2.0 GHz memory frequencies? No problem.

Anh beat me to R600 benchmarks by a few mere hours -- when you snooze, you lose at DailyTech. Needless to say, I feel somewhat compelled to add my benchmarks to the mix as well. 

The system I'm using is an Intel Core 2 Extreme QX6800, ASUS P5N32SLI-E with 2x2GB DDR2-800.  My tests this morning used the Catalyst 8.361 RC4 driver.  The card used was a Radeon HD 2900 XT 512MB.

Like Anh, I was able to get pretty close to a 2.0GHz memory clock while still keeping the system stable.  For reference, my GeForce 8800 GTX (core clock at 650 MHz, memory at 2.0 GHz) scores 14128 (1280x1024) and 11867 (1600x1200) on the same system with ForceWare 158.19. 

I'm currently benchmarking the Radeon HD 2900 XTX, though I'll revist the XT if anyone has any particular requests.

Just like sxr7171 said, work is really just how you define it. If you wanted a heater, then a video card is pretty much 100% efficient (discounting generated electromagnetic radiation and whatnot).

In the case of a graphics card, we would consider the ideal amount of power to perform computations and information exchange at the specs of the graphics card, and compare that figure to what it's actually using.
