AMDGPU-PRO driver global memory issue

I'm testing the AMDGPU-PRO Beta driver (16.20.3) on Ubuntu 16.04 by running some OpenCL tests. The most significant issue I've noticed is that only ~680MB are available out of the 4GB of a Radeon R9-Nano. Given that only 1/4 of that can be allocated using a buffer object this proves quite restrictive.

In addition, I've observed some performance issues comparing with the fglrx 15.302.
