Using CPU reservation is not a common thing, I mean if you reserver a certain amount of CPU compute it can have it's cons.
Anyway, a thing you can do is (and probably the only one) is to multiply the speed of a singe core to the amount of times you want to "reserve".
That would be an approximation because it's not always the exact amount.
If you take 2300 MHz x 16 = 36800 MHz, that would be the amount of CPU compute to reserve.
You could find more information here: Calculating Maximum CPU Reservation For a VM With 6 CPU
Hope this helps.
