A user on Reddit reported undervolting an NVIDIA RTX 5070 Ti graphics card to 0.67V, resulting in a 52 percent reduction in power draw. The configuration achieved a peak draw of 142.8W while maintaining a 1,890MHz clock speed.
Why it matters
Undervolting demonstrates how enthusiasts can drastically improve power efficiency beyond factory settings. This practice remains a primary method for reducing heat output and electrical load without compromising performance in high-end desktop hardware.
The RTX 5070 Ti reached a peak power draw of 142.8W, a 52 percent reduction against its 300W TGP rating. The GPU maintained a 1,890MHz clock speed and 17,501MHz memory speed at 0.67V.
The players
NVIDIA
A designer of graphics processing units that maintains the GeForce brand of desktop hardware.
The details
The user achieved these results by applying a core voltage offset of -145mV and a core clock offset of +300MHz via mVolt+ Extreme v0.47.2 software. This adjustment forces the GPU to operate at a lower voltage curve while sustaining high clock frequencies, keeping hotspot temperatures at 51.8°C. The system utilized a PCIe 4.0 x16 link and a Ryzen 7 5800XT processor during the tests conducted with driver version 621.01.

The Tech Race
This effort follows a trend of hardware enthusiasts pushing the efficiency limits of modern GPUs beyond manufacturer baselines. By bypassing the 300W TGP rating, the modification highlights the gap between out-of-the-box power settings and the physical limits of current silicon architecture.
Users with compatible high-end desktop hardware may be able to significantly lower thermal output and electricity usage through similar voltage offsets. The process requires third-party software and carries potential risks to system stability if configured incorrectly.
The takeaway
Undervolting remains an effective way to optimize GPU performance per watt for advanced desktop users. Watch for future community benchmarks using mVolt+ Extreme v0.47.2 to see if similar efficiency gains hold across different silicon batches of the RTX 5070 Ti.
