Uglavnom, zaključak je ono kaj je bilo rečeno i u inicijalnim recenzijama. Automatika je jako sposobna, ali opet - ne treba ju baš pustiti da radi kaj ju volja.

For AMD’s new Ryzen 5000 processors, most of them have a 105 W TDP, with a Package Power Tracking (PPT) setting of 142 W. For these processors, we can see our peak power consumption through our testing matching that value. For the sole 65 W processor, the PPT value is 88 W, and we’re seeing only 76 W, showing some of the efficiencies on the Ryzen 5 5600X. Most of this test sits around the 130 W mark, as the workload has a variable thread count. There are a couple of momentary spikes above 140 W, however everything is well within expected parameters. Due to AMD’s PPT implementation, we’re getting very consistent peak power results between multiple generations of AMD processors.

The new Ryzen 5000 "Zen 3" processors are even more independent from the OS than before for power management. The CPUs mostly rely on themselves in gauging processing load and responding with the appropriate performance budget. The "Zen 3" CPU core can operate at voltages ranging all the way from 0.2 V to 1.5 V (normal operation). The same Precision Boost 2 algorithm is used as on "Zen 2" Ryzen 3000 series processors. CPU clock speed boost, voltage adjustments, and clock-gated sleep changes occur at a 1 ms timescale, compared to the 15 ms tick-rate for OS-dictated power management. AMD has also enabled 0 V (power-gated) sleep, with the CPU cores able to jump to power-gated sleep states without being "disturbed" by monitoring tools. Changes have been made to minimize the "observer effect" on CPU cores by monitoring tools.
