Radeon RX 6950 XT
The card boosts above 2.6 GHz in gaming mode and still just below 2.6 GHz when warmed up a bit more. Thus, it is significantly higher than what AMD officially states. It’s up to you to decide what you want to add, but a better cooling system is better than even more power.
The temperatures of the MSI card are still within the green zone with 76 degrees, but the hotspot already scratches the 95 °C mark and leads to clock reductions. The cooler already has clear problems with the over 400 watts in places, unfortunately.
Now let’s move on to the recording with the high-resolution infrared camera. Optris’ PI640 features a true 640 x 480 pixel bolometer and records at up to 30 FPS. Here I use the normal lens and calibrated film with a known transmittance so that I can de facto see inside the closed housing. I deliberately do not remove the backplate because it is primarily involved in cooling. However, the temperatures of the exposed PCB areas are plausible and match the sensor readings.
Radeon RX 6750 XT
The card boosted above 2.7 GHz in gaming mode and still just below 2.7 GHz when warmed up a bit more. Thus, it is clearly above what AMD officially states and also above the clock of its very big sister.
The temperatures are a good 66 to 67 °C, with the hotspot at 85 to 86 °C. This is already much better and cooler. Nothing throttles yet, despite the higher power consumption compared to the RX 6700 XT.
Thermography also shows nothing to the contrary:
Radeon RX 6650 XT
The smallest card always boosts above 2.7 GHz in gaming mode and when gaming, even when fully warmed up. This puts it well above the other two cards.
The temperatures are actually great, too. With the huge cooler, the card does not manage over 64 °C for the edge temperature and the hotspot is also still unsuspicious at a maximum of 77 °C.
This is also confirmed by thermography:
