Guys, i found out that AMD P320 is among the popular AMD mobile CPU at the moment. Since almost all brand of laptop are using that processor for their AMD based laptop. How does this processor fared compare to i3 in terms of speed if both laptop do dedicated graphic.

I'm wondering how far clock speed plays the role in photo editing? Because I had a desktop with AMD dual core 2.8Ghz and 4GB of RAM it will take sometime to process when it comes to photo editing. My new and coming laptop i was planning to get a budget 1 but able to process a photo with a decent time not too fast and not too slow. Should i get for a P320 couple with ati5470? or i3 couple with 310m?
