Yeah... less clock and disabled units (not all die-size is used) too... a HD 6950 @ 850Mhz could consume close to HD 5870.
The performance/watt advantage was created by VLIW5 ISA vs VLIW4 ISA... VLIW4 have better performance (well at really better efficience that translate in performance).
Big improviments in power consumption just happen when there is a shrink to lower process (eg. 40nm to 28nm).
