Under the covers, its Xen virtualization running on 2x E5-2670 CPUs - with the 32 vCPU instance, you are basically getting the entire physical server with a little overhead for the virtualization part.
3.5x (based on the price) 630000 = 2205000
Basically same bang for buck, mine is slightly better. My bad experience with Amazon was based on the normal EC2 instances, so thanks a lot for the tip about the spot instances. Although having a root is very convenient.
Sorry for slightly offtopic.
edit: corrected calculation
