RAMBUS has less bandwidth than DDR using a single channel (RAMBUS=800MB/s while DDR=2.1GB/s). The advantage is that RAMBUS is used in a four channel setup (4x800MB/s=3.2GB/s) thus giving its greater bandwidth. nForce, due out soon I hope, uses a dual-DDR channel (2x2.1GB/s=4.2GB/s) so it will have more bandwidth to toy with than current RAMBUS solutions. I wish Intel and AMD could be put in a identical board, then bench the bitches to see who is king :8 Btw, I do have an old AMD chip (K5 233MHz) running in a Intel 430TX - runs great for its speed, no stability problems at all - even the old AMD shit runs fine if placed in a descent motherboard! The motherboard is the key to a stable system (well one of the BIG factors).
