Specops compared Nvidia H200, AMD MI300X and RTX 5090 GPUs using Hashcat across MD5, NTLM, bcrypt, SHA‑256 and SHA‑512 to measure password‑cracking performance. The RTX 5090 outperformed both AI accelerators, showing consumer GPUs can be more cost‑effective for cracking and underscoring the need for long passphrases, breach detection, and MFA. #RTX5090 #ActiveDirectory
Keypoints
- Benchmarks using Hashcat across MD5, NTLM, bcrypt, SHA‑256 and SHA‑512 compared Nvidia H200, AMD MI300X, and RTX 5090.
- The RTX 5090 outperformed both AI accelerators on every tested algorithm.
- AI accelerators like the H200 are far more expensive but do not deliver proportional password‑cracking gains.
- Older consumer GPU rigs (e.g., an eight‑card GTX 1080 setup) can match or exceed modern AI hardware for cracking.
- Effective defenses include enforcing long passphrases, continuous breached‑password scanning, and deploying multi‑factor authentication.
