A reply to myself since I can't reply to the informative reply below (thanks HN). The RAM benchmarks for Xeon are per-machine (summed over sockets, presumably with no cross-socket traffic, since cross-socket memory is 1/2 speed) while the Power8 benchmarks are per socket.
That is indeed impressive. no wonder google is considering these. memory bandwidth is indeed critical.
