The Frost Canyon devices major on energy conservation and low base clock speeds mean that their starting point is low before system demands ramp up clock speeds and available power. This may be what is slowing the system down. I haven’t played with one of these yet but one possible option is to go into bios and set the device into a higher performance mode if that is possible. These higher TDP models (compared to anything up to 7th gen) use lots of performance management to keep things cool and power consumption down.
