It is likely that neither is profitable for you, because ASIC miners are alot more effective than any GPU mining, which in turn is alot faster than CPU mining. But don't take my word for it. This hardware comparison wiki is a good source to make an initial estimate. There is one entry listing the combination of an A10 and a HD7660G GPU, claiming to get 105 MHash/s just from the graphics card (and not listing any value for the CPU).
If that doesn't deter you---at 100 MHash/s you are looking at an expected average reward of less than a dollar per month, probably less than the electricity your computer needs is worth---please consider updating that wiki with the performance you are getting.
Bitcoin mining with either CPU or GPU looses money on account of the amount you spend on power is greater then your expected returns. GPU mining is still profitable for mining some alt-coins such as litecoin but likewise CPU mining losses money in these instances as well.
So if your interested in getting started mining, I would recommend GPU mining either feather coin or litecoin. Anything else will likely loose you money.
