Not quite related, but I read a paper that said that AMD basically has
created their own very powerful CPU, and the Intel ISA is actually a
hardware emulation on top of that.

It seems to me that AMD could release their own CPU by removing that
layer without a tremendous engineering effort.

Is this the same HyperTransport that VIA and AMD are using on the AMD64
motherboards?

For example, my motherboard has one HyperTransport link between CPU and
the northbridge, 16-bits at N GHz (can't remember right this moment), so
it can move quite a bit of data.

I read a spec sheet and it said that HyperTransport can be 8-16 bits
wide, and listed several operating speeds, with more coming in the
future.

Also in the future:

    - links for more than just CPU and northbridge
    - a cross-bar like system to connect components with HT
    - other goodies I can't remember

If this actually pans out, maybe the PC will finally get some rational
I/O on the motherboard.
