The A15 chip in the 13 Pro models was more expensive than the A16 chip in the 14 Pro models.

The A16's higher cost is likely due in part to the chip being manufactured based on TSMC's 4nanometer process.

The Geekbench results show that the A16 chip is 15% to 17% faster than the A15 chip. The A16 chip is only found in the iPhone 14 Pro and the iPhone 14 Pro Max, while the A15 chip is found in the other two models.

In collaboration with Fomalhaut Techno Solutions, a Japanese research firm specialized in reverse engineering and bill-of-material analysis, Nikkei found that production costs have increased about 20% across the iPhone 14, iPhone 14 Pro, and iPhone 14 Pro Max compared to the equivalent previous- generation models.

The higher production costs mean that the company's profit margins have probably shrunk, but prices did increase in key markets like the U.K.
