Question about processing speed on AutoCAD.... Intel P4 vs Intel Centrino

[Jesús Padilla]

Intel P4 or Centrino for a Notebook using AutoCAD...

Actually I use a desktop computer with Pentium 4 2.4Ghz / 512MB RAM / Win XPPro. This computer works fine for me.

I want to buy a new notebook. In my country the most common options are:
1.- Intel P4 2.2 Ghz.
2.- Intel Centrino 1.4Ghz.

The question is:
How fast is the processor Intel Centrino using AutoCAD? or Is the Intel Centrino faster than Pentium 4 using AutoCAD?

I know the Centrino features, Intel says "Centrino is faster". I need to know the experience of the users.

Thanks.
