C2D is dual core…
Core2 is the better architecture though :) (i.e. over pentium)
That depends which Pentium ;)
The “Pentium Dual Core” that you see in notebooks and desktops are simply Core 2 Duo's with half the cache and (often) a slower FSB.
The real old “netburst” Pentium's - i.e. Pentium D's - are the old architecture and the horrible hot things we should never speak of again!
Basically, anything Intel that you find these days in a Dell notebook is all based on the Core 2 architecture, regardless of whether it's called a Core 2 Duo, Pentium Dual Core, or “Fuzzy Wuzzy” :)
This Dell has also been in PCWorld for at least a month now. I'm pretty sure it also lacks a HDMI - i.e. its a backward step from the 1525 - as they are probably trying to differentiate more between the Inspiron and Studio lines.
