AMD's RDNA 4 architecture and RX 9000-series GPUs launch March 6, beginning with the mainstream to high-end 9070 and 9070 XT. The new chips come with significantly improved ray tracing and AI hardware and should provide Nvidia's RTX 50-series some much-needed competition.

When it comes to power usage, AMD says the RX 9070 XT has a TBP of 304 W with a recommended PSU wattage of 750 W, while the RX 9070 has a mere 220 W TBP with a 650 W power supply recommendation. Those are some impressively low power figures, particularly given the performance claims.
