Performance metrics have been in the crossfire lately. We have MHz, IPCs, QuantiSpeed and PR ratings and all of them are somewhat arbitrary definitions of performance. To add to the list of metrics, we propose a novel metric and that is Power Per Cubic Inch or PpCI. According to the PpCI rating, and I don't see why we should not use this metric, the SS50 is beyond any doubts a performance megastar of galactic proportions.
