No such thing as a a8 7600k so I'm guessing you mean 7600, where as the 7860 is a 7860k obviously the a10-7860k is better, it's unlocked so you can overclock it. Both these CPU's have the same integrated graphics so graphics wise the same, They have the same shitty IPC (Instructions per clock) so they will both do pretty bad tbh lol. But the a10 is better yes by a bit.
