Core Viewpoint - Nvidia and Alphabet are major players in the artificial intelligence sector, with Nvidia primarily providing GPUs and Alphabet developing its own TPU, which serves a specific niche in AI computing [1][3][4]. Group 1: Company Overview - Nvidia specializes in graphics processing units (GPUs) that are widely used for AI, cryptocurrency mining, drug discovery, engineering simulations, and gaming graphics [3]. - Alphabet has developed the Tensor Processing Unit (TPU) over the past decade in collaboration with Broadcom, positioning itself as a competitor in the AI computing space [4]. Group 2: Market Dynamics - While Nvidia's GPUs are versatile, they may not be fully utilized for specific workloads, leading to inefficiencies for clients [3]. - Alphabet's TPUs are available exclusively through Google Cloud, which may limit clients' flexibility in switching providers, thus encouraging a balanced use of both Nvidia's GPUs and Alphabet's TPUs [5].
