The discrete graphics market has been extremely active lately and the situation is not about to change anytime soon as both Nvidia and AMD are preparing new chips for the 2008 summer-autumn period.
After releasing quite a few G92 cards, the latest being the GeForce 9800 GTX, Nvidia is finally getting ready to move to an evolved architecture with the GT200 GPU(s). Set to power the next high-end offer, the GT200 is apparently taped out some six weeks ago and it is moving towards a Q3/Q4 release with the 'best' estimate seeing it arrive this fall.
The GT200 is a 1 billion transistor chip that is supposed to have over 200 Stream Processors and a 512-bit memory bus.
