Thought experiment - Mainframe

[kreien]

It is my first post here, and sorry in advance, if my theoretical question is stupid.

For me mainframes like IBM (see https://www.ibm.com/products/linuxone-4) are a big miracle – not liked but historically grown and irreplaceably at the same time. These machines are running nowadays with Linux and are good in database environments in conjunction with high number of transactions (finance, insurance etc.). When hashcat is strong with GPU, would be hashcat theoretically also strong in mainframe environments?

Was there ever a benchmark in such a mainframe environment? Think not, because mainframe supplier are not so talkative.

Thank you very much for a hint.

No, I don't believe anyone's benchmarked on a new-ish mainframe but I can guess how it'll go - CPUs are often hundreds of times slower than GPUs, even very strong CPUs are often beaten by low-end GPUs so a single 4090 would probably destroy basically any mainframe. (Again, this is just a guess and has a lot more nuance like specific hash types acting differently etc)
