I seem to recall ATI promising that their next generation cards would idle at ~10W for the high end single chip versions which means the 4850 & 4870. But all the reviews that I’ve seen are showing disappointingly high idle power consumption especially for the 4870.
Is this down to poor BIOS implementations or is a driver upgrade required to add under-clocking in 2D mode?
The HD 3xxx series had a fairly low idle power consumption especially for those board makers that bothered to implement the 2D mode properly in the BIOS. PowerColor and GeCube were two board makers that didn’t implement the down clocking at idle in at least some of their 3 series cards.
