Apple‘s new A19 and A19 Pro chips are both built on TSMC’s 3nm (N3P) process, but they are fundamentally different. The A19 powers the iPhone 17, while the more advanced A19 Pro is found in the iPhone 17 Pro and Pro Max.
Core Specifications & Performance


| Feature | A19 (iPhone 17) | A19 Pro (iPhone 17 Pro) |
| CPU | 6-core (2 performance, 4 efficiency) | 6-core (2 performance, 4 efficiency) |
| GPU | 5-core | 6-core |
| RAM | 8GB LPDDR5X | 12GB LPDDR5X |
| L2 Cache | 12MB (system cache) | 32MB (system cache) |
| Cooling | Standard | New vapor chamber cooling system |
Sustained performance is the key differentiator. While both chips have the same CPU core count, the A19 Pro’s larger cache, extra GPU core, and new vapor chamber cooling allow it to maintain peak performance for longer without thermal throttling. This gives it a significant advantage in demanding applications like gaming and 4K video editing.
Exclusive Features

The A19 Pro is built to handle professional-grade tasks and has features not found on the standard A19 chip. These include:
- ProRes RAW support for professional video capture.
- More advanced on-device AI models that leverage the larger cache and enhanced thermal management.
- The new vapor chamber cooling itself is a key feature, enabling a 40% better sustained GPU performance for heavy workloads.
