relationship to performance, so you would expect a "740" processor to be
about twice as fast as a "380" processor.
A Pentium M is based on an enhanced Pentium III (Pentium 3)
architecture, but is far more "efficient" than the Pentium 4 [The whole
detailed explanation is complex, but you can estimate that a 1X GHz
Pentium M is going to perform about the same as a 2X GHz Pentium 4, VERY
A Celeron is a Pentium or Pentium M with a lot less cache (one quarter
to one-half) and also a less efficient cache architecture (cache
associativity, technically). It's performance is less ... how much less
is application dependent, but 15% to 35% is the rough range (compared to
the equivalent "full featured" processor running at the same clock and
FSB speed). Also, Celerons have some features missing (such as
"speedstep", for example), and often lower FSB speeds (Celerons have 400
& 533 FSB speeds, while full featured processors may have 400, 533 and
800 MHz FSB speeds). The core processor, however, is identical.
