Intel CPUs only
CPU naming is fairly easy to figure out as well, open your decompiled DSDT and search for Processor. This should give you a result like this:
As we can see, the first processor in our list is PR00. This is what we'll be applying the plugin-type=1 property too. Now grab SSDT-PLUG and replace the default CPU0 with our PR00. Note that there are 2 mentions of CPU0 in the SSDT.
There are also some edge cases with Processor, specifically on HEDT series like X79, X99 and X299. This edge case is that the ACPI path is much longer and not so obvious:
If we then search for instances of CP00 we find that it's ACPI path is SB.SCK0.CP00:
So for this X299 board, we'd change \_PR.CPU0 with \_SB.SCK0.CP00 and External (_PR_.CPU0, ProcessorObj) with External (_SB_.SCK0.CP00, ProcessorObj)
