I was wondering if anyone could explain the basic difference between the types of processing units within computers.

Whilst you can obviously compare the power e.g. 2.0ghz, 2.4ghz, is there any difference in performance and quality between say a Pentium, Celeron, Dual Core, Core Duo etc?

Try Pentium 4, 300+ ghz

I have had this for 3 years now.

There must be better by now.

Celeron, Dual Core, didn't impress.

Here is a performance comparison chart for a multitude of CPUs.
