MacRumors • • technology
Key Points:
- Apple introduced the A20 Pro chip in the iPhone 18 Pro and iPhone 18 Pro Max, featuring a new 2nm architecture and a 6-core CPU with two "desktop class" super cores that are up to 20% faster.
- The redesigned 7-core GPU delivers up to 40% faster graphics performance and enhanced memory bandwidth, with new neural accelerators doubling FP8 performance for on-device large language model processing.
- The A20 Pro includes a 32-core Neural Engine that offers twice the compute power of its predecessor, improved efficiency, and support for 8-bit floating point math, aimed at advanced on-device AI models.
- Apple emphasized advanced thermal management with custom silicon packaging inspired by M-series chips, directly connecting silicon and memory to the vapor chamber to sustain peak performance.
- Compared to previous generations, the iPhone 18 Pro's A20 Pro chip provides 40% more sustained performance than the iPhone 17 Pro's A19 Pro and double the sustained performance of the iPhone 16 Pro's A18 Pro.
