Still lacking a design win in a top tier tablet， Intel is taking another approach—pushing down the power and size of notebook computers. Meet the Ultrabook， a slim， low power laptop Intel will describe this week at theComputex trade show in Taiwan.

The Ultrabook is a work in progress. Early versions will arrive in cases just 20mm thick and price points under $1，000 using versions of Intel 32nm Sandy Bridge processor later this year. AsusTek will be among the companies to ship the systems with its UX21 debuting before the end of the year.

“We are very much aligned with Intel’s vision of the Ultrabook，” Jonney Shih， chairman of Asus will say in scripted comments at an Intel keynote at Computex. ”Transforming the PC into an ultra thin， ultra responsive device will change the way people interact with their PC，“ Shih said.

The Sandy Bridge chips， shipping later this year， will be Intel‘s first to put an x86 and graphics core on the same die， sharing cache memory over a ring bus. Archrival Advanced Micro Devices is sampling similar parts.

Ultrathin， low power laptops running integrated processors have been around for years. Intel aims to push the envelope on the concept with new processors dedicated to such systems.

The move comes at a time when leading tablets such as the Apple iPad， Motorola Xoom， Samsung Galaxy Tab and RIM Playbook all have adopted ARM-based chips. Intel launched a new netbook and tablet division last year， but to date it has only garnered a handful of second tier tablet design wins.

The Ultrabook concept shows both Intel’s frustration at falling behind market trends and gives a gutsy ”bring it on“ call to leading tablet makers. Recently， Intel refocused its road map toward mobile systems for both its Core and Atom chips in an effort to catch up.

The Ultrabook road map

In 2012， Intel will ship versions of its next-generation Ivy Bridge processors for notebooks using its recently announced 22nm process technology with tri-gate transistors. The 3-D transistors will provide significant Mips/Watt gains and sport new chip- or system-level features Intel has promised， but not yet disclosed.

By the end of 2012， as many as 40 percent of shipping consumer portable PCs will be Ultrabooks， Intel predicts.

A third step toward Ultrabooks will come in 2013 when Intel ships Haswell， a second-generation of 22nm chips using a new micro architecture. With Haswell， Intel will shift its notebook design point from the current 30-40W operating target range down to about 10-20W.

Intel announced the road map change at its recent analyst conference， but did not specifically tie it to the Haswell designs. It day say the design shift will be as significant as the first Pentium or the low power Banias design used in its Centrino notebook platform.

Ultrabooks are designed for Microsoft Windows and Apple‘s MacOS. Intel is not actively working on running Google’s Android on the systems. ”We‘ll look at Android if our customers ask for it，“ said Erik Reid， general manager of mobile client platforms at Intel.

”We believe the changes Intel is making to its roadmaps， together with strong industry collaboration， will bring about an exciting change in personal computing over the next few years，“ said Sean Maloney， Intel’s new general manager for China.

Maloney is introducing the Ultrabook concept in a keynote at Computex， his first public address since he suffered a stroke in 2010. He will also make the case that USB 3.0 and Thunderbolt， both emerging in PCs now， are complementary I/O technologies.

Also at Computex， Intel will show smartphone and tablet reference designs for its 32nm Medfield， a single-chip Atom-based SoC. The smartphone will run the Gingerbread version of Android and the tablet will run the Honeycomb version， still being ported to the x86.

So far， Intel has also failed to gain any tier-one design wins for Medfield. It focused most of its attention on Nokia， but the company‘s new chief executive dropped Medfield to embrace Microsoft’s Windows Phone 7.

Intel also will show at Computex as many as ten tablet designs using Oak Trail （Z670）， a two-chip Atom platform using 45nm technology. It will also talk about Cedar Trail， its next Atom-based platform for netbooks， a concept that surged then quickly peaked in the market after the Apple iPad was introduced.
