A spy shot of ARM's mobile processor architecture roadmap has been leaked, and it includes a new powerful CPU core family, codenamed Artemis, which will be done at the next 10nm die shrink. Given that currently 14nm is the bleeding edge, this roadmap ensures we will be witnessing drastic improvements in the power consumption/performance ratio for the foreseeable future. Device chipsets built on the 10nm production process aren't expected before 2017, so there's plenty to look forward to.
We are also seeing the new low-power Cortex-A35 line fleshed out a bit more. It will take over wearables, or the LITTLE part in big.LITTLE architectures soon, and will be built both on the current 16nm/14nm nodes, as well as on 10nm ones, when the technology becomes available for mass production. In store are new graphics processing units, too, that are still with their codenames Mimir, Egil and Gemini, so it's anyone's guess what the GPU future holds.
