One of the papers that surfaced was dealing with a new cache scheme for GPU's issued by AMD:

One of the writers, Mohamed Assem Ibrahim, explains how this will work:


This looks to be very promising with some incredible IPC gains of 22% up to 52% and 49% energy savings. Worth a read through and look.

Very good comparison with the baking example.
I think given AMD's knowledge of chip operation and specifically cache use, they'll be able to pull this off very well.
As long as they can get the drivers to work properly, I cannot see any reason why this won't be a hit.
I'm extremely excited to see how this will improve GPU performance.
It looks very good.

This should really help the Series S to be a descent performer if it uses the same tech.
