Its good to see more awareness of the P6xxx processors.
They're like an "i3 Jr." Its missing Hyperthreading (like UniqueName mentioned) and Virtualization and a couple other small features.
The site UniqueName posted had both processors, and rated the Phenom II above the P6200, but didn't have benchmark numbers for the Phenom II.
The P650 is a 2.6 GHz with a 25W TDP. P6200 is 2.13 GHz 35W TDP. I normally would have thought the Phenom would run hotter... Looking at the high level stats, I would probably agree with the comparison chart showing the P650 would be stronger. Laptop performance is hard to predict, like mentioned above... Good luck!
