Nvidia is unstoppable--until somebody invents a better AI chip

Nvidia stock is soaring, up more than 14% in after-hours trading, beating Wall Street's expectations for its first quarter. The graphics processing unit (GPU) company announced its first quarter earnings today with revenue of $1.94 billion, a 48% gain year over year. While gaming drives most of the company's sales, its largest area of growth over the past year was selling GPUs that power the artificial intelligence and graphics processing in datacenters. That sector of business saw 186% growth year over year, just a dip below last quarter's 205% growth. Nvidia has built itself into a leader in this space, selling enterprise GPUs to Google, Microsoft, Amazon, IBM, Tencent, and Baidu.
