it house reported on october 2 that technology media chipwise published a blog post last month, reporting that the a18 and a18 pro chips in apple’s iphone 16 and iphone 16 pro series do not use chip binning solutions.

the media shared die shot pictures of the a18 and a18 pro chips, saying that although the layout and core elements of the two chips are relatively similar, a closer look shows that the a18 pro uses more transistors, and some of them are designed on the chip. the space occupied is much larger than that of the a18.

the media believes that judging from the die shot pictures, apple did not simply sort the chips when producing the a18 and a18 pro chips.

it home briefly introduces chip sorting, which is an important step in the semiconductor production process and is mainly used to classify the produced chips according to their performance and quality.

judging from the obvious differences in the photos, apple does appear to be designing and producing two different chips, rather than relying on chip sorting.
