rylt :
Intel has a seperate power phase for the iGPU so it reads a bit differently
There isn't much of a standard for this though so the meaning can vary a lot between vendors. All those +s are for auxiliary rails and individual vendors could decide to tack a +N for the number of VRM phases they use for DIMM power, IO hub, termination voltages, bias voltages and anything else that requires its own odd voltage and we would end up with boards saying things like "8+4+3+2+2+1+1+1" phases without saying what gets how many phases.
More important than the number of phases (beyond the minimum required to safely meet power requirements) is how good they actually are.
With Haswell, a large chunk of the potential phase silliness goes away.
