Buildzoid’s latest video tackles the subject of P-State overclocking with AMD’s latest Ryzen platform processors. It’s a topic that seems to divide opinion in certain segments of the hardcore overclocking community. The idea is that AMD Ryzen processors use power performance states, also known simply as P-States which involve different frequencies and voltages for different load conditions. This allows the system to dynamically alter voltages each core when you don’t need the power, and boost voltages when clocks when the system is under full load. That’s pretty much the theory anyway. According to Buildzoid, the reality may be somewhat different.
To quote Buildzoid himself. People want to know more about power savings. “Ok…here’s your freaking power savings!” He presents power draw data from a system based around an AMD Ryzen 7 1700 processor using an ASRock X370 Taichi motherboard. The power is measured at the wall in an attempt to genuinely see if a P-State configuration in BIOS actually effects what the system is pulling at various loads and frequencies. The outcome is, to again quote the man himself, that “P-State overclocking is pointless and a waste of time.”
