How many vCPUs do I need in AWS?

Choose an Amazon EC2 instance type with 16 vCPUs. The Windows operating system recognizes these 16 vCPUs as eight cores, so licensing has no negative impact. For more information on how many vCPUs are equivalent to a physical body, see Physical Cores by Amazon EC2 and RDS DB Instance Type on the AWS website.

How many cores does an AWS CPU have?

m4. 4xLarge instances have 16 logical CPUs, so it looks like your EC2 instance reports that it has a single socket, with one physical CPU with eight cores. Each core can run two threads simultaneously (Intel Hyperthreading technology), presenting each core as two logical CPUs.
