IBM has unveiled its Power11 servers and chips, designed to support AI, hybrid cloud, and automation applications.
Big Blue said Power11 will reduce complexity and improve workload efficiency by up to 28 percent when peak performance isn’t required.
Set to be generally available across high-end, mid-range, and entry servers – the E1180, E1150, S1124, and S1122 –as well as IBM Power Virtual Server in IBM Cloud, Power11 will also be the first IBM Power server to support the company’s Spyre AI chip, first introduced last year.
Described as a “high-end server built for the AI era,” the E1180 server offers up to 256 Power11 cores and 64TB of DDR5 memory, while the midrange 4U rack-mounted E1150 – designed for data-intensive workloads – supports up to 120 Power11 processor cores and 16TB of DDR5 memory.
The S1124, a second 4U server which offers compute, memory, and hybrid cloud flexibility for enterprise and regional data centers, supports up to 60 IBM Power11 cores and 8TB of memory, while the 2U S1122 supports up to 60 IBM Power11 cores and 4TB of memory.
The new servers offer up to 55 percent better core performance compared to Power9, up to 45 percent more capacity with higher core counts in entry and mid-range systems compared to Power10, and twice the performance per watt compared to comparable x86 servers, IBM said.
Furthermore, by offering an uptime rate of 99.9999 percent, IBM said the servers are the “most resilient server in the history of the IBM Power platform,” providing zero planned downtime for system maintenance and less than one-minute guaranteed ransomware threat detection with IBM Power Cyber Vault.
“IBM Power11 changes the game for enterprise computing,” said Tom McPherson, GM for power systems at IBM. “With Power11, clients can accelerate into the AI era with innovations tailored to their most pressing business needs. We are taking advantage of the full IBM stack to deliver hybrid cloud, AI, and automation capabilities while building on our decades-long reputation as a trustworthy hybrid infrastructure for essential workloads.”
IBM Power11 will be generally available July 25, 2025, while the IBM Spyre accelerator is expected to be available in Q4 2025.
