Hey Maurice!

 $ lscpu | grep 'Model name:' | sed 's/Model name: *//'
Intel(R) Celeron(R) CPU  J1900  @ 1.99GHz

 $ gcc -c -Q -march=native --help=target | grep '^  -march=' | sed 's/= */=/g' | tr -d '\t'
  -march=silvermont

Although this is new, we've done silvermont optimizations on Intel Atoms in the past.

analyzing CPU 0:
  driver: intel_cpufreq
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 20.0 us.
  hardware limits: 1.33 GHz - 2.42 GHz
  available cpufreq governors: ondemand, userspace, performance, schedutil
  current policy: frequency should be within 1.33 GHz and 2.42 GHz.
                  The governor "performance" may decide which speed to use
                  within this range.
  current CPU frequency is 2.42 GHz.
