Shockingly, based on the trailing price-to-earnings multiple for both companies, AMD's shares are far more expensive. The stock has a P/E of 106, while Nvidia's is much lower at 40. So not only is Nvidia the dominant AI processor company, but its shares are also relatively cheaper, easily making Nvidia the better AI stock to own in this matchup.

Meta Platforms (NASDAQ: META) is a top social media company which routinely generates billions in profit each quarter. While it may not seem like a top AI stock to own, Meta is trying to change that impression.
