Since the release of Ashes of the Singularity, a lot of controversy surrounded AMD’s spectacular results over NVIDIA’s underwhelming ones. Was this DX12 benchmark gimped in order to run faster on AMD’s hardware? Apparently not as Overclock.net‘s member ‘Mahigan’ shed some light on why there are so dramatic differences between AMD’s and NVIDIA’s results.

What’s also interesting here is that Mahigan has provided a number of slides to back up his claims (which is precisely why we believe this explanation is legit).

As Mahigan pointed out, Maxwell’s Asychronous Thread Warp can queue up 31 Compute tasks and 1 Graphic task, whereas AMD’s GCN 1.1/1.2 is composed of 8 Asynchronous Compute Engines (each able to queue 8 Compute tasks for a total of 64 coupled) with 1 Graphic task by the Graphic Command Processor.
