RV790 gets more efficient Powerplay
Source: ATI-Forum
On the CeBIT 2009 us 6 April was confirmed as release date by the RV790 of several partners. Now us new information was passed on to the current consumption.

So less river is to need after our enterprisenear sources of the RV790 in the Idle mode, than the RV770Pro in the no-load operation and under load reach a level of the RV770XT or are even somewhat under it. This has to do with the fact that one worked at AMD strongly on PowerPlay and also on a new 55nm manufacturing process, which is not to be compared with the manufacturing process of the RV770.

We will see whether these information is confirmed.
