Apple Begins Mass Production of Next-Generation M5 Chip

Apple has reportedly started mass production of its highly anticipated M5 chip, with devices featuring the processor potentially arriving as early as this year, according to South Korean media.

ET News reports that the M5 chip entered the packaging phase last month. Packaging is the final step in chip manufacturing, where the processor is protected and prepared for integration with other components. While TSMC handles the initial chip fabrication on silicon wafers, the packaging process is managed by OSAT (Outsourced Semiconductor Assembly and Test) companies, including Taiwan’s ASE Group, America’s Amkor, and China’s JCET. ASE was reportedly the first to begin mass production of the M5 chip, with Amkor and JCET expected to follow soon.

The initial production is focused on the base M5 model, with the more advanced M5 Pro, M5 Max, and M5 Ultra processors slated for later production. To support the high-end models, these OSAT companies are said to be expanding their facilities.

Advanced Features of the M5 Chip

The M5 series is expected to feature an enhanced ARM architecture and utilize TSMC’s cutting-edge 3-nanometer process technology. While Apple opted against using TSMC’s more advanced 2nm process—likely due to cost considerations—the M5 chips are still poised to deliver significant performance and efficiency improvements.

Notably, the high-end M5 variants will incorporate TSMC’s System on Integrated Chip (SoIC) technology, which uses a 3D chip-stacking method. This approach improves thermal management and minimizes electrical leakage compared to traditional 2D designs. Apple has reportedly deepened its collaboration with TSMC on next-generation hybrid SoIC packaging, which also incorporates thermoplastic carbon fiber composite molding technology.

What Devices Will Feature the M5 Chip?

The first device expected to debut with the M5 chip is a new iPad Pro, which Apple analyst Ming-Chi Kuo predicts will begin mass production in the second half of next year. Here’s what to expect from Apple’s lineup featuring M5 chips:

• iPad Pro: Likely to launch with M5 chips between late 2025 and early-to-mid 2026.
• MacBook Pro: Models with M5 chips are expected in late 2025.
• MacBook Air: M5-powered variants could arrive in early 2026.
• Apple Vision Pro: An updated version of the headset featuring the M5 chip is anticipated between fall 2025 and spring 2026.

Expanding Use of the M5 Chip in AI

References to the M5 chip have already surfaced in official Apple code. Reports suggest that its dual-use SoIC design will allow Apple to not only power consumer devices but also strengthen its AI server infrastructure. This move could enhance AI capabilities across Apple’s ecosystem, from cloud services to its hardware lineup.

With these advancements, the M5 chip is shaping up to be a significant leap forward for Apple’s custom silicon, offering users better performance, efficiency, and integration across devices.
