Rambus no benefit on servers

One last comment on rambus - then I promise I'll stop. It's been argued that rambus may have longer latency, but it's better on servers because it can stream data instead of bursting data with pauses in between.

If you spec out a multiprocessor server, you'll see that the SDRAM has to be added in sets of 4. That's to 4 way interleave the memory so that by the time the controller gets around to each DIMM, it's ready to provide data.

As a technology for high end servers, rambus has no advantage in terms of streaming data, and has a performance penalty due to latency.

A server using 4 way interleaved DDRSDRAM 266 will have a significant advantage over one using DRDRAM... and both technologies are shipping in the same time frame.
