Cómo es de suponer las empresas marean un poco la perdiz. Tener en vilo a la competencia y dar la sorpresa siempre ha sido una ventaja en estos mercados. Prescott se suponía que era el nombre técnico precisamente de los primeros Pentium 5. Llámalos Pentium 5 llámalos Prescott etc.. Son nuevas arquitecturas a tener en cuenta. El nombre comercial es una cuestión de mero marketing.
Los sockets cambian y la arquitectura con 64 bits se estima que caerá en el segundo cuarto del 2004 (8 meses aprox). Los primeros Prescott no usaran todavía dichas prestaciones...
"The essential details of the new Pentium 5 are already known today. However, it's not completely clear if the processor with the Prescott core will be called "Pentium 5" or not. The marketing strategists at Intel are still not in agreement on this point. It would make sense to stay with this nomenclature, though, since AMD will be launching the Athlon 64 a few weeks earlier..."
"..It's not just CPU-related news that we have to report: both manufacturers are working on new platforms as well, with AMD using Socket 754, and Intel, Socket 775 (Socket T, LGA construction) starting Q2 2004. Prior to that point, the Pentium 5 will make its debut on the "old" Socket 478..."
Incluso se dice que la arquitectura de 64 bits vendrá integrada pero no funcional desde el principio, al igual que el HT ya lo traían las pastillas de hace algún que otro año ...
"Rumors have it that Intel has already integrated a 64-bit extension (codenamed Yamhill) on its Prescott core, which can then be unlocked as required. This is reminiscent of the Hyper-Threading feature, which was already was integrated in the Pentium III processor hardware. In addition to the already existing command extensions such as SSE2, Prescott works with 13 new commands (PNI = Prescott New Instructions), which serve to accelerate video encoding and improve thread synchronization.."

Lo de la columna del Overclocking..
Un detalle a tener en cuenta. También he visto Pentium IV 3.06 HT overclockeados por encima de los 4.2 y es curiososo que no aparezcan sistemas como éste en la tabla.
