Read the product brief

IBM z16™ is the latest iteration of IBM Z® mainframes with on-chip AI inferencing and industry-first quantum-safe technologies.¹

Bring AI and cyber resiliency to your hybrid cloud to speed insights and protect data now against future threats. IBM z16 features the groundbreaking IBM Telum™ processor at its core. It has industry-first on-chip integrated accelerators to predict and automate with AI at unprecedented speed, scale and extremely low latency. 

Choose from a single-frame, multi-frame or rack mount to fit your workload optimization and infrastructure needs.

z16 and the infusion of AI into z/OS

Discover how deploying AI on the IBM z16 Telum processor brings transformative benefits to mainframe environments.

TCO and CO2e calculator

Try the TCO calculator to example how to:

  • determine CO2e emission differences between x86 and IBM® LinuxONE and Linux on Z running similar workloads;
  • consolidate per core licenses to drive TCO savings; and
  • reduce IT costs by running enterprise software on IBM LinuxONE and Linux on Z

Answer a couple of questions to get a personalized total cost of ownership estimate for IBM LinuxONE and Linux on Z.
