Subject: Effect of RAM speed on engine play

I believe I saw a thread a long time ago on the Winboard forum where Robert
Hyatt was discussing this, but I can't find it.

Given equivalent CPU capabilities, would an engine on a machine with one of the
new 800MHz P4 QDR buses get a large or small or non-existent boost in speed over
standard DDR at say, 266MHz? or even SDRAM at 100/133?

My 533MHz QDR operates at the same frequency as even old PC133 SDRAM memory, but
it delivers 4x as much data at each interval. Is the base frequency of the RAM
more important, or the amount of data overall?
