AMD’s Trinity APU can do some remarkable things, but we still don’t know exactly what magic ingredients make its Piledriver cores superior to the tepidly received Bulldozer. Now though, a firm called Cyclos claims it’s supplying ‘resonant clock mesh’ power-saving technology for use in the new module. In speaking to the media, it’s revealed that this will help to enable a “4+ GHz” factory clock speed, which sounds high if it definitely refers to an integrated chip with low-power credentials. As for the resonant clock mesh itself, it’s a bit like KERS for processors: it recycles clock power instead of letting it dissipate and thereby enables higher clock speeds in “next generation SoCs that also require ultra-low power consumption.” We also know that the technology is financially backed by ARM and Siemens and has seen precious little implementation prior to AMD — which is fine, so long as all that resonance doesn’t make our rig hum even louder.

AMD Piledriver cores will clock over 4GHz, employ ‘resonant clock mesh’ originally appeared on Engadget on Wed, 22 Feb 2012 07:59:00 EDT. Please see our terms for use of feeds.

Like this…only on your face.

Wearing glasses that superimpose a layer of information—nearby pizza places, the local bus line, or, if you’re the Terminator, the amount of ammo left in your weapon—over reality is a long-held techie fantasy. Fighter pilots already use such “heads-up” displays to keep track of vital info while keeping their eyes ahead of them, but despite the constant low buzz about such augmented reality glasses for the rest of us, actual products have been few and far between. Now, though, Google employees speaking to the NYT’s Bits blog have confirmed that Google’s experimental lab is indeed building such a device. Due to come out at the end of the year, these “Google Goggles” are said to function basically as a smartphone you can wear on your face.

According the the Bits blog, users will be able to scroll around on the glasses’ tiny screen using small head motions. The glasses will also feature a low-res camera that monitor the world in front of the user and take pictures, but there are obviously privacy issues at stake with such a feature: apparently the team is currently discussing how to make …

Most people are familiar with the concept of a “carbon footprint,” and some even feel dutifully guilty about their own. “Water footprints” get a little less play. Even though we live on a blue planet (oddly named “Earth” by one of its continentally-biased inhabitants), water is still a precious resource that warrants conservation. After all, over 99 percent of that water is either in salty oceans or frozen glaciers.

A paper published last week in the Proceedings of the National Academy of Sciences delves into an analysis of humanity’s water footprint and the various components that contribute to it. This isn’t the first stab at a global assessment, but it’s a significant improvement on earlier work. And, in one of the more interesting twists, it accounts for the international movement of water use that occurs when a good that requires water is shipped to another country.
