AMKR vs NVDA: How Amkor Technology and NVIDIA Compare (2026)

Short answer

AMKR (Amkor Technology) and NVDA (NVIDIA) are often compared because they share investment themes, but they are different businesses. Amkor Technology is one of the world's largest outsourced semiconductor assembly and test (OSAT) providers. NVIDIA (NVDA) designs the graphics processing units (GPUs) and the software stack that have become the standard compute platform for modern artificial intelligence. Neither is universally better: pick by which thesis you are expressing and what you already own. This is descriptive, not a recommendation.

What does Amkor Technology (AMKR) do?

Amkor Technology is one of the world's largest outsourced semiconductor assembly and test (OSAT) providers. After chips are fabricated at TSMC, Samsung, Intel, or other foundries, they need to be packaged (mounted in protective enclosures, connected to external pins) and tested before being sold. Amkor performs this packaging and testing for major customers including Apple, NVIDIA, Qualcomm, AMD, and others.

What does NVIDIA (NVDA) do?

NVIDIA (NVDA) designs the graphics processing units (GPUs) and the software stack that have become the standard compute platform for modern artificial intelligence. The company operates across four reporting segments. Data Center sells GPUs to the major cloud providers (Microsoft Azure, AWS, Google Cloud, Oracle, Meta) and to AI labs (OpenAI, Anthropic, xAI) for training and running large language models; this is now roughly 85% of revenue. Gaming covers GeForce consumer GPUs, NVIDIA's original core market. Professional Visualization sells workstation GPUs for design and simulation, and Automotive ships the DRIVE platform for assisted and autonomous driving. NVIDIA also builds CUDA, the proprietary software platform that lets developers write code that runs on its GPUs and that AI frameworks like PyTorch, TensorFlow, and JAX target first. Founded in 1993 by Jensen Huang, Chris Malachowsky, and Curtis Priem, headquartered in Santa Clara, California, and led by co-founder and CEO Jensen Huang, NVIDIA is one of the most valuable companies in the world. It designs its chips and outsources manufacturing primarily to TSMC.

AMKR vs NVDA: how do they differ?

Both fit overlapping themes, but they are not interchangeable. Amkor Technology is best understood through its own drivers, and NVIDIA through its. The useful comparison is which set of drivers and risks you want exposure to.

  • AMKR drivers: Advanced packaging for AI accelerators; US fab investment and onshore packaging.
  • NVDA drivers: Continued AI infrastructure dominance; Beyond hyperscalers: sovereign AI and enterprise.

AMKR or NVDA: which should you pick?

Pick AMKR if you believe its drivers more; NVDA if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the AMKR and NVDA guides.

The bottom line: AMKR vs NVDA

AMKR and NVDA are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined AMKR and NVDA exposure against your real portfolio. It is not an investment adviser.

FAQ

What is the difference between AMKR and NVDA?

+

Amkor Technology is one of the world's largest outsourced semiconductor assembly and test (OSAT) providers. NVIDIA (NVDA) designs the graphics processing units (GPUs) and the software stack that have become the standard compute platform for modern artificial intelligence. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.

Is AMKR or NVDA the better stock?

+

Walnut is informational, not investment advice. Neither is universally better; AMKR and NVDA suit different views and risk levels. Compare what each does, how they make money, and the risks, then decide which fits your thesis and what you already own.

Should you own both AMKR and NVDA?

+

Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both before you add the second.

What are the risks of AMKR vs NVDA?

+

AMKR: OSAT margins are structurally lower than fabless designers or pure foundries. Capex requirements for advanced packaging are substantial. Customer concentration with the largest fabless designers is meaningful. NVDA: Customer concentration is high: the top four or five hyperscalers account for roughly half of revenue, so any slowdown in their AI capex hits results directly. Those same customers are building custom AI silicon (Google TPU, AWS Trainium and Inferentia, Microsoft Maia, Meta MTIA), and AMD's MI300X and MI400 series are a real second source, even if NVIDIA still holds roughly 90% of AI training accelerator share. Geopolitics matter too: US export restrictions to China have already cut a meaningful revenue stream, and NVIDIA depends entirely on TSMC for manufacturing. The valuation is the largest risk of all: at a high multiple priced for continued triple-digit growth, the stock compresses very quickly if the AI buildout decelerates.
