It might slightly outperform one using an Intel video. However, it still is an integrated video circuit inside the processor which means it will use the same memory as the entire computer. For video use that type of memory is very slow.
It has also been known for a while that certain AMD processors can't run AH using the maximum amount of cores, but I don't know whether or not that were true in this case.
The main reason I believe it would be better than an Intel chip is the way it understands the commanding code. See, Intel video understands the code in a different way compared to the "real" video cards by AMD and Nvidia.
The baseline for a video card has been said to be a GeForce 9800 GTX. Radeon R6 score is one third lower in

Shortly: Don't bother.
