Are you sure that it won't have Bluetooth?

About perfomance - it won't be absolutely top, as A7 is battery time oriented CPU, slower than A9, and much slower than new A15.

@igorek7

This is not a good site, and it has zero relation to Onda.

Bluetooth without Bluetooth wireless audio profile [Advanced Audio Distribution Profile (A2DP)] support cannot play on Bluetooth speakers, it is good for keyboard & mice only. Ampe A10 quad seems to be not supporting A2DP.

I dont understand chinese but it seems that it has got Jelly Bean 4.1. That is great.

According to good sources it'll have Bluetooth.

Brian Klug talked about the A31 in Anandtech: http://www.anandtech.com/show/6604/more-details-on-allwinners-a31-quad-core-a7-soc

And I saw (in Engadget or The Verge, don't remember) that Polaroid launched 2 tablets, one 7'' dual-core and one 10'' with the A31 - and the A31 performed worst than the dual core version.

I think that the A31 tablets will have great battery life, but not good performance - especially with a Retina display. I have the first version of the newest iPad and it struggles to cope with the screen sometimes - hence the new version was launched.

@Vitaliy_Kiselev I'm not talking about benchmarks, it's about real use.

The A31 have amazing specs for HDMI-output video (4K in 30 fps), and I truly believe it - the A10 could run "2160p" without breaking a sweat. But I have my doubts in system display rendering - which is made by the GPU.

I totally agree with you that the first iPad Retina was underspecced - and it have a SGX543MP4 (4-core) GPU. The A31 have a newer GPU version (SGX544) but only dual-core - and I doubt that the 544 have doubled the 543's performance. The impact is not only in games and 3d apps.

But the biggest problem is the poor optimized firmwares made from the chinese manufacturers. I have a PipoU1 (RK3066, dual core A9, quad-core Mali400 GPU, 1280x800 IPS screen), and I love the little beast for my primary purpose - see video while commuting to work. But the performance of Jelly Bean in the tablet is way underoptimized - much less fluid than, say, ICS in a Galaxy SII, a phone with much less processor power than this tablet. And the firmware have a lot of little glitches never ironed out by the manufacturer - and will never will, the last firmware update was in november, and since a new model already came out (U1Pro), probably will never have another update. And the tablet was not supported by Cyanogenmod.

For some uses (like mine), chinese tablets have a very good price-performance ratio. But for others - and especially for people that want rock solid stability and performance - they are not.

My onda v812 is on the way. This model without retina display, just 8" 1024x768 ips, but other specs are the same - Allwiner A31,2gb, 4k, Wifi direct, etc. Hope it wil connect with gh3.

I have got it. V812 playing 4k demo video without any problem. Now will try HDMI out, and after will try to play my own 4k files, just need to convert it from R3D.
