Because that is hella expensive. They would be far better-off using separate memory controllers for the GPU and CPU portions of the die. 384-512MB of GDDR5 framebuffer on a 64-96 bit bus, anyone?
Nope, both CPU and iGPU will use the same Memory Controllers. I believe the next step will be DDR-4.
Also, Trinity can operate with up to 2133MHz memory dimms
