Not sure why that matters? It's the first "next gen" in a while that used less power than the "last gen".
the 7900s are actually using
more power under load than their respective 6900s...
What I want to know is
1) Why was 7950 allowed to have non ref designs from the get go and not 7970?
2) Why aren't they releasing a 1.5gb version now
3) Seems backwards to make non ref 7950 but only ref 7970s arghh (guess i'm going water)
Seems like a good card, still cheaper than gtx 580. but I bet a 399$ 1.5gb version would sell like hotcakes, I wonder why AMD didn't release that version?
obviously AMD wants to increase the gap between low and high end by making it easier for AIB partners to favor the 7970 and relatively neglect the 7950 (AT's generally negative review of the XFX BEDD 7950 reflects that thus far), as well as make sure that anyone going water will likely go with a reference 7970 instead, which is more money for both AMD and the partners.
Basically I think AMD has learned their lesson, the 5850 and
especially the 6950 were simply
too good for the consumer, and while they certainly helped boost AMD's reputation amongst enthusiasts, AMD would rather we be making more money, not only on a much more expensive 7950 (relative to 5850/6950), but to be encourage consumers to spend even more money on their highest end part as its only $100 more.
We're a far cry from the days of the $260 5850
smashing the GTX285. The 7950 is certainly more than a fair deal, but for $450 and losing in some situations to the 580, its simply not the same. And its probably all for the better as it means we're finally seeing some excellent competition the likes of which we really haven't seen since the days when ATI first started to truly make some noise with the 9700 Pro.
Granted, on the other side of the coin they are leaving quite a bit of room for the 7800s, which could very well end up being even better parts for their generation than the 6800s were.
