The RX 9070 XT Red Devil, a high-end variant of AMD's Radeon RX 9070 XT series, is notable for its substantial power consumption. It requires a minimum of a 900W power supply, similar to its predecessor, the RX 7900 XTX Red Devil[1][4][7]. This high power requirement is largely due to its factory overclocks and the inclusion of three 8-pin power connectors, which provide ample headroom for overclocking[7]. The typical board power (TBP) of the RX 9070 XT Red Devil is estimated to be around 400W, considering the system's overall power needs and the headroom for other components[1].
In comparison, Nvidia's high-end GPUs, such as the RTX 5080, recommend an 850W power supply, with a total graphics power (TGP) of 360W[1]. This suggests that while both AMD and Nvidia's high-end GPUs require significant power, the specific requirements can vary based on the model and its intended use.
The RTX 40 series from Nvidia is generally considered more power-efficient than AMD's offerings, with GPUs like the RTX 4070 delivering high performance while using less power than comparable AMD models[8]. However, the RX 9070 XT Red Devil's power consumption is more aligned with its performance capabilities and overclocking potential, making it a powerful choice for those who need high-end graphics processing.
It's worth noting that AMD's Frank Azor has mentioned that there will be RX 9070 XT variants with lower power supply requirements, offering consumers options for different power needs[1][7]. This flexibility allows users to choose between high-performance models like the Red Devil and more power-efficient alternatives.
