¹ IBM z16 with the Crypto Express 8S card provides quantum-safe APIs, providing access to quantum-safe algorithms, which have been selected as finalists during the PQC standardization process conducted by NIST. Source: https://csrc.nist.gov/Projects/post-quantum-cryptography/post-quantum-cryptography-standardization/round-3-submissions (link resides outside ibm.com). Quantum-safe cryptography refers to efforts to identify algorithms resistant to attacks by classical and quantum computers. This aims to keep information assets secure even after a large-scale quantum computer has been built. Source: https://www.etsi.org/technologies/quantum-safe-cryptography (link resides outside ibm.com). These algorithms help with the integrity of several firmware and boot processes. IBM z16 is the industry-first system protected by quantum-safe technology across multiple firmware layers.

DISCLAIMER: Compared 5 IBM Machine Type 3931 Max 125 model consists of three CPC drawers containing 125 configurable cores (CPs, zIIPs or IFLs) and two I/O drawers to support both network and external storage versus 192 x86 systems with a total of 10364 cores. IBM Machine Type 3931 power consumption was based on inputs to the IBM Machine Type 3931 IBM Power Estimation Tool for a memo configuration. Power consumption of x86 was based on March 2022 IDC QPI power values for 7 Cascade Lake and 5 Ice Lake server models, with 32 to 112 cores per server. All compared x86 servers were 2- or 4-socket servers. IBM Z and x86 are running 24 x 7 x 365 with production and nonproduction workloads. Savings assumes a Power Usage Effectiveness (PUE) ratio of 1.57 to calculate more power for data center cooling. PUE is based on Uptime Institute 2021 Global Data Center Survey (link resides outside ibm.com). CO2e and other equivalencies that are based on the EPA GHG calculator (link resides outside ibm.com) use US National weighted averages. Results might vary based on client-specific usage and location.
