AMD's ATI Radeon HD 2950 Pro graphics chip will debut on 19 November - a week after Intel's first 45nm processors, also aimed at gamers - it has been claimed.

The DirectX 10.1, Shader Model 4.0 part - codenamed 'RV670' - is believed to support PCI Express 2.0 and HDMI with HDCP.

According to Taiwanese moles cited by DigiTimes, the GPU will be offered in two forms. The first is clocked at 750MHz with the 256MB and 512MB of GDDR 3 it connects to running at 1.8GHz.

A second version sports an 825MHz GPU and is intended to ship on cards with 512MB of GDDR 4 on board. The memory is clocked to 2.4GHz.

At this stage, it's unknown whether these two products - allegedly dubbed 'Revival' and 'Gladiator', respectively - refer to retail and OEM versions of the 2950 Pro, or whether Gladiator is in fact a higher specced part to ship as, say, the 2950 XT.

AMD is expected to have DirectX 10.1-compatible updates to its Radeon HD 2400 and 2600 lines pipelined for an early 2008 release. The chip maker rolled out the Radeon HD 2900 Pro last week.
