Recent days,a number of Chinese tablets brand out their quad core tablet.The chip,Allwinner A31,catches a lot of attention.Maybe there is something about A31 you can learn from here.

A31 quad core chip,planned to be used in tablets,smartphones and smart TV field, is presented by Zhuhai Allwinner Technology Corporation in 2012 December.
A31 based on quad core Cortex-A7 CPU architecture and Power VR SGX544MP2 GPU.The GPU has 8 cores and supports 4K and 2K video stream output and encode at the same time.Additionally,A31 configurates dual channel DDR which maximumly supports 64bit DDR3 and dual channel NAND Flash,16bit NAND Flast at most,dramatically improve read-write speed of system memory.What's more,A31 has optimised Power consumption management system,allwinner technology customizes a PMU chip AXP221 for A31,with the help of the AXP221 chip,A31 can efficiently control dynamic power;A31 also packs another special chip for superlow power control,so A31 can achieve long time standby.
The chip doesn't support bluetooth,which probably make some people away from it.

yep, pretty intresting chip there - if the allwinner a10 revolutioned chinese low cost smartphone-tablet market for how cheap it was (it basically created something akin to a market dump in china, with all phone makers jumping ship to allwinner and denying any prehesistent contracts) while being a pos on any other aspect, this one is actually good and fast.
shame tho for the missing bluethooth and gps support, it can be added with external chips but not being integrated in soc meant that really few makers will add them for costs reason.
