Apple has adopted TSMC’s latest 3nm process for both the A19 Pro and A19, but this advanced lithography does not mean that these chips are identical. In fact, Apple ensured that its current-generation SoCs appear as two distinct classes of silicon. However, the company did not highlight these differences at the iPhone 17 event to avoid undermining device capabilities. Fortunately, a detailed table has been shared, revealing numerous details that you might not have known existed.
### The Binned Version of A19 Pro
The binned version of the A19 Pro shares fewer similarities with the A19. Both share the same six-core CPU and identical clock speeds, so expect similar single-core and multi-core compute performance between them. However, key differences include:
– **L2 Cache**: The A19 Pro has a larger L2 cache, totaling 22MB for its big and small cores combined, whereas the A19 sports only 12MB.
– **Single Level Cache (SLC)**: Apple prioritized SLC in the A19 Pro, which is 32MB compared to the A19’s 12MB. This change should significantly impact performance differences.
### Graphics Processing Unit
The A19 Pro has a more powerful GPU configuration:
– **A19 Pro**: Features 5-core GPU with 96 Execution Units (EUs) and 768 Arithmetic Logic Units (ALUs).
– **Binned A19 Pro**: Has fewer EUs at 80, but the same number of ALUs as the standard A19.
### Memory Specifications
– **Memory Frequency and Bandwidth**: The faster A19 Pro with 12GB LPDDR5X RAM operates at 9,600MT/s, resulting in a bandwidth of 75.80GB/s. In contrast, the binned variant’s 8,533MT/s delivers a slower 68.26GB/s, matching the A19 but limited to 8GB.
### Neural Processing Unit
Both the A19 Pro and A19 feature the same 16-core Neural Engine with no changes across the three chipsets. Unfortunately, die size details were not provided, but more information is expected in the coming weeks.
