AMD Ryzen 7 5800X3D is significantly more efficient thanks to 1V lower voltage

Despite the AMD Ryzen 7 5800X3D’s built-in limitations, overclockers were able to push the chip’s frequency beyond 5GHz using an increased bclk. Meanwhile, the new Ryzen flagship is indeed available and a Wccftech reader has started working on low voltage to make the processor more efficient.

For example, Shaun was able to reduce the voltage of the octachord to 1 volt, so there was no loss of performance, he says. Thanks to the low voltage, the CPU does not heat up more than 43 °C in Cinebench compared to 80 °C at standard settings. All cores are boosted to 4.4 GHz, while power consumption is only 73 W.

The 5800X3D was tested with a custom loop with 420mm radiator and Asus Prime X570-Pro motherboard.

Eventually, Shaun reached a voltage of 0.844 V, the lowest voltage at which the chip is stable. Power consumption and temperature decrease again in Cinebench (57 W and 41 °C), but the 3DMark FireStrike test shows performance drops as well: Physics score drops by about 15%.

Other than FireStrike, no gaming benchmarks have been done to test low voltage gaming performance. In any case, this is an indication of the potential efficiency of the Ryzen 7 5800X3D.
