ZDNet reports that Advanced Micro Devices is aiming to release a new generation of desktop and notebook chips on Sept. 22, according to an internal document inadvertently released by the company. AMD's press release schedule, accidentally made public in a mass e-mail on Monday, revealed that date for the unveiling of the Athlon64 for desktops and the Athlon64-M for notebooks. AMD declined to comment on the dates, but acknowledged that the document was an internal file accidentally released to the outside world.
