Sse2?

[Demont]

Ok if I am correct here, SSE2 is an instruction set on the cpu that developers can write software for and it gives better performance or something? So why doesn't AMD use this on their chips, seems like they lose 20% of the popular benchmarks just because they don't have this instruction set. Is it really hard to implement or something?

I beleive Opteron with have SSE2. Its Intel's instructions so AMD probably has to liscense it.

oh yes, the hammers will have it but my question is why not now, why not sooner?

Hammer will have the SSE2 Instruction set. So will Barton, I believe.

you're right, sse2 as sse are multimidia instrunction on the chip to improve performance like the mmx in the 200 pentium, but amd's procesors have 3DNow, also is a serie of instructions but to ptimize floating point operations (thats and the bigger l2 cache is why amd is faster in 3d) if I'm not wrong, the XP have sse, 3DNow and 3DNow Pro you probably soon will see programs optimized for both instructions

i think the story on barton was that all they said was that it would have some hammer optimizations, but they didnt say which ones. SSE2 + 512 L2 + dare i say it... approaching 3gig clock rate (serious overclocking of course).... thats some intel skooshing power.
