<div id="readability-page-1">Has the excitement surrounding artificial intelligence (AI) stocks cooled off? Many top AI stocks are down this year, including Advanced Micro Devices (AMD 1.31%), better known as just AMD, and Nvidia (NVDA 0.28%). They have both declined around 15% thus far in 2025, which is worse than S&amp;P 500's more modest drop of 4%. There's still massive potential for AI to revolutionize businesses and entire industries, but investors have been starting to scale back their positions in AI. If, however, you're looking at the long haul, then now can be a great time to add a top AI stock to your portfolio. Which of these two chip stocks is the better option right now: AMD or Nvidia? <div><img src="https://imageproxy.pbkrs.com/https://g.foolcdn.com/image//query-b3A9cmVzaXplJnVybD1odHRwczovL2cuZm9vbGNkbi5jb20vZWRpdG9yaWFsL2ltYWdlcy84MTcwODAvY2VsbC1waG9uZS1hcHBsaWNhdGlvbi13YWl0aW5nLWZvci1hLXZvaWNlLXByb21wdC1mcm9tLWEtdXNlci5qcGcmdz03MDA?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="700" height="466" original-src="https://imageproxy.pbkrs.com/https://g.foolcdn.com/image//query-b3A9cmVzaXplJnVybD1odHRwczovL2cuZm9vbGNkbi5jb20vZWRpdG9yaWFsL2ltYWdlcy84MTcwODAvY2VsbC1waG9uZS1hcHBsaWNhdGlvbi13YWl0aW5nLWZvci1hLXZvaWNlLXByb21wdC1mcm9tLWEtdXNlci5qcGcmdz03MDA"/>Image source: Getty Images. </div> <h2>Comparing their valuations</h2> Nvidia is one of the most valuable companies in the world, with a market cap of $2.8 trillion. That has come down a bit amid its recent decline (last year it was well above $3 trillion), but it's still close to 17 times the value of AMD, which has a market cap of around $165 billion. While AMD isn't a small company by any means, when compared to Nvidia, it looks tiny. While you might think that Nvidia is the pricier of the two stocks given its massive valuation, based on earnings, it's actually the cheaper stock. <img src="https://imageproxy.pbkrs.com/https://media.ycharts.com/charts/51a9fefab28d5f2fd91c713c07f259ae.png?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="720" height="456" original-src="https://imageproxy.pbkrs.com/https://media.ycharts.com/charts/51a9fefab28d5f2fd91c713c07f259ae.png"/> NVDA PE Ratio data by YCharts Last year, AMD reported $1.6 billion in profit, while Nvidia, which has a fiscal year that ends in January, has generated an incredible $72.9 billion in earnings over its last four quarters. Not only has its business been experiencing explosive growth, but Nvidia's bottom line has been growing quickly as its profit margin has averaged 56%. That has enabled its price-to-earnings (P/E) multiple to remain relatively low. By comparison, AMD's profit margin is just 6%. And with a more modest bottom line, it's the more expensive stock of the two when taking into account its earnings per share. <h2>Which AI stock may have the most upside?</h2> Both stocks have been struggling this year but when looking at the past 12 months, Nvidia is still up around 29% while AMD has fallen by 33%. A case could be made that AMD may be due for a rally, especially if its AI chips prove to offer formidable competition to Nvidia's high-priced options. AMD CEO Lisa Su previously forecast that the company could generate &#34;tens of billions of dollars in annual revenue&#34; in the near future due to its AI chips. If AMD can generate that much growth, it can certainly help attract more investors and propel the stock to a much higher valuation. Thus far, it's lagged behind Nvidia in a big way. Last year, AMD's sales rose by 14%, while Nvidia more than doubled its revenue during its most recent fiscal year. But what also matters are AMD's margins, which need improvement. Otherwise, its P/E multiple may not come down significantly even if its growth rate accelerates. And a high premium could deter investors. Nvidia is in pole position today, dominating the market and still innovating and coming up with new AI chips. AMD has to prove that it can put up some formidable competition. And until it does, that could limit its upside both in the near term and the long term. <h2>Nvidia is the stock I'd go with today</h2> AMD can potentially be a great long-term investment but it has a lot of question marks around its operations; it's far from a slam-dunk buy at this stage and it comes with some risk. Not only does it need to show that its chips can provide real competition to Nvidia, but the company also has to improve upon its single-digit profit margin. With much stronger financials, a more attractive valuation, and a more dominant position in the market, Nvidia is the better AI stock to buy today. </div>

NVDA

AMD and Nvidia, two leading AI stocks, have both seen declines of around 15% in 2025, worse than the S&P 500's 4% drop. Nvidia, with a market cap of $2.8 trillion, has reported $72.9 billion in earnings, while AMD's profit margin is only 6%. Despite AMD's potential for growth in AI, Nvidia's stronger financials and market dominance make it the preferred investment choice currently. AMD needs to improve its operations and profit margins to compete effectively with Nvidia.

- The excitement around AI stocks has diminished, with both Advanced Micro Devices (AMD) and Nvidia experiencing declines of about 15% in 2025, compared to a 4% drop in the S&P 500.  
- Nvidia, with a market cap of $2.8 trillion and a profit margin of 56%, is currently viewed as the more attractive investment despite its higher valuation, while AMD's profit margin stands at just 6%.  
- Although AMD has potential for growth, it faces significant challenges in competing with Nvidia, making Nvidia the preferred choice for investors at this time.
