Sse3 ?

[MaGnatu]

When do u think SSE3 will be ready?
I have a Prescott 3,2 GHz LGA775 WITH SSE3.
Will SSE3 boost the performance?:trash:
Thanks.

It's my understanding that sse3 will not nearly produce the benift we have seen for sse2.

There were comments that sse3 might not be faster at all actually, in any respect I'd say we have to wait a while. Generally new intruction sets are released for P-1 first then prp, and we don't have much if any discussion about sse3 for p-1.

http://www.intel.com/technology/itj/2004/volume08issue01/art01_microarchitecture/p06_sse.htm - look here! i think it's not so hard to upgrade to SSE3 !

The Intel example assumes a complex number is stored in a single SSE2 register. Prime95 instead processes two independent complex multiplies simultaneously by putting two real parts in one SSE2 register and two imaginary parts in another SSE2 register. The advantage is that you get code that is even more efficient than the Intel's SSE3 example - no shufpd instruction is needed.

OK. But how about the new hyper threading instructions (2)?

Simply run two clients on a 1 proceesor HT machine, or run three or four clients on a dual processor machine, this maximizes output.

I didn't look at the description of those two instructions closely. I just assumed that the OS was to use them in its idle loop.
