If ur budget is not hig and u can't afford a i5 CPU + GT 640M/740M/750M or HD 7670M/8750M laptop, definitely u should go for A8/A10 'cause APU's iGP HD 7640G/7660G is far better off than Intel's HD 4000, better to go w/ A8/A10+7670M so that dual graphic could set up and in best case scenario dual graphics performs better than GT 640m DDR3 and slightly below GT 650M DDR3. But if u go for APU, remember u should have more than 6GB RAM and dual channel memory should be activated 'cause APU's iGP depends much on system's memory.
But if ur budget is over 700 bucks, definitely go for i5 + GT 640M/650M or be better off, AMD's solution is more for budget.
Here is some reference:
