Some Radeon HD 2900 Pro cards are already available in stores for about $249 and by mid-October we can expect the Radeon HD 2900 GT for about $199.
TweakTown reveals the specifications of the Radeon HD 2900 GT. They say the card will have a 600MHz GPU, 256MB 1600MHz GDDR3 memory and a 256-bit memory bus. The GPU is clocked at the same speed as the Radeon HD 2900 Pro, the difference appears to be in the stream processors:
The most interesting part is that the 2900 GT is the first card based on the R600 GPU to have less than 320 stream processors. It doesn’t seem like it’s been too drastically cut back though, as it still has 240 stream processors. Loosing out that many stream processors will reduce the performance by any means and combined with a 256-bit memory interface, this card won’t be able to compete with the 2900 Pro on any given day.
It looks like all remaining features will be the same and from the information we’ve seen, the card will also retain the 6 and 8-pin power connectors and the dual slot cooling, at least on initial cards. Due to the 80nm manufacturing process it’s unlikely that there will be a single slot version of this card, but it could be possible.
The site also claims that with the rumoured launch of a RV670 based Radeon HD 2600 XTX the Radeon HD 2900 GT may have a very short life.
