Mali-400 was announced in 2008, and since then has been used in various SoCs for smartphone, but now it’s mostly replaced by Mali-450 GPU in low cost mobile and STB SoCs, although Mali-400 is still being implemented in new SoCs such as Rockchip RK3128 processor. ARM has been working on a lower power version of the GPU, and just unveiled Mali-470 GPU targeting wearables, as well as embedded and IoT applications.
Mali-470 GPU is said to use the same memory and AMBA interfaces as Mali-400, while keeping some of the improvements brought to Mali-450 GPU, and further lowering power consumption to just half of that Mali-400 in terms of mW per frames per second.
Just like its predecessors, Mali-470 supports OpenGL ES 2.0, and like Mali-400 it will scale from 1 to 4 fragment processor, always combined with one single vertex processor. Mali-470MP1 is likely to be used in wearables or other applications with tiny displays and low power requirements, while Mali-470MP2 and Mali-470MP4 might also find their ways into more demanding applications.
ARM expects SoCs based on Mali-470 GPU to sample by Q2 2016, meaning we’ll probably start seeing Mali-470 GPU in actual devices in 2017.
