Dothan Over Netburst: Is The Pentium 4 A Dead End?

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.

All Pentium M processors include support for MMX, SSE and SSE 2. The SSE 3 instruction set will only be incorporated into the next processor generation, as will the EM64T extension (Extended Memory 64 Technology) that is required for use with Windows XP x64 Edition.
