You're a wizard!

Perhaps faking CPUs is a step too far as macOS can’t schedule threads on CPUs that don’t exist ?

Perhaps just leave the CPUs as discovered from the madt and patch macOS to successfully bypass x86_validate_topology() ?

It seems macOS tries to activate each core/thread and times out if an “ack”nowledgement is not received. So faking a CPU by logically connecting it to a real thread (@Elias64Fr new CPUR and APIC) was intended to avoid this activation problem. That was the hope anyway!

Can we assign HT to each core specifically ?
what is the order of the cores? 0-5 P, 5-9 E? I wonder if macOS can run stable with the thread count NOT being x2 times the core count.

I don't think that it's possible on BIOS.
Yes, E-Cores are assigned after P-Cores.
That's a big question ! We came, we tried and we saw ;)

I know, I have those crazy background (low power) threads running in my brain at bedtime as well! :)


Case 1: E + P + HT
  • smbiosview in EFI Shell actually freezes when running this command, but we get enough information on screen by typing smbiosview -t 4 to show only the processor information.
  • We see:
    • Core Count = 10
    • Thread Count = 16

You missed related SMBIOS view ? I mean for Case 2 and 3...

You can install dmidecode on macOS with : brew install dmidecode ... (like flashrom) OR
you have an alternative way from Acidanthera GitHub here, you can download binary file and call exec with ./dmidecode
This Acidanthera's version allow decoding following Apple's specification :)

I decided to order an i7-12700K rather than the i9-12900k
Since i'm building a Mini-ITX build, cooling is a challenge, especially in the Phanteks Shift 2 Glass edition.

Looking at benchmarks, I don't think I will feel any real life performance difference, also look at the power consumption below:

The 12900K is a room heater!

Have you seen this? Although I agree the i7-12700K is a better choice for Mini-ITX.

Interesting.
I'm a Frontend developer, compiling Webpack (Javascript bundler) can consume 100% cpu usage for 1min or more.
Other than that, I don't have any other real 100% cpu demanding tasks
I'm really not sure, I do have a budget for the i9-12900k but I wonder if an 120mm AIO is enough
 
If I use dmidecode -u command, on my laptop, I have :

Here, we have Core Count to 6, Core Enabled to 6 and Thread Count to 12

For Z690, we could try patching Core Count and Core Enabled to 8 (instead of current 10) and let Thread Count to 16
