Video blogger and overclocker der8auer checked how the new Radeon RX 9070 XT graphics card in the Red Devil version from PowerColor performs when overclocked manually. Using an experimental method, he found that there is practically no difference with the traditional overclocking method. However, when undervolting, he managed to achieve performance higher than that of the GeForce RTX 5080 in stock condition. The PowerColor Radeon RX 9070 XT Red Devil supports dual vBIOS with quiet and performance modes. But during the tests, there was no significant difference in performance and heating: the GPU  GPU-accelerated computing is the use of a graphics processing unit (GPU) together with a CPU to accelerate deep learning, analytics, and engineering applications. heats up to 62-63 degrees, and the temperature of the hottest spot reaches 85 degrees.The overclocker increased the upper power limit to 110%, which was about 360 W in GPU-Z. In this mode, the video card overclocked to a frequency of over 3.1 GHz. Then he began undervolting, reducing the operating voltage of the graphics chip by 200 mV. Thanks to this, the 3DMark Time Spy test recorded an overclocking of up to 3.4 GHz - 300 MHz higher than the value declared by the manufacturer. However, the video card refused to work stably in this mode and could not even complete the test. Having tried several options, the blogger found the optimal undervolting value - 170 mV. After tuning the PowerColor Radeon RX 9070 XT, the Red Devil was able to slightly outperform NVIDIA's new reference design GeForce RTX 5080 in 3DMark Time Spy Xtreme. The Cyberpunk 2077 test also showed a slight advantage for the modified RX 9070 XT over the RTX 5080 and even the RX 7900 XTX. As a result of successful undervolting, the PowerColor Radeon RX 9070 XT Red Devil turned out to be faster than the GeForce RTX 5080 FE in Cyberpunk 2077 and the synthetic 3DMark benchmark. Of course, this victory is not a sure thing, since the RTX 5080 can also be overclocked and get an additional 10% of performance. But still, we are talking about comparing a video card for $700-800 with a card costing $1000-1200. |
