"Correction: DDR-DRAM is much faster then Rambus. 100MHz DDR-DRAM
has bandwidth of 1.6GB/s, same as Rambus. 133MHz DDR-DRAM has a
bandwidth of 2.1 GB/s (that's giga *bytes*, btw, not bits).
DDR-DRAM, as well as regular SDRAM, also have a significantly
lower latency."
"There's a lot of noise made about the various merits of memory
types - my personal take on it is that it's mostly a wash, RamBus
drams do have some advantages - but for main memory systems they
are more in the future (and revolve around how many chips it
takes to make a minimum memory sized system as memory continues
to move down the memory density curve.."
