The gaming performance on a graphics card is the most important factor in buying a card, but you also need to be concerned about the noise, temperature and power consumption numbers.
At idle on our open air test bench we were sitting at around 30C for the GPU and GPU hotspot temperatures with no fan noise. After playing PUBG for over an hour at 1440P we found that the temperatures topped out at 61C on the GPU temperature sensor and 79C on the GPU hot spot. Our testing on the AMD Radeon RX 6700 XT reference card hit 79C on the GPU temperature and 99C on the GPU temperature hot spot. So, the MERC319 6700XT card by XFX is delivers 18-20C better load temperatures! It was also 1-3C cooler than the Sapphire NITRO+ RX 6700 XT. It is the largest of the three cards, so we are glad that it was able to cool the best!
The Sapphire NITRO+ RX 6700 XT was significantly quieter than the AMD Radeon RX 6700 XT reference card. Our sound meter found it was 3.1 dBA quieter while gaming once the fans were ramped up to operational speed.
For testing power consumption, we took our test system and plugged it into a Kill-A-Watt power meter. For load numbers we ran Rainbow Six Siege at 1440P and recorded the peak power number while the in-game benchmark was running. This is done to ensure the results are repeatable.
Power consumption on the AMD Radeon RX 6700 XT peaked at 389 Watts and we peaked at 394 Watts on the XFX Speedster MERC319 Radeon RX 6700 XT. There is no significant power consumption difference between the two models.
