Idle power consumption of RTX 3080 Ampere is a little bit better than Turing 2080/2080 Ti. While it's only a few watts, the 4 W savings are definitely appreciated, especially for people who work on their gaming PC all day.
Multi-monitor power consumption matches Turing almost exactly. The new media decode engine, while more powerful, also draws a bit more power. A 6 W increase over the 2080 Ti isn't a huge deal, but still surprising.
Gaming power consumption is at the top of our charts, but the performance on tap with the RTX 3080 is more than impressive. Around 300 W is only 10% more power draw than the RTX 2080 Ti—while achieving +25% gaming performance. When considering performance per watt, the improvement is "nice", but certainly not groundbreaking. I guess the next move to TSMC 7 nanometer or below could achieve that.
Furmark maximum power reaches 370 W, which is right at the limit of the card's 12-pin + PCIe slot power input capability.
Recommended PSU: 700 W
