RE: <Isn't the latency inherent in the rambus module due to the time it takes to set up, then read 8 cells, then set up and perform a serial transfer of that parallel data?>

The serialization delay is small compared to the chip set delay.

RE: <I'm not familiar with this chip set and haven't heard of a direct connection of rambus to any chip. Are you certain that there is no memory controller between the cpu and the memory busses? Are the bus controllers integrated into the chip? Is the chip running 400MHZ through its external bus?>

Another soon to be famous chip with direct connect to rambus is Timna which will be introduced early next year as Intel's PC on a Chip. It has two directly connected rambus channels. There are internal Rambus Asic Controllers, of course, but no memory controllers external. There is no external memory bus, just the two drdram buses.
