EE Times reports NVIDIA is betting on ARM to be more efficient for supercomputers than x86:
In a recent interview, Nvidia’s Sumit Gupta, director of Tesla marketing, said the only real advantage to x86 systems was that they could run operating systems like Microsoft Windows faster, but that when it came to needing maximum performance on minimum power, ARM was the future, and therefore a better option for supercomputing.
ARM architecture, explained Gupta, emerged out of the embedded space, where power limitations were prevalent and where less than a watt of power was considered a norm. All performance was therefore constrained from the conceptual phase of the chip’s design, forcing engineers to be especially creative about power efficiencies.
Intel and AMD’s x86 architecture, on the other hand, had been designed with PCs in mind, and came from a world in which machines were typically plugged in to wall sockets and faced no real power limitations.
