Here you go.

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

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!

According to the thread you linked it appears that PM on 9900K isn't an option yet. Going off of this statement:

1. Coffee Lake/UHD630+ (Core i3/5/i7 9xxx, 9th Generation: TBA when native macOS support)

Also I learned from @pastrychef that other than PluginType=check nothing else is necessary in terms of PM.

I just tested something similar in Cubase Pro 10.0.20, I made my own project with 1 VI, 8 bass amps, 1 eq, 1 compressor, 1 reverb per track. I can do 56 tracks. Graphics updates are really slow, but no errors. 44.1 @ 128, MH ULN-8 via firewire.
That's a whopping 56 VI's with 600 or so plug ins... Much better load spread than in the Logic project, better CPU utilization, hypertreading works well, nearly 700% CPU load etc. In this case of apples against oranges. I will test this song rebooted in Win 10 when I have the time.

Look at that mixer... Haha!

Not a valid conclusion, IPG shows no non Turbo freqs

No.

Hyperthreading is not working, 16 "processors" should show
Activity Monitor show 4 of the 8 physical cores are doing all the work, remaining 4 physical cores have no work

I'm hammering the CPU, so it goes full tilt for the time IPG was recording. When doing other stuff, I see more speeds.

No.

Uh. I have a quad core/8 thread 6700K

Apparently, 4 out of 8 real/virtual cores do all the work in this Logic Project.

But in the Cubase example(second screen shot) all cores are fairly evenly loaded, total CPU load is nearly 700%, it looks like everything works as it should. Ass kicking performance, in fact.
These are all Steinberg's own VST plug ins, BTW. But the Logic project is also set up with just the basic Logic CoreAudio stuff(to make comparison easy, I guess)

So what goes 'wrong' with the Logic project? Or is this a weird corner case?

In daily use, Logic Pro and Cubase have about the same performance, Logic is a bit better with heavy VI's and a tiny buffer.
