I currently have a P4 630 3GHz and I want to know what the eqivalent Core 2 Duo speed is, or are they all faster?

Is a 1.6 C2D quicker than a P4 3GHz?

They are all quicker - you can compare various models here http://www23.tomshardware.com/cpu.html

Thanks for that quick reply.
In very crude terms, a dual core 'Core 2 Duo' is roughly twice as fast as a Dual core 'Pentium D' at any given clock rate.
So a 1.6Ghz Core 2 Duo, would be comparible with a 3.2ghz P4D.
In single threaded apps, the P4, and P4D performance is virtually the same, of course in multithreaded apps where your using both processor cores, the dual core chips (be it P4D, or Core2 Duo) both outperform the single core Pentium 4's. (IE the C2D is still about twice as fast as a P4D in multithreaded apps, with both cores fully loaded.)
