Broadcom vs. AMD: Which AI Chip Stock Will Outperform in 2026?

Core Viewpoint - The competition between Broadcom and AMD to challenge Nvidia's dominance in the AI infrastructure market is intensifying, with both companies showing strong stock performance in 2025, particularly AMD with a year-to-date increase of over 70% compared to Broadcom's approximately 45% gain [1]. Summary by Company AMD - AMD is the second-largest player in the GPU market, focusing on the inference segment where cost-per-inference is crucial, and it has a competitive edge against Nvidia's CUDA software [3]. - Microsoft is developing a toolkit to convert CUDA code to AMD's ROCm, enhancing the use of AMD GPUs for inference, and AMD has partnered with OpenAI to deploy 6 gigawatts of GPUs, starting with 1 gigawatt next year, with OpenAI also acquiring a stake in AMD [4]. - In addition to GPUs, AMD is a leading provider of CPUs for computers and data centers, a rapidly growing market where it is gaining market share [5]. Broadcom - Broadcom approaches the AI chip market by designing custom AI ASICs, which are preprogrammed chips optimized for specific tasks, offering better performance and energy efficiency compared to traditional GPUs [6]. - The company has collaborated with Alphabet to develop Tensor Processing Units (TPUs), which have attracted other major data center operators as customers, with potential revenue from three key customers projected to exceed $60 billion by fiscal year 2027, and a $21 billion order from Anthropic for TPUs [7]. - Both AMD and Broadcom are trading at similar valuations, indicating a competitive landscape [8].
