The AMD Radeon RX 9070 XT is designed with a total board power (TBP) of 304 watts, which is a measure of the power consumption under full load, including both the GPU and other components like memory[2][3]. This power requirement is typical for the standard version of the RX 9070 XT. However, some custom models, such as the PowerColor Red Devil variant, may have higher power requirements due to factory overclocking. These custom models can recommend a minimum power supply of 900 watts for the entire system, not just the GPU[4][7]. This higher recommendation accounts for additional system components and provides a safety margin to ensure stable operation under heavy loads.
The RX 9070 XT uses the Navi 48 GPU, which is part of the RDNA 4 architecture, and features 64 RDNA 4 Compute Units, 64 Ray Accelerators, and 128 AI Accelerators[2]. It operates at a game clock of 2400 MHz and a boost clock of 2970 MHz, providing a high level of performance[2]. The power consumption of the RX 9070 XT is relatively efficient compared to its performance capabilities, making it competitive in the market.
In terms of power connectors, the standard RX 9070 XT typically uses two 8-pin connectors, which can supply up to 375 watts. However, some high-end custom models might use a single 16-pin connector capable of delivering up to 600 watts[6]. This variability in power connectors reflects the different design approaches by various manufacturers to meet the needs of different users and system configurations.
