Re: sin(x) performance on x64 and win32

Could somebody test this code with the Intel compiler?

Another contrived example:
 
win32: 281 ms
x64: 390 ms
 
Processor: EM64T Family 15 Model 4 Stepping 8 GenuineIntel ~2793 Mhz
Compiler: VC2005.

#include <tchar.h>
#include <windows.h>
#include <math.h>
#include <stdio.h>
 
 
int main(int argc, _TCHAR* argv[])
{
 double z = 0;
 
 for (int jjj = 0; jjj < 10; jjj++)
 {
   DWORD oldticks = GetTickCount();
 
   double t = 0;
   double dt = 1e-8;
   double a = 2; double b = 3; double c = -5; double d = 20;
 
   for (int i = 0; i < 50000000; i++, t += dt)
   {
     z += ((a * t + b) * t + c) * t + d;
   }
 
   wprintf(L"performance1: %d\n", GetTickCount() - oldticks);
 }
 
 wprintf(L"%g\n", z);
return 0;
}
