I'm confused about the physical configurations I get from dedicated hosts. According to the instance type matrix, an m4.16xlarge
instance is powered by (not sure how many) Intel Xeon E5-2686 v4 CPUs, so I imagine if I launch one of the dedicated instances, I'll get to use the entire E5-2686 CPUs, however many are there. Right?
But I'm confused now. The instance type matrix says that an m4.16xlarge
instance has 64 vCPU's. But as according to Intel, an E5-2686 v4 has only 18 cores / 36 threads. What does this mean? Do they put two CPUs in an m4.16xlarge machine? Couldn't find any reference for this.

m4 are dual socket, see the table on this page (seems not updated to reflect the new size yet): https://aws.amazon.com/ec2/dedicated-hosts/pricing/
So the host should have 36 physical cores, 72 threads of which 64 threads can be used for ec2 instances.
