Also it is not working simultaneously. For more read the below extraction from wiki,Octa-core variant This S4 version has Samsung's Exynos 5 Octa (octa-core) system on a chip (SoC) chip containing the first ARM big. LITTLE heterogeneous architecture central processing unit (CPU). The eight core CPU comprises a 1.6 GHz quad-core Cortex-A15 cluster and 1.2 GHz quad-core Cortex-A7 cluster. The cluster of four faster "big" A15 cores is paired with the cluster of four slower, more power-efficient "LITTLE" A7 cores. At any given time, either the big cluster is active (for maximum performance) or the LITTLE cluster (for maximum power efficiency). The switching of the active cluster is performed on demand by the chip firmware, with the migration of the running software from outgoing to incoming cores taking 20 µsec. The CPU emulates a single quad-core processor to the operating system and applications. The SoC also contains an IT tri-core PowerVR SGX 544 graphics processing unit (GPU). The GT-I9500 version of the S4 does not support LTE.[22] The E300K/L/S versions support LTE, with the Cortex-A15 also clocked at 1.6 GHz.<a href="https://en.wikipedia.org/wiki/Samsung_Galaxy_S4" target="_blank">https://en.wikipedia.org/wiki/Samsung_Galaxy_S4</a></blockquote>
