The famous overclocking player overclocked the PowerColor RX 7900XTX to 3.25GHz
We previously reported on a series of news about the PowerColor Radeon RX 7900 XTX Liquid Devil in February, with the design goal of providing players with ultimate performance. According to VideoCardz, the famous YouTube tech blogger Der8auer recently pushed the performance of this water-cooled graphics card to its limit.
First of all, let’s introduce the foundation of this card. It uses an EK custom cold head and is equipped with three 8-pin connectors and a 17-phase power supply, which can fully unleash the potential of the graphics card. However, Der8auer needed to do more on this basis. He used the EVC2SE module from ElmorLabs, a component for fine voltage control.
After selecting the overclocking BIOS, the frequency of this RX 7900 XTX has reached around 3.0GHz, with power consumption reaching up to 420W. After Der8auer used EVC2SE to increase the voltage to 1.050V, the frequency and power consumption of the graphics card were further increased to 3.05GHz and 500W, respectively.
The ultimate result of the overclocking is that the RX 7900 XTX passed the 3DMark Time Spy Extreme test at 3.25GHz. The frequency can reach up to 3.38GHz at lower loads, while power consumption reaches up to 650W and the temperature reaches 100 degrees. Compared to the reference RX 7900 XTX, the graphics card after extreme overclocking achieved a 28% performance improvement.

Unfortunately, even with the RX 7900 XTX pushed to such a limit, its score is still lower than Nvidia’s RTX 4090 Founder Edition by about 7.2%.
Through Der8auer’s experiment, combined with the previous news, it is easy to understand why AMD said they abandoned the development of a super flagship GPU that competes with the RTX 4090 after weighing cost and power consumption. Assuming that this AMD GPU does exist, the parameters of scale and power consumption should be astonishingly high.
