25 GPUs devour password hashes at up to 348 billion per second. Five 4U servers equipped with 25 AMD Radeon-powered GPUs linked together using an Infiniband switched
Any approximate time needed to crack this password let's say from state sponsorship with 5000 cluster computers ? (cluster PC are with a tons of GPU-s each for cracking)
Suppose the Russian government wants your password. Cracking your password is not necessary. They put a bug in your computer, your house or put a gun to your head. You can't stop a state. The government where I live in is not allowed to put you a gun to your head to find your password.
