async and ACE are two different things. Nvidia may not have HW ACEs in maxwell but this doesn't mean that they can't do async compute.
It's also silly to assume that this is some super all important feature for dx12. This is a feature that may help get extra performance out of GCN. AMD has been talking it up and it could be way more useful to their architecture.
I don't think nvidia has put a lot of time or emphasis on this because they already get high utilization out of their architectures. There may not be the opportunity to gain on maxwell but this may not be the bad thing that people are trying so hard to make it out to be. Nvidia seems to be able to get a lot more performance out of their architectures than AMD, just look at the theoretical performance figures. At the end of the day, it is all about how well you can utilize your HW, that is all that ultimately matters. And so far, nvidia has done this very well.
We will see if async is this magical ability that makes GCN amassing but its always wait and see with AMD......and it seldom lives up to the hype. Why do you believe this will be any different? Cause I am a believer when I see it. And this small time developer with close ties to AMD, their ashes benchmark was once used by AMD to show off mantel. Look up the YouTube video. This thing has been converted to dx12 but no wonders.......it runs great on GCN. This developer has a marketing agreement with AMD. This should be all you need to know.
We will see how much asyn helps GCN when real games come out
