Host Name racdb2.mwallet.ccd.infosys.com
Platform Linux x86 64-bit
CPUs 80 <--
Cores 40 <--
Sockets 4

Hi ,
I have a two node RAC on RHEL.
I saw the following in my AWR in terms of configurations. Though the number of 
cores are same, the number of CPUs are different. Will it make any difference 
in performance and load balancing?

Host Name

Cores

Sockets

Memory (GB)

racdb1.mwallet.ccd.infosys.com

Linux x86 64-bit

Also kindly let me know the difference between CPU and core.

Thanks and Regards,
