Real achievable clock rates and overclocking
The clock rates and the readout are simple this time. While the GPU clock is at 2895 MHz in cold state, it then levels off permanently at 2860 MHz two Bost steps lower after a complete warm-up. You can definitely leave that alone. With manual OC and pushing the TBP limit, it also goes up to 3 GHz, but then the card becomes even more inefficient and you cannot reach the GeForce RTX 4080 in any case. The 20 to 25 percentage point gap simply cannot be made up.
GPU temperatures in the case
The differences are not as big as feared if you use a decent case. If you close the panel, the GPU temperature (Edge) increases by 2 Kelvin, the GDC hotspot increases by up to 4 Kelvin. Nevertheless, the rates of 61 °C (Edge) and 69 °C (Hotspot) are nothing to be afraid of. The massive cooler is a real icebox.
Infrared measurements (heat flow analysis)
Let’s start with the gaming loop and we can see that the voltage converters are pushing the small cooling frame a bit too hard, especially since the MOSFETs from Alpha & Omega are not really top-of-the-line models. Unfortunately, only MSI knows why the coils are cooled unnecessarily via the large cooler and not the VRM.
In the stress test, the temperatures in the voltage regulators continue to rise, but what we just wrote also applies here. The cooling is anything but optimal at this point.
