Radeon HD 5750 and HD 5770 haven't been able to outmuscle older cards that fall into the same price brackets, as shown by our benchmarks, but they're far more power-frugal than most other high-end GPUs.
For example, evaluated as a system, Radeon HD 4870 512MB consumes over 60W more than HD 5770 when under the cosh, and even 46W more when idling.
