This is yet to be seen, i'd say this is exactly like the AMD case, advertising 8 cores, which it in a sense did have but as each core had to share the FP scheduler with another they were not classed as individual "cores". The phase counting should be the same, 1 capacitor, 1 choke and 1 controller, this is what is considered a phase and always was until doublers got added. If the VRM has to share a controller then its not a full phase, just like a bulldozer core sharing an FPU. There is no definition on what a "core" is but the courts agreed that due to previous iterations by AMD themselves and their competition that these were not built in the same way as all other "cores" and advertising them as 8 cores is misleading
I don't disagree that there is nothing wrong with power delivery systems that use this setup, as a lot of them do and work extremely well but this is misleading in the same way.
