Hi Dan3. While 10% is probably fairly accurate for a single processor P-III based system, it is probably low for both Athlon and multiprocessor systems.

Unlike most previous processors, the Athlon does not support critical word first presentation of data, therefore the latency is the entire length of the burst, which is significantly impacted by doubling the data rate. I would guess an average of 15% for Athlon in a single processor system.

Additionally, multiprocessor systems are affected significantly more than uniprocessor systems by memory bandwidth. Unfortunately, I am not sufficiently familiar with benchmarking of multiprocessor systems to hazzard a guess.
