The value proposition (if I may use that terminology) of mainframes is not performance -- it's 'RAS' (reliability, availability, serviceability). Of course, if you've got a huge legacy codebase of COBOL and CICS, it might be more a matter of 'keeping the lights on' for the business.

Sure you can do more MIPS on a cluster of generic underpowered x86 boxes, but what happens if you remove a RAM stick, shoot a bullet through an SSD or are hit by an earthquake? The numbers alone are hard to compare if the guarantees are totally different. A second thing to count is that it’s vastly cheaper to run thousands of services out of a small group of very large machines than to run the same workload on a large number of cheap machines.
