So, here is the thing. I have slim case with i7 9700k, so I can't install massive CPU cooler, so I decided to OC default 3.6 GHZ to stable 4.5 Ghz on all Cores. I have setup this all in Bios, and temps are ok. At the same time I'm comparing results with the Intel Turbo-Boost, that gives much more heat, and even throttling.
So, in general I finished with 2 profiles in Bios, one for Turbo-Boost and one for 4.5Ghz on all Cores with manual voltage setting and other stuff.
First I checked everything in Windows, and apart from general stability tests (like OCCT, IntelBurnTest, or Aida) and I have some results in:
Windows 10 Cinebench (4.5 Ghz all Cores)
3630 pts
Windows 10 Geekbench 5 (4.5 Ghz all Cores)
1294 Single-Core, 7909 Multi-Core
Also results for Turbo-Boost mode with full power control by motherboard. I won't use this setup cause it's too hot (it actually reaches 100C and throttles to smth like 4.6-4.7 Ghz), but it's nice to note results:
Windows 10 Cinebench (Turbo-Boost)
3810 pts
Windows 10 Geekbench 5 (Turbo-Boost)
1354 Single-Core, 8300 Multi-Core
After I concluded for myself it's fine by me, I switched to setup Mac OS using this tutorial - https://www.tonymacx86.com/threads/...g-i7-8700k-sapphire-rx580-pulse-build.272572/. After setup kext for sensors, I realised that it seems that Mac OS is slower. And also, it actually feels like it's slower a bit.
First of all, while in Windows with stable 4.5 on all Cores its Task Manager shows that it's really stable 4.5 Ghz, instead in Mac OS it jumps from 1.3 Ghz to 4.5 Ghz. So it seems like the OC ratio set in Bios is just a max limit, and not a static value.
Then I made tests and here are results:
Mac OS 10.15.2 Cinebench (4.5 Ghz all Cores)
3590 pts
Mac OS 10.15.2 Geekbench 5 (4.5 Ghz all Cores)
1156 Single-Core, 7804 Multi-Core
Mac OS 10.15.2 Cinebench (Turbo-Boost)
3701 pts
Mac OS 10.15.2 Geekbench 5 (Turbo-Boost)
1203 Single-Core, 8138 Multi-Core
Also, it's strange but in Cinebench in Mac OS it says that I have 4 Cores and 8 Threads (just in case - i7 9700k has 8 Cores, 8 Threads).
For me it looks weird. I understand that Windows and Mac OS are different platforms, so software can give different results. But how can I make sure that my OC is actually working on the same level as in Windows? I think that the reason of such difference with results may be the point that the frequency is not really stable in Mac OS. Probably it would give better results if my frequency is always 4.5 Ghz.
P.S.: I'm newbie to OC in Mac OS and to OC in general, so please forgive me any stupid questions and comments in advance
