Recommendation
1.The APU in the A55 platform delivers a discrete-class of graphics performance
and enables leading GPU compute capability
-Adding a discrete GPU is optional to extend graphics and GPU compute capacity
2.For optimal performance uplift, AMD recommends Dual Graphics (CrossFire
Technology) combinations of
-A4 and Discrete GPU model Radeon HD6450
-A6 and Discrete GPU model Radeon HD6570
-A8 and Discrete GPU model Radeon HD6570 or HD6670
3.AMD recommends a balanced system memory configuration of at least 4GB of
1333-DDR3 (2GB x 2GB).
Single channel and unbalanced memory configuration can promise both APU and
Dual Graphics performance.
