A19 Pro puts Neural Accelerators in every GPU core

Apple announced the A19 Pro alongside the iPhone 17 Pro on September 9, 2025. Its 6-core GPU carries Neural Accelerators built into each core, which Apple says work together with the 16-core Neural Engine to power AI models, graphics and games. The company states that the chip enables running large local language models on the phone.

The A19 Pro also has a 6-core CPU that Apple calls the fastest in any smartphone, along with a larger cache and more memory than the A18 Pro. Combined with a vapor chamber cooling system, Apple puts sustained performance at up to 40 percent above the previous generation.
