Undervolting – performance/power consumption/fan noise
Undervolting – performance/power consumption/fan noise
Here are the results of the undervolting, showing the performance figures. The temperatures/fan rpm data you'll find below the charts.
Below you can find the following effects of the undervolting:
- Frequency (including the effective one)
- GPU/memory/hotspot temperatures
- Fan RPM/noise
- Maximum power consumption
- Performance in 5 games
| Label | default | 1050 mV | 1000 mV | 950 mV |
| Frequency | 2610 MHz | 2650 MHz | 2580 MHz | 2500 MHz |
| Effective frequency | 2620 MHz | 2750 MHz | 2635 MHz | 2520 MHz |
| GPU temperature | 69.2 ℃ | 68.5 ℃ | 65.8 ℃ | 61.1 ℃ |
| Memory Temperature | 62.0 ℃ | 60.0 ℃ | 59.0 ℃ | 58.0 ℃ |
| Hot Spot temperature | 79.4 ℃ | 78.8 ℃ | 72.9 ℃ | 70.5 ℃ |
| Fan RPM | 1500 rpm | 1450 rpm | 1350 rpm | 1300 rpm |
| Fan noise | 39 dBA | 38.5 dBA | 37.5 dBA | 37 dBA |
| Max Power Consumption | 280 W | 260 W | 235 W | 215 W |
| Avg Power Consumption (games) | 250W | 240W | 215W | 200W |
| CyberPunk 2077 (FHD) | 124 | 127 | 125 | 122 |
| F1 2022 (FHD) | 302 | 307 | 303 | 298 |
| FarCry 6 (FHD) | 169 | 173 | 170 | 166 |
| Hitman 3 (FHD) | 186 | 190 | 188 | 183 |
| Shadow of the Tomb Raider (FHD) | 235 | 241 | 236 | 231 |
| Average performance | 100,00% | 102,23% | 100,65% | 98,39% |
| Efficiency (Power Consumption vs Performance) | 100,00% | 106,49% | 117,03% | 122,99% |
At the bottom, you can see the average performance (relative) vs the default setting.
Last but not least - the efficiency, so you can see that lowering the voltage to 0.95 V made the biggest impact. You lose not so much in the performance, but the power consumption dropped by 65 W (almost 25% of the default figure), when having a full load, and 50 W in the average for games (so it dropped by 20%).
