Maverick - AMD's 3DNOW seems to be losing support with the software developers.

Did you know some ISV's think Katmai New Instructions are superior to the 3DNOW?

I didn't think you knew.

So I'll refer you to the article so you can read for your self.

{=================================}
eet.com

"Another potential consumer of execution units is SIMD
processing. Jalapeno will have to face Intel processors
equipped with the Katmai New Instructions (KNI), Intel's
second-generation version of MMX. Cyrix is in the process
of deciding whether it will remain with the 3DNow
instruction-set extensions of Advanced Micro Devices Inc.
(AMD), or move to an implementation of KNI.

"We've heard from some ISVs [independent software
vendors] that KNI is superior to 3DNow, Swearingen said.
"There's discussion on whether AMD intends to evolve
3DNow in that direction, and on whether we might go there
independently. One of the issues is that KNI may use 128-bit
registers and some other things that you can't just adapt to
with some simple pipeline changes. We are still looking into
the question."

{===========================}

Wouldn't it be downright awful if the K6-2 and K6-3 became orphan chips because they didn't support Katmai New Instructions?

That could be a real long term problem for AMD, don't you think, Maverick - especially if Cyrix doesn't support 3DNOW.
