A19 Pro vs A19: Key Differences in Performance and Specs

Apple has detailed its new iPhone 17 series processors. The A19 Pro and A19 chips power the latest devices. Both are built on TSMC’s advanced 3nm technology.

A comprehensive specs leak reveals major internal differences. The chips are more distinct than Apple’s marketing suggests. This creates a significant performance gap between Pro and standard models.

Cache and Memory Configurations Define the Gap

The A19 Pro and A19 share the same 6-core CPU architecture. Their clock speeds are reportedly identical for single and multi-core tasks. Performance divergence comes from cache and memory.

The A19 Pro features a massive 22MB L2 cache. The standard A19 is limited to just 12MB. This cache advantage allows the Pro chip to access data far more quickly.

Memory bandwidth also separates the two. According to the leak, the A19 Pro’s LPDDR5X RAM runs at 9,600MT/s. This delivers a bandwidth of 75.80GB/s. The standard A19 operates at a slower 8,533MT/s for 68.26GB/s.

GPU Core Architecture Shows Stark Contrast

The graphics processing unit reveals the largest divide. The A19 Pro in the iPhone 17 Pro Max uses a 6-core GPU design. It contains 96 execution units and 768 arithmetic logic units.

A binned A19 Pro version powers the new iPhone Air. Its GPU is reduced to 5 cores, 80 EUs, and 640 ALUs. The standard A19 matches this binned Pro chip’s EU and ALU count but remains a 5-core part.

This architectural split ensures a clear graphics performance hierarchy. Pro users will see benefits in gaming and pro-grade applications. The Neural Engine, however, is a consistent 16-core design across all variants.

The internal architectural choices confirm a deliberate performance stratification. Apple’s A19 Pro vs A19 specs reveal a calculated divide to segment its flagship iPhone lineup.

Info at your fingertips

What is the biggest difference between the A19 Pro and A19?

The biggest differences are in cache size and GPU architecture. The A19 Pro has nearly double the L2 cache and a more powerful GPU with more execution units, leading to significantly better graphics performance.

Does the standard A19 have less RAM?

Yes. Reports indicate the standard A19 is paired with 8GB of RAM. The A19 Pro models are configured with a faster 12GB LPDDR5X memory package, further widening the performance gap.

Is the CPU speed the same on both chips?

Yes. Both the A19 Pro and A19 feature a 6-core CPU with identical clock speeds. This means basic computational tasks will feel very similar on both iPhone 17 models.

Which iPhone models use the A19 Pro chip?

The full A19 Pro is used in the iPhone 17 Pro and Pro Max. A slightly binned version of the A19 Pro, with a less powerful GPU, is used in the new iPhone Air.

Why did Apple make the chips so different?

Creating a major performance divide helps Apple clearly segment its product lineup. It provides a compelling reason for users to choose the more expensive Pro models for advanced tasks.
