Intel has two families of CPU chips: the Pentium M line (part of
the Centrino package) and the Pentium D line (formerly Pentium 4).
M=mobile, D=desktop.

Pentium M gives more performance at a lower clockspeed than Pentium
D. So a 1.6GHZ Pentium M is roughly equivalent to a 3.2GHZ Pentium
D/Pentium 4 (give or take, it's not exact).

Celeron is the budget version of any Pentium chip. It will have lower
performance than its beefier, more expensive Pentium brother. Celeron
M is the budget version of Pentium M.

Does that help?

FYI, the big benefit of Pentium M/Centrino is battery life, less heat,
and probably a lighter laptop. I worry about the use of these desktop
CPU chips (Pentium 4/D) in laptops and would probably stay away from
them these days.

Unless you buy the highest-end laptop (desktop replacement), you will
not get a laptop as fast as a desktop anyway. The hard drive is
likely to be slower, etc.

: Thanks for the informative response.

: If it is that a 1.6Ghz Pentium M is going to give me 3Ghz P4 performance,
: then that seems fine to me and will be a step up from my Athlon 2400+.

As an addendum, note that newer versions of the Pentium 4 have
hyperthreading. On Windows XP Pro, this could help performance in
some cases as HT mimics having a 2nd CPU. The Pentium M does not have
hyperthreading at all.
