bus. It's HDCP compliant, supports resolutions up to 2560x1600, and has DVI-I, D-Sub, and HDMI ports. So before you ask, no, it's not going to run Crysis, not with the eye candy cranked up anyway, but it will fit right in with your home theater setup.
Towards that end, Asus developed a special Bravo Media Center interface they say is intuitive, and it comes with a remote control to boot. The cooling solution is passive, so there's no fan to distract you from those quiet scenes, and Asus says their Splendid Plus technology will reduce noise and artifacts while improving conversion rates.
What Asus didn't say is when it will ship and for how much.
Concerned about your carbon footprint? Spend more time tweeting and less time Googling. Quirky as it may seem, Raffi Krikorian, a developer for Twitter's Platform Team, has crunched some numbers and found that using Twitter is better for the environment than using Google.
According to Krikorian, each tweet sent consumes about 90 joules, or 0.02 grams of CO2. On a larger scale, there are some 50 million tweets sent on any given day, which works out to about a metric ton of CO2.
A single Google search, on the other hand, consumes about 1 kilojoule and emits 0.2 grams of CO2. So what does it all mean? That "we can do better," apparently.
See all of what Krikorian had to say on the matter in this video (NSFW - language) and skip to the 3m15sec mark.
Most of us view spam as an annoyance with the greatest cost associated with junk email being our time. However an even bigger price is being paid by the environment, a problem underscored by the startling amount of junk email that now flutters across the web. We're talking about 62 trillion spam messages in 2008 alone, according to a report released by McAfee.
In terms of the environment, McAfee researchers say each piece of junk email emits 0.3 grams of carbon dioxide (CO2), or a combined 17 million metric tons of CO2 for all spam-related emissions in 2008.
"The amount released into the atmosphere is significant," said Dave Marcus, director of security research for McAfee. "Spam has a big carbon footprint. It's something people be aware of."
Most of the spam-related greenhouse gas emission -- 80 percent -- comes from the energy used by PC users to view, delete, and sort for legitimate messages, McAfee says. The silver lining here is that by taking steps to reduce spam, you not only reclaim your inbox, but also can have a noticeable impact on the environment.
