Abstract:
NVIDIA's DLSS5 technology has now been officially launched with NBA2K27. It currently mainly supports RTX 50 series graphics cards, and the number of games also needs to be expanded. This is a problem that needs to be solved in the future. Since its release at the beginning of the year, DLSS5 has been very controversial. Some are worried about the distortion of the picture quality, and some are worried that game developers will be lazy because of it. There has been a lot of discussion in this regard. In the past two days, a large number of domestic and foreign reviews have been released. You can refer to the first review of this site - the first game to support DLSS 5! "NBA 2K27" first hardware test.
In addition to the performance and image quality issues that everyone is concerned about, there is another issue that needs to be mentioned, that is, DLSS5 technology will also increase the power consumption of the graphics card. The evaluation on the German Computerbase website has detailed results, as shown below:
They compared the power consumption of multiple graphics cards ranging from RTX 5060 to RTX 5090 with DLSS5 turned on and off at 2K and 4K resolutions, and the results are clear at a glance.
Let me talk about the conclusion first. DLSS5 will increase the power consumption of the graphics card. After all, the load of DLSS5 is not low. It is equivalent to the graphics card running an additional local large model. As the load increases, theoretically the power consumption will naturally increase.
But the specific increase in power consumption depends on the graphics card. The increase in power consumption of the RTX 5060 graphics card is almost negligible. The RTX 5060 Ti and RTX 5070 increase the power consumption by about 10%, but the absolute value is still acceptable.
The power consumption gap between RTX 5070 Ti is more obvious at 2K, and the gap shrinks to about 10% at 4K.
However, the two high-end graphics cards RTX 5080 and RTX 5090 have a very obvious increase in power consumption. The increase is about 60%. The increase is significantly reduced at 4K. The RTX 5090 has an increase in power consumption by 40%, and the RTX 5080 has an increase in power consumption by about 25%.
Taken together, DLSS5 has a more obvious increase in power consumption for graphics cards with stronger performance, and the increase is greater at 2K than at 4K.
As for the reason for the surge in power consumption, the original text did not explain it. Logically speaking, DLSS5 should be using the tensor core of the graphics card. Previous DLSS did not significantly increase power consumption, but their requirements for super-resolution and light-tracing reconstruction were also lower than DLSS5.
