Power, Thermals and Noise
For power testing, we use an outlet power meter, which I know is not perfect but it’s repeatable and accurate enough to show the disparity between changes in the platform. All parts remained the same between tests with only the GPU changing. Just keep in mind this is the full system load power consumption while looping the Heaven benchmark.
The power readings for the RX 5600 XT has it right above the GTX 1660 SUPER under load, with an idle wattage about 2 watts lower, but idle is hard to quantify, so no points for either house on this one.
For our thermal testing, we ran Gaming loads rather than a power virus type of load as this represents a far more realistic loading scenario for those looking to see what you can expect when gaming on your new RTX card.
When testing thermals we find that the RX 5600 XT with the Thicc II Pro cooler the GPU never reaches 70C under stock operation. Idle, however, the RX 5600 XT shows around a 1-2C higher temp than we see on the other parts in this range. While Navi may be very efficient and 7nm, as you can see even the very small Navi 5500 XT also idled at around 31C as well which is indicative of being expected for the new µarch.
The fan noise for the RX 5600 XT Thicc II Pro, is not even audible under stock operation and did not ramp much when pushing the clock as the temps only increased a few degrees. Overall the cooler is well suited for this card and works very well, both thermally, and acoustically.
