XB1 GPU Has 8 Graphics Contexts, Uses Multiple GPU Command Streams To Reduce CPU-GPU Latency

Actually a lot of this known or is common sense and the PS4 is similar due to the SOC being essentially the same GPU architecture. Sure one is more powerful, but don't expect AMD to reinvent the wheel with each system.... heck they are both even based on existing PC GPUs.

...

Although the PS4 has what was it 8 ACE units with 64 queues total compared to Xbox one's only 2 ACE units with 16 queues.

Yes that is correct. The queues are responsible for organizing and scheduling computational tasks for the GPU commonly associated with CPU. This, in addition to the raw horsepower advantage of the extra GCN cores is most likely responsible for the huge disparity in general purpose calculation power described in Ubisoft's presentation from August. 

 

It also explains why Microstructure came out last week saying that Compute on Xbox One was being improved with SDK update. It's definitely something they know is important and they want to make their system more efficient at it.
