Succession

z14 was a z/Architecture-based microarchitecture designed by IBM and introduced in 2017 for their z14 processors and mainframes. The z14 microarchitecture replaced the z13.

Process Technology

z14-based microprocessors are manufactured on GlobalFoundries's 14 nm FinFET Silicon-On-Insulator (SOI).

Architecture

Key changes from z13

  • 14 nm process (from 22 nm)
  • Higher clock frequency (5.2 GHz from 5 GHz)
  • Higher scalability
    • Up to 170-way multiprocessing (from 141-way)
  • Core
    • Improved Operand Store Compare (OSC) prediction
    • Faster branch wakeup
    • Improved instruction delivery
  • Cache
    • New directory design
      • Power efficient
    • L1I$ increased to 128 KiB/core (from 96 KiB/core; 33% increase)
    • L2D$ increased to 4 MiB/core (from 2 MiB/core; 100% increase)
    • L3$ increased to 128 MiB/CP (from 64 MiB/CP; 100% increase)
    • New 672 MiB/drawer of shared L4
  • Central Processor Assist for Cryptographic Function (CPACF)
    • Dedicated co-processor for each core
    • Claims 6x faster encryption functions (vs. z13)
      • 4x Advanced Encryption Standard (AES) speedup
    • Support for True Random Number Generator
    • New support for SHA-3 standard
