Cedar Mill, the last single-core Pentium 4 core, was built on 0.065
micron technology. Micro-architecture of this core didn't change from
previous Prescott core, therefore in all tests they perform the same
as Pentium 4 Prescott CPUs. The main and only advantage of Cedar
Mill processors over Prescott processors is their lower power
consumption. For instance, Pentium 4 Cedar Mill 3.6 GHz has 30 Watt
lower Thermal Design Power (TDP) than Pentium 4 Prescott 3.6 GHz.
To distinguish Cedar Mill CPUs from Prescott CPUs with the same
features, Intel added 1 to their model numbers. Thus, Pentium 4 631,
641, 651 and 661 are 0.065 micron microprocessors, while Pentium 630,
640, 650 and 660 respectively are their 0.09 micron equivalents.
Pentium 4 Cedar Mill microprocessors were manufactured only in
775-land FC-LGA (socket 775) package.

Northwood and Prescott Pentium 4s, please see
