Highlights:

• Apple is developing its own AI server chip, codenamed “Baltra,” for cloud infrastructure
• Built using advanced 3nm technology from TSMC
• Move aims to reduce reliance on NVIDIA and strengthen Apple’s AI ecosystem

Apple is quietly building a major foundation for its AI future with a new self-designed server chip known internally as “Baltra.” This chip is expected to power the company’s internal cloud infrastructure, focusing on secure data processing and backend AI workloads. It marks a major shift as Apple expands beyond consumer hardware into large-scale AI computing.

The Baltra chip is likely to be manufactured by TSMC using its second-generation 3nm (N3E) process. This technology is designed to deliver improved performance and efficiency compared to earlier nodes. Apple is also investing heavily in TSMC’s advanced SoIC (System on Integrated Chips) packaging, which enables vertical stacking of multiple chip components for better speed and power efficiency.

Reports suggest Baltra will use a chiplet-based architecture, allowing different specialized chips to work together in one package. This design improves scalability and lets Apple optimize AI workloads more effectively. The company is also working with partners on interconnect technologies while gradually aiming to bring more design capabilities in-house.

To support its AI push, Apple has reportedly reserved significant production capacity at TSMC for the coming years. A large portion of this is expected to be allocated to AI server chips like Baltra, signaling serious long-term investment.

Overall, this move highlights Apple’s plan to control its entire AI stack, from silicon and packaging to cloud infrastructure, while reducing dependence on external chip providers and competing more directly in the AI hardware space.
