Physical processor to Logical Processor ratio

Hi Experts !

I came across this old blog post on Physical processor to Logical processor calculation.

http://blogs.msdn.com/b/virtual_pc_guy/archive/2010/08/13/using-powershell-to-find-the-virtual-processor-to-logical-processor-ratio-of-hyper-v.aspx

The straight formula I see here is

Write-Host (@(Get-WmiObject -Namespace "root\virtualization\v2" -Class MSVM_Processor).count / (@(Get-WmiObject -Class Win32_Processor) | measure -Property NumberOfLogicalProcessors -Sum).Sum) "Virtual Processor (s) per logical processor" -ForegroundColor yellow

As per this formula, My Hp Blade server BL460c with 2 X Intel(R) Xeon(R) CPU E5-2670 0 @ 2.60GHz, 2600 Mhz, 8 Core(s), 16 Logical Processor(s) can have 2.125 Virtual Processor (s) per logical processor

I have 32 Logical Processors and can have have 68 Virtual Processors in this case.

Is this assumption correct?

Is this formula applicable for even an AMD processor?

Cheers.
