Very impressive, can't wait to see the 1070 and the radeon 400 series added to the lineup for a comparison.

But one question, did you do the benchmarks in an open or closed rig?
I'm aware that GTX 1080 runs into throttling quicker than it's predecessors, and usually quickly falls down to it's base frequency within 2-4 minutes of load. So to get reproducible results the card should have a "warm up" before the benchmark itself, or run multiple times.Michael Larabel

About the open driver on AMD i rather see the open drivers since that's what i use but some might say that it would be more fair test if tested with amd blob.Michael Larabel

Great, thanks. This might actually work out well since the next amdgpu hybrid driver should be coming out fairly soon.
Great to hear a new hybrid will be coming out soon.... Can't wait to run some fresh tests!Michael Larabel

Any compute device that has preemptive multithreading has asynchronous capabilities by definition. In the Pascal generation, NVidia has introduced much finer-grained preemption, so it's ability to handle asynchronous instructions has improved substantially. Is the hardware support as effective as AMD's implementation with their ACE's? Well, that's another argument for another day, and I don't know the answer. My guess in some cases it will be better, and other cases, like an-AMD-funded-and-biased-benchmark-posing-as-real-game-aka-AOTS, it will not. So it's fair to say the AMD have used a different means to support asynchronous compute, and even to argue that it's better. But to say NV doesn't "have" it is incorrect.
Also, remember that AMD may have paid a huge price for those ACE engines. Notice how the latest NV hardware gets 1.8GHz on air, while the Vega is pegged at 1.2GHz. It's like CISC vs. RISC. Yes, AMD may have better hardware implementation of complex logic, but all that overhead may require sacrifices in clock speed, ROPs[1], etc. that in the end result in poorer performance for most use cases. Look at the apps you want to run on your OS and then the performance of your card for those apps, *then* buy your card. If I were to use simple-minded metrics like "it ain't got no async_compute like AMD" I would have a Fury X which provides less than half the performance of my GTX980Ti at the same price and many times the number of headaches. Yeah, no thanks.
EDIT:
[1] It appears Vega has only 64 ROPs, same as the Fury X. The GM204 products have 96 ROPs; the GP102 products (1080Ti, Titan P?) will probably have a similar number.
