Average Bandwidth on Xeon Machine

Hello,

I am running the bandwidth analysis on the xeon machine using intel vtune. 

The summary of the result shows average bandwidth 

Average Bandwidth

Package    Bandwidth, GB/sec

package_0    6.718

package_1    7.657

 

Can you please explain me what package refers here? If application is running with single thread, which package value I should pick for the bandwidth.

Regards,
