"Consumer electronics, mobile devices and embedded sensors are now the new partners of the extreme scale supercomputing community, because they share the same requirements for plentiful, powerful and inexpensive components that consume little power." I wonder if this community aiming to perform embarrassing parallel workloads in the Exascale range before the end of the decade will focus their efforts in the first place on mobile chips over graphics chips? While consuming a considerable amount of power and costing in the range of $600 p. board they can perform an amazing amount of FLOPs. The AMD HD 5970 has a processing power of respectively 4.64TFlops (single precision), 0.93TFlops (double precision) respectively, while have a maximum power consumption of 294W. By reading quotes like "It is completely clear that GPUs are now general purpose parallel computing processors with amazing graphics, and not just graphics chips anymore" (Jen-Hsun Huang, co-founder and CEO of NVIDIA) I wonder how ARM chipsets (do they even support Double precision?) will be able to come even close to these numbers considering power efficiency and costs?
