- Main processors: S5L8900, S5L8720, S5L8920, S5L8922, S5L8930, S5L8940, S5L8942, S5L8945, S5L8950, and S5L8955.
- Baseband processors: PMB8876, PMB8878, XMM6180, MDM6600, MDM6610, MDM9x00.
Instruction set
The following Instruction Sets are being used:
- ARMv6: S5L8900 and S5L8720
- ARMv7: S5L8920, S5L8922, S5L8930, S5L8940, S5L8942, S5L8945, S5L8950
