The wheels keep turning from Mobile World Congress 2014 in Barcelona with Allwinner's announcement of the UltraOcta A80 SoC. Dubbed the "world's first big.LITTLE octa-core (8-core) heterogeneous SoC to included PowerVR Series6 GPU technology", the UltraOcta A80 combines four Cortex-A7 and four Cortex-A15 cores in a single chip design.
The UltraOcta A80 is aimed at tablets, portable game consoles, set-top boxes, media players and other devices that require "premium performance" level parts. The first devices will apparently hit "soon" but no other details were offered.
ARM is definitely on-board with Allwinner for this product as it is the poster child example of how the big.LITTLE design philosophy can be implemented to offer both high performance and low power results in one SoC. This chip is built on 28nm process technology and also includes high performance graphics with the PowerVR G6230 GPU. This GPU includes two "clusters" for a total of 64 ALUs (called cores in other SoC). Keep in mind that this Series6 GPU is about half the performance of the G6400 series included in the iPhone 5s and even Intel's new Merrifield and Moorefield processors.
The Allwinner UltraOcta A80 will also support 4K video encode and decode with H.265 thrown in for good measure. I am very curious to see the load on the SoC during these types of high quality video processes as the amount of acceleration on the chip isn't known yet.
