Last month, Apple unveiled the innovative A18 and A18 Pro chipsets for its new iPhone 16 series. These next-gen 3nm processors promise a slew of enhancements over the previous A17 Pro, despite maintaining the same 6-core CPU architecture and differing by only one GPU core. Yet, a fresh die shot comparison sheds light on how even this minor variation can lead to significant reconfigurations of various clusters within the chip.
Manufactured using TSMC’s advanced InFO-POP (Integrated Fan-Out Package-on-Package) packaging technology, the A18 and A18 Pro boast reduced die sizes and enhanced thermal and electrical performance. This cutting-edge packaging technique stacks DRAM directly on the chip die and incorporates high-density redistribution layers along with Through InFO Via technologies. As a result, Apple gains greater flexibility since the DRAM package can be easily swapped or upgraded without impacting the overall design.
A meticulous analysis by Chipwise has provided new insights into these processors. On the surface, the A18 and A18 Pro appear nearly identical in their technical specs. However, microscopic examination reveals notable differences. One key advantage of the InFO-POP technology is its ability to optimize both the thermal management and electrical performance of the chip, which are critical for maintaining the efficiency and durability of the iPhone 16 series.
In the die shot comparisons, attempts have been made to locate the additional GPU core on the A18 Pro. Preliminary findings suggest that this extra core is situated at the upper left part of the die. However, without proper labeling of the CPU and GPU clusters and the Neural Engine, a more detailed analysis is still needed to fully understand these configurations.
For tech enthusiasts and experts with keen observational skills, this die shot presents an intriguing puzzle. Can you identify the various clusters within the chip configuration? Your insights could shed more light on these cutting-edge SoCs. Feel free to share your observations and join the discussion.
