The Inquirer learned ATI's upcoming R600 will have a power consumption of 250W!
The currently fastest ATI, R580+ or Radeon X1950 XTX consumes up to 125W i a worst case scenario and heavy 3D while you can suck up 145W out with the dual chip X7950 GX2 card.
This means that the R600 will consume twice as much power, and probably will end up close to twice as warm but we also hear it will get much faster then the current cards with sixty four pipelines. It could easily end up twice as fast than the current ATI offerings.
The ATI R600 GPU is expected to arrive in January or February.
