The artificial intelligence boom has transformed the technology landscape, leaving investors to choose between the companies that design powerful chips and the ones that provide the machinery to build them. Should you buy Applied Materials (AMAT -7.78%) or Advanced Micro Devices (AMD +0.52%)?
Applied Materials is a titan in the equipment space, selling the tools required to fabricate complex semiconductors. Advanced Micro Devices focuses on the architecture itself, designing high-performance processors for servers and PCs. Both companies sit at the heart of the digital economy, but they offer different paths to growth for investors.

Key Financial Metrics
The case for Applied Materials
Applied Materials provides the specialized machinery, software, and services used to manufacture chips and displays. Its global reach includes a massive footprint in China, Taiwan, and Korea, where it serves the world's largest chipmakers. In October 2026, the company expanded its partnership with Intel (INTC +0.75%) to focus on hardware for the semiconductor stocks market. However, its customer base is highly concentrated, with two major clients accounting for roughly 19% and 15% of revenue in fiscal 2025. Customer concentration like this adds a layer of risk to the business.
In FY 2025, revenue reached nearly $28.4 billion, representing growth of approximately 4.4% compared to the prior year. The company reported net income of close to $7.0 billion for the same period. This resulted in a net margin of roughly 24.7%, which measures the percentage of revenue remaining as profit after all expenses are paid.
As of its October 2025 balance sheet, the debt-to-equity ratio was roughly 0.3x. This metric compares total debt to the value of shareholder equity, with lower numbers suggesting a conservative financial structure. The current ratio, which measures a company's ability to cover short-term debts with assets that can be converted to cash quickly, was approximately 2.6x. Free cash flow for the year reached nearly $5.7 billion, representing the cash a business generates after accounting for the costs required to maintain or expand its physical assets.
The case for Advanced Micro Devices
Advanced Micro Devices designs high-performance computing and graphics products for data centers, gaming, and PCs. In October 2025, the company secured a multiyear strategic partnership with OpenAI to deploy Instinct GPUs at significant scale. It also maintains ongoing collaborations with Sony and Microsoft (MSFT +1.10%) for semi-custom chips used in game consoles. The company relies on a small number of customers for a substantial portion of its revenue, including hyperscale data centers and original equipment manufacturers.
In FY 2025, revenue surged to approximately $34.6 billion, a significant increase of roughly 34.3% over the previous year. Net income for the period reached close to $4.3 billion. The company achieved a net margin of nearly 12.5%, indicating how much profit it generates from its total sales.
As of its December 2025 balance sheet, the debt-to-equity ratio was approximately 0.1x. The current ratio is nearly 2.9x, suggesting the company maintains a robust cushion to meet its immediate financial obligations. Free cash flow for the fiscal year reached close to $6.7 billion. Note that stock-based compensation represented roughly 21.2% of operating cash flow, which inflates reported cash generation since SBC is a non-cash expense added back in the cash flow statement.
Risk profile comparison
Applied Materials faces exposure to evolving export controls, particularly regarding semiconductor technology sales to China, which require complex and costly license acquisitions. High customer concentration increases volatility if major clients reduce spending or face liquidity issues. The semiconductor industry is also highly cyclical and remains sensitive to broader economic shifts. Furthermore, the company faces a $252 million settlement for export violations involving Semiconductor Manufacturing International Corp.
Advanced Micro Devices faces intense competition from established players like Intel and Nvidia (NVDA +0.38%). It relies heavily on third-party manufacturers, primarily Taiwan Semiconductor Manufacturing Company (TSM -0.22%), for wafer fabrication. Export restrictions on advanced semiconductor products to China have necessitated significant inventory charges and threaten to limit future market access. Security vulnerabilities in its hardware products could also result in reputational damage or costly remediation efforts.
Valuation comparison
Applied Materials trades at a lower multiple of future earnings estimates than its rival, potentially appealing to those looking for a more established valuation. The Forward P/E ratio compares the current stock price to future earnings estimates, while the P/S ratio measures the market value of the company relative to its sales over the past twelve months.
| Metric | Applied Materials | Advanced Micro Devices |
|---|---|---|
| Forward P/E | 39.6x | 79.6x |
| P/S ratio | 13.1x | 24.0x |

Which stock would I buy in 2026?
I'd go with AMD, and honestly it is not a close call right now. In Q2 2026, AMD's data center revenue more than doubled year over year, its partnership with Anthropic signals demand that stretches well beyond the current quarter, and the company has posted six consecutive quarters of above-30% growth. AMD is cementing its position as the primary alternative to Nvidia in the AI chip market, and that is a powerful place to be.
Applied Materials is a well-run business that keeps benefiting as chip complexity grows. In its most recent quarter, AI-driven demand for advanced semiconductor equipment kept orders healthy and the outlook was positive. For investors who want diversified exposure to the chip manufacturing build-out without betting on any single end market, it is a solid choice.
But there is a difference between benefiting from a trend and being at the center of it. AMD is competing directly for the biggest prize in semiconductors right now, and the results keep arriving ahead of expectations.
