There are industry-standard benchmarks that measure TPS. See for example (or maybe not even for example; it may be effectively the only one in town) http://www.tpc.org/information/benchmarks.asp.
And of course, anybody considering buying such a machine will spend quite a bit on evaluating how it performs under their load, just like SPEC (https://www.spec.org/) says something, but not all.
I've looked at the tpc.org maybe 13 years ago. It never made sense to me to use it as a measurement unit back then and it still don't make sense to me now. :)
Because they are not arguing with scientists but with "decision makers". So bullshit is more important than proven facts... Tanksfully, banks are moving slowly out of mainframes. You'll never find a new business going on a mainframe. Mainframes users are captive, not free.

But how can they claim they can do X transactions when a transaction's processing requirement is undefined?
