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 (1150 mV) | 1100 mV | 1050 mV | 1000 mV |
| Frequency | 2600 MHz | 2680 MHz | 2660 MHz | 2625 MHz |
| Effective frequency | 2610 MHz | 2700 MHz | 2675 MHz | 2640 MHz |
| GPU temperature | 63.3 | 59.5 | 58.2 | 56.4 |
| Memory Temperature | 65.9 | 63.2 | 61.5 | 60.2 |
| Hot Spot temperature | 75.7 | 71.9 | 66.7 | 64.3 |
| Fan RPM | 1400 rpm | 1360 rpm | 1280 rpm | 1220 rpm |
| Fan noise | 37.1 dBA | 36.7 dBA | 35.9 dBA | 35,5 dBA |
| Max Power Consumption | 250 W | 235 W | 220 W | 205 W |
| Avg Power Consumption (games) | 220 W | 205 W | 200 W | 185 W |
| CyberPunk 2077 (FHD) | 112 | 116 | 115 | 113 |
| F1 2022 (FHD) | 284 | 291 | 288 | 286 |
| FarCry 6 (FHD) | 162 | 168 | 166 | 164 |
| Hitman 3 (FHD) | 192 | 197 | 196 | 194 |
| Shadow of the Tomb Raider (FHD) | 216 | 225 | 221 | 218 |
| Average performance | 100,00% | 103,3% | 102,19% | 100,96% |
| Efficiency (Power Consumption vs Performance) | 100,00% | 110,86% | 112,41% | 120,06% |
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 1.00 V made the biggest impact. You do not lose the performance, but the power consumption dropped by 45 W (almost 25% of the default figure) when having a full load, and 35 W on average for games (so it dropped by around 15% without sacrificing the results).
