What It Shares With The Pentium 4
Both processors use a very similar bus protocol. The maximum frequency of the P4's front side bus is 200 MHz, while that of the Pentium M currently tops out at 133 MHz. In both cases, information is transferred four times per clock cycle, which is called quad data rate or QDR; Intel calls this a quad-pumped bus. The core voltages are also nearly identical: the P4 Prescott requires 1.4 V while the Pentium M Dothan runs at 1.35 V.

The increasing thermal dissipation makes it obvious why FSB533 is the upper limit in the notebook sector.
