I stopped by Allwinner today to discuss their recently announced and now-shipping A31 SoC. The A31 is based around four ARM Cortex A7 CPUs and a Power VR SGX544MP2 GPU, all built on TSMC's 40nm G process. 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. 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. GPU clocks on the SGX544MP2 are...
