yes here is how...

look at the sky...if it is blue you have sse2...if it is brown you only have mmx...

Seriously all p4's have sse2...

If i put my k6 in a Ferrari it would be faster than your your pentium 4 or Athlon XP :tongue:

There are times when the sky remotely resembles a shade of brown, so that statement is inaccurate.

<pre>void main()
{
__asm
{
addpd xmm0, xmm0
}
}
</pre><p>Compile and execute that. If it crashed with an illegal instruction exception, you don't have SSE2 support.

Don't you first need to load 2 doubles into xmm0 and xmm1?

cpuid does not actually test if the processor has mmx or sse1 or sse2 support...at least i don't think it does...

codified...what compiler should i use? Is that c?

well if the sky is black it is mmx2...

If it is purple then that is sse5...

If you see a rainbow you have IA64 instruction sets :smile:

cpuid just shows whether your cpu has sse2.
