Intel expands 3rd-generation CPU range, announces new 3GHz Core i7 Extreme Edition mobile processor
Intel's quad-core Ivy Bridge processors have been doing the rounds since April, but the chipmaker continues to expand its selection, now adding a new high-end Core i7 mobile processor. Clocked at 3.0 GHz and priced at $1,096, the Core i7-3940XM is a quad-core 22 nm chip, packing Intel's HD 4000 series GPU and 8MB of L3 cache. According to the recently revealed pricing list, it'll be joined by two more Core i7 models, the 2.8GHz i7-3840QM and the 2.7 GHz i7-3740QM.

Multi-gigabit wireless broadband within our grasp, capped data plans laugh in our face
Bring it on, LTE-Advanced. In case you've been looking for ways to eat up your capped data plan any faster, a researcher from Samsung proclaims that speeds up to 5.5gbps (yes, with a g) might be reachable within the next five years -- as long as all the stars align, that is. Jerry Pi demonstrated the idea, which involves the use of millimeter wave spectrum that lies between 3GHz and 300GHz. If -- and that's a big if -- the spectrum can be secured, the next hurdle will be the engineering challenge of deploying a wireless broadband network at such high frequencies; even tiny oxygen molecules, let alone walls and trees, would easily break up a signal at that range. Pi mentions that he and his fellow researchers are working on a few ideas to get around these obstacles, and outlines everything in significant detail in his 100+ slide presentation, which can be accessed below. Don't get us wrong: the idea of broadband data speeds hitting 5.5gbps makes us salivate, but it would definitely need to come with an unlimited plan. Just sayin'.
