Next Pentium 4 core - Northwood - was a die shrink of Willamette core. Based on 0.13 micron technology, Northwood microprocessors had lower voltage, and, as a result, lower power consumption than Willamette CPUs. The size of level 2 (L2) cache in this core was increased to 512 KB, besides that there were no major changes in microprocessor microarchitecture. Bigger L2 cache gave Northwood processors 5% - 20% speed boost over Willamette processors. Front-side bus frequency in first Northwood microprocessors didn't change. Over time the bus frequency was increased to 533 MHz, and finally to 800 MHz.

The final revision of the Pentium 4 was Cedar Mill, released in early 2006. This was simply a straight shrink of the 600-series core to 65nm, with no real feature additions. Cedar Mill solved the heat problems of Prescott, with a TDP of 86W. It has a 65nm core and features a 31-stage pipeline (just like Prescott), 800MT/s FSB, EM64T, HyperThreading and Virtualization Technology. As with Prescott 2M, Cedar Mill ... has 2MiB of L2 cache. It was released as Pentium 6x1 and 6x3 at frequencies from 3.0GHz up to 3.6GHz.

The original Pentium microprocessor had the internal code name P5, and was a pipelined in-order superscalar microprocessor. This was followed by the P54C, a compaction which was dual-processor ready. Subsequently, the P55C was released as the Pentium with MMX Technology (usually just called Pentium MMX); it was based on the P5 core, but had significant changes for MMX and improved instruction decoding.

The original Pentium microprocessor had the internal code name P5 and the product code 80501 (80500 for the earliest steppings). This was a pipelined in-order superscalar microprocessor, produced using a 0.8 µm process. It was followed by the P54C (80502), a shrink of the P5 to a 0.6 µm process, which was dual-processor ready and had an internal clock speed different from the front side bus (it's much more difficult to increase the bus speed than to increase the internal clock). In turn, the P54C was followed by the P54CS, which used a 0.35 µm process.

Pentium MMX and non-MMX overdrive processors look somewhat similar to boxed Pentium processors. Like the boxed processors, the overdrives have processor markings on the heatsink. Unlike the boxed processor, the overdrive CPUs have speed marked in the top right corner. The overdrives ... include integrated voltage regulator, which allows the microprocessor to work in socket 5 motherboards. And finally, the overdrive processor have their clock multiplier locked. For PODPMT60X180 the clock multiplier is locked at 3x, so depending on bus speed (50 or 60 MHz) the processor will run on 150 or 180 MHz.

Dell plans to release Pentium-M laptops across their entire Latitude product line. Along with the movement to the new chip technology, Dell is ... revising their enclosures and their removable drive module size - the first time in many years. For the initial round of releases, Dell has announced (from smallest to largest):
