Broadcom vs. AMD: Which AI Chip Stock Has the Better Risk-Reward?

Tech behemoths Broadcom Inc AVGO and Advanced Micro Devices, Inc. AMD have benefited immensely from strong artificial intelligence (AI)-driven growth, as reflected in their latest quarterly results. However, the two companies differ in their growth prospects, competitive positioning and valuation. So, which stock offers the better risk-reward opportunity for investors? 

Reasons to Be Bullish on Broadcom 

As per Broadcom’s June 3 press release, the company’s AI semiconductor business posted exceptional growth. In the fiscal second quarter of 2026, the company’s AI semiconductor revenues reached $10.8 billion, up 143% year over year. The momentum is expected to continue into the next quarter. Broadcom projects AI semiconductor revenues of $16 billion in the fiscal third quarter of 2026, representing more than 200% year-over-year growth (read more: Broadcom Q2 Earnings Call Spotlights AI Demand Surge).

Consolidated revenues for the fiscal third quarter are expected to reach $29.4 billion, up 84% year over year. This follows record consolidated revenues of $22.2 billion in the fiscal second quarter, representing a 48% year-over-year increase.  

Broadcom is also maintaining strong profitability while delivering rapid AI-driven revenue growth. In the fiscal second quarter, Broadcom generated $15.2 billion in adjusted EBITDA, which resulted in an adjusted EBITDA margin of 69%. Similarly, the company expects the EBITDA margin to remain around 68% in the fiscal third quarter.   

Reasons to Be Bullish on AMD 

AMD reported $11.5 billion in revenues in the second quarter of 2026, up 50% year over year and 13% sequentially, citing the company’s Aug. 4 press release. Data Center revenues were particularly strong, more than doubling from the prior-year period (read more: Advanced Micro Q2 Earnings: How Key Metrics Compare to Wall Street Estimates).  

Data Center revenues are expected to accelerate in the second half of the year. At the same time, overall revenues are expected to reach $13 billion, plus or minus $300 million, in the third quarter of 2026. From the midpoint, that would result in 41% year-over-year growth and a 13% sequential rise. 

Rising demand for AMD’s EPYC server processors supported the company’s growth outlook. Meanwhile, AMD’s Instinct accelerators are witnessing rapid growth, while the Helios platform has entered its initial production ramp. The company is also delivering strong revenue growth along with improving margins. For the fiscal third quarter, AMD expects a healthy non-GAAP gross margin of 56%. 

Broadcom or AMD: Which AI Chip Stock Offers Better Risk-Reward? 

Strong revenue growth and a healthy adjusted EBITDA margin make a compelling case for further upside in Broadcom’s share price. An upbeat revenue outlook suggests that Broadcom is well-positioned to enter a multi-year growth cycle rather than a temporary surge. As demand for Broadcom’s custom AI accelerators and AI networking solutions increases, growth should continue. 

Similarly, accelerating Data Center growth, strong demand for EPYC processors, and the Instinct accelerators could support continued share-price appreciation for AMD. Expanding margins, along with the initial ramp-up of the Helios platform, could further boost earnings and shareholder returns.  

However, Broadcom has more diversified AI exposure through its infrastructure software, custom accelerators and networking. By contrast, AMD continues to face challenges in gaining market share from NVIDIA Corporation NVDA in the AI ecosystem.  

Additionally, AMD trades at a forward price/earnings ratio of 63.64, significantly higher than Broadcom’s 31.66. This elevated multiple indicates that a substantial portion of AMD’s expected growth is already reflected in its valuation, leaving it more vulnerable to a downturn if earnings growth fails to meet expectations. In contrast, Broadcom trades at a lower earnings multiple, offering investors a more favorable balance between growth potential and valuation.

Overall, Broadcom offers a better risk-reward profile, supported by a strong growth outlook and lower valuation. In contrast, AMD’s higher valuation and competitive challenges make its upside more dependent on strong execution. Both Broadcom and AMD currently carry a Zacks Rank #3 (Hold).

Beyond Nvidia: AI's Second Wave Is Here

The AI revolution has already minted millionaires. But the stocks everyone knows about aren't likely to keep delivering the biggest profits. AI’s second wave is moving from infrastructure to implementation and these companies are at the forefront of this transition, positioned to become what Amazon and Google were to the internet era.
