Modern mainframes are quite powerful machines: "The dual frame z14, launched in July 2017, and the single frame z14, launched in April 2018, are based on the z14 chip, a 10-core processor running at 5.2 GHz. A z14 system can have a maximum of 240 Processing Unit (PU) cores, 170 of which can be configured to the customer's specification to run applications and operating systems, and up to 32 TB usable redundant array of independent memory (RAIM), some of which can be configured as Virtual Flash Memory (VFM). Each PU can be characterized as a Central Processor (CP), Integrated Firmware Processor (IFP), Integrated Facility for Linux (IFL) processor, Integrated Information Processor (zIIP), Internal Coupling Facility (ICF) processor, additional System Assist Processor (SAP) or as a spare." https://en.wikipedia.org/wiki/IBM_zEnterprise_System https://en.wikipedia.org/wiki/IBM_zEnterprise_System
