In a press release issued today, AMD has announced more details surrounding their next mobile platform, dubbed “Puma”. The Puma platform is a redesign, akin to Santa Rosa, intended to improve the overall user experience. It'll be based upon the M690 chipset and utilize dual-core Turion 64 X2 processors, built on 65nm. The new mobile platform centers around the “Griffin” core Turion, which features a number of enhancements intended to prolong battery life and make performance more scalable:

“Through the combination of our recent processor and chipset launches and the Better by Design program, AMD is constantly establishing new heights of competitiveness in serving the needs of our notebook customers,” said Chris Cloran, vice president, AMD Notebook Division. “With the unveiling of the “Puma” mobile platform we’re sending a clear signal to the market that we intend to drive continued innovation in notebook computing in 2008 and beyond.”
