It really confuses me, i found 3 laptops 2 of them has R530M, one of them has A12 cpu other one has A9 but the Radeon 530 one has A9 and much more expensive. Im just confused.

Here's all:
1st laptop(most expensive)
4GB Ram
CPU:AMD A9-9425 3.10 Ghz
GPU:Radeon 530 2GB
1TB
2nd(in the middle)
8GB Ram
CPU:AMD A12-9720 2.7 Ghz
GPU:AMD Radeon HD R530M 2GB
1TB
3rd(cheapest)
4GB Ram
CPU:A9-9420 3.0 Ghz
GPU:AMD Radeon HD R530M 2GB
1TB

Other informations are literally exactly the same.
