----Delivering a multi-core triple threat, AMD announced the addition of AMD Phenom triple-core processors to its desktop roadmap. AMD Phenom triple-core processors, expected to be the world’s first PC processors to integrate three computational cores on a single die of silicon, can help deliver the visual experience, performance and multitasking capabilities of true multi-core technology to a broader audience. Offering state-of-the-art platforms and a next-generation architecture with expected availability in Q1 2008, the industry’s only x-86 triple-core desktop processor shows why AMD’s the smarter choice, with its expanded portfolio for customers to offer platforms with unique multi-core options. AMD Phenom quad-core processors remain on schedule to ship in 2007----
