Power draw

Alongside all of the frame rate testing today, I also used Nvidia’s PCAT tool to capture power draw figures over all 44 games that I benchmarked.

As you can see, there are some substantial differences in power draw between the two GPUs. The RX 7900 XT almost always drew between 320 and 325W of power regardless of the resolution. The 4070 Ti is much less power hungry though, particularly at 1080p and 1440p, where it drew less than 250W on average. Even at 4K, the average power draw is below 260W, or about 70W lower than the RX 7900 XT.

Performance per Watt

Considering those rather large differences in power, it quickly becomes clear that the 4070 Ti is significantly more efficient. The above charts show performance per Watt for each GPU – or how many frames are rendered per Watt. At 1440p for instance, the 7900 XT is actually 24% less efficient than the 4070 Ti. It does narrow the gap at 4K, but still remains 17% less efficient, something which is well worth factoring into any final buying decision.
