TheRegister reports that AMD will indeed release its 'RV670' graphics chip on 19 November. As yet, however, RV670's go-to-market branding remains unknown - some pundits have suggested ATI Radeon HD 2950 Pro - but American Technology Research's Doug Freedman last week told investors that the part will debut on 19 November. The part is a 55nm version of the existing 'R600' GPU core. According to an ExtremeTech report, Freedman confirmed past reports that the two versions of RV670 due to be launched, 'Gladiator' and 'Revival', run at 825MHz and 750MHz, respectively. "The main difference between the two will be Gladiator's adoption of GDDR 4 memory and an improved memory interface - 2.4GHz vs. 1.8GHz," he wrote.

Also, in a post on the company's official Team ATI forums, an administrator who calls himself ATi_Guy has posted a link to a PDF white paper regarding the DirectX 10.1 application programming interface. The white paper appears to originate from AMD itself, and it talks of yet-unreleased Radeon HD 3800 graphics cards, their 55nm transistor design, and their support for DirectX 10.1 and PCI Express 2.0. If you've been following the graphics rumor mill over the past few weeks, you'll know the Radeon HD 3800 series is believed to be the offical brand name for AMD's upcoming RV670 graphics processor, which is expected to roll out on November 15.
