An AI coding platform, Claude Code, completed the migration of NVIDIA CUDA code to AMD's ROCm platform within half an hour, demonstrating the potential of generative AI to break down computational ecosystem barriers. On January 22, a user disclosed on the social platform Reddit that they used Claude Code to port an entire CUDA backend to AMD's ROCm platform without requiring an intermediate conversion layer.
This case has attracted market attention, with some observers suggesting it could potentially weaken the technological moat that NVIDIA has long relied on CUDA to build. However, industry insiders point out that this achievement might only be applicable to relatively simple kernel code. For codebases requiring deep hardware optimization and complex contextual understanding, the porting capabilities of AI tools still face significant limitations. NVIDIA's CUDA platform has long dominated the AI computing field, and the closed nature of its ecosystem has made it difficult for developers to migrate applications to competitor AMD's ROCm platform, which is one of the key factors for NVIDIA maintaining its market advantage. The intelligent agent framework enabled the rapid porting process. According to user johnnytshi, the only issue encountered during the migration was differences in "data layout." Claude Code operates using an intelligent agent framework that can intelligently replace CUDA keywords with their ROCm counterparts while ensuring the underlying logic of specific kernels remains consistent, going beyond simple keyword substitution. Another advantage of the tool is its simplified operational workflow. Developers do not need to configure complex conversion environments like Hipify and can complete the porting directly through a command-line interface. This convenience has practical significance for lowering the barrier to platform migration. The user did not provide detailed specifications about the type of codebase processed. Since ROCm imitates many aspects of the NVIDIA CUDA platform in its design, simple code migration poses little difficulty for AI tools. Industry professionals believe the real challenge lies with interconnected, complex codebases. Such migrations require an intelligent agent system to understand a vast amount of contextual information to effectively complete the conversion to ROCm. More critically, the core of writing kernel code lies in achieving deep hardware optimization. Some viewpoints indicate that Claude Code still falls short in optimizing for specific hardware details, such as particular cache hierarchies, which limits its practicality in high-performance computing scenarios.
