NVIDIA is planning to launch the next generation of GeForce graphics cards, codenamed “Blackwell”, which are expected to consume more power than the current RTX 40 series. According to the leaker Kopite7kimi, the upcoming series, which includes models such as the RTX 5090 and RTX 5080, will have higher thermal design power (TDPs) than their predecessors. This information is particularly relevant for users who also need to consider energy consumption when purchasing graphics cards.
The TDP is a measure of how much power a GPU needs to work effectively and provides information about the demands placed on the cooling system and power supply. According to the latest reports, the RTX 5090 will have a TDP of 600 watts, which corresponds to an increase of 33 percent compared to the RTX 4090, which is rated at 450 watts. The RTX 5080 could have a TDP of 400 watts, which represents an increase of 25 percent compared to the RTX 4080. The RTX 5070 model is expected to be in the 250 to 275 watt range, which represents an increase of around 13 to 15 percent compared to the RTX 4070.
These increased TDP values could have an impact on the choice of power supply. Users thinking about purchasing one of these new graphics cards may need to upgrade their power supplies to handle the higher power consumption. This is especially important for those running systems with a high number of other power-hungry components.
A table showing the possible TDP values of the upcoming RTX 50 series compared to the current models can help to illustrate the differences more clearly:
| TDP (RTX 40 series) | TDP (RTX 50 series) | Increase in percent |
|---|---|---|
| 450 W | 600 W | 33% |
| 320 W | 400 W | 25% |
| 200-220 W | 250-275 W | 13-15% |
However, actual power consumption in real-world applications may vary. Experience to date with the RTX 40 series shows that the cards often consume less energy in typical gaming scenarios than the specified TDP values. Only in particularly demanding applications, such as ray tracing or intensive GPU benchmarks, do the cards approach the specified TDPs.
Some power supply manufacturers such as Seasonic and Cooler Master have already included higher TDP values for the new NVIDIA GeForce RTX 50 “Blackwell” GPUs in their lists. This could be a further indication that the higher performance requirements are realistic.
At the moment, there is limited information on the technical specifications and exact configuration of the upcoming GeForce RTX 50 series. However, NVIDIA is expected to unveil the new generation at CES 2025. Until then, it remains to be seen what the actual specifications of the final products will look like. In the meantime, users should consider whether their current system is up to the demands of this new GPU generation or whether an upgrade is necessary.
