Sounds like Notbooks are making a dent: AMD says it's shipped five million Fusion processors since the architecture's debut, according to a report at  CNET . In January, the company said the hybrid CPU / GPU chips had momentum, and as of last month it was quoting 3.9 million APUs out in the wild, but this week AMD says that demand has overtaken supply and it's completely sold out of the Atom alternative. Sounds like Intel's more than justified in seeking out hybrid solutions of its own, no matter where it might have to look to get a leg up in the integrated graphics market. Here's hoping AMD's other Fusionchips show just as much pep per penny (and milliampere-hour) as the original processor. CNET

It seems like the ongoing rivalry between Facebook and Google has taken a turn for the subversive. Last night, a spokesman for the social network confirmed to the  Daily Beast  that Facebook paid a top PR firm to spread anti-Google stories across the media and to encourage various outlets to examine allegations that the Mountain View company was violating user privacy. The PR firm, Burson-Marsteller, even offered to help blogger Chris Soghoian write a critical op-ed piece about Social Circle -- a service that allows Gmail users to access information on so-called "secondary connections," or friends of their friends. Social Circle, in fact, seems to have been at the epicenter of Facebook's smear campaign. In a pitch to journalists, Burson described the tool in borderline apocalyptic terms: "The American people must be made aware of the now immediate intrusions into their deeply personal lives Google is cataloging and broadcasting every minute of every day-wi...

Looks like 3D isn't just a fad, folks, so long as we're talking about silicon -- Intel just announced that it has invented a 3D "Tri-Gate" transistor that will allow the company to keep shrinking chips, Moore's Law naysayers be darned. Intel says the transistors will use 50 percent less power, conduct more current and provide 37 percent more speed than their 2D counterparts thanks to vertical fins of silicon substrate that stick up through the other layers, and that those fancy fins could make for cheaper chips too -- currently, though, the tri-gate tech adds an estimated 2 to 3 percent cost to existing silicon wafers. Intel says we'll see the new technology first in its 22nm Ivy Bridge CPUs, going into mass production in the second half of the year, and it's planning 14nm chips in 2013 and 10nm chips in 2015. Also, 3D transistors won't be limited to the cutting edge -- Intel reps told journalists that they "will extend across the entire range of...
