Total power with the RX 5700 XT is about the same as what we saw with the RX 590 we’ve tested, placing this closer to NVIDIA’s RTX 2070 SUPER. The non-XT RX 5700 was a closer to the RTX 2060 SUPER, tied with the GTX 1070 Ti.

Clearly getting the highest performance possible out of these Navi GPUs was a higher priority than power savings, just as we saw with the 7nm Radeon VII. We are still looking at far lower power than a Vega 64, and higher performance to boot. Things are moving in the right direction.

Temperatures and Noise

While temps and noise will vary based on load (and eventual aftermarket cooler designs), what we observed with these reference designs was about what one might expect from a blower-style cooler. Temps are fine, with 76 C (hot spot/tJunction at 94 C) from the RX 5700 XT and 66 C (hot spot/tJunction at 77 C) with the RX 5700, both in a ~25 C room.

As to noise levels, these are indeed controlled, with 31 – 31.6 dBA at idle and a max of 48.5 – 48.6 dBA from both cards on the open test bench. Manually tuning the fan profile will provide lower temps, but these will start to get loud quickly. AMD has struck a pretty good balance between temps and noise with these cards, and the sound did not carry a “whine” and was easier to ignore as a result.
