Tests show $30,000 AI GPUs are terrible password crackers — RTX 5090 gaming GPU outperforms Nvidia H200 and AMD MI300X

Tests conducted by Specops revealed that expensive $30,000 AI GPUs like Nvidia's H200 and AMD's MI300X performed poorly compared to consumer graphics cards like Nvidia's RTX 5090 in password cracking. Despite the significant price difference, the RTX 5090 outperformed the other GPUs by 20% over the MI300X and 63.7% over the H200 on average. The RTX 5090 excelled due to its design with more INT32 cores, which are crucial for password cracking, while the AI GPUs prioritize different instructions for their machine learning tasks. This study underscores that consumer desktop GPUs remain the most efficient for password cracking tasks.
