In 2011, researchers created a tool called Cloud Cracking Suite capable 
of testing 50,000 SHA-1 passwords per second using eight Amazon nVidia 
GPU instances.

Last year, a similar project stuffed 25 AMD GPUs in a 4U sized box. It 
is capable of testing just shy of 350 billion NTLM passwords per second. 
Four such boxes -- 100 GPUs -- running in parallel can surpass the 
trillion passwords per second mark. Total cost is less than $50K.

The NSA has computing facilities measured in acres.
