NVIDIA's next-gen GeForce RTX 50 "Blackwell" GPUs such as the RTX 5090 & RTX 5080 will reportedly consume more power than the existing RTX 40 series.
NVIDIA GeForce RTX 50 "Blackwell" GPUs More Power Hungry Than RTX 40 Series: RTX 5090 Reportedly at 600W, RTX 5080 at 400W
Following up on his earlier post, Kopite7kimi suggests that the NVIDIA GeForce RTX 50 "Blackwell" GPUs will consume higher power than existing graphics cards under the RTX 40 "Ada" series. The leaker talks about at least three GPUs and their "potential" TDPs which are higher than what the current lineup consumes.
According to Kopite7kimi, the NVIDIA GeForce RTX 5090 will be rated at 600W, the RTX 5080 will be rated at 600W while the RTX 5070 will be rated above 220W. Compared to existing RTX 40 GPUs, the RTX 5090 will be rated at a 150W higher TDP since the RTX 4090 is rated at 450W, marking a 33 percent increase.
The NVIDIA GeForce RTX 5080 will be rated at 400W which is 80W higher than the RTX 4080 and RTX 4080 SUPER. This is an increase of 25%. It is also said that the GeForce RTX 5070 will also be higher rated than the 200/220W TDP of the RTX 4070 and RTX 4070 SUPER GPUs which may end up around 250-275W, marking a 13-15% increase in TDP rating.
Following is what the TDPs might look like for the GeForce RTX 50 "high-end" lineup:
- RTX 5090 -> 600W (RTX 4090 @ 450W) = +33% Increase
- RTX 5080 -> 400W (RTX 4080 @ 320W) = +25% Increase
- RTX 5070 -> 250W? (RTX 4070/S @200/220W) = ~15% Increase

Now the TDP rating doesn't reflect the real-world power consumption in gaming scenarios as we have seen with the RTX 40 "Ada" GPUs which consume much lower power than what their TDPs are rated at. The RTX 4070 SUPER series hardly does 200W, the RTX 4080 SUPER hardly does 250-280W while the RTX 4090 mostly sits at around 400W. It's just a few scenarios such as ray-tracing & GPU-heavy benchmarks that can push the graphics cards closer to their actual TDPs.
Earlier listings from PSU makers such as Seasonic and Cooler Master had also suggested higher TDP ratings for the NVIDIA GeForce RTX 50 "Blackwell" GPU lineup so it looks like there must have been some weight to those numbers.
As of right now, we know a few tidbits in regards to specifications and configurations of the next-generation GeForce RTX 50 lineup but rumors have suggested that the launch takes place next year at CES 2025 so there's sometime before we get to see the real details which are closer to the final products.
NVIDIA RTX 50 "Blackwell" Gaming GPU TDP "Preliminary" (Seasonic):
| GPU Name | TDP | Predecessor | TDP | Difference |
|---|---|---|---|---|
| RTX 5090 | 500W | RTX 4090 | 450W | +11% |
| RTX 5080 | 350W | RTX 4080 | 320W | +9.3% |
| RTX 5070 | 220W | RTX 4070 | 200W | +10% |
| RTX 5060 | 170W | RTX 4060 Ti | 160W | +6.2% |
| RTX 5050 | 100W | RTX 4060 | 115W | -13% |
