Allwinner says that the A31 is starting out with a price of around $20 but fully expects this to go down to half or even lower during its life cycle. Allwinner also claims to have built its own video encode and decode blocks for the A31 which is what enables the platform to decode UHD (4K) content at 30 FPS. GPU clocks on the SGX544MP2 are around 350 MHz or higher as well. I asked for details about CPU and GPU clocks since these weren't readily available in the launch announcement, and was told that A31 was shipping with the A7s clocked at 1.0 GHz, although the platform could go higher to around 1.2 GHz if an OEM chooses. In addition there's a fifth power saver (likely A7) core on A31 which has a lower frequency, an arrangement curiously similar to NVIDIA's shadow core - this core is likely synthesized for better power efficiency. The A31 is based around four ARM Cortex A7 CPUs and a Power VR SGX544MP2 GPU, all built on TSMC's 40nm G process. I stopped by Allwinner today to discuss their recently announced and now-shipping A31 SoC.
