NVIDIA’s RTX 5090 cracks MD5 password hashes at 220 GH/s and was tested on 231 million unique leaked passwords collected by Kaspersky from the dark web. >One card cracked 48% in under one minute >60% in less than one hour >77% in one year The speed gain over the RTX 4090 is small because most passwords follow weak patterns like common words with numbers or birth years. Cloud GPU rentals make this power cheap and easy to access, and the results show poor password habits and reuse across accounts are the biggest security risk. Strong unique passwords from a password manager, plus two-factor authentication and passkeys where possible, are the best protection.
