Stress tests in detail: Testing graphics cards correctly (Tutorial – Part 1)

Unigine Valley

The power consumption is one tick lower than with "The Witcher 3" and 3DMark "Sky Diver", but you can run this test very nicely as an endless loop without having to buy a Pro version. However, the somewhat old benchmark is already quite suitable for cooling and stability tests. In addition, it also runs smoothly on older hardware and can therefore be used universally.

By selecting the right screen resolution with maximum settings, you can also optimize the generated load very well, as long as you stay on average over 25 FPS.

Even if the CPU load is quite low and the API is no longer dew-fresh, errors that could occur due to an unstable overclocking, one finds with it quite, although not immediately and in full. However, the fact that this program is freely available makes it a tip even today. Download here.

Review – medium power consumption
– Medium GPU temperature for cooling test
– sufficiently high package temperature for stability tests
– medium storage temperature
Suitability – a useful stability test, especially for older weaker hardware
– Use in the endless loop possible

Unigine Superposition

"Superposition" should also make everything better than its predecessors as a stress and stability test, especially on very potent hardware. We can only confirm this in part, because compared to the tests listed so far, the power consumption and temperature are more likely to be in the rear midfield. In addition, the individual runs are not 100% reproducible in the result, which results in a tolerance range that is actually far too high for a benchmark. The free download can be found here.

However, it is advantageous that you can run "superposition" in the endless loop. With a little patience you will also find the optimal presets, so that some load is generated. However, certain memory errors occur here rather than e.g. Unigine "Valley", so that one should keep an eye on "superposition" at least as a supplementary stability test. This also applies to the achievable clock rates, which are significantly higher than those of e.g. "The Witcher 3 ". Thus, lower load can also unintentionally provide useful benefits. As the sole test, however, "Superposition" is rather unsuitable.
