As many of you have probably seen, there have been a lot of reviews of VIA’s new Nano processor vs. Intel’s Atom processor cropping up in the news lately. With both processors having low power as one of the major selling points, there’s been a lot of interest in both the media and public as to how the two new CPUs would stack up against one another.
If you’ve been following the coverage, you would know that in terms of performance, the VIA Nano came out on top by quite a margin. Here are links to a few of the articles if you’re interested in the finer details:

In terms of straight out power consumption, most sites gave a slight edge to the Atom platform (although the VIA Nano still held a significant performance per watt advantage), but one site in particular, PC Perspective, had a very interesting take on the power draw issue.
PC Perspective decided to use the Watts Up power meter to see how power consumption looked over time when comparing the VIA Nano and Intel Atom processors. In the graph below, the processors were set an MP3 encoding task. The Atom had the edge in power draw, but the Nano was definitely faster to complete the task.
To analyze the results, the reviewer worked out just how much energy each platform took to complete then encoding. the VIA Nano processor used a total of 37,323 watt-seconds (Joules) of energy while the Intel Atom processor used 38,290 watt-seconds (Joules) of energy. Not much of a difference, but at the end of the day the VIA Nano was able to perform tasks faster (by as much as 30% in some cases) while still using less total energy than Intel's Atom.
Certainly a new and interesting way to look at device power consumption. | | Read more... (1 Comments) |

 If you take a look at the left-hand side bar you might notice a few changes. We’ve added two new sections: Green Computing News and Green RSS Feeds.
Green Computing News aggregates all the online green computing news from around the web in an easy-to-view format. It’s updated daily and seeks to include all mention of green computing that crops up in the media.
Green RSS Feeds has a slightly wider focus. This section takes RSS feeds from various sites and displays the title and a brief description of each article those sites post. You can scroll through the article titles and, by clicking on any link that you think might be worth a read, will have that article open in a new window. These feeds cover not just green computing matters, but also wider environmental and technological issues.
These new sections should significantly increase the size of The Green Lounge’s database of green computing information, providing a more valuable resource for readers. | | Read more... (0 Comments) |

Today heralds a new dawn in energy-efficient computing with the announcement of VIA's new Isaiah architecture. This new CPU architecture promises to deliver a massive increase in raw computing power while maintaining a similar power envelope to previous VIA platforms, i.e. significantly more energy-efficient than any other CPU in its class available today.
With Isaiah-based CPUs planed to ship some time in the middle of this year, the VIA Isaiah Architecture has been specifically designed to deliver all the performance and features necessary for running the most demanding computing, entertainment, and connectivity applications, including high-definition video, 3D games, imaging, and virtual worlds.
What impresses me most of course is the implications of this technology. Simply put, it means that power-efficient computing will come of age in 2008. Consumers will soon be able to purchase devices that offer the kind of performance they crave while using significantly less energy than was previously required. This video features Glenn Henry, the President of Centaur Technology Inc, the company that designed tha VIA Isaiah architecture. It's clear from the video that Glen is immensly proud of what his team have achieved, deeming it 'sort of impossible'.

Not quite Everest, but if you check out The Green Lounge gallery you’ll see that there’s been a new section added with photos from the Green California Schools Summit, which I posted about yesterday, and that finishes today. The photos were taken by the team over at Cool Green Gadgets, an excellent new site that keeps track of all that’s happening in the world of eco-friendly consumer products. | | Read more...

Today’s the second of the 3-day Green California Schools Summit at the Pasadena Conference Center in California. California is on the leading edge of the green school movement, creating a state-wide framework and incentives for sustainable schools, and at the summit will focus on strategies, technologies and services that will ensure that new and existing public schools are models of sustainability and provide healthy learning environments for students.
And VIA will be there showcasing power efficient systems that can go a long way towards helping manage a power grid that is becoming increasingly taxed, and has already caused brown and black outs across the state.
