Android sticks and ultra-cheap tablets are often powered by an AllWinner chipset, typically one using an old Cortex-A8 CPU design. The Chinese chipmaker has now updated its lineup with three new chipsets based on the new and power-efficient Cortex-A7.
One chip of particular interest, the AllWinner A20, packs a dual-core A7 CPU, which is up to 5 times more power efficient and offers 50% better performance than the A8. It’s fully certified to run Android 4.2.2 as well.
The chipset uses a dual-core Mali-400 GPU and packs an integrated TV decoder. The AllWinner A20 is pin-compatible with the A10 chipsets, so it should be easy for makers to slot in the new chip.
The other two chips, the A31 and A31s, are almost identical and use quad-core Cortex-A7 processors and a beefier PowerVR SGX544MP2 GPU.
All three chipsets can decode up to 2160p video (a.k.a UHD), including 3D video, and record 1080p in 3D. They have built-in HDMI 1.4 support too.
