Computation errors and GPU temperature : some numbers

By , the in Hardware - No comment
This is something we knew, but without being able to define the real impact. Our GPUs are more likely to produce computation errors than our CPUs. However, temperature seems to be a decisive variable in the growth of error probability. This news (in French) shows a small panel of nVidia cards from various architecture and the testing conditions.

Of course, the cards in desktop cases are the main focus, but the laptop or high performance computing rack cards are more likely to be subject to these issues because they run in a much more confined environment. The good news is that most modern GPUs (Fermi or Kepler) are kept away from erroring by efficient thermal protections.

This experiment consolidates our usual advice : avoid folding on laptop GPUs, and make sure that your sensitive components are correctly cooled.
