Samsung wins Tesla's AI5 chip for 2nm production and develops its own 'Gauss' AI PC chip

Samsung landed a marquee foundry win: it disclosed its first concrete timeline for producing Tesla's AI5 chip on its 2nm process, having completed development of the automotive-grade 2nm chip. That's a significant validation of Samsung's advanced-node foundry against TSMC, in a segment — self-driving/automotive AI silicon — where reliability requirements are extreme.

Separately, Samsung's System LSI division is developing its own AI PC chip, codenamed 'Gauss,' built on a 4nm process and targeting mass production next year. It marks Samsung's re-entry into the PC chip market after roughly a decade and is aimed at expanding its AI-semiconductor business into AI PCs and physical AI (robotics). Prototypes are reportedly being supplied to global PC manufacturers for performance verification, putting Samsung on a collision course with Intel and Qualcomm in the emerging AI-PC category.

The strategic backdrop is Samsung's blockbuster quarter — preliminary Q2 2026 operating profit of ~89.4 trillion won (~$58B), roughly 20x higher year-over-year, driven by AI-chip demand. CEO Jay Y. Roh outlined an entry into the 'agentic age' with custom silicon, smart-glasses work with Google, and custom AI-chip talks with Anthropic. Samsung also teased a next Galaxy Watch centered on an AI-powered Health Companion.

The competitive read: Samsung is attacking the AI hardware stack from multiple angles — foundry (Tesla), its own PC silicon (Gauss), and devices (Galaxy Watch AI). The caveat is that Gauss re-enters a crowded AI-PC market dominated by Qualcomm's Snapdragon and Intel, and Samsung's past PC-chip efforts fizzled. Watch whether prototypes convert into design wins.
