The Apple A11 Bionic is a System on a Chip (SoC) from Apple that is found in the iPhone 8, iPhone 8 Plus and iPhone X. It was announced late 2017 and offers 6 cores divided in 2 performance cores and four power efficiency cores. In comparison to the A10X all 6 cores can be used at once, leading to a much higher theoretical performance. In our benchmarks the SoC however is not only faster in multi threaded tests (+77% versus A10 Fusion in Geekbench), but also in single threaded tests (+19%). Apple states 25% more performance compared to the A10 in the iPhone 7.
With 4.3 Billion transistors, the A11 Bionic is a rather big chip especially compared to the Snapdragon 835 (3 Billion) or a Skylake desktop quad-core Soc (1.75 Billion).
