Allwinner announces the quad-core A31 and dual-core A20 chipsets with Cortex-A7 CPUs

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.
