The OMPA 4430 is a dual-core ARM A9 part clocked at 1GHz built using 45nm CMOS process. It features Symmetric Multiprocessing (SMP) and an integrated POWERVR SGX540 graphics accelerator (supporting OpenGL ES v2.0, OpenGL ES v1.1, OpenVG v1.1 and EGL v1.3) for 3D games and UI. It also features IVA 3 hardware accelerators to allow full HD 1080p video encode/decode. The chip also features on-board USB 2.0 support.

Everything about the chip is designed with low power in mind.
