Even in the past Motorola CPU's had IMHO the "better" designs.
6502 versus 8080 or 68000 versus the "awful" 8086.
Unfortunately, for what reasons ever, i allways programmed for Intel/AMD cpus.

Thanks to AMD64 my "sympathy gap" between Intel/AMD and Motorola/IBM becomes
narrower.

Yes, it looks Altivec SIMD instructions are much more consistent than Intel's
SIMD instructions:

http://www.simdtech.org/apps/group_public/download.php/26/Altivec%20formatted.1.2.pdf

What kind of algorithms did you try with Altivec?
Did you tried Kogge-Stone sliding attack getters?
What about a bit[64]*short[64] or bit[64]*byte[64] dot products?

Thanks,
Gerd
