Cracking WPA Passwords With a GeForce Graphics Card


In this news about WFI passwords cracking, I said that NVIDIA GeForce GPUs allowed to crack passwords around 100 times faster than a modern CPU. I stumbled upon this post where the author has tested the ElcomSoft Distributed Password Recovery software to crack WPA passwords. He has compared several solutions and here are the results:

  • GeForce GTX 260 GPU: 10000 passwords / second
  • Core 2 Quad @ 2.4GHz CPU: 1000 passwords / second
  • Core 2 Duo @ 1.86GHz CPU: 400 passwords / second
  • GeForce 9400M GPU: 178 passwords / second

From these results, we see the 100 times factor is a bit excessive. The real factor is around 10 times faster: 10,000 passwords/sec for the GPU against 1,000 for the quad core CPU. But if we look at software documentation, we see that up to 4 GPUs per computer can be used. Then 4 GeForce GTX 260 should be crack 40,000 passwords/sec and compared to the 1.86GHz Core 2 Duo performance, we have a 100 times factor…
