Allwinner work on A83T 8-core Cortex-A7 SoC

A83T

Allwinner just posted on Twitter and made press release on their web that they work on new octa core processor named A83T.

So far there are no much info than it will be on 28 nm TSMC process and will be very power efficient. If we make analogy with A20 and A23/A33 the A83T will be lower cost feature cut version of A80.

The 8 cores will run up to 2Ghz! They name the architecture big.LITTLE but with 8 Cortex-A7 cores it should be more little.LITTLE 🙂

The question is how many applications will use all 8-cores? We all know the many-core is more sale buzzword than real performance improvement for most of the daily use cases.

At least in PC world 2 core at higher frequency will feel faster than 4 core at lower frequency for most of daily work and 4-core benefit will be seen just in some software products which really use the 4 cores.

As always software is way behind the hardware development.

A80 Octa core BigLittle SoC from Allwinner will be ready in 2014

Eva Wu from Allwinner marketing sent me the new logo for A80.

There is no much info about it yet, but it will be 8 core (4xCortex-A15 and 4xCortexA7) and Allwinner is working now on it. Probably it will have 8-16 GPU co-processors too, we hope these to be MALI but there are great chances these to be PowerVR like A31, Eva is silent on this.

This new 8-core SoC will position Allwinner again on top of Rockchip which work on Cortex-A12 and have now RK3188 which is the most productive Chinese SoC with 4-core Cortex-A9.

It’s great to see how these two companies penetrate in such fields where the Western companies dominated just few years ago and now are in the league where the big boys Samsung. Mediatek, Qualcomm etc are playing.

With 8-core the small linux computers will become desktop productivity. Let’s hope Allwinner will keep the SATA, Gigabit Ethernet, HDMI like in A20.
