Recent testing has shown that DLSS 5, the latest version of NVIDIA's neural rendering technology, significantly increases the power consumption of its new RTX 50 series graphics cards. In the game Cyberpunk 2077, the GeForce RTX 5090 Founders Edition sees its power draw rise from 482 watts to 551 watts when DLSS 5 is enabled. Similarly, the MSI RTX 5090 Lightning Z model experiences a larger jump, going from 580 watts to 723 watts in the same game. This represents a substantial increase, especially when compared to the standard Founders Edition model, which has a 575-watt power limit. In another game, Hogwarts Legacy, the Lightning Z model's power consumption increases from 480 watts to 720 watts, which is a 50% jump. In Control, the same model's power usage rises from 691 watts to 802 watts when DLSS 5 is active. These tests were conducted using a leaked version of DLSS 5 implemented by the community through a tool called OptiScaler, before the official release of the technology. This suggests that the performance benefits of DLSS 5 may come at a higher cost in terms of power consumption. Other models in the RTX 50 series also experience notable increases. The RTX 5080 sees its power consumption rise by about 100 watts when DLSS 5 is enabled, reaching its 360-watt power limit. The RTX 5070's power draw increases from 147 watts to 250 watts in quality mode, while the RTX 5070 Ti's power consumption rises from 192 watts to 300 watts. Meanwhile, the RTX 5080’s power use goes from 291 watts to 349 watts, and the RTX 5090’s power draw increases from 374 watts to 575 watts. These findings highlight that DLSS 5, while offering performance improvements, can significantly increase the power consumption of various RTX 50 series models. This may have implications for users concerned about energy use, cooling requirements, and power supply capabilities. As the technology is still in its early testing phase, more data may emerge as the official release of DLSS 5 approaches.
