That is one thing AMD has done fairly well the last few years- clean up their CPU offerings so it makes sense. Especially concerning the A series APU's. The AM3 line can still be a bit confusing- but not nearly as bad as Intel.
For the A series they have the A4, A6, A8, and A10 lines. The higher the number the better the chip. Easy peasy.
Although I do have to give them a thumbs down on the numbering- it's meant to make people think it means the number of cores. But that's incorrect. The A4 is a dual core, A6 a dual or quad core, A8 and A10 both quad cores.
But, for the non-technical person, the number system does work. You just have to not think about the number of cores (besides, does it really matter when it comes right down to it?).
