Single monitor idle power consumption has been greatly improved over previous Vega cards. With only 8 watts in idle, it's now right where it should be.
Unfortunately, multi-monitor power consumption is still bad, nearly three times that of competing NVIDIA cards.
Media playback power draw is good—lower than on any other AMD card and better than NVIDIA's RTX lineup.
Gaming power draw is surprisingly low with just 166 W and matches the 164 W of the RTX 2060 almost exactly, yet the RX 5700 is faster at the same time. Now, you should be screaming "Whaaaat?! Does that mean the RX 5700 is more power efficient than RTX 2060?" Yes, that's true. AMD has achieved the unimaginable and managed to make their card 3%–5% more power efficient than the RTX 2060. How did they achieve this? The trick is basically to undervolt the card a lot. More on that on our Clock Speeds & Power Limit page (page 32).
