Chinese mobile chip manufacturer Allwinner has announced two new chips – the quad-core A31 and the dual-core A20. The chips are designed to be the heart of upcoming tablets, media PCs and set top boxes.

Both chips are using ARM Cortex-A7 processors and feature a significant boost in performance and graphics muscle, compared to the Cortex-A8 that powered the company’s current bestseller chip – the Allwinner A10.

Back to the new chips at hand, the Allwinner A20 is the more value oriented chip boasting a dual-core Cortex-A7 CPU with 512KB of L2 cache and 128KB of L1 cache. There’s a Mali 400 GPU on board supporting up to 2160p HD video playback. Additionally, the chip is backward compatible with the Allwinner A10 on pin-to-pin basis, meaning device manufacturers can upgrade their existing devices with the new chip without too much hustle.

The beefier quad-core Allwinner A31 sports 1MB of L2 and 256KB of L1 cache. The PowerVR SGX 544 is in charge in the graphics supporting 4K ultra HD video decoding.

Allwinner is leading the chip shipments in mainland China for 2012, supplying 22 million out of the 60 million chipsets powering the various super affordable tablets and low-power devices.
The Challenge is heating up and i LOVE IT biggrin.gif

Neat. Some China-tabs are pretty cool. I was considering an A10 based tablet, before I found a special offer on the Xoom 2 ME I have now.

On a side note, whenever I read Mali, I think of Malaria...

yes it is faster. Its a newer design chip. Its basically a die shrink with added specs.
it is more effecient and more powerful than a cortex a8

A good comaprison between chips

I for one cant wait for the A20 which SHOULD power more of them little android HDMI sticks. The current crop of Dual core are fine, but you always want more power smile.gif Since its backward compatible with teh A10, there should be new vesions of the MK802 sticks

Well it looks like they're more energy efficient but looking at the relative "estimated core performance" chart at the bottom it looks like A8 is still faster.

Thats DMIPS/MHz and it looks like the A7 can clock higher.

lol. Dont see how this is good news. All the specs are already a generation old and what we have had for a long time. And good luck getting enough memory bandwidth to play stuff at 2160p with those specs.
