Hot Chips 2026: CUDA Targets RISC-V – By Chester Lam

NVIDIA has confirmed that it will extend support for its CUDA programming platform to include RISC-V processors, a significant development announced at Hot Chips 2026. This initiative aims to enable GPU acceleration on open-source, royalty-free architectures, potentially transforming hardware and software ecosystems. The announcement signals a strategic shift for NVIDIA, which has traditionally focused on proprietary architectures, and could influence broader industry adoption of RISC-V in high-performance computing.

The company stated during its presentation at Hot Chips 2026 that CUDA, its flagship parallel computing platform, will soon support RISC-V, an open-source instruction set architecture (ISA) gaining popularity in academia, industry, and government sectors. NVIDIA’s move indicates an intent to make GPU programming more accessible across diverse hardware platforms, including those based on RISC-V cores. This decision aligns with industry trends toward open hardware and software ecosystems, aiming to reduce reliance on proprietary architectures like x86 and ARM.

While NVIDIA did not specify a precise timeline for the release or the technical scope of RISC-V support, sources close to the company suggest that initial support could be integrated into upcoming CUDA updates within the next year. The company emphasized that this effort would involve collaboration with RISC-V ecosystem members to optimize performance and compatibility. NVIDIA also highlighted that this initiative could facilitate more flexible and customizable hardware configurations, especially for embedded, edge, and data center applications.

Implications for GPU Development and Open Hardware Ecosystems

This announcement could reshape the landscape of GPU computing by enabling CUDA-accelerated applications on RISC-V hardware, which is known for its open-source licensing and flexibility. For developers, this means broader access to GPU programming tools across diverse hardware platforms, potentially lowering barriers to entry and fostering innovation. For the industry, supporting RISC-V could accelerate the adoption of open hardware designs, promote competition, and reduce dependence on traditional proprietary architectures. It also signals a strategic move by NVIDIA to remain relevant as the industry shifts toward open standards and customizable hardware solutions.

NVIDIA’s Strategic Shift Toward Open Architectures

Historically, NVIDIA’s CUDA platform has been optimized primarily for NVIDIA’s own GPUs, which rely on proprietary architectures. However, the industry trend toward open-source hardware and alternative ISAs like RISC-V has gained momentum over recent years. RISC-V, an open-source ISA developed at UC Berkeley, has seen increasing adoption in academia, startups, and even some industry giants, due to its flexibility and royalty-free licensing model. NVIDIA’s move to support RISC-V in CUDA reflects a recognition of this shift and a desire to expand its ecosystem beyond traditional boundaries.

Prior to this, some industry observers speculated that NVIDIA might develop dedicated support for emerging open architectures, but official confirmation was pending. The company’s participation at Hot Chips 2026 and its announcement mark a notable departure from its previous focus solely on proprietary hardware, signaling a broader strategy to embrace open standards and foster innovation across hardware and software layers.

“NVIDIA’s decision to support RISC-V in CUDA could open new pathways for developers and hardware manufacturers, promoting a more open and flexible GPU ecosystem.”

Details of CUDA Support for RISC-V Still Unclear

While NVIDIA has announced support for RISC-V in CUDA, specific technical details, such as the scope of support, performance benchmarks, and release timelines, remain undisclosed. It is not yet clear whether initial support will cover all CUDA features or be limited to specific applications or hardware configurations. Industry analysts and developers are awaiting further technical disclosures from NVIDIA to assess the practical implications of this support.

Next Steps Include Developer Tools and Ecosystem Collaboration

Following this announcement, NVIDIA is expected to release detailed technical documentation and developer tools to facilitate RISC-V support in CUDA. The company may also engage with RISC-V ecosystem partners to optimize hardware-software integration. Industry observers anticipate that the first compatible hardware platforms could appear within 12 to 18 months, with broader adoption depending on developer feedback and ecosystem maturity. NVIDIA’s ongoing collaboration with RISC-V community members will likely shape the future roadmap of this initiative.
