We already reported some information about the characteristics of video card NVIDIA GT200, which will appear at the end of the current block .
Today we can describe the quantity of basic functional units in GT200 chip , since precisely these characteristics will determine the advantage value of this new chip over predecessors. The first forecasts speak, that GT200 will be approximately two times faster than G 80.
The quantity of stream processors in GT200 chip will be equal to 240 pieces. For comparison, g92 chip has 128 stream processors . The number of stream processors was almost doubled ( by 193.3 %). G92 chip had 8 clusters on 16 (8 + 8) stream processors each, and GT200 has 10 clusters on 24 (8 + 8 + 8) stream processors each. So the number of stream processors in GT200 chip reaches 24 X 10 = 240 pieces.
Accordingly, certain cheaper products on base of GT200 chip can obtain a lowered number of stream processors, decreased with 24 pieces step . For example, 216, 192, 168 or 144 pieces. The quantity of textural blocks in one cluster GT200 will grew from four to eight, in comparison with G80. GT200 chip in the maximum configuration can possess 8 X 10 = 80 textural blocks.
The quantity of (ROP) blocks will also grew : from 24 pieces in G80, 16 pieces in G92, and 32 pieces in GT200. The memory system bus in GT200 chip will be 512- bit. In this case video card will be equipped with GDDR- 3 memory , which in its best versions operates at 2200 MHz DDR frequency . B
GT200 will also get some architectural innovations. It is assumed that directX 10.1 support will appear .
