Tech Giants' Custom Chips Struggle to Breach NVIDIA's Ecosystem Moat
nashnova research
Tech investor Gavin Baker argues Nvidia's real moat is not any single chip's performance but its full software-hardware ecosystem; a rival that builds one strong chip still faces the remaining eight in Nvidia's product matrix, making the true cost of the custom-chip path far higher than the market assumes.
What is Nvidia's moat, really?
Baker's core thesis: the key barrier in AI chips is not a single performance benchmark but Nvidia's full software-hardware ecosystem, built over years.
This means → a competitor cannot win by making one faster chip. It must also replicate the dev tools, software libraries, and compatibility layers — assets built with time and user scale.
In plain terms = the chip itself is the "engine," but Nvidia sells the "engine + gearbox + entire supply chain." An engine-only maker cannot enter the race.
Why do all major models still run on Nvidia?
DeepSeek, Kimi, and Qwen (千问) have followed different development paths, yet they share one trait: all run on general-purpose GPUs.
This reflects a practical reality — large models iterate fast, and developers need to adjust algorithms on the fly. The flexibility of general-purpose GPUs (chips that handle a wide range of compute tasks) matches that demand.
Baker also notes that Elon Musk's related projects chose their tech stack partly to plug into this ecosystem. This means → even the most resource-rich players are building on Nvidia's ecosystem as the foundation right now.
What trap do custom-chip rivals face?
Baker uses a vivid analogy: "tugging on Superman's cape." A company that builds one impressive chip is merely challenging one product in Nvidia's lineup.
To compete at the system level, it must match the capabilities covered by eight more chips across Nvidia's product matrix.
In plain terms = Nvidia is not a door but a wall; punch through one brick, and eight more stand behind it. This means → the real cost of the custom-chip path is far higher than the market's usual estimate.
