Big Tech’s Silicon Strategy: The Race to Reduce Nvidia Dependence
Amazon (AMZN) unveiled its new Trainium3 AI chip on Tuesday, the latest move in Silicon Valley’s escalating push to diversify away from Nvidia’s near-total control of high-end AI hardware.
At AWS re:Invent, CEO Matt Garman said Trainium is already a multibillion-dollar business, and the newest version delivers 4× the speed and significantly better energy efficiency than previous generations.
This isn’t happening in a vacuum:
- Google recently revealed its seventh-generation TPU (“Ironwood”) and is in talks to supply Meta with billions in chips.
- Microsoft continues developing its own silicon, though progress has been uneven.
- Anthropic—a major OpenAI rival—plans to run 1 million Amazon custom chips across its data centers by the end of 2025.
The theme is consistent across Big Tech:
Reduce exposure to Nvidia, control compute costs, and own more of the AI stack.
Amazon’s Pitch: Price, Performance, and a Strategic Edge
According to AWS VP of Compute & ML Dave Brown, Amazon’s chips deliver 30–40% cost savings for AI developers compared to Nvidia hardware—a non-trivial advantage at current training costs.
In his view, “diversity of chips in the AI market is a good thing,” and Amazon is building an ecosystem where developers can optimize for both performance and budget.
Amazon is also designing its next-generation Trainium4 chips to be compatible with Nvidia’s NVLink Fusion—a notable move suggesting Amazon wants interoperability rather than a full breakaway.
And despite the competition narrative, Amazon remains one of Nvidia’s largest customers:
- 10%+ of Amazon’s CAPEX goes to Nvidia hardware
- Amazon accounts for 7.5% of Nvidia’s total revenue
- OpenAI recently signed a $38B deal with Amazon for access to Nvidia GPUs on AWS
In short: Amazon is hedging—building its own chips while still relying heavily on Nvidia’s elite GPU stack.
The Bigger Question: Will Developers Switch?
Nvidia CEO Jensen Huang maintains that developers would prefer Nvidia chips “even if alternatives were free” because of the maturity of its CUDA software ecosystem.
That’s the barrier Amazon is trying to break.
Brown acknowledged that some customers may stay loyal to Nvidia, but pointed out that meaningful price-performance differences eventually drive migration:
“If they can see a meaningful price-performance benefit… they’ll work on moving.”
This is the core battleground:
hardware strength vs. software ecosystem vs. cost pressure.
And the pressure is rising.
WSA Take
The AI chip race is entering a new phase. Nvidia still dominates—both in performance and developer adoption—but Big Tech is throwing billions behind custom silicon in an attempt to rebalance power and cut runaway GPU costs.
Amazon’s Trainium3 isn’t a replacement for Nvidia’s top-end GPUs, but it is a meaningful competitive wedge:
Cheaper, scalable, and increasingly capable.
For investors, the broader theme is clear:
Massive demand for AI compute is reshaping the semiconductor landscape, and the strategic push toward custom chips will be one of the defining battles of 2025–2027.
