Clock rates and overclocking reserves
The beat looks pretty good. In Full-HD and also WQHD in some places, the card already manages well over 2400 MHz in a cool state ex-works and even goes up to about 2450 MHz for a short time in some places. Fully warmed up and in Ultra-HD it is just under 2400 MHz, depending on the game and load in performance mode. If you increase the power limit, you can even increase the clock rate, because it stabilizes up to 2600 MHz and even a bit more, depending on the chip quality. With over 380 watts via the MorePowerTool (TGP), peak values of over 2.6 GHz were also feasible, but that’s actually more for the gallery, because you then also have to manually turn up the cooler… The then due power consumption is also no longer in relation to the performance, since the scaling decreases more strongly with the clock rate at some point.
GPU and GDDR6 memory temperatures
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 total can reach up to 110 °C at the peak, but in practice it was only just under 90 °C in Silent and around 95 °C in Performance BIOS (target for the fans). The “GPU diode”, internally called edge temperature by AMD (we also know it from NVIDIA), is clearly below that with values between 75 and 78 °C.
I was able to read out the GDDR6 with the help of a special engineering tool, and it is interesting that there are even two values per memory module, since it apparently outputs two sensors. The storage temperature is then weighted in the tool from these 16 individual values. The memory stays at a maximum of 87 °C inside (substrate), which is still an acceptable temperature, even in the long run. The highest readout values are likely to be generated by the two modules that lie above the tracks of the power supply.
This is also impressively proven by the IR images, where I intentionally operated the card without a backplate:
