Apple has officially launched the iPhone 17 series with major performance and AI improvements. The lineup debuts with two new chipsets, one is the Apple A19 and the other is the Apple A19 Pro. While both processors share a lot in common, some notable differences set them apart. Here’s a detailed breakdown of what sets the new iPhone 17 chipsets apart, starting with the configuration.
Both chips are manufactured on TSMC’s 3nm (N3P) node, ensuring better efficiency and performance compared to earlier generations. They feature the same 6-core CPU setup with 2 performance cores and 4 efficiency cores with performance cores clocked at 4.26GHz. This makes them nearly identical in terms of CPU design and power efficiency.
The real difference lies in the GPU –
iPhone 17 Air uses the A19 Pro but with a cut-down 5-core GPU, similar to the standard A19. Both chips support hardware-accelerated ray tracing, but the extra GPU core on the Pro models gives them an edge for gaming and graphics-heavy applications.
Both chipsets focus heavily on on-device AI performance.
Apple has equipped them with a 16-core Neural Engine, powering new iOS 26 features like real-time photo enhancements, live translation, predictive text, and more. These tasks run directly on the device, improving both speed and privacy.
Apple introduced a new vapour chamber cooling system with the iPhone 17 Pro series allowing the A19 Pro to sustain higher performance during demanding tasks like gaming or 4K video editing.
Benchmarks show only single-digit percentage gains in raw performance, but the biggest improvement is in sustained workloads, where the A19 Pro maintains peak performance longer than the A19.
Memory and cache also differ –
The Pro models also unlock exclusive features such as ProRes RAW support and an upgraded ISP (Image Signal Processor) for improved photography and videography.
The A19 series introduces Apple’s new N1 wireless networking chip, supporting Wi-Fi 7 and Bluetooth 6. For 5G, Apple takes a split approach –
This gives Pro models broader 5G support while the Air prioritises battery efficiency.
In conclusion, both the Apple A19 and A19 Pro are powerful and efficient chips designed for the latest iPhone 17 series. The A19 Pro stands out with better GPU performance, larger RAM and cache, ProRes RAW support, and improved thermal management, making it the clear choice for power users, gamers, and professionals.
Answer. The A19 Pro features a 6-core GPU, 12GB RAM, and 6MB L2 cache, compared to the A19’s 5-core GPU, 8GB RAM, and 4MB cache.
Answer. Yes. Both include a 16-core Neural Engine for on-device AI tasks and support Wi-Fi 7, Bluetooth 6, and Apple’s new N1 wireless chip. However, 5G modem types differ by model.
Answer. Thanks to its vapour chamber cooling system, the A19 Pro maintains peak performance longer during demanding tasks like gaming and 4K video editing, unlike the standard A19.
