Clock rates and overclocking reserves
The beat thing looks really good. In Full-HD and also WQHD in places, the card manages well over 2420 MHz and in places it even goes up to about 2560 MHz for a short time. Fully warmed up and in Ultra-HD it’s still between 2350 and 2500 MHz, depending on the game and load. If you increase the power limit by the maximum possible 15%, then the clock rate can even be increased a bit, because it stabilizes up to 2600 MHz and even a bit more, depending on the chip quality. For a short time peaks of about 2650 MHz were visible, but only for a short time and only for the gallery. However, the 391 watts that are then due are no longer in relation to the performance, since the scaling decreases more strongly with the clock rate at some point. 
Temperatures GPU and GDDR6 memory
Now let’s look at the temperatures. AMD still uses the so-called hotspot temperature internally, but now solves this much smarter and with more and cleverly positioned measuring points or sensors. The sum can reach up to 110 °C at the peak, but in practice it was only just over 63 °C. The “GPU diode”, internally called edge temperature by AMD (we also know it from NVIDIA), is clearly below that with the values.
I was able to read out the GDDR6 with the help of a special engineering tool. It is interesting to note that there are even two values per memory module, since the memory also has twice the capacity and apparently outputs two sensors. From these 16 single values one weights then in the tool the memory temperature, which I have given you in the diagram once with. The memory remains, even in the long run, inside (substrate) at just over 56 °C, which is a more than acceptable temperature. The highest readout values are likely to be generated by the two modules with no heatpipes running over their heatsinks. The difference between the individual modules is up to 4 degrees!
This is also impressively proven by the IR images, where I intentionally operated the card without backplate in each case. When gaming with Control in UHD, everything looks pretty decent…
.. and Furmark also hardly produces significantly higher rates.
