Expreview, has got hold of information which details NVIDIA's new 9600GT Green Edition GPU. It appears to be nothing more than a BIOS tweak, but as such has resulted in a 37W (39%) drop in power consumption, allowing the card to function without the need of an external power connector. This has resulted in a new board revision number P562. The memory clocks remain the same at 900 MHz, but the core drops to 600 MHz, with 1500 MHz on the shaders. By doing this, NVIDIA have been able to drop the core voltage from 1.1V to 1.0V, most likely providing the biggest saving in power.
