Power8 vs Power9 Performance Facts for IBM Model S924

ibm-power9-s924-9009-42a IBM Power9 S924 9009-42A Specifications
This specification breakdown of the IBM Power9 9009-42A model S924 will explain the key performance features that sets it apart from its Power8 predecessor.
 
In comparison to the 8286-42A model S824, the IBM Power9 S924 delivers 40-50% better performance for data intensive database and analytics workloads, with over twice the memory footprint (accelerated by Coherent Accelerator Processor Interface CAPI) running at speeds up to 344 GB/s (172 GB/s per socket), has over 60-70% more CPW for IBM i workloads and 2X the I/O bandwidth (Gen4 PCIe slots). IBM Power9 with CAPI 2.0 increased I/O bandwidth over 4X Power8 ability, clocked at 192 GB/s. The Power9 S924 also has PowerVM virtualization is built into the Power9 processor chip, which increases performance, server utilization and cloud enables your data.
