Intel's Ivy Bridge chips launch using '3D transistors'

Intel is launching its Ivy Bridge family of processors - the first to feature what it describes as a "3D transistor".

The American firm says the innovation allows it to offer more computational power while using less energy.

The initial release includes 13 quad-core processors, most of which will be targeted at desktop computers.

Further dual core processors, suitable for ultrabooks - thin laptops - will be announced "later this spring".

Intel and PC manufacturers expect the release to drive a wave of new sales.

"The momentum around the system design is pretty astonishing," Intel's PC business chief, Kirk Skaugen, who is spearheading the launch, told the BBC.         More Read
