The Power11 processor is designed to deliver higher clock speeds and can add up to 25% more cores per processor chip than comparable IBM Power10 systems. The Power11 processor builds upon the key capabilities we delivered with Power10 including stronger reliability, availability, and serviceability (RAS) characteristics, better energy efficiency and energy management, and improved quantum-safe security. Beyond the processor itself, we are introducing the following improvements to packaging, memory architecture and AI acceleration :
- Packaging Innovation : The Power11 processor will leverage new integrated stack capacitor (ISC) technology and advanced 2.5D packaging along with innovations in cooling such as improved heatsinks and more efficient fans to optimize energy delivery, improve thread and core strength and increase system capacity.
- Enhanced System Architecture : The robust memory architecture for Power11 systems will be based on the recently released DDR5 DDIMMs and enhanced OMI interfaces which enable improved memory reliability, capacity, and bandwidth. Given that OMI is technology agnostic, the Power11 portfolio built on the Power11 processor will also support OMI DDR4 memory migrated from Power10 high-end systems, enabling clients to protect their investments in memory technology.
- AI Acceleration : We continue to support a range of emerging enterprise AI use cases with the MMA (Matrix-Math Accelerator) architecture. Improvements to Power11 processor core strength and system capacity will improve the performance of the MMA for inferencing workloads. Furthermore, IBM intends to incorporate the IBM Spyre accelerator into Power11 offerings to provide additional AI inferencing capabilities. Working together, IBM Power processors and the IBM Spyre accelerator will enable the next generation infrastructure to scale demanding AI workloads for businesses.
