Quote from: Pioter888 on May 19, 2024, 13:42:52Hi, can someone explain why power consumption in one test stabilized at ~45W and in another at 78W? Why are they throttled at different levels?
If I understand it correctly the 45W is where the CPU stabilizes. The spec sheet at the beginning of the article shows that the CPU is configured with a PL1 of 45W, which is the value it will stabilize under sustained load. Higher wattage (PL2 of 90W) can only be used for short load spikes.
Also those 45W apply to the CPU only, without any other components (like mainboard, RAM, SSD, cooler).
Then later in the section "Power Management", they measured 78W which probably applies to the whole device (all components together: CPU, mainboard, RAM, SSD, cooler) under sustained load. Whereas 45W from the 78W are already used by the CPU, and the remaining 32W are used by the other components.
At least that's what I think it is...
