How does the power requirement of the RX 9070 XT compare to Nvidia's RTX 5080

AMD Radeon RX 9070 XT

The RX 9070 XT, particularly the Red Devil variant, is reported to require a minimum power supply of 900W for the entire system, although this is likely due to its high factory overclocks and not indicative of all RX 9070 XT models[1][7]. Frank Azor, AMD's Chief Architect for Gaming Solutions, has confirmed that there will be RX 9070 XT variants with lower power supply requirements, and many models will use 8-pin power connectors for easier compatibility with existing power supplies[1][4]. The typical board power (TBP) for the RX 9070 XT is rumored to be around 304W, which is lower than some of the more powerful Nvidia GPUs[6].

Nvidia GeForce RTX 5080

In contrast, the Nvidia GeForce RTX 5080 requires a system power supply of at least 850W, with a total graphics power (TGP) of 360W[2][5]. This is significantly lower than the system power requirement for the RX 9070 XT Red Devil but still reflects the RTX 5080's high performance capabilities. The RTX 5080 uses the newer 12V-2x6 power connector, which is not as widely supported as the traditional 8-pin connectors used by many AMD GPUs[5].

Comparison

- Power Supply Requirement: The RX 9070 XT Red Devil requires a higher minimum system power supply (900W) compared to the RTX 5080 (850W), though not all RX 9070 XT models will have this high requirement.
- GPU Power Consumption: The RTX 5080 has a TGP of 360W, while the RX 9070 XT has a TBP of around 304W, indicating slightly lower power consumption for the AMD card.
- Connectors: The RTX 5080 uses newer 12V-2x6 connectors, whereas many RX 9070 XT models will use traditional 8-pin connectors, offering broader compatibility with older power supplies.

Overall, while both GPUs are powerful, the Nvidia RTX 5080 is generally considered more capable in terms of raw performance, but the RX 9070 XT offers competitive pricing and potentially easier upgrades due to its power connector choices[3][4].
