This morning we received information on AMD’s ATI Radeon HD 2900 GT – a card that AMD hopes will bridge the gap between the Radeon 2900 XT and the lacklustre “mid-range� Radeon 2600 XT GDDR4.

The HD 2900 GT is based on the R600 graphics processing unit that’s at the heart of the 2900 XT, but the specifications have been cut back in order to fit it into the middle of AMD’s product portfolio. Instead of the 64 five-way superscalar shader processors (320 stream processors), there are just 48 shader processors (or 240 stream processors) in the Radeon HD 2900 GT.

Memory bandwidth has also been cut on the Radeon HD 2900 GT too, as R600’s 512-bit memory interface has been cut quite literally in half to 256-bits.

The GPU clock is set at 600MHz for the time being, while the memory will be 256MB of GDDR3 running at 1600MHz. From what we gather, there will still be 16 pixel output engines in the Radeon HD 2900 GT, meaning that pixel fillrate isn’t too much lower than it is on the flagship HD 2900 XT.
