Sapphire RX 7900 XTX Nitro+ Review

We use Nvidia PCAT to measure power draw of the graphics card only, with readings from both the PCIe slot and the PCIe power cables combined into a single figure. We use Cyberpunk 2077 (4K) for this testing.

Sapphire has pumped up the power significantly with the Nitro+, with the card drawing 440W in our testing – clearly the extra 8-pin power connector is not just for show!

That does mean overall efficiency of the card is significantly reduced – with performance per Watt down by 17% compared to the reference card, but hopefully we can tap into some of this extra power headroom when overclocking…
