How is Rambus better than DRAM?

0

First off, Rambus provides far higher bandwidth per pin than any other solution available today. This has many related benefits, the first is that high performance memory systems can be built from small numbers of RDRAMs. The PS2 for example, employs two Rambus channels each with a single RDRAM for a total of 3.2GB. At the system level, the reduced pin count offered by RDRAMs results in fewer traces to route on the motherboard, fewer motherboard layers, and the ability to scale bandwidth by adding channels in parallel. These features allow price and performance to be balanced to meet the needs of a particular system. As computing systems continue to undergo greater levels of integration, the high bandwidth and low latency of RDRAM will enable new computing paradigms or unified memory architecture (UMA) systems. A good example is the Nintendo 64, which used a previous generation Rambus product.
