Intel to talk tri-gate, Ultrabooks at IDF

Dylan McGrath

Intel Corp. will raise the curtain Tuesday (Sept. 13) on its annual developer event here, which is expected to feature a more detailed look at its forthcoming 22-nm devices featuring tri-gate 3-D transistor technology and further description of Ultrabooks, Intel's early-stage concept of a category of slim, low power laptops.

The evolution of cloud-based services, the acceleration of the roadmap for Intel's Atom SoC and the detailing by one of Intel's chief technology officer of the latest advances in research around multi-core and many-core technologies are also expected to be highlights of IDF 2011, which runs through Thursday.

In May, Intel initially described its 22-nm process technology, with a surprise twist—the long awaited 3-D transistor design, dubbed tri-gate, that Intel has been developing since at least 2002. This week, Intel is expected to provide more detail about its first 22-nm chips, based on the Ivy Bridge architecture, expected to be in high-volume production by the end of the year.

According to Steven Smith, a vice president and director of netbook and tablet development and enabling at Intel, the firm will provide more technical details on the 22-nm the microarchitecture and process technology, as well as further discussion of the end-consumer benefits of the technology, which promises the potential to reduce power consumption by more than 50 percent compared to Intel's 32-nm processors. Intel will also talk about what it sees as its competitive advantages as an integrated device maker vis-à-vis fabless and fab-lite competitors, Smith said.

On Tuesday, Mark Bohr, an Intel senior Fellow and director of the Technology and Manufacturing Group within Intel, will give a "Technology Insight" presentation on Intel's 22-nm tri-gate transistors, with emphasis on how the technology will provide power-saving advantages for products ranging from high-performance servers to low-power smartphones,

Later Tuesday, Varghese George, Senior Principal Engineer and chief architect of the Ivy Bridge interconnect and integration team, and Thomas Piazza, an Intel senior Fellow and director of graphics architecture for the Intel Architecture Group, will delivera separate presentation on the Ivy Bridge microarchitecture. The presentation will examine some key elements of the Ivy Bridge design and detail how Intel's 22-nm process technology made them possible, according to the IDF agenda.

Atom, Ultrabooks and more

While Intel's 22-nm process technology is initially focused on its mainstream Ivy Bridge processors, it also holds serious promise for Intel's Atom SoCs, according to Smith. Smith said the 22-nm process technology will help Intel extend its advantage in mainstream PC processors and also enable Intel to for the first time field Atom SoCs that are "truly competitive" against ARM-based processors used in smartphones, tablets and embedded systems. Earlier this year, Intel accelerated its Atom roadmap to twice the speed of Moore's Law, Smith noted, with 32-nm Atoms set to roll out next year, followed by 22-nm versions in 2013 and 14-nm versions in 2014.

Smith and Bill Leszinske, general manager of Intel's Atom SoC technology development group, are expected to present further information about the 22-nm tri-gate transistor technology and its low-power capabilities, emphasizing the tight coupling between Intel's design and manufacturing efforts, in a media briefing.

In a keynote presentation Wednesday, Mooly Eden, vice president and general manager of Intel's PC Client Group, will discuss the transformation of the PC from Intel's point of view, focusing on Ultrabooks, the category of slim, low-power laptops that Intel first described at the Computex trade show in Taiwan in May.

Early versions of the Ultrabook based on Intel's 32-nm Sandy Bridge processor are expected to hit the market late this year with price points under $1,000. By the end of 2012, Intel expects that as many as 40 percent of shipping consumer portable PCs will be Ultrabooks.

According to Intel, in his Wednesday keynote, Eden will provide new details on the Ultrabook three-phase roll-out, describe industry momentum behind the new category and highlight related future technologies.

On Thursday, Intel CTO Justin Rattner is expected to reveal the latest advances in research around multi-core and many-core technologies. Rattner will discuss programming techniques that enable developers to harness the power of parallel computing and will also unveil the latest advances in such areas as extreme-scale computing, contextual awareness and near-threshold circuit topologies that dramatically reduce energy consumption, according to Intel.

Other expected highlights

Other highlights of IDF 2011 are expected to be:

Otellini's keynote. As usual, Intel president and CEO Paul Otellini will kick off IDF San Francisco with a keynote speech summarizing his vision for the company. According to Intel, Otellini will focus heavily on the company's ability to deliver seamless, connected and secure computing experiences across a broad range of low-power devices. Look for Otellini to also trumpet the Atom roadmap acceleration and its implications for head-to-head competition against ARM-based processors in smartphones and media tablets. He'll likely also look to sow seeds of doubt about the potential for ARM-based processors to take market share from Intel its core PC processor space following Microsoft's rollout of Windows 8, which will for the first time support ARM-based chips.

Cloud computing. A "Technology Insights" presentation by Stephen Pawlowski, an Intel Senior Fellow and general manager of cross-IAG architecture and pathfinding, is slated to focus on the evolution of cloud computing, including the infrastructure challenges associated with an ever-increasing size of the world's population depending on access to the Internet. Pawlowski will focus on these and other challenges facing the industry and lay out some technologies to address them.

CISO panel. Intel Chief Information Officer Diane Bryant will moderate a discussion Thursday on the rapidly changing security landscape. The panel promises a range of discussions about the security impact of emerging technologies, including consumerization and the move to the cloud. It will also address security paradigms and future trends that are becoming more relevant, such as context-aware computing and personal devices being used in enterprise IT, according to the event's agenda. The panel is scheduled to include Malcom Harkins, Intel's chief information security officer; Patrick Heim, senior vice president and chief trust officer at Salesforce.com; Sherry Ryan, chief information security officer at Blue Shield of California; and Michael Wilson, vice president and chief information security officer at McKesson Corp.
