From what I know now, A10 is supposed to be about the power of i3 of Intel in terms of CPU power, and about the power of nVIDIA GeForce 9600GT in terms of GPU power.
Thats not enough power to do anything...
Most likely, as it is AMD stuff, Sony will implement Hybrid CrossFireX to have the APU working with a dedicated GPU, which is not on the article. There is just no way they can pull it off without another dedicated GPU with A10 alone.
Though, it seems like that the article is suggesting that the PS4 is basically a modified PC (just like how original Xbox used to be), so it may be easier for developers to make games that are easily compatible between console and PC. That may actually be a good news for PC gamers, even if they are not interested in purchasing PS4.
