[News] Apple Reportedly Uses A18 Pro with 8GB RAM in MacBook Neo Amid TSMC Supply Constraints

Apple’s newly launched MacBook Neo features the A18 Pro chip, prompting questions about why the laptop does not use the newer A19 Pro. According to Wccftech, sources say supply constraints prevented Apple from adopting the A19 Pro, as limited supply from TSMC meant the company could not secure enough chips for the device. Apple CEO Tim Cook had previously acknowledged these constraints during the company’s earnings call, noting that Apple could have shipped more iPhone 17 Pro and iPhone 17 Pro Max units powered by the A19 Pro if supply had not weighed on sales.

If the A19 Pro had been used instead of the A18 Pro, the MacBook Neo would likely have offered higher RAM capacity, as the report notes. The A19 Pro comes with 12GB of LPDDR5X memory.

Meanwhile, Apple offers the MacBook Neo with only 8GB of RAM, with no option for higher memory capacity, as TechPowerUp indicates. The report adds that the limitation stems from the SoC’s design and Apple’s effort to keep unit costs low, restricting the company from providing more memory.

At the architectural level, the limitation is tied to the chip’s packaging design. Wccftech notes that the current 8GB cap is due to the A18 Pro’s design, in which the silicon and DRAM are integrated into a single InFO-PoP package, making memory upgrades extremely costly, if not impractical.

TrendForce forecasts Apple’s notebook shipments will grow 7.7% YoY in 2026, pushing macOS market share to 13.2%, supported by the company’s downward extension of price tiers, proactive pricing strategy, and strong supply chain control compared with peers. Shipments of the MacBook Neo alone could reach 4–5 million units, depending on consumer acceptance of its 8GB memory configuration.

MacBook Neo’s Performance Strategy and Potential Future Roadmap

Regarding performance, MacRumors highlights that the A18 Pro in the MacBook Neo delivers multi-core performance roughly on par with the M1 chip in the MacBook Air, while its single-core performance is significantly stronger—closer to that of the M3 or M4 chips. The report adds that this strong single-core performance suits the MacBook Neo’s target users, as tasks such as web browsing, document editing, and video streaming rely heavily on single-core speed.

Looking ahead, Wccftech cites analysts as saying that a successor to the MacBook Neo is already planned for a 2027 launch. As Apple moves to more advanced TSMC process nodes, supply constraints tied to older manufacturing technologies are expected to ease, potentially allowing the company to adopt more capable chips in future hardware.
