The newer version of cpuinfo as reflected in this post seems to have the necessary components to differentiate between multi-core cpus.
cpu cores physical id core id.
Physical ID assigns a Unique ID to each CPU.
CPU cores reflects the number of Cores making up the CPU
core Id: identifies the core represented.
