R600 using 80nm technology, which integrates more than 500 million transistors, as technology advances, Therefore, the core area should not be too large, and this basic picture of the GPU line. According to rumors, AMD said in January 20 after the official R600. The release date is scheduled for the first quarter of 0907, if more time is also released by the end of January.
2GB board will compete against upcoming G80GL and its 0.77/1.5GB of video memory. We do not expect that R600 with 2GB will exist in any other form than in FireGL series, but the final call hasn't been made yet.
RingBus configuration for the R600 as well, but now the number has doubled. The External memory controller is a clear 512-bit variant, while internally you will be treated with a bi-directional bus double the width. The 1024-bit Ringbus is approaching.
80nm chip eating around 300W is far from truth. The thermal budget is around 200-220 Watts and the board should not consume more power than a Geforce 8800GTX. Our own Fudo was right in a detail - the R600 cooler is designed to dissipate 250 Watts. This was necessary to have an cooling headroom of at least 15 per cent. You can expect the R680 to use the same cooler as well and still be able to work at over 1GHz.
its not 500 million transistors, it is more like 720 million. This thing is supposed to be a beast. 512-bit external bus, 1GB GDDR4, theoretical memory bandwidth of 100+MB/s.
