The difference in performance between the current iPhone 13 series is not that big, the standard model is equipped with a 4-core GPU, while the Pro model is equipped with a 5-core GPU. Both the standard models come with 4GB of memory, while the Pro models come with 6GB of memory, but both are LPDDR4X spec.
The iPhone 14 and iPhone 14 Max are expected to use the A15 chip with a 5-core GPU and will be equipped with 6GB of LPDDR4X memory, so it is still an upgrade compared to the current model.
So what about the iPhone 15 Pro and iPhone 15 Pro Max? Foreign technology media MacWorld tries to answer this question. It is worth noting that the new A16 chip will be based on TSMC’s N4P node, which is more advanced than the N5P node used by the A15, but the upgrade is not particularly large.
The number of transistors in the new A16 chip is expected to be upgraded from the existing 15 billion to 18-20 billion, and will switch to the ARMv9 instruction set. Through the Cortex-A715 and X3 core, it is expected to provide more powerful performance. It is estimated that the A16 chip can improve the performance of the CPU by 15%, and Apple may retain the core configuration of 2 large and 4 small.
In addition, according to DigiTimes reports, the iPhone 14 Pro and iPhone 14 Pro Max will use LPDDR5 memory, with 50% greater transmission bandwidth than LPDDR4X, and more energy-efficient startup. Both models will likely remain at 6GB.
In terms of GPU, it is estimated that the A16 chip will still adopt a 5-core design to avoid the chip being too large, but it does not rule out the possibility of upgrading to 6-core. According to previous news, GPU performance estimates can be improved by 25-30%.
Apple may also handle higher resolutions by improving ISP and machine learning hardware. The main camera of the iPhone 14 Pro series will be upgraded to 48 million and support 8K video recording. Abandoning the resolution limit of Cinematic Mode may also be upgraded from 1080P to 4K,
