Rigetti Computing’s stock has experienced significant volatility since its public debut three years ago. Despite a recent rebound, the company faces challenges such as high enterprise valuation relative to projected sales. In contrast, Nvidia, a leader in AI chips, has shown robust growth and holds a near-monopoly in the data center GPU market. A $50,000 investment in Nvidia 10 years ago would be worth over $10 million today. Nvidia’s GPUs are preferred for complex machine learning tasks over CPUs, making it a key player in the AI sector. With reasonable valuations and strong growth projections, Nvidia could be a more stable investment opportunity compared to Rigetti. — news from The Motley Fool
