Broadcom vs. TSMC: Which AI Chip Stock Is the Better Buy?

Custom AI processors are gaining ground as large technology companies look beyond Nvidia’s graphics chips and toward hardware built for specific models and workloads. Alphabet GOOGL has pushed its Tensor Processing Unit for Gemini, while OpenAI and Anthropic are also leaning into specialized silicon.

Broadcom AVGO is emerging as a central supplier in that shift. The chip designer has worked on Google’s TPU across seven generations and has a multiyear partnership with OpenAI to help develop 10 gigawatts of custom AI accelerators. The company also expects AI chip revenue to reach $100 billion by the end of 2027.

Broadcom said its 2025 net revenue rose 24% to $63.8 billion, while diluted earnings per share climbed 40% to $6.82. The shares fell nearly 3%.
