Probably not much point co-operating. The *internals* of AMD chips and
Intel chips are very different. I suspect both of them have a RISC core
with an x86 instruction set interpretation layer, but that's where the
similarities end ...

Bit like expecting a turbo-prop engine company to co-ordinate their
designs with a piston engine company. The two engines might look very
similar on the outside, but the internal machinery bears no resemblance
whatsoever one to the other.
