AMD Radeon RX 9070 – Undervolting Reduces Power Consumption by 30% Without Losing Performance

Graphics card AMD Radeon RX 9070 showed impressive results in undervolting, keeping high performance with significant reduction in energy consumption. Overclocker Alva Jonathan tested ASRock RX 9070 Steel Legend and found out that voltage decrease by 100 mV reduces power consumption on 30%, but FPS decreases all in 4 frames.

In the test Cyberpunk 2077 with standard settings the card gives out 54 FPS, and then undervolting - 50 FPS, what is 10% differencebut at the same time FPS per Watt increases by 30%.

During the tests, the voltage GPU было reduced from 850-900 mV to 770-780 mV, which made it possible to achieve clock frequency 2.4 GHz. In the future reducing tension to 740-750 mV frequency increased up to 2.7 GHz, and with additional decrease by 50 mV - up to 2.95 GHz.

Reduction energy consumption с 200-220W up to 170W makes RX 9070 more an effective alternative RTX 4070 Ti Super, which scored in the same test 46 FPS with higher energy consumption. Overclocking RX 9070 allgo by 10% increased frequency up to 2.8 GHz, and the FPS went up to 60, What's on 11% above standard values.
