Apple is fighting for TSMC capacity as Nvidia takes center stage

๐Ÿ“ Discussion Summary (Click to expand)

Based on the Hacker News discussion, here are the 5 most prevalent themes regarding Apple's changing position with TSMC:

1. The Nature of the Market Shift: Business as Usual vs. Karma

Many commenters view the situation not as cosmic justice, but as a standard market dynamic where pricing power shifts between large players. However, some see poetic justice given Apple's historical dominance in securing manufacturing capacity.

  • "Is it karma or is it just normal business activities? When you're a large player like this you get pricing power. If another large player moves in and also has pricing power then negotiations and things like that take place." โ€” ericmay
  • "Ha! Well if it isn't karma that has come for Apple." โ€” outside1234
  • "How the turn tables" โ€” mikelitoris

2. The Business Case for TSMC Prioritizing AI (Nvidia)

A major theme is that TSMC benefits from having both a "stable anchor tenant" (Apple) and a "high-volume spender" on bleeding-edge nodes (Nvidia). Commenters argue that Nvidia's willingness to pay premium prices for early, low-yield capacity subsidizes the R&D for everyone else, while Apple provides the volume later.

  • "Nvidia is the high-frequency trader hammering the newest node until the arb closes. Stability usually trades at a discount during a boom... Apple is the anchor tenant that keeps the lights on." โ€” Fiveplus
  • "Nvidia's willingness to pay exorbitant prices for early 2nm wafers subsidizes the R&D and the brutal yield-learning curve for the entire node... You need a high-volume, smaller-die customer (Apple) to come in 18 months later, soak up the remaining 90% of capacity." โ€” Fiveplus
  • "TSMC isn't running a charity, it sells capacity to the highest bidder." โ€” epolanski

3. Appleโ€™s Binning Flexibility vs. Nvidiaโ€™s Margins

Discussion frequently turns to the technical and economic differences between the two companies' products. Commenters debate Apple's superior ability to bin chips across a wide product range (iPhone to Mac) versus Nvidia's ability to absorb massive costs due to extreme margins on AI silicon.

  • "Nvidia can disable 10% of the cores on a defective GPU and sell it as a lower SKU. Does Apple have that same flexibility with a mobile SoC where the thermal or power envelope is so tightly coupled to the battery size?" โ€” Fiveplus
  • "With current AI pricing for silicon, I think the mathโ€™s gone out the window." โ€” alex43578
  • "If Nvidia can sell a reticle-sized package for 25k-30k USD, they might be perfectly happy paying for a wafer that only yields 30-40% good dies." โ€” Fiveplus

4. The Geopolitical Risk of Reliance on Taiwan

The precariousness of the supply chain due to tensions with China is a recurring topic. Users discuss the potential for conflict, the "scorched earth" policies TSMC might employ, and the slow progress of diversifying manufacturing to the US.

  • "Sneak preview of the TSMC shortage that will sweep the world in 2027 when China takes Taiwan and the TSMC scuttles their chip fabs on the island." โ€” tim-tday
  • "TSMC has the ability to remotely destroy all of their main fab equipment in the event the Chinese are invading Taiwan." โ€” edm0nd
  • "USA has been strategically re-homing TSMC to the US mainland for a long time now. 30% of all 2nm and better technologies are slated to be produced in Arizona by 2030." โ€” petcat

5. Apple's Capacity to Pivot or Build Their Own Fab

There is significant debate over whether Apple can or should build its own fabrication plants to regain control. The consensus leans toward it being too capital-intensive and complex, with speculation that Apple will instead diversify by becoming a major customer for Intel's foundry services.

  • "Apple has less cash available than TSMC plans to burn this year... Starting from zero is a non-starter. It just cannot happen anymore." โ€” bob1029
  • "Apple can and should do it again! [referring to Apple investing in TSMC early on]" โ€” SecretDreams
  • "Explains why Apple is looking to diversify their fabs with Intel. If Intel can stay on their current trajectory and become a legitimate alternative they will do very well." โ€” etempleton
