How to Undervolt AMD Radeon GPUs: Lower Temps by 15°C Without Losing Performance
In 2025, undervolting an AMD Radeon GPU remains one of the most effective ways to boost efficiency, cut down on heat, and even gain performance stability — all without spending a dime. Whether you’re tuning an RX 6000, RX 7000, or the new RX 9000 series, the process is simpler than you might think, thanks to AMD’s built-in Adrenalin software suite. What Is GPU Undervolting? Undervolting means reducing the voltage supplied to your GPU cores while keeping the same frequency or clock speed. Instead of limiting performance like underclocking, undervolting intelligently lowers power draw and heat output, helping your GPU sustain higher boost clocks under load. At a technical level, this works because GPU power scales by the formula: P ∝ V 2 × f P \propto V^2 \times f P ∝ V 2 × f where P P P = power, V V V = voltage, and f f f = frequency. Even a small drop in voltage can reduce heat output exponentially since power changes with the square of voltage. Undervolting typically reduces temperatures by 10–15°C and c…
