The Trinity A4-5300 APU by itself is at best adequate for playing games at low resolution (1366x768 or lower) and low graphics quality or medium graphics quality depending on how demanding the game's graphics are.
Overall, the integrated Radeon HD 7480D graphics core is somewhere between the performance of a Radeon HD 5450 and HD 5570. I suppose you can say it is likely to be slightly faster than a Radeon HD 6450.
