As was the case with Atom Z2460 processor last year, Intel also designed a reference smartphone for Z2420 in order to speed up time to market. The key features of this reference design include a 3.5″ display (480×320), full 1080p30 video encode and decode, XMM6265 HSPA+ modem (Up to 21Mbps), dual SIM card support, FM radio, microSD slot and Wireless Display (WiDi) support. They already have 3 partners (Acer, SafariCom and Lava) who will release a phone in Q1 2013.

Later this year, Clover Trail+ should be available for performance smartphones, and 22nm processors will come soon after for both performance and value smartphones.

In the rest of the mobile part of the keynote, they talked a little bit about Z2760 atom processor currently used in Windows RT tablet, and gave some info about “Bay Trail” a 22nm quad core processor for tablet, that should be available in Tablet for Q4 2013.

The other half of the presentation switched to Core processors, and later this year we should be able to get convertible ultrabooks with low power Core processors (Haswell 7W TDP) providing similar performance to current i3 to i7 processors. They showed some prototypes which can last 13 hours on a charge (Batteries in keyboard and screen), or about 10 hours when the screen is detached. The tablets are just about 1cm thick like ARM based tablets we are accustomed to.
