The 7660G is the integrated graphics processor found on the AMD Trinity A10 series of APUs. It's "discrete class" because the graphics performance is more in line with what you would get out of a dedicated GPU, rather than a traditional integrated graphics chip.
my old lap top is an AMD Radeon 5650 and I play at good graphics level in 25 man raid my fps ranges from 45-60, would the AMD Radeon HD 7660G be able to mop at the same level?
