CPU Blocks S130 nRF51

[nordicdev]

Is it possible to have different characteristic of CPU blocks (I mean different number of CPU blocks or similar) with the same firmware running on two different nRF51 boards connected to app with connection interval of 20msec to 75msec?

I am talking about the CPU blocks that happen during Bluetooth activity (devzone.nordicsemi.com/.../)
