On my HD5770 (inflow discharges frequency), I get a Win7 x86_64 ~ 700Gflops,
on Ubuntu 10.04 x86_64 ~ 850Gflops
driver version 10.9 for both OS
What causes such a wide variance in performance?
I used the example of the ATI SDK "MatrixMulImage" with these settings:
MatrixMulImage(const char* name) : SDKSample(name){ seed = 123; input0 = NULL; input1 = NULL; output = NULL; verificationOutput = NULL; n = 3000; m = 3000; k = 3000; blockSize = 8; setupTime = 0; totalKernelTime = 0; iterations = 1; }
