First of all I would like to say thanks to you for sharing the experience and your EFI folder. I did install 10.14.5 to my PC successfully.
I have the same cpu and use the same ssdt but the turbo speed of my cpu is 3.3Ghz maximum. I also checked the CPU with intel power gadget and my turbo speed with 1 cpu core never passes 3.3Ghz, it should have been 3.6GHz with 1 core if I have not been wrong.
My Geekbench score is 10-20% lower than yours both single and multi cores
