Yo pensaba que el P4EE era el Pentium4 EditionEspecial.
El Prescott ademas es otra tecnologia, .09micras y mas de 100millones de transitores y el cache.
El anuncio de Intel de que su próximo procesador (Prescott) usará un nuevo conjunto de voltajes ha sembrado la polémica entre los fabricantes, pues muchos aseguran que sus placas madre actuales son compatibles con el futuro procesador cuando todavía no se han publicado las especificaciones exactas.

Prescott, the next-generation IA-32 processor, uses these and other ideas to overcome many of the current issues in scaling. Prescott's innovations include:
An updated Intel NetBurst Microarchitecture yielding higher frequency and raw performance. This microarchitecture includes larger on-die caches. For instance, a 1MB Level 2 Advanced Transfer Cache allows the transfer of more data on each core clock, delivering a much higher data throughput channel. This is especially important in a HT Technology-enabled processor like Prescott. In these cases, two threads are running on one processor and consequently need more cache space.
Improved Hyper-Threading Technology, including important enhancements to this innovation that make a single processor act like multiple processors to the operating system.
13 new processor instructions designed to improve performance for special application areas such as media and gaming. These instructions are grouped into five areas: floating point to integer conversions, complex arithmetic, video encoding, SIMD floating point using AOS format and thread synchronization.
Better clock distribution up to four times better than the previous desktop platform based on the Intel NetBurst architecture. This in part helps Prescott scale to the 4-5GHz range.
A new 90nm process using strained silicon technology that enables faster gate length scaling as well as faster electron flow through the gates.
Seven layers of low-k copper interconnect, featuring a new carbon-doped oxide dielectric material that reduces wire-to-wire capacitance, enabling Intel to increase signal speed inside the chip and reduce chip power consumption.
