AMD Server replacement to Microsoft to reduce core count

Hello,

Our servers are about 5 years old and nearing replacement age. I was hoping to replace them with lower core count machine so as to spend less on the new (relatively) MSFT core based licensing.

Can someone guide me on what would be a replacement for 

4 socket AMD Opteron 6272 2.1 GHz 16 Turbo CORE, 16M L2/16M L3, 1600Mhz Max Mem

From what I understand AMD's do not have "real" core since they lack the floating point calculation engine.

I would prefer to replace it with a 2 socket 32 core Intel system.
