[la domanda è: Pentium M 4 e Pentium 4 sono la stessa cosa?]
pensavo due anni fa di aver acquistato un pc dotato di processore Pentium 4, come suggeritomi da un amico e come richiesto al negoziante (non
sapevo neppure cosa volesse dire 'Pentium 4', ma mi era stato detto, giustamente, di non prendere un processore inferiore)
dal manuale utente Toshiba Satellite 2410:
Processore
Incorporato
...
I computer Satellite Serie 2410 sono equipaggiati con un processore Intel Pentium che incorpora
un coprocessore matematico, una memoria cache di primo livello da 20 kb e una memoria cache
di secondo livello da 512 kb.
* Processore Intel Pentium Mobile 4 da 2,0 Ghz - M, con tecnologia avanzata Enhanced Intel
SpeedStep
ora mi è venuto qualche dubbio: ma è veramente un Pentium 4?
leggendo qua e là, vengo a sapere or ora di una tecnologia 'Intel Pentium M Processor' che, dal 2003, supporta in particolar modo i portatili
(maggiore efficacia batteria, networking wireless e altro)
ma quel 4 dopo il Mobile? come devo interpretarlo?
forse ho effettivamente un Pentium 4, solo dotato di una tecnologia un po' più avanzata ('Mobile') in funzione dei portatili?
se sì, me ne date una conferma?
vi posto intanto un reporting fatto con CPUInfo (v.2.1.3)
