I'm really surprised IBM doesn't offer a cloud product based on LinuxONE machines. These are ridiculously fast machines that are probably cheaper to build and run that the equivalent capacity in OCP x86 "boxes". And only IBM can have them.

Maybe because none of that is true? z/Architecture hasn't been (accurately) benchmarked in public for decades if ever.

I can tell you it feels very fast. The 5 GHz cores and the L4 cache, combined with the offloaded IO make it compare very favorably to similarly sized (and priced) x86 and POWER machines.
