Power consumption of low-end HD7000 series

[tigersty1e]

I'm looking at picking up the HD6450. It has idle of 8 watts and load of 27 watts.

But considering the 7K series will probably include some sort of rebadged HD6450 with 28nm process, how much lower power consumption will I see?

With what looks like nightlight wattage now I wouldn't expect a whole lot more.

Guessing something like 5-6 watt idle and 25 watt loads. ???

40nm > 28nm means the die is smaller by half on a chip with the same architecture ... I'd say a hd7450 would go well below 20w at load.

SA is reporting the low ends are going to be re-branded and stay on 40nm. And only be available for oem at first. That's what we heard about the 6770 rebrand, that it was oem only. Eventually it was released to the market.

The offerings span four families, with model numbers ranging from 7300 to 7600. In short, HD 7350 will be Cedar, HD 7450 will be Caicos, HD 7570 will be Turks Pro and HD 7670 will be Turks XT. All of these GPUs will be made on TSMC 40 nm process, no surprises there. For the sake of brevity and readability, we are not going post the specifications for yet again, as they are literally the same.
