Rendering After Every Speed Ramp (or Effect) in PP 2020 ?

exact same problem... it used to work then all of a sudden i can't play back a "speed-ramped" clip on this same project. even after hitting render and having the green progress line... the clip is about 5 seconds and only half way through it it moves one frame forward but that's it. (16gb ram macbook pro from 2018 - SSD drive)

Same exact problem here. Only difference is that Im editing off the hard drive. 

For better or worse, Premiere 2020 needs a bit more hardware than earlier versions. And looking at your rig ... a slow-Ghz CPU with only four cores, and using an external drive ... not much oomph there.

And I'd agree with Ann ... unless that's say a Samsung T5 via Thunderbolt or something about as "hot" in sustained read/write, that external drive is not helping things either.

To your first question, some will, many won't, as like many things ... it depends.

What is the media you're using? What other effects if any? And what is your hardware ... OS/CPU/RAM/GPU/vRAM ... and is the media itself on internal or external storage?

All of the above ... and some other things ... can affect this. So it's useful to know as otherwise we can only make random guesses. In troubleshooting one always starts with the things that are most commonly a possible fault. And works up from there.
