The A18 Pro is built on the 3nm manufacturing node, but this is the second-generation manufacturing process, which is more refined and efficient. The A18 Pro houses the “fastest CPU in any smartphone” and consists of 6 cores – two main cores doing the heavy lifting and four energy-efficient cores. Put together, they outperform the A17 Pro’s CPU by 15% while using 20% less power.
As for the GPU, it gets a desktop-class architecture and can outperform its predecessor by 20% and can do ray tracing twice as fast.
The improved memory bandwidth and the larger cache size allow the A18 Pro get some “Advanced media” features support. Those include a ProMotion display supoprt, Always-on display support, faster USB 3 speeds and ProRes video recording. These features are all unavailable on the regular iPhones.
