Is there a difference between laptop llano's memory controllers

[Phyrexiancure]

According the amd's website the difference laptop llano models are compatable with different memory frequecies. The A8-3500M is compatable with ddr3 1333 while the A8-3510MX supports ddr3 1600. From my experience with the phenom II's memory controller anything above its supported ddr3 1333 would give diminishing returns per htz increase. I was wondering if the models of the laptop llano apu's have different memory controllers which seems so due to amd description. Or is it that the memory controllers are same and this memory support differentitation is there to be able to market the higher end apu's. The information that I want seems technical since you need to actually know what is in the chip, would there be a place on the net to find this information.

High speed memory is critical to Llano's performance . Not because of the cpu but because of the GPU .

Memory bandwidth is an important feature for graphics through put . In a discrete graphics card its memory is on the card and dedicated . For Llano the graphics memory is the system RAM . Higher speed system RAM results in quite large increases in graphics performance .

The cpu also needs information from the ram. In an am3 platform if you went past the suggest memory frequency you would see little improvements.

Is there a diminishing return for the suggested ddr3 1333 chips
