Unverified50% confidenceOpinionExact time
Because CUDA is deeply tied to Nvidia hardware and has accumulated more than a decade of ecosystem inertia, developers migrating to other platforms need to rewrite large amounts of code, which creates extremely high switching costs.

UnverifiedNVIDIA's core moat for maintaining high premiums in the GPU market lies in the high maturity of the CUDA software stack, as switching to other hardware platforms often involves extensive code rewriting.77% similarUnverifiedThe tight coupling of the CUDA ecosystem (framework-library-hardware) means that switching hardware often means rewriting or re-tuning low-level kernels, creating an extremely high migration barrier.76% similarUnverifiedNVIDIA's core competitive moat comes from the CUDA software ecosystem it has built over more than a decade, rather than from hardware performance alone.74% similarUnverifiedIf an inference stack depends heavily on CUDA dialects, migrating to other hardware or heterogeneous clusters requires rewriting low-level kernels, retuning, and revalidation, with engineering effort measured in person-years.71% similarUnverifiedA similar 'software drives hardware' model has precedent in the CUDA ecosystem—a free toolchain lowers the development barrier and ultimately boosts GPU sales.71% similar
