[Bf-cycles] Bottleneck of gpu render

[Brecht Van Lommel]

There are various possibilities:

* Memory and texture memory read/write bottlenecks
* Different Mhz for cores
* Different GPU architecture
* Not all cores occupied due to divergence or mismatched batch sizes
* CPU Overhead

There's too many interacting parts to be sure without closely investigating.
