Lion is soon out and folks will be able to benchmark GTX 5xx series.
The following is taken from my Windows 7 box running a pair of GTX 560's. They came factory OC'd at 900/1800/2004 (4008) 1.012 volts. However, I under-clocked/under-volted them down to 855/1710/2100 (4200) 0.987 volts.
Single-Precision: ./nbody -n=61440 -benchmark
-- One GPU: 548.804 single-precision GFLOP/s
-- Two GPUs via -numdevices=2: 1068.541 single-precision GFLOP/s
Double-Precision: ./nbody -fp64 -n=30720 -benchmark
-- One GPU: 89.702 double-precision GFLOP/s
-- Two GPUs via -numdevices=2: 166.125 double-precision GFLOP/s
I wish that NVIDIA will one day make a single-PCB card containing 2 GTX 560's to have a good balance for compute-power and electric power utilization.
