A19 vs A19 Pro Chip Benchmark Comparison

Introduction

Apple has equipped the iPhone 17 series with the new generation A19 and A19 Pro chips, both using TSMC’s latest third-generation 3nm process (N3P). Although the process is the same, there are still many key differences between the A19 chip series.

Cache Comparison

L2 Cache Configuration

• A19 Pro: 22MB total L2 cache (including large and small cores)
• A19: 12MB total L2 cache

System Level Cache (SLC)

• A19 Pro: 32MB cache
• A19: 12MB cache

The A19 Pro’s SLC is nearly three times that of the A19, which is regarded as the key difference in their actual performance.

GPU Specifications

With the GPU frequency at 1,620MHz, Apple has made differentiated configurations:

A19 Pro (iPhone 17 Pro / Pro Max)

• Execution Units (EUs): 96 units
• Arithmetic Logic Units (ALUs): 768 units

A19 (iPhone 17)

• Execution Units (EUs): 80 units
• Arithmetic Logic Units (ALUs): 640 units

Conclusion

The significant differences in cache size and GPU configuration between A19 and A19 Pro chips result in noticeable performance variations, particularly in graphics-intensive applications and multitasking scenarios.
