The 820M is barely any better than the integrated GT2 and only comes with slow-clocked DDR3. I don't know if it's worse than the 7640G, but certainly not much better. Any more modern AMD Laptop APU like the A10 7300 should beat that easely if coupled to DDR3-1866
However, for that price, you won't find much better than that
