A AMD Radeon RX 9070 demonstrated energy efficiency without significant loss of performance when undergoing a process of undervolt. Recent tests indicate that even reducing the voltage in 100mVthe GPU maintains 90% of original performancewhile energy consumption decreases up to 30%.
O overclocker Alva Jonathan performed tests at ASRock Radeon RX 9070 Steel Legendadjusting the voltage of the GPU of 850-900mV para 770-780mV. With this modification, the plate recorded a reduction in the frequency of clock to less than 2,2 GHzbut still kept 50 FPS No benchmark of Cyberpunk 2077 em 4K Ultraa result close to 54 fps obtained with the original configuration.
When applying a Additional 50mV undervoltGPU clock increased to 2,4 GHzimproving efficiency. However, adjustments higher than 100mV resulted in instability, limiting the safe margin of modification.
Comparative tests revealed that the RX 9070 com undervolt overcame RTX 4070 Ti Superwhich marked 46 FPSwhile maintaining proximity to the version RX 9070 XTthat obtained 63 FPS.
In addition, the plate consumed only 170Wcompared to 200-220W of the default configurationwhich shows the improvement in the relationship between performance and energy consumption.
FPS Comparison in Cyberpunk 2077
A benchmarks chart presented in the video demonstrated how different settings of the RX 9070 behave in Cyberpunk 2077 running in DX12, 4K Ultra, sem upscaling:
- Radeon RX 9070 XT 16GB (ASRock Taihichi) – 63 FPS
- Radeon RX 9070 16GB (ASRock Steel Legend) – OC 3GHz – 60 FPS
- GeForce RTX 5070 Ti 16GB – 58 FPS
- Radeon RX 9070 16GB (Asrock Steel Legend) – Standard – 54 FPS
- Radeon RX 9070 16GB (ASRock Steel Legend) – Undervolt 2,4 GHz – 50 FPS
- GeForce RTX 4070 Ti Super 16GB – 46 FPS
The numbers indicate that the undervolt can be an alternative for users who want reduce energy consumption without significantly compromising performance.
Another test explored a scenario in which, by reducing the voltage in Additional 50mva RX 9070 reached 2,95 GHzan increase of 250 MHz above Boost Clock Official.
In this scenario, the plate got 60 FPS em Cyberpunk 2077representing a gain of 11% in relation to the default configuration.
