One of the hottest subjects in the IT industry today is the much-anticipated launch of AMD's next-generation line of Radeon graphics cards, boasting a new architecture and the more energy-efficient 40nm manufacturing process. Reportedly dubbed the Radeon HD 5800 series, the new GPUs have been previously tipped off to launch this month, with a more recent rumor claiming that the cards were supposed to be unveiled late last week. On that note, it looks like the rumor mill just keeps turning and more details about AMD's upcoming cards surface on the Internet.

Following the introduction of its high-end Radeon HD 5800 series of GPUs, the Sunnyvale, California-based chip maker is also expected to debut its new line of mainstream desktop cards, the Radeon HD 5700 series. According to a recent report on Digitimes and its restless industry sources, AMD is planning the launch of its new ATI Radeon HD 5700 series for October, with the debut of the Radeon HD 5770 and 5750 cards.

Unfortunately, there are no specific details on the said cards, as far as the technical specifications and the pricing are concerned, but, according to Digitimes, these will be out between the launch of the high-end Radeon HD 5870 X2, due out in November, and the Radeon HD 5850 and 5870 GPUs, slated for a September 22 release.

In addition to the said mainstream cards, AMD is also looking forward to the launch of its new ATI Mobility Radeon HD 5000 series of GPUs, specifically designed to power an upcoming generation of new portable computer systems. The new, mobile GPUs will be available in the form of the Radeon HD 5800 for the high-end segment, the 5700 for performance, the 5600 for mainstream and the 5400 for the entry-level market. Unfortunately, there are no details on the time frame of the launch of these cards.
