I’ve seen some misleading information about Hyper-V logical processor or CPU numbers support. Some people are taking the operating system edition, e.g. Enterprise or Data Center numbers and applying them to Hyper-V. DO NOT DO THIS. The actual support is 32 Logical Processors or Cores, e.g. 16 Dual Core or 4 * 6 Core CPU’s. Here are the limitations for Hyper-V R2.
