6970/6950 performance

Anyone done any performance testing on these?

nbody? FFT? etc

I'm just after a general sense of where things have improved and by how much.

How indicative is the Stream KernelAnalyzer of relative performance between these and the 58xx series.

6970/6950 performance

The 5870 performed just over 544 Gflops/s in double precision (what anyone actually cares about) while the 6970 does 675.75. That means the 6970 is theoretically 1.24x faster doing nothing but MADs. The 6970 also has more memory bandwidth. With these two factors alone, I'd expect to see a 1.1-1.5x speedup in compute bound applications.
