Chuck, re: <The emperical data, however, suggests that even in point-to-point configuration, moving around 64-bits of data at 200MHz is non-trivial.>

I don't mean to say the implementation of 64-bits bus at 200MHz is trivial. I was merely comparing it to the complexity of RAMBUS implementation on the motherboards. Remember, that some on this thread laughed at the sight of regulators used on the Athlon cartridge. In my view, that was a great design decision taken by AMD to deal with high speed digital interface. Local power regulation close to the chips operating at very high speeds @ a high source/sink current(switching) capability, is a must and AMD recognized it very well. I think AMD used great local power distribution system to make the CPU cartridge insensitive to the expected variations in power supplies and variations from motherboard to motherboard. There is also another difference between ATHLON FSB and RAMBUS - no need for a socket(Northbridge chip.)

And moving 16 bits around at 800 MHz is WAY non-trivial. ;^)
