Apple A20 Chips in iPhone 18 models rumoured to feature new design
Apple’s upcoming A20 chips for the iPhone 18 series are expected to feature a new design, moving away from TSMC’s current InFO packaging. Some chips will integrate RAM directly on the same wafer as the CPU, GPU, and Neural Engine, improving performance and power efficiency for longer battery life. Manufactured using TSMC’s advanced 2nm process, these changes are likely to benefit higher-end models launching in late 2026, with lower-end versions arriving in early 2027. Overall, the A20 represents a significant upgrade in Apple’s chip technology for the next iPhones.
