This is interesting to read- For me Logic is the lightest on CPU of all the DAWs I use. (Ableton 11, FL Studio, Reason 12,UAD Luna, Cubase 10.5) on my iMac pro (base model 8 core Xeon with 32gb ram)
Ableton, while it is my main daw and by far my favorite, is pretty CPU heavy as of Version 11.(10 was not quite as bad) The others are more or less similar in performance in terms of track count and latency. Ableton is completely usable but I usually start having to freeze tracks as the track count hits ~24ish depending on what plugins Im using.
With Logic, I can usually get closer to 2x that amount, but I should probably do a more apples to apples comparison.
I do have my eyes on the Mac Studio as my next Audio computer, but Im hoping to stretch my iMac Pros lifespan closer to the 10 year mark if I can...
