China's Allwinner also has an octa-core chip, touts powerful graphics
Samsung, MediaTek, Huawei and even Qualcomm are now in the octa-core SoC game, but there's always space for more. The latest member is China's Allwinner Technology, who's best known for making the chipsets inside many low-end devices. Like most of its competitors, Allwinner's UltraOcta A80 silicon (pictured above on a development board) uses ARM's big.LITTLE heterogeneous multi-processing design, meaning it can simultaneously run on all eight cores -- four low-power Cortex-A7 and four high-end Cortex-A15. The chip also features Imagination Technologies' 64-core PowerVR G6230 GPU, which promises to deliver "a twofold increase in graphics" performance when compared to Allwinner's previous flagship SoC, the A31 series. We'll spare you from all the nitty-gritty, but you can learn more in the source links below. Expect to see the UltraOcta A80 in affordable devices "in the next few months."
Samsung to outline 8-core big.LITTLE ARM processor in February
Samsung's processor design team has been on a roll with fast chips this year with the Exynos 4 Quad and Exynos 5 Dual. Based on its agenda for the International Solid-State Circuits Conference, that momentum isn't about to stop. A company presentation at the event on February 19th will delve into a new heterogeneous, 8-core processor that relies on ARM's concept of big.LITTLE computing: one half is a quad-core, 1.8GHz ARM Cortex-A15 that will do all the heavy lifting, while the other is a quad 1.2GHz Cortex-A7 that takes over in quieter moments. We don't know much more about the chip beyond the expected 28-nanometer manufacturing process, but it's easy to see a mobile chip that's fast without having to consume much energy in its downtime. Most of the mystery surrounds where Samsung will launch the processor first, rather than what it can do: the big.LITTLE chip would be most valuable in a smartphone, but a potentially large size could relegate it to tablets early on.
Rivals AMD and ARM unite, summon others to become 'heterogeneous'
Rumors of a hook-up between AMD and ARM have been circulating ever since someone coined the phrase "the enemy of Intel is my friend." As of today, however, that alliance is real and cemented in the form of the HSA Foundation -- a non-profit organization dedicated to promoting the dark arts of Heterogeneous System Architecture. It's a relatively old concept in computing, but the Foundation's founding partners (AMD, ARM, Imagination Technologies, MediaTek and Texas Instruments) all stand to gain from its wider adoption. How come? Because it involves boosting a chip's performance by making it use its various components as co-processors, rather than treating them as specialized units that can never help each other out. In other words, while Intel pursues Moore's Law and packs ever-more sophisticated transistors into its CPUs, AMD, ARM and the other HSA pals want to achieve similar or better results through parallel computing. In most cases, that'll mean using the graphics processor on a chip not only for visuals and gaming, but also for general tasks and apps. This can already be achieved using a programming language called OpenCL, but AMD believes it's too tricky to code and is putting mainstream developers off. Equally, NVIDIA has long had its own language for the same purpose, called CUDA, but it's proprietary. Whatever niche is left in the middle, the HSA Foundation hopes to fill it with an easier and more open standard that is not only cross-OS but also transcends the PC / mobile divide. If it works, it'll give us a noticeable surge in computational power in everyday apps by 2014. If it fails, these new-found friends can go back to the less awkward custom of ignoring each other.
