iPhone Duo A20 Pro Chip and Performance
Apple iPhone Duo is powered by Apple’s flagship A20 Pro chip, built on TSMC’s cutting-edge 2nm process node. It matches the exact core specifications and performance architecture of Apple’s standard Pro flagship series.
Six-Core CPU Architecture
Apple iPhone Duo’s A20 Pro chip continues Apple’s classic heterogeneous 2 + 4 core layout:
- 2 Super Cores: These cores are dedicated to processing intensive, heavy single-threaded tasks like 4K video rendering, complex real-time audio, computational photography, and heavy multi-tasking.
- 4 Efficiency Cores: These cores, clocked at 64 GHz, run background tasks and daily routines, drawing minimal power to extend battery efficiency.
The 4.93 GHz Maximum Clock Speed
The reported 4.93 GHz maximum clock speed applies to the two primary Super Cores, offering desktop-class peak frequencies (reaching nearly 5.0 GHz), thermal and power efficiency, and dynamic burst frequency (ramps up to 4.93 GHz during short).
