Best Artificial Intelligence (AI) Stock: AMD, Nvidia, or Broadcom

Key Points

If you asked me at the start of the year how I would rank Advanced Micro Devices (NASDAQ: AMD), Broadcom (NASDAQ: AVGO), and Nvidia (NASDAQ: NVDA) in terms of potential stock performance, I would have put Nvidia at the top, Broadcom in the middle, and AMD in last place. So far in 2026, my projection that Broadcom would be in the middle has panned out, but AMD has been a massive winner while Nvidia has been a loser.

There’s still a lot of time left in 2026, but which one of these three artificial intelligence (AI)-related stocks is the best buy now?

Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a “Double Down” signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same “Total Conviction” signal is flashing for a company 1/100th the size of Nvidia. Continue »

Let’s take a look at this trio and rerank them for the rest of 2026 and into 2027.

AMD and Nvidia are competing in the same field

All three of these stocks are being heavily spurred on by massive AI spending. AMD and Nvidia approach this problem from the same perspective, as each offers graphics processing units (GPUs) that excel in computing scenarios with variable, complex workloads. However, Nvidia’s products have downright dominated the field to date, and it holds a commanding lead in the data center space.

Broadcom is taking a completely different approach. Instead of a broad-purpose computing unit like a GPU, it has partnered directly with a handful of AI hyperscalers to design a custom AI chip tailored to the workloads each firm sees. This creates a chip that often offers better cost-performance than GPU-based computing, driving its rising popularity.

Broadcom expects major growth next year as new clients launch their custom AI chips. Currently, Broadcom’s major customer is Alphabet, with its Tensor Processing Units (TPUs). However, Broadcom is also making custom AI chips for Meta Platforms, Anthropic, and OpenAI, and production for those chips is scheduled to ramp up late this year and into next.

So, which of these is the best horse to back from a business approach? I’m still bearish on AMD, as it has a major uphill battle to win space in data centers when so many ecosystems have already been developed around Nvidia’s. Between Nvidia and Broadcom, it’s tough because many companies will stick with GPU-based training for its flexibility. Still, custom AI chips will likely become quite popular over the next few years as AI hyperscalers look to optimize their spending. As a result, I’m giving this one to Nvidia and Broadcom as a tie.

Winners: Nvidia and Broadcom

Nvidia is still dominating the growth game

From a growth standpoint, Nvidia still stands alone at the top, growing far faster than the other two.

Looking ahead, the market still expects Nvidia to maintain its lead for the full fiscal year, though Broadcom is starting to close the gap.

AMD is still well behind Nvidia, and while I think Broadcom is still a strong pick, Nvidia will likely retain its rapid-growth title for some time.

Winner: Nvidia

AMD’s stock is outrageously expensive

Lastly, let’s look at valuation. Because all three of these stocks are rapidly growing, the best way to value them is by using earnings projections. For the current fiscal year, AMD’s stock is far more expensive than either Broadcom’s or Nvidia’s. Furthermore, Broadcom is also more than 50% more expensive than Nvidia’s.

If we use next fiscal year’s projections, the trend remains the same: Nvidia’s stock looks dirt cheap compared to the other two.

Clearly, Nvidia is the winner here as well.

Winner: Nvidia

Investors should sell AMD shares for Nvidia shares

I think the biggest takeaway here is that AMD’s 2026 rally has likely gotten ahead of itself, and investors are discounting Nvidia far too much, as its display is being far more successful than AMD’s. Broadcom is still a solid stock pick with strong growth head, but it just isn’t as good a deal as Nvidia right now.
