I've said it here before, don't use CPUFriend + CPUFriendDataProvider.kext provided here on iMacPro1,1 SMBIOS, it has injected frequency vectors from iMacPro1,1. You don't need to use the frequency vectors from iMacPro1,1 on iMacPro1,1 SMBIOS, it doesn't make any sense.

For Sidecar you need Intel iGPU or T2 chip... so on Alder Lake its no go.

Hello @CaseySJ, can you try this CPUFriendDataProvider.kext with iMac20,X frequency vectors, but with corrected QoS values?

@CaseySJ can you rerun benchmark with iMac20,2 SMBIOS without CPUFriend pls? I want to see if we could use vectors from iMac20,2 with Comet Lake CPU which is closer to Alder Lake than iMacPro with Intel Xeon W. EDIT: Or wait, I'll prepare a CPUFriendDataProvider.kext with vectors from iMac20,2...

If you switching SMBIOS, the results can vary, because every SMBIOS uses different frequency vectors, BUT if you switching SMBIOS and always overwrite frequency vectors with vectors, for example, from iMacPro1,1 you will have similar results.

It looks like @CaseySJ used "CPUFriendDataProvider.kext with iMacPro1,1 frequency vectors" in these test, so it should be same as on MacPro7,1 with same kext...

If you are using CPUFriend in tests with the kext I dropped here, you should mention, that it use iMacPro1,1, frequency vectors. Something like "CPUFriend enabled + CPUFriendDataProvider.kext with iMacPro1,1 frequency vectors".

So, if you are using iMacPro1,1, don't use CPUFriend + CPUFriendDataProvider.kext provided here, its created for MacPro7,1. Whats in "AVX Disable"? This is how enable AVX512 looks like on Asus BIOS.

Which SMBIOS are you using in the first test? "CPUFriendDataProvider.kext" i dropped here have injected frequency vectors from iMacPro1,1... so if you are using SMBIOS iMacPro1,1 it should have the same Geekbench result with and without this kext. Do you have enabled AVX512 in BIOS? If all E...

Yes, true, but all real world apps test that I see on Windows have better results with all P cores on/all E cores off and HT enabled than all P cores on/all E cores on and HT disabled. Edit: And there is another one problem for using E cores... you need OS scheduler to make decisions about...

Thanks. So until we figure out a way to get all the cores up (P+E) with HT, this is the best setup for now. Its 6 P-cores and HT for 12600K ;)

Nice :) Whats your Geekbench 5 with all P cores on, E cores off and hyperthreading on? It should be even better.

Where does verbose boot end?

Its from /System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/PlugIns/X86PlatformPlugin.kext where Apple has stored plist files with frequency vectors for all Macs. When you use iMacPro1,1 it will get frequency vectors from the corresponding plist file... Mac-7BA5B2D9E42DDD94.plist...

Hello, CPUFriend is definitely a better solution. No need to change MacPro7,1 SMBIOS, just inject frequency vectors from iMacPro1,1 to CPUFriendDataProvider.kext and use it together with CPUFriend.kext. Edit: I attach CPUFriendDataProvider.kext with iMacPro1,1 frequency vectors (Use it together...

Im using this app - HWMonitorSMC2 For showing GPU information you need to do this: go the preferences and enable "Use the IOKit monitoring for GPUs" and the app will start using the PerformancesStatistics, under the IOAccelerator class in the IO, to retrieve informations about graphics cards.

Hello, I have the opposite behavior. With iMacPro1,1 after boot i have 800MHz and when i play video on the You Tube it drops to 500MHz. After video was closed, it jumps back to 800MHz. It starts acting like that from Catalina 10.15.3. Weird.
