AMD’s Radeon RX 9070 graphics card has proven to be a formidable competitor in the GPU market, especially when undervolted. Recent tests by renowned overclockers have shown that the RX 9070 can retain up to 90% of its performance while significantly reducing power consumption. One user shared their experience with an ASRock Radeon RX 9070 Steel Legend graphics card.

By undervolting the card by 100mV, they found that it delivered competitive performance while consuming 30% less power.

The GPU voltage dropped from the default 850-900mV to around 770-780mV, and the GPU clocks decreased to less than 2.2 GHz. Further undervolting by 50mV increased the GPU clock by around 100 MHz, with the voltage stabilizing around 740-750mV.

Additional undervolting pushed the GPU clock beyond 2.4 GHz. The user noted that undervolting between 50-100mV is stable, but going beyond that may cause crashes.

Retesting the GPU under these conditions showed that it delivered 50 FPS, 10% lower than stock settings but with a 30% better FPS per watt ratio.

This makes the RX 9070 a strong competitor against the RTX 4070 Ti Super, which only delivered 46 FPS in comparison. Even at reduced power consumption, the RX 9070 series remains impressive. At just 170W, the RX 9070 showed minimal difference compared to its default 200-220W consumption.

With an additional 10% power, the GPU clocks reached over 2.7 GHz and exceeded 2.8 GHz when undervolted, delivering up to 60 FPS—a solid 11% improvement over default settings. The RX 9070 XT has also demonstrated its potential when undervolted.

Multiple online tests have shown that the RX 9070 XT can outperform Nvidia’s RTX 5080 in real-world performance when undervolted. YouTubers Der8auer and Alva Jonathan performed rigorous testing on different models of the RX 9070 XT. Der8auer used the PowerColor RX 9070 XT Red Devil and found the best results by increasing the GPU’s power target to 110% and applying a -170mV voltage offset. This allowed the RX 9070 XT to achieve clock speeds of 3.36 GHz and resulted in a 10% FPS boost.

 

 

Undervolted benchmarks challenge NVIDIA supremacy

Alva Jonathan tested the ASRock RX 9070 Steel Legend and managed similar results by undervolting and tweaking the power draw, gaining a 10% FPS improvement. Despite the cost markups, these factory-overclocked cards exhibit impressive performance when undervolted. Initially sold for $799, the PowerColor Red Devil remains $200 cheaper than the RTX 5080.

With undervolting and proper tweaking, the RX 9070 XT can surpass the RTX 5080 in certain games like Cyberpunk 2077. The RX 9070, utilizing AMD’s RDNA 4 architecture, features 56 compute units and 16GB of GDDR6 memory. The 9070 XT, which performs roughly 9-12% better than the 9070 in most games tested, also uses 16GB of GDDR6 memory but with 64 compute units.

The RX 9070 stands out as one of the most efficient GPUs on the market. Its MSRP is $550, whereas the 9070 XT is $600. In various game benchmarks, the RX 9070 demonstrates significant efficiency and impressive performance relative to its price point. It offers a strong alternative to NVIDIA’s RTX 5070 series, particularly in several key titles tested.
