At IDC 2011, successor of Intel’s Sandy Bridge, the Ivy Bridge was announced and has been officially scheduled for 2013 which will be built with Haswell micro-architecture. Intel will be using its Tri-gate technology for the manufacturing of Ivy Bridge which will take down the 32nm technology used in Sandy Bridges to 22nm for Haswell. Ivy Bridge is now seen as a shrunken Sandy Bridge with the new 22nm architecture which will be using Intel’s tick-tock model.

Otellini, CEO & president of Intel, announced during his keynote that Haswell was not only designed for power saving but also for a system level power management framework, that would reduce the power consumption by more than 20% over the current Sandy Bridge. This would enable an all day usage for notebooks and 10 days of standby along with increasing the processor speed with the new technology.
The production is expected to begin in the fourth quarter of 2011 along with the first look at CES 2012 to be held in January. To utilise the best out of the Haswell’s “20X” feature, Intel has instituted $300m for the development of Ultrabook slim notebooks which would make the best use of the Haswell technology to consume less power.
With the new fast Ivy Bridge processors on Haswell technology and Windows 8 launching mid-next year, the Ultrabooks are definitely going to be something to look out for in 2012.
