How instant? My late 2016 MBP wakes in around a second. My 2014 Mac mini usually takes only a few seconds.

As instant as in the keynote video. IIRC around the time of Lion I started seeing a progress bar as it was coming out of sleep.

Now, especially if you require password you need to wait a second or so after it wakes up, because input is no longer immediately available. And then it takes some time to actually wake up and start the window server etc.
