The Qualcomm Snapdragon S3 MSM8260 is an entry level SoC for smartphones and tablets (mostly Android based). It contains two Scorpion cores (enhanced ARM Cortex-A8) clocked at up to 1.5 GHz, a Adreno 220 graphics card and radio elements. Compared to the similar MSM8660, the 8260 does not include support for CDMA2000.
The similar named MSM8260A already contains the faster Krait cores and the slightly faster Adreno 225 graphics card.
The MediaTek MT8163 V/B 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 1.3 GHz. Furthermore, an ARM Mali-T720 MP2 graphics card clocked at 520 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/A is the faster version, with a CPU clock o up to 1.5 GHz and GPU of up to 600 MHz.
The performance is situated in the entry level of 2015 and often similar to the Kirin 910T (see benchmark below).
