In real work scenarios, the power consumption of the GeForce RTX 4080 graphics card was lower than specified in the specifications. This is reported by NVIDIA, as well as data from independent tests of the graphics card in games and various synthetic benchmarks.
A comparison of the GeForce RTX 4080 with previous generation NVIDIA graphics cards showed that the new product is significantly more energy efficient due to the new Ada Lovelace architecture, according to NVIDIA. For example, with the same maximum power consumption (Total Graphics Power, TGP) of 320 W in real work scenarios, the consumption of the GeForce RTX 4080 was significantly lower than that of the predecessor GeForce RTX 3080.
Under typical workloads, the power consumption of the GeForce RTX 3080 corresponds to the declared 320 watts. For the GeForce RTX 4080, on the other hand, it averages 251W, or 78% of the advertised value, says NVIDIA. It is also worth noting that the GeForce RTX 4080 is significantly more productive and energy efficient than the flagship GeForce RTX 3090 Ti, which draws an average power consumption in games of 389 watts with a declared maximum value of 450 watts.
The GeForce RTX 4080 obtained its findings about the high energy efficiency based on 22 gaming tests with 4K, 1440p and 1080p resolutions as well as testing the graphics card in video playback mode with the AV1 codec.
In the Control, Cyberpunk 2077, Forza Horizon 5, and Guardians of the Galaxy Metro Exodus gaming tests, the GeForce RTX 4080 accelerator consumed no more than 300 watts when using 4K resolution, ray tracing, and DLSS scaling. The lowest consumption is observed with Full HD resolution. Independent tests of the new graphics card show similar results.
