All of the top devices in the Geekbench charts for Android and iOS are now flaunting 10nm chipsets - Android has the Snapdragon 835 and Exynos 8895 on top, while Apple's new phones with A11 topped the charts immediately after their first pass in the benchmark database. As you can see above, the single-core scores of the iPhone 8, 8 Plus, or the iPhone X, are more than twice higher than anything Android has to offer, and more than 50% higher in the multi-core runs. Even if we see a move to the 7/8nm process for the spring flagships next year, they still might not be able to top those result anyway.
This goes to show that Apple's A11 Bionic is a cyborg of a chipset indeed, capable of real-time augmented reality, or recording 4K video at 60fps without a sweat. This time around, Apple also has a custom-made graphics and image processing engines inside, so the Bionic might be with the most optimized power/performance ratio that Apple has ever created, and it really shows both in synthetic benchmarks, and during the announcement event demos that Apple showcased on stage.
