The Register has a few more details - https://www.theregister.co.uk/2017/07/17/ibm_latest_mainframe_z14/ https://www.theregister.co.uk/2017/07/17/ibm_latest_mainfram... It features the next generation of IBM's CMOS mainframe technology, with a 10-core CPU chip using 14 nm silicon-on-insulator technology, and running at 5.2GHz, claimed to be the fastest processor in the industry. Each core has hardware accelerated encryption implementing a CP Assist for Cryptographic Function (CPACF). The CPU also has 1.5 times more on-chip cache per core compared to the z13. There can be up to 32TB of memory, three times the z13 maximum, and its IO is three times faster as well.
