Two chip designers are quietly powering the artificial intelligence boom — and investors are increasingly asking which one deserves a bigger slice of their portfolio.
Broadcom and Marvell Technology are both key players in what's called AI infrastructure: the custom processors and networking components that make large-scale AI systems run. According to reporting aggregated by Yahoo Finance and The Motley Fool, Broadcom currently dominates the custom AI chip market, while Marvell is described as making "solid gains" in the same space.
Both companies occupy a different niche than the headline-grabbing GPU makers. Rather than building general-purpose chips, they specialize in custom AI processors — silicon tailored to the specific needs of large cloud customers — along with the high-speed networking hardware that connects all those chips together inside data centers.
Broadcom trades on the Nasdaq under the ticker AVGO, while Marvell trades as MRVL. Both stocks have shown notable movement as investor appetite for AI infrastructure plays has grown.
The comparison matters because custom chip design is becoming a serious alternative to buying off-the-shelf processors — major cloud companies are increasingly commissioning their own silicon rather than relying solely on merchant chip suppliers. That trend puts both Broadcom and Marvell in a structurally advantageous position, even as they compete for the same customers.
For everyday investors, the Broadcom-vs-Marvell question is really a proxy for a bigger bet: which part of the AI supply chain — raw compute power or the custom and networking layer beneath it — will capture the most value as AI infrastructure spending accelerates.
