据报道，AMD Radeon RX 9070 XT的功耗为304瓦，略低于RX 7900 XT的功耗。 RX 7900 XT通常在满载下消耗313瓦的大约313瓦，其中一些型号达到330瓦，尤其是那些像Hellhound合作伙伴型号这样的高工厂超频的型号，可以达到330瓦[1] [3]。
相比之下，RX 9070 XT具有304瓦的功耗，似乎提供了更有效的设计，尤其是考虑到它可以与RX 7900 XTX的性能相媲美，该RX 7900 XTX具有更高的功率要求[1] [5]。但是，值得注意的是，RX 9070 XT的自定义变体(例如Red Devil模型)可能由于工厂的超频而需要更大的电源，并建议整个系统提供900瓦的电源[4] [6] [6]。
总体而言，虽然RX 9070 XT的功率比标准条件下的RX 7900 XT少，但由于性能功能增强，定制模型可以提高电源需求。与某些前任和竞争对手相比，RX 9070 XT的效率也强调了其具有较低功耗的竞争性能的能力[7]。
