The Apple A6 is a dual-core SoC found in the iPhone 5 with ARM compatible CPU cores. The A6 was developed by Apple and supports the extended ARMv7s instruction set. The clock rate of the CPU is between 800 to 1200 MHz depending on the CPU load. The integrated GPU is a PowerVR SGX543MP3 at 266 MHz.
The MediaTek MT8163 V/A is an ARM based entry-level to mid-range SoC for (Android based) tablets. It offers four ARM Cortex-A53 processor cores (quad-core) that are clocked with up to 1.5 GHz. Furthermore, an ARM Mali-T720 MP2 graphics card clocked at 600 MHz, a DDR3x32 1600Mbps memory controller, Bluetooth 4.0, 802.11 b/g/n, GPS and FM are integrated in the SoC.
The similar named MediaTek MT8163 V/B is the slower clocked version, with a CPU clock o up to 1.3 GHz (-6%) and GPU of up to 520 MHz (-13%).
The performance is situated in the entry level of 2015 and often similar to the Kirin 910T (see benchmark below).
