Nvidia vs. AMD: Which AI Chip Leader Is the Better Long-Term Investment?

Based on their latest financial results, both companies' data center businesses are growing rapidly, but a massive gap in scale remains.

Nvidia's Q2 FY2027 revenue reached $96.2 billion, up 106% year-over-year; among this, data center revenue reached $89 billion, up 117% year-over-year, already accounting for approximately 92% of total revenue. Quarterly GAAP gross margin reached 75%, and net income reached $59.69 billion.

AMD's Q2 2026 revenue reached $11.54 billion, up 50% year-over-year; data center revenue was $6.7 billion, up 107% year-over-year, accounting for approximately 58% of total revenue. The company's GAAP gross margin was 54%, and net income was $2.3 billion.

As can be seen from the above data, AMD's data center business has doubled year-over-year. However, not only is Nvidia's revenue scale roughly 8 times that of AMD, but its data center business is more than 13 times the size of AMD's, with significantly higher profitability.

Therefore, the most key difference between the two at present is that Nvidia relies on its established market advantage to continue expanding revenue, while AMD's growth logic relies more on future market share gains.

Nvidia's latest Vera Rubin platform is entering the mass production and deployment phase. It integrates Rubin GPUs, Vera CPUs, NVLink switch chips, Spectrum networking, BlueField DPUs, and AI software into a complete AI infrastructure. Currently, cloud computing providers including AWS, Google Cloud, Microsoft Azure, Oracle Cloud, and CoreWeave all plan to deploy Vera Rubin.

The significance of this model lies in the fact that Nvidia is no longer just selling GPUs, but entire AI Factories. After purchasing GPUs, customers may also continue to procure Nvidia's networking, CPUs, switch chips, and software, allowing Nvidia to capture higher value per data center.

AMD, meanwhile, is entering the same competitive landscape through its MI400 series and Helios.

The Helios rack-level platform features 72 MI455X GPUs and integrates EPYC CPUs, Pensando networking, and ROCm software. AMD also emphasizes open standards, including OCP, UALink, and UEC, aiming to win over major cloud providers by reducing customer reliance on a single vendor.

AMD's currently disclosed Helios and Instinct customers include Anthropic, OpenAI, Meta, Microsoft, and Oracle (ORCL), among others. Furthermore, AMD and Anthropic have also reached an agreement to deploy up to 2GW of MI450 series GPUs.

Therefore, AMD is no longer just a "low-cost alternative" to Nvidia GPUs, but is building its own complete AI infrastructure platform.

For Nvidia, one of its key competitive advantages remains the CUDA ecosystem.

A vast array of AI models, development tools, scientific computing software, and enterprise AI applications have been built around CUDA. Once customers establish a development and deployment system, switching GPU platforms requires re-adapting software, optimizing models, and maintaining infrastructure, creating high customer switching costs.

Meanwhile, AMD is narrowing this gap through ROCm. The company's latest MI400 platform already supports mainstream AI frameworks such as PyTorch, TensorFlow, JAX, ONNX Runtime, vLLM, and Triton. At the same time, AMD emphasizes the open-source nature of ROCm and Helios's adoption of open standards, aiming to attract large cloud computing customers who do not wish to be fully locked into CUDA.

This means future competition may take two distinct directions: Nvidia emphasizing a complete ecosystem and vertical integration, while AMD highlights an open ecosystem and multi-vendor choices.

For AMD, what truly needs to be watched over the next few years is not just the performance of the MI400 chip, but whether developers and large AI customers are willing to scale up their ROCm deployments over the long term.

From current fundamentals, Nvidia's long-term investment thesis appears relatively more complete. The company has built a comprehensive platform spanning GPU + CPU + networking + rack + CUDA software, while maintaining a 75% gross margin and substantial profitability, yet its current forward valuation is actually lower than AMD's.

Meanwhile, AMD's investment thesis rests on the premise that if its future MI400, Helios, and ROCm continue to win over customers such as OpenAI, Anthropic, Microsoft, and Meta and expand its AI GPU market share, its revenue and profit growth could enjoy significant upside elasticity from market share gains.

For long-term investors who prioritize earnings certainty, ecosystem moats, and current valuation alignment, Nvidia's fundamentals currently offer a clear advantage. Conversely, AMD is better suited for an investment thesis that accepts higher valuation and execution risks to bet on a substantial increase in its AI GPU market share.
