1. Which is a better IGP, the HD 4200 or the HD 33/3200? 2. Would the HD 33/3200 be an equivalent of a 3450 while the HD 4200 be equivalent of a 4350?
The 785G (HD4200) will have some improvements over the 780G/790GX (HD3200/3300), quoted from the Anandtech article: As the drivers have not been finalised for the 785G chipset, there are no real benchmarks yet, so it's hard to say which Radeon card it is equivalent to. But for the 780G/790GX, I think you are right, they are roughly on par with the 3450.
