Tesla’s Bold AI Chip Manufacturing Strategy
Elon Musk has revealed significant details about Tesla’s semiconductor roadmap, confirming that the company‘s next-generation AI5 chips will be manufactured by both Samsung and TSMC at their respective U.S. facilities. During Tesla’s third-quarter earnings call, Musk outlined an ambitious production strategy aimed at creating what he termed “excess production” of the advanced processors.

The dual-foundry approach represents a sophisticated manufacturing strategy that leverages both Samsung’s Texas facility and TSMC’s Arizona operations. This marks a significant evolution from earlier announcements, where Musk had indicated TSMC would produce AI5 chips while Samsung would handle the subsequent AI6 generation., according to industry developments
Strategic Oversupply: Beyond Vehicles and Robots
Tesla’s explicit goal of creating an AI5 chip oversupply reveals a multifaceted strategy that extends beyond the company‘s core automotive and robotics applications. Musk emphasized that any surplus chips not utilized in Tesla vehicles or Optimus robots would be redirected to power the company’s expanding data center operations.
“Our explicit goal is to have an oversupply of AI5 chips,” Musk told investors, highlighting how this approach provides operational flexibility across Tesla’s diverse technology portfolio. The strategy ensures that manufacturing capacity can be dynamically allocated between Tesla’s automotive, robotics, and AI infrastructure needs.
Nvidia Relationship: Complementary Rather Than Competitive
Despite Tesla’s significant investments in custom silicon, Musk took care to clarify the company‘s ongoing relationship with Nvidia. “We’re not about to replace Nvidia, to be clear, but we do use both in combination,” Musk stated, emphasizing the complementary nature of the two companies’ technologies.
Tesla continues to rely on Nvidia’s industry-leading GPUs for training its AI models, while deploying its custom-designed chips for inference and specialized applications. The company announced it now possesses computing capacity equivalent to 81,000 of Nvidia’s H100 chips, underscoring the massive scale of its AI infrastructure.
Technical Specifications and Manufacturing Details
The AI5 chip represents the latest iteration of Tesla’s Autopilot hardware system, designed to process the complex sensor data required for autonomous driving functionality. Musk revealed that the chip would utilize a “half reticle” design, making it approximately half the size of competing “full reticle” AI chips from industry leaders like Nvidia and AMD.
This manufacturing approach offers several advantages:
- Enhanced yield rates through smaller die sizes
- Manufacturing flexibility across multiple foundries
- Cost optimization through competitive bidding between suppliers
Historical Context and Leadership Changes
Tesla’s chip development program has evolved significantly since the company transitioned from Nvidia’s Drive chips to its own custom processors in 2019. The recent departure of former Apple engineer Peter Bannon, who previously led Tesla’s chip design efforts and spearheaded the Dojo supercomputer project, adds an interesting dimension to the company’s semiconductor narrative.
The AI5 chip was first announced in 2024 during Tesla’s shareholder meeting, building upon years of internal semiconductor development. The substantial $16.5 billion chip contract with Samsung, initially announced with an unnamed client in July, was later confirmed by Musk to be for Tesla’s semiconductor needs., as earlier coverage
Tesla’s sophisticated approach to semiconductor strategy demonstrates how automotive companies are increasingly becoming technology companies, with chip design and manufacturing becoming core competencies in the age of electric and autonomous vehicles.
