Yesterday, Apple announced its newest low-cost MacBook Neo, starting at $599 in the United States, or about $499 for education and students. Some online criticism emerged regarding Apple’s decision to offer a laptop with only 8 GB of RAM in 2026, with no options for higher RAM capacity. However, this 8 GB of RAM is a design choice Apple made at TSMC’s packaging facilities for the A18 Pro chip. Inside the MacBook Neo, Apple decided to reuse the iPhone 16 Pro’s chip, which comes from TSMC with 8 GB of LPDDR5X memory. This memory is attached directly above the A18 Pro SoC using Integrated Fan-Out Package on Package (InFO-PoP), creating a 3D wafer-level fan-out package. This package is designed to hold memory directly above the SoC die, resulting in a smaller PCB design without the LPDDR5X module taking up over 100 mm² of PCB area.
Therefore, Apple’s MacBook Neo configurations are limited to what the A18 Pro SoC is originally packaged with. These are 8 GB LPDDR5X modules that are shipped directly to TSMC for integration into the InFO-PoP package, which is later shipped back to Apple for integration into these new MacBook Neo laptops. While offering 8 GB laptops in modern times might seem controversial, the design choices behind the SoC and the goal of keeping unit costs low are what limit Apple from providing more memory capacity. Finally, these SoCs use Unix-based macOS, which is optimized for good memory management at this capacity, ensuring that users can still have a satisfactory experience.
