Table C.1.1. CPW values for Power System Models
*Note: 1. These models have a dedicated L2 cache per processor core, and share the L3 cache between
two processor cores.
2. Memory speed differences account for some slight variations in performance difference
between models.
3. CPW values for Power System models introduced in October 2008 were based on IBM i 6.1
plus enhancements in post-release PTFs.
