IBM's Power11 chips feature cores that are up to 55 percent faster than the previous Power9 generation. Unlike competitors, Power11 maintains a maximum of 30 cores per socket but supports up to 240 threads due to its 8-way simultaneous multithreading. Additionally, the new resource groups firmware aims to enhance performance without significantly increasing energy consumption. Power11 claims twice the performance per watt compared to x86 systems, with a focus on resiliency that includes expected uptime of 99.9999 percent and zero-downtime maintenance capabilities.
IBM's latest Power11 chips offer impressive performance gains with cores up to 55 percent faster than Power9. However, they retain a maximum of 30 cores per socket.
Power11 chips utilize 8-way simultaneous multithreading, enabling a 30-core socket to manage as many as 240 threads, significantly enhancing parallel processing capabilities.
The new chips introduce resource groups as a firmware feature to optimize utilization and boost performance with improved energy efficiency, resulting in a 28 percent efficiency gain.
IBM claims that Power11 systems achieve twice the performance per watt of comparable x86 systems while ensuring 99.9999 percent uptime and zero-downtime for maintenance.
