I can run 16 tracks just like @Samuel84 . However, I don't think that the test is completely valid as all it focuses on is track playback. It goes without saying that the more cores you have the higher the track count will be. I'm less concerned with track count as I am eliminating individual core spikes/load. In my case the first thread of the first core is exhibiting a significantly higher load than the rest of the cores. In fact if you take a closer look, my first core is going crazy while the 3-4 threads right next to it are doing nothing. I get that a lot of this has to do with how efficient the plug-in code is and that's fine. Those issues I can deal with, I can't figure out whether multi-core plug-ins whose companies have rock solid reputation are mis-utilizing the CPU resources or where my hack isn't running as efficiently as I expect it to, especially when you compare it to the video I include.
So what plugins do you use beside logic factory ones? When i have them all upload your complete project incl. samples and everything and i could run it on my maschine...

@luckyal @Samuel84 you have comparable Z390/i9 systems. Can you both test the KGP Logic project with the same buffer & samplerate and see how many tracks you can play without the overload message popping up? Should be about the same.
I used 44.1 and luckyal as well i guess

I've seen the lopsided core load since day 1 of the multicore CPU's. Thread distribution has improved a lot, but I can still get the overload message/crackles by playing chords on just 1 rec enabled mega-heavy VI and a small buffer.
Core load is not entirely repeatable either, enabling rec, inserting another plug in, they all change the distribution.

Mac/PC/Hack. They all have this. The last time I compared(with Cubase) a properly configured Windows 10/PC was best.

A Z390/i9 upgrade looks worthwhile, BTW. No way I can afford an i9 iMac.

On the other hand, I can do what I need to do with my current build.

Utilization sucks, max power is far from 91 W rated, temps are marginally over idle and never gets to low power mode.
Native CPU PM is not working
See macOS Native CPU/IGPU Power Management
Yeah, maybe the project I shared wasn't the best example, but that was a real world one. Here's a more synthetic one but puts a load on all cores. See IPG results now.

My mistake, assumed Post #56 was Profile/7700K. Recognize both IPGs are 9900K
137W with 60% utilization is quite poor efficiency
CPU always in Turbo confirms native CPU PM is not working

Native iMac19,1/9900K IPG on your workload would be enlightening

Hi toleda,
I checked, I have a reasonable spread in clock speeds, but it looks like hyperthreading isn't used in Logic with this song?!
Is this because of anti-meldown/spectre measures in Mojave?
Have a look at my screenshot. Any insights welcome!
