6. Power consumption, temperatures, noise
Below you see the peak power consumption we measured during some of our benchmarks.
Peak Power consumption (Watt)
|GeForce RTX 2080 Ti (11GB)||GeForce RTX 2080 (8GB)||GeForce GTX 1080 Ti (11GB)||GeForce GTX 1080 (8GB)||Radeon RX Vega 64 (8GB)|
|3DMark Time Spy||358||304||328||248||368|
|3DMark Time Spy Extreme||334||281||304||224||347|
|3DMark Fire Strike||375||324||347||250||382|
|3DMark Fire Strike Ultra||333||286||307||224||347|
|VRMark Orange Room||347||304||338||295||422|
|VRMark Cyan Room||395||334||346||258||361|
|VRMark Blue Room||364||307||324||241||387|
As you can see, the idle power consumption of the GeForce RTX 20 series is slightly higher than the 40W and definitely higher than the competition. According to Nvidia, a driver update will address this issue shortly and bring idle consumption down.
On average, the GeForce RTX 2080 consumed 10-20W less that the GeForce GTX 1080 Ti, and up to 80W more than the GeForce GTX 1080. Considering the performance gains of the GeForce RTX 2080, we could say that it is more power efficeint than the GeForce GTX 1080 Ti.
The power consumption of the GeForce RTX 2080 Ti maxed out at 420W and was overall 15 - 50W higher than consumption of the GeForce GTX 1080 Ti. But you should have in mind that this value also includes the power consumption of the CPU. In any case, if you want to use the GeForce RTX 2080 Ti you should consider buying a power supply unit that will cover both the CPU and GPU power requirements.
In terms of temperatures, NVIDIA has made a great job with the new GeForce RTX series. The RTX 2080 Ti runs at a maximum of 75C during most testing with its fans on auto and only 60C maximum with the fans are spinning at 100%. This is a great improvement compared to the Pascal GPUs.
The great cooling configuration of the new cards keep the temperatures relatively low, meaning that the fans are also not spinning at 100% unless you push things too much.. In any case, the RTX 2080 is quieter and cooler than the GTX 10 Founders Edition cards (GTX 1080/1080 Ti/TITAN Xp).
