Re: Because the width of the RDRAM channel is limited, it must pump 4 16-bit words to fill the 64-bit word that the processor is expecting...

He's sort of getting it. Rambus, even dual channel rambus, is too narrow a bus for modern processors. Do you realize that, internally, coppermine has a 128 bit wide connection between the core and the cache? Dual DDR would be a perfect match for Coppermine. Dual Rambus isn't, and single Rambus is worse (as shown by benchmarks).

Willamette will have an internal bus at least as wide as Coppermine. That's why the volume chipset for Willamette (Tulloch) isn't going to be stuck with Rambus.
