TSM’s Record Sales Say AI Chips Are Booming. The Nvidia-AMD Fight Is Now About Who Keeps the Margin

NVIDIA Corporation (NASDAQ:NVDA) and Advanced Micro Devices, Inc. (NASDAQ:AMD) are competing for AI accelerator share, but Taiwan Semiconductor Manufacturing Company's latest sales show one thing both companies agree on: demand for advanced silicon remains enormous.
TSM reported September 10 that August revenue reached a record NT$514.81 billion, up 53.3% from a year earlier. Concerns that TSM could raise prices by as much as 10% next year nevertheless weighed on semiconductor shares.
That creates an interesting dynamic for Nvidia and AMD. Both companies benefit from rising AI-compute demand, but both depend on a manufacturing ecosystem whose suppliers are gaining bargaining power.

Nvidia Has More Room to Defend the Margin
NVIDIA Corporation (NASDAQ:NVDA) has a bull case built around its platform advantage. CUDA, networking, NVLink and rack-scale systems make the company much harder to displace than a standalone chip vendor. Customers increasingly evaluate total system performance rather than raw accelerator specifications.
The bear case is cost. Foundry, HBM and advanced-packaging suppliers all want a larger portion of AI system economics. Nvidia has historically enjoyed extraordinary gross margins because demand exceeded supply and its software ecosystem was difficult to replicate. The more expensive the rest of the bill of materials becomes, the harder those margins become to defend.
AMD Needs Share Gains to Overwhelm the Cost Pressure
Advanced Micro Devices, Inc. (NASDAQ:AMD) has a bull case built around hyperscalers desperately wanting competition. A credible alternative can win major deployments without overtaking Nvidia industry-wide. Each large customer also gives AMD more software feedback and improves the maturity of its ecosystem.
AMD's bearish problem is that it may have less ability than Nvidia to pass higher manufacturing costs through to customers. A challenger often needs aggressive pricing precisely when input costs are moving against it.
Hedge-fund sentiment became more bullish on both stocks in Q2. Nvidia ownership rose to 285 funds from 275, while AMD surged to 164 from 134. Short interest remained modest, although it was higher for AMD: approximately 2.5% of AMD's float was short as of August 14 versus roughly 1.2% for Nvidia.
The valuation distinction comes down to certainty versus optionality. Nvidia commands the premium because it owns the established ecosystem. AMD can offer greater upside if accelerator share rises materially, but investors are underwriting a competitive outcome that has not yet been fully achieved.
The record TSM numbers support both companies' demand outlooks, but Nvidia remains better positioned to absorb higher supply-chain costs. AMD is the higher-beta bet that hyperscaler demand for a second accelerator platform becomes large enough to overwhelm that margin disadvantage.
While we acknowledge the potential of NVDA and AMD as investments, we believe certain other AI stocks offer greater upside potential and carry less downside risk.
