Extended 8-phase = 4x PWM signals + doubler IC in interleaving mode
Twin 8-phase = 4x PWM signals each to two power stages
Load step from 45A to 193A. What you see is the transient response, ie the resulting output voltage with load changes. It's not that the VRM has less droop, it's that the VRM is faster at adapting to the new load scenario resulting in less undershoot.

Twin 16-phase (8 PWM signals, each connected to two power stages).
