Samsung is using a PowerVR SGX543 GPU inside its upcoming Exynos 5 Octa instead of its usual ARM Mali GPU.

The A6 SoC used inside the iPhone 5 is a custom core from Apple, that is much more efficient architecture wise, than other competing SoCs found in Android devices.

Apple has just unveiled the iPhone 5 and the device is packed with technological advancements. Along with LTE and support for 5GHz WiFi, Apple has also managed to pack in dual-A15 SoCs inside the handset.
