Innosilicon Technology has introduced the Fenghua No.3 GPU in China, a flagship part that integrates a RISC-V CPU and claims compatibility with Nvidia’s CUDA platform. Branded as Fantasy III in English on the chip, the design marks a shift from the company’s earlier PowerVR-based products and is described as fully home grown. The card features more than 112GB of HBM memory and is positioned for a wide range of workloads spanning Artificial Intelligence, gaming, CAD, medical imaging, and high-resolution displays.
At launch, company representatives withheld detailed specifications, instead emphasizing broad application support that includes scientific computing, CAD, and commercial entertainment. In a notable healthcare angle, Fenghua No.3 was billed as the first GPU with native DICOM support for medical imaging without the need for specialized displays. Demonstrations showed the card running games such as Tomb Raider and Valorant, though no benchmarks, resolutions, or frame rates were disclosed. For developers and professionals, the GPU supports DirectX 12, Vulkan 1.2, OpenGL 4.6, and hardware-based ray tracing, and it is compatible with operating systems including Windows, Android, UOS, and Kylin.
The memory configuration is pitched as well suited to Artificial Intelligence applications. According to the company, a single card can handle language models of up to 72 billion parameters, while an eight-card setup can scale to 685 billion parameters. Innosilicon also cites compatibility with several Chinese-developed Artificial Intelligence models, underscoring ambitions in the domestic ecosystem. For visual workflows, the card is said to drive 8K resolution across six monitors and support the YUV444 color format, a combination aimed at design and video professionals.
Perhaps the most striking assertion is CUDA compatibility, given that the technology is proprietary to Nvidia and seldom replicated by rival GPUs. While the announcement reinforces China’s broader push for semiconductor self-sufficiency, Fenghua No.3’s real-world performance and the practical extent of its compatibility claims remain unproven pending independent testing and detailed specifications.
