Is a 2.0GB Duel Core Duo better than a 2.6GB Pentium D?

I want to know if my new Laptop can run Assassins Creed.

It lists the minimum CPU as a 2.6 Pentium D, but recommends a 2.2 Duel Core Duo. Will my 2.0 Duel Core Duo meet the minimum requirements? Those recommendations don't make sense to me unless a Duel Core Duo is better than a Pentium D.

System Requirements Wikipedia (same as listed at Ubisoft site)

yES, it's almost 2 times better.f-a-d-3

Cool. Thanks.
