Is Credo Technology a Better AI Networking Buy Than Broadcom?

Broadcom and Credo Technology are both major players in AI networking, but they differ significantly in size and growth potential. Broadcom, a tech giant with a $1.65 trillion market cap, reported AI semiconductor revenue of $16.7 billion in Q3 2026, a 221% year-over-year increase. Its forward-looking guidance for fiscal 2026 AI revenue is an astounding $58 billion, with projections of $115 billion by 2027 and $230 billion by 2028.

Broadcom's Tomahawk Ethernet switches are popular in AI data centers, catering to both processing power and data transfer needs. The company trades at a forward P/E ratio of roughly 18, offering a safe, dividend-paying investment for AI portfolios.

Credo Technology, on the other hand, is a networking specialist known for its active electric cables (AECs) and serializer/deserializer (SerDes) data converter modules. While its trailing sales are $1.6 billion, Credo's revenue more than doubled year-over-year in fiscal 2027 Q1, reaching $479 million. The company's rapid expansion into the optical market, driven by its optical digital signal processors (DSPs), silicon photonics, and innovative Zero-Flap Optics, is expected to generate over $600 million in sales this fiscal year from optical segment alone.

Broadcom also produces SerDes modules, likely collecting royalties from Credo's sales. For conservative investors, Broadcom is the clear choice due to its foundational tech stock status and strong relationships across the tech sector. However, if you're seeking explosive upside, Credo's specialized technological moat in both copper and optical connectivity, coupled with its high-growth momentum, makes it an attractive option for growth-focused portfolios.
