Intel celebrated the one-year anniversary of its successful Atom platform Tuesday night by launching two more, including its first to add dynamic overclocking when needed.

Intel also demonstrated its next-generation "Moorestown" platform, consisting of the "Lincroft" system-on-a-chip, at an event at the Intel Developer Forum in Beijing.

Both the new Z550 and Z515 Atom chips are geared for performance: the Z550 extends the clock speed of the Atom line up to 2 GHz while maintaining an average power of under 22o mW, while the Z515 adds what Intel calls "Burst Performance Technology," an apparent Atom-specific version of the "turbo boost" technology Intel has applied to its desktop processors. The base speed of the chip is 800 MHz, consuming 0.65 watts, according to an Intel spokesman. However, the Z515 will overclock to 1.2-GHz when needed, Intel said; similar Z51x Atom chips are all clocked at 1.1 GHz.

In a keynote address delivered by Anand Chandrasekher, Intel's senior vice president and general manager of the Ultra Mobility Group, Chandrasekher provided what Intel called a sneak peek into Moorestown by showcasing a greater than 10x idle power reduction compared to today's Atom-based platform in a side-by-side demo. Moorestown is due in 2010, Intel has said.

Intel executives also disclosed the inclusion of a "Nehalem-EP" chip for embedded applications, based on Intel's current "Nehalem" architecture found both within the Core i7 and its recently-introduced Xeon 5500 chip.

Pat Gelsinger, Intel senior vice president and general manager of the Digital Enterprise Group, also disclosed that Intel is developing a C++ prototype library for "Larrabee," its graphics technology did in late 2009 or early 2010, and a future parallel programming solution based on "Ct" technology.
