@ 2004/08/25The Prescott is the third generation of Intel Pentium 4 processors. Released after some delays during the first quarter of 2004, the Prescott P-4 is based on a 90 nm core compared to the 130 nm core of the Northwood or the 180 nm core of the Willamette.
To achieve this latest core shrink, Intel implemented a new "strained silicon" technology. This article is not going into much detail of the Prescott architecture, but basically Intel is using smaller gate lengths, longer execution pipelines and about twice as many transistors as compared to the Northwood. Some other significant differences worth noting: the L1 cache was increased from 8k to 16k, the L2 cache jumped from 512k to 1024k, and default vcore voltage was reduced.
