I know Galaxy S4 has an “Octa Core” CPU (Central Processing unit) . Do all eight cores operate at the same time?

     (GT-I9505 CPU uses a 1.9GHz Quad Core, and GT-I9500  uses a 1.6GHz Octa Core that has been

       optimized according to country and region.)

 

 

 

 

 

 

No, the Eight cores do not  operate at the same time. The Octa Core is composed of Cortex A15 processor 1.6Hz

      Quad(“Big”) and low power Cortex A7 processor 1.2GHz Quad (“Little”). The Galaxy S4 uses the “big”-core or the “little”-

      core depending on the requirement of the feature in use.

 

     Applications (e.g. like Games) that require high-performance CPU mainly operate in the “big”-core, applications (e.g. like       

     Email, message) mainly operate in the “little”-core.
