you missed the part where the 5450 uses 10 watts not including board power. the 5450 is 5gflops/W and the 5970 is 15gflops/W. big difference.

but comparing flops to flops as a performance metric is probably about as inaccurate as you can get. we have already seen the 5870 achieve 2.2tflops in sgemm. an ideal case for sandy bridge is 20x slower.
