The current bulldozer/piledriver chips are on 32nm . We should see GF with 22nm early next year. So they should run quite cool. Remember the old i7 920s were 32nm and when we got sandy bridge on 22nm we got huge power savings while increasing performance. The same thing should happen with AMD when they move down to 22nm .
The ps3 and xbox 360 were close to 200watts when playing a game. I suspect next gen consoles will be around that power envelope . Just like with the last round of consoles they will go through many micron drops and power and heat production will go down.
There are also better cooling options out there. The xbox 360 slim vs the xbox 360 cooling is drasticly improved even while the TDP has gone down. The same with the ps3 .
Remember Piledriver goes from trinity which is a dual core with gpu at 17 watts all the way up to a 4ghz 4 core monster at a 125w TDP .
Jaguar will go from 3-5w to 35w depending on core counts and clock speed with its own gpu. Bobcat cores use roughly 1w. I expect jaguar cores to use the same. So for a quad core your looking at 4w for just the cpu. But performance is really bad
This is the dual core brazos at 1.6ghz. It uses bobcat cores which the jaguar cores will replace

There is a bunch more but looking at the charts its stays pretty close to an Athlon x2 3250e . That's a chip released in 2009 and the Athlon x2s were released in what 2005 . So its quite poor performance. I doubt Sony would use these chips as it will clearly mark the limitations of the system there. If the Durango rumors of a power 7 chip are true there would be no competition.
Ditto, I would say, for an 8 series based chip. Anyway, I would be FAR less concerned with what series the chip is closest to than its performance.
