There's also digital probabilistic computing, with a processor working on AWS, and for the right workload ,claimed to be offering a very significant speed boost:
It's not mentioned in the article, but this hardware architecture may be better suited for brute-forcing password/crypto/key cracking than traditional computing architectures.
