Overview
- Apple announced the A20 Pro for the iPhone 18 Pro lineup, describing it as the company’s first iPhone system-on-chip built on a 2nm process and the chip that will power iPhone 18 Pro, iPhone 18 Pro Max and iPhone Duo.
- The company detailed a six-core CPU with two new high-performance “super” cores it says are up to 20% faster, a redesigned seven-core GPU it claims is up to 40% faster, and two Neural Engine units totaling 32 cores with twice the FP8 inference throughput.
- Apple moved memory off the top of the chip to wafer-level multi-chip module (WMCM) packaging so DRAM sits beside the SoC, a change Apple says removes DRAM from the chip’s thermal path and lets the phone sustain higher performance for longer.
- Apple supplied device-level claims that the iPhone 18 Pro can deliver up to 40% more sustained performance than the iPhone 17 Pro and twice the sustained performance of the iPhone 16 Pro, but the company did not publish low-level clock speeds or cache sizes.
- Independent verification is pending: leaked Geekbench 6 results and third‑party reports suggest very high single‑core and multi‑core scores and rumored clock speeds, yet those figures remain unconfirmed until wider benchmarks and supplier disclosures appear.
