New gen vs current gen: graphic card power consumption comparison
Thanks to the 65nm & 55nm processing, the new-gen graphic cards have a impressive power concumption, no matter G92 or RV670. Because of the PowerPlay technology in RV670, HD 3800 series have obvious lower power consumption in idle mode. Because PowerPlay is only enable in idle, so when cards running in load mode the gap between G92 and RV670 are more smaller than idle.
When using ATI Tool’s 3D view, Geforce 8800GT and Radeon HD 3870 is very close, 8800GT even 2 watt lower than HD 3870. And comparing the load mode of the new G92-8800GTS with old G80-8800GTS also have 2 watt’s diference; but in idle mode, there is a 20 watt’s gap between them. I guess using the new 65nm processing to shrink GPU core only affect their idle power consumption.
Just for your information, G92-8800GTS engineering Sample’s power consumption is a bit higher than G92-8800GTS retail version about 2watt in idle and 5watt in full load. In the chart up there the G92-8800GTS is an retail version.
The release date is closing, and we getting more and more informations about G92-8800GTS. What’s more, we heard that Gigabyte already begin selling G92-8800GTS in Singapore at about $370. Hope guys there can get one and give another full review.
