Power Generation Graph
This site's five-generation dataset (Power7 through Power11) comparing cores, memory architecture, performance, IBM i OS ceiling, energy efficiency, and lifecycle status across the full modern Power lineage.
The Power Generation Graph is the standout dataset on this site, published at /power-generation-graph/ and driven by data/power-generation-graph.json. It is the reference point every migration-path page on this site, and its Power8/Power9/Power10/Power11 siblings, draws from when comparing what a given generation offers against what came before or after it.
