The iPhone 8 and 8 plus are powered by an A11 Bionic chip, featuring a six-core CPU design with two performance cores that are 25 percent faster and four efficiency cores that are 70 percent faster than the A10 Fusion, offering industry-leading performance and energy efficiency. Its second-generation performance controller can harness all six cores simultaneously, delivering up to 70 percent greater performance for multi-threaded workloads, giving customers more power while providing the same great battery life.
A11 Bionic also integrates an Apple-designed GPU with a three-core design that delivers up to 30 percent faster graphics performance than the previous generation. All this power enables incredible machine learning, AR apps and immersive 3D games.
All of this processing power is housed in a beautiful glass back design made with the most durable glass ever in a smartphone in four beautiful finishes: space gray, silver, gold and red. The glass finish is made using a seven-layer color process for precise hue and opacity, delivering a rich depth of color with a color-matched aerospace-grade aluminum bezel, and is water and dust resistant. The glass back design enables a world-class wireless charging solution. Wireless charging works with the established Qi ecosystem.
Still an incredibly powerful phone, 3 years after its release, it represents fantastic value, especially when buying second hand or refurbished.
