Really? Only Apple?? What about Qualcomm or Cavium? Arm cores are now in the premier systems offered by Cray and HPE. See here for comparison to Skylake for Crays system: https://twitter.com/simonmcs/status/930425114922958848 Here for HPE’s: https://twitter.com/hpc_guru/status/930194415787888642 there’s also the Centriq from Qualcomm, I think there were some numbers posted at the goingarm HPC users group. Bottom line, there are plenty of super fast Arm processors that match or beat the best Intel can put out.
