The hardware used in this benchmark isn't very well chosen. All the systems have a different number of cores (Power 16, AMD 32, Intel 40), and the AMD system has the additional disadvantage over the others of being 1P instead of 2P, which approximately halves the available cooling and correspondingly limits clock speeds. The results aren't very surprising given that.
Making comparisons like this can make sense when one of the competitors doesn't make an equivalent product, but they all do make products with an equivalent number of sockets and cores.
