I know that memory latency is being reduced as memory runs on a faster FSB. So... I am curious. Is the speed increase on the P4 533 with PC1066 mostly due to the increased bandwidth or is it mostly due to the lower latency, or is it a pretty even combination?
Idealy, someone could test it by running 4 sets of benchmarks. P4 400FSB with PC800, P4 533 FSB with PC1066 only 3x clocked (IE, at 800 (2 x 133 x 3)), P4 533 fsb with PC1066 clocked normaly, and (not sure if you can do this one) P4 400 FSB with PC1066 clocked at 5xFSB (2 x 100 x 5, close to 1066, not quite).
Just a curious thought, and wondered if anyone had tried that before.

Well Latency is mesured in clock cycles (CL and a buncha others... look in the BIOS) and Bandwidth is also with clock cycles... the only reason you would get increase only from bandwidth is with dual channel... but im not sure on this, just a speculation. Anyways a clock increase to the ram should increase performance because of the smaller latency and the higher transfer... so there
