They have improved a bunch of things (e.g. layout algorithms) etc., so yes, the system might feel faster to you if you were using (usually poorly coded) apps where this was a factor. But its not something that you will see in a standard micro benchmark.
As you seem knowledgeable about these things, is Metal rendering of the UI enabled on dual-GPU machines now?

I think Apple said that Metal now powers the UI for all GPUs that support Metal. Why wouldn't it be the case for you?
His question make more sense now, I was thinking why Apple need to do that, because the GUI is not that demanding, and don't need that much GPU power.
I may be wrong also. I'm sure I've read that in sierra, Metal would power the UI for all supported Macs, but I can't find that piece of information anymore.
Yes, I've read that somewhere but can't find the source, I'd assumed it was in a post by leman I imagine it is in a WWDC video somewhere...
If it is I have no idea how we test it. IIRC in El Capitan, only some machines accelerated the UI with Metal, even if other machines (like dual_GPU laptops) that supported Metal didn't used Metal for the 10.11 UI. I don't think there are good benchmarks for the UI, and does Quartz Debug still work when using Metal for the UI?
Unlikely there is even a need for a second GPU to render the GUI.I am running 2x HD7950 in my Mac Pro. From my observation, the answer is NO. if there is any test I can do for you, please let me know the details on how to carry out the test.
