References

  • Change CPU options for an instance type based on the valid physical CPU core counts and threads-per-core values listed in this topic.

  • Hyper-threading (HT) runs two threads on a single physical CPU core as vCPUs. To use only physical cores, disable HT when specifying CPU options.
