Hi!
AMD published details about it's plans for "SSE5" instruction set extensions for it's 2nd generation of Barcelona, expected not earlier than in 2009 (so no need to hurry, Akos :-) ):

Oh, yes...
SSE5 has a really good feature. There are four-operand instructions!
But only with one memory operand, of course...
...and some crazy instructions too.
eg.: PHADDBQ (Packed Horizontal Add Signed Byte to Signed Quadword)
It does exactly 14 additions. Really crazy. :)

It's strange that things like y := a*x +b in a single vector instruction did not appear earlier in Intel FPUs.

BTW, Akos, you are seriously overclocking your equipment, right?
Did you ever experience a fault that looks like the one quoted here by overclocking a bit too much? This is a faily common one, and one of those bugs that "just can't happen" if the code were according to the specs. But maybe you are already familiar with the prob.

I predict chaos when AMD and Intel both have mutually incompatable "SSE5" instruction sets.
After the extended go around over the 80486 moniker back in the 90's though I'm surprised that Intel was willing to use a name that they couldn't control for their x86 extentions.

Yeah, same goes for the two companies take on virtualization.
The both want to "set the standard", making life difficult for software developers.

Thereby following hot in the footsteps of choices like CD+R, CD-R, DVD+R, DVD-R, DVD-RAM, DL DVD+R, DL DVD-R, HD DVD and Blu-Ray. What standard? ;-)

No problem with compatibility, AMDs x86 license gives Intel the right to use any x86 extension AMD might come up with.

Hey, Intel runs AMD's x86-64 just fine, doesn't it? ;-)
RE: Hey, Intel runs AMD's

And that should be also so for Intel Compiler compiled code for AMDs... Except for Naughty Intel...
(Personally, I think that STINKS.)
Beware Intel's compiler!

Im not paranoid enough to think intel deliberately crippled the compiler for AMD, i mean, how much work would THAT be, and could it even be done without losing lots of optimalization for their own processors? To both optimize for their own and at the same time do maximum damage for AMD, thats not realistic at all, but im sure they see it as a nice bonus that it runs so bad on AMDs, same as AMD would if the positions were reversed.
