Innosilicon launches Fenghua 3 GPU with RISC-V CPU integration and 112GB+ memory
Innosilicon has officially announced its third-generation GPU, the Fenghua 3. The company calls it the first domestically designed full-function GPU, combining a RISC-V CPU with a CUDA-compatible graphics core on a single card.
Unlike earlier Fenghua models based on PowerVR IP, Fenghua 3 adopts OpenCore’s RISC-V Nanhu V3 project as its foundation. Innosilicon claims the new GPU can handle a wide range of workloads, from AI training and large-scale scientific computing to CAD, medical imaging, and gaming (importantly: cloud gaming).

For graphics, the card supports DirectX 12, Vulkan 1.2, and OpenGL 4.6, with hardware ray tracing enabled. The company demonstrated the GPU running games such as Tomb Raider, Delta Force, and Valorant, although no frame rate or settings data was shared. Fenghua 3 also supports up to six 8K monitors at 30 Hz. However, we should note that the company doesn’t mention desktop/laptop gaming specifically but cloud gaming as one of the use cases:

Fenghua 3 official highlights
- Over 112GB high-bandwidth memory for large-scale AI workloads
- Single card supports 32B/72B models, eight cards can run 671B models
- First Chinese GPU with hardware ray tracing support
- First GPU worldwide with DICOM medical grayscale display
- vGPU design architecture with hardware virtualization
- Supports DirectX 12, Vulkan 1.2, OpenGL 4.6, and up to six 8K displays
- Domestic design based on OpenCore RISC-V CPU and full set of IP
For AI, the card is equipped with more than 112GB of high-bandwidth memory, the highest capacity yet on a domestic GPU. A single card can handle 32B and 72B-parameter models, while eight cards can reportedly support DeepSeek 671B and 685B models. Innosilicon also confirmed compatibility with Qwen 2.5, Qwen 3, and other model families.
Fenghua 3 also brings features like vGPU virtualization for data centers, DICOM medical-grade grayscale display support, and YUV444 color for CAD and video editing. The card works with Windows, Android, Tongxin, and Kylin Linux systems.
Chinese media are not mentioning when the first products featuring this GPU would be released. However, large memory, support for DirectX12, Windows and hardware acceleration for ray tracing sound very promising.
