Is it actually a different die though? The A18 and A18 Pro are so close in specs, with the same 6 CPU cores, same 16 NPU cores and only 5 vs. 6 GPU cores that I would guess that they are the very same die just with one GPU cluster and USB3 switched off in the non-Pro version.
- Kirby64 2y agoOn the 15 series it was since they used different chip generations. No idea on the new 16 series, we’ll have to wait for die shots from teardown groups.

- dagmx 2y agoIn the presentation they said they’re separate dies with different features available on the Pro, that aren’t on the base SoC.
- brookst 2y agoYes, different dies. The Pro also has a more advanced NPU and massively more IO bandwidth to process 4K120 video.
- Aaargh20318 2y agoThey mentioned the Pro also has a larger CPU cache.
- nabla9 2y agoA18 Pro is also faster. Typically the speed and 5 vs 6 core difference would use the same die and selecting Pro chips during testing. Chips that tolerate heat better become pro-model chips. The rumor was that they are different dies. It seems strange because both are made with the same 2nd generation 3nm architecture.
