What are the power consumption differences between the AMD Radeon RX 9070 XT and the Nvidia RTX 5070 Ti

AMD Radeon RX 9070 XT:

- The RX 9070 XT, particularly the Red Devil variant, is reported to have a minimum system power supply requirement of 900W, which is not the power consumption of the GPU itself but rather a recommendation for the entire system[1][8]. This high requirement is largely due to the card's high factory overclocks and the system configuration it is intended for.
- Rumored specifications suggest the RX 9070 XT has a total board power (TBP) of around 304W, although some benchmarks indicate it could reach up to 329W[5]. Overclocked versions from AIB partners might consume up to 340W[7].

Nvidia RTX 5070 Ti:

- The RTX 5070 Ti has a confirmed TBP of 300W, making it slightly more power-efficient than the rumored RX 9070 XT specifications[2][4].
- In practice, the RTX 5070 Ti's power consumption can exceed its rated 300W under heavy loads, requiring a robust power supply and cooling solution[6].

Overall, while the RTX 5070 Ti is slightly more power-efficient based on its TBP, the RX 9070 XT's power consumption can vary significantly depending on the specific model and overclocking. The system power supply requirements for the RX 9070 XT are higher due to its high-performance configuration, but both cards are designed to deliver strong performance in their respective markets.
