Assessment of Undervolting
It is quite astonishing how much the gain by the undervoltings for the two cards fails. The Radeon RX Vega 64 and Vega 56 benefit greatly in terms of performance and savings in power requirements. It can be clearly seen that the Radeon RX Vega 64 is already quite close to the limit and there is little potential. In the Radeon RX Vega 56, on the other hand, we see a large scope, which should also be used by anyone who loves the building.
The results for the Radeon RX Vega 64 are as follows: In terms of performance, the GeForce GTX 1080 Founders Edition is quite clear. We have no values for an undervolting of the competition cards here, but take these values only as reference points. It would be unfair to compare a low-voltage card with one in the delivery state. At the same time, the undervolting of the Radeon RX Vega 64 means a significant reduction in power consumption, even if it is still part of the current single-GPU cards.
The Radeon RX Vega 56 is a little better. Here we see a significant reduction in the power requirement, which makes the GeForce GTX 1070 (again without undervolting) closer. The biggest jump, however, is at the same time as the performance, because despite a reduction in the voltage, we were able to significantly increase the cycle, or hold more stable at a high level. In the benchmarks, therefore, she moves the larger Radeon RX Vega 64 quite close to the Pelle and can also leave the GeForce GTX 1080 behind.
Currently, however, an undervolting is still quite complicated, since the software can not be trusted. Indicators for the clock do not have to be correct and if the voltage has been accepted, is only ensured by a glance at the consumption. A simple setting of the values in the software is not enough at the moment - everything has to be validated.
