> And by the way few people do math "heavy lifting" with x86 CPUs today, they would rather do it in a GPU This depends on the workload, really; some workloads are quite GPU-unfriendly. In any case, the supercomputer in question---Tianhe-2 [2]---derives most of its computing power from the Xeon Phi [1], a x86-ish many-core vector processor which looks much like a GPU.
