Intel today officially debuted its long-awaited X7900 CPU. The Core 2 Duo Extreme dual-core processor was unveiled at the 2007 Games Convention in Germany and is Intel's highest performing notebook CPU to date.

The X7900 is clocked at 2.8GHz, contains 4MB of L2 cache and runs on an 800MHz FSB. Intel said the CPU also features mobile-specific power-saving features, that will help computer manufacturers to deliver more energy-efficient and higher-performing designs.

It also claimed the X7900 will be exploited for high-end gaming and demanding applications, both at home and when out and about. It’s expected to appear within systems from the likes of Asus, Dell and Medion within the next four weeks.

Earlier this year Japanese-language site PCWatch published a roadmap for several Intel chips, in which it predicted that the 2.6GHz X7800 would debut in Q3 and the X7900 would debut in Q4.

Intel also gave drooling journalists a taste of its X38 Express desktop chipset. Falling under the company’s Intel 3 Series, the X38 allows two graphics cards to be run in the same system and is compatible with DDR3-1333 memory. While all existing Core 2 Extreme, Core 2 Quad and Core 2 Duo processors are supported.
