GPU power consumption and efficiency in Full HD (1920 x 1080 pixels)
The GPU, since the CPU load is a bit higher here, is just under 160 watts, which isn’t surprising since Dynamic Boost doesn’t always allow the maximum 165 watts. It bounces back and forth like a nervous ibex. But you’re even well below the much weaker RTX 3060 as a desktop card. Not bad.
This is of course reflected in the efficiency, where you can win the comparison of all cards really hands down. Big chip with little clock is pure sweet spot feeling. But that’s nothing new.
GPU power consumption and efficiency in WQHD (2560 x 1440 pixels)
In WQHD, the CPU load drops significantly and the GPU is allowed to draw almost the 165 watts of the power limit including the 15 watts addition from Dynamik Boost. But even then, it is still below the much weaker RTX 3060. So the sweet spot applies even more here.
The efficiency score has remained very similar to the other cards, making the RTX 3080 Laptop once again the winner at the wall socket. So you can see very well what reserves are in these big chips if you don’t push them to the limit. Because then they can also be economical.
Interim summary
The GeForce RTX 3080 Laptop is the benchmark par excellence in terms of efficiency, and none of the desktop cards we also tested can even come close.
