Tenchusatsu,

Thanks for the reply.

On the other hand, I really don't think dual-channel DDR can easily be implemented with just a 6-layer motherboard. That leaves RDRAM with a big advantage once the Willamette/Tehama platform rolls around.

Willamette/Foster will at least be able to to use the additional bandwidth offered by Rambus, and dual RDRAM implementations. This still leaves me confused (as I posted earlier) why Intel would prefer DDR to Rambus in the server area, where bandwidth is very important.

RDRAM may in fact provide tangible benefits for Willy/Foster, but I am still scratching my head as to why would Intel push it to Coppermine and hedge on Foster.

Regarding Athlon, I am not sure if the dual DDR will be necessary. The single channel provides all the bandwidth the (future) Athlon chip is able to receive: 133 MHz x 8 bytes x 2 = 2.1 GB/s. Current Athlons on DDR platform are limited to DDR 200 anyway, with bandwidth of 1.6 GB/s. Which incidentally matches a single RDRAM channel. ;-)
