MetaX Xiyun C290
Product Overview
The MetaX Xiyun C290 is an early model of MetaX's Xiyun C series general-purpose compute GPUs, built on MetaX's proprietary XCORE 1.0 architecture and instruction set and delivered in the OAM 1.5 accelerator module form factor, positioned for AI training and inference. The Xiyun C series is MetaX's flagship product line (97%+ of revenue); based on the self-developed GPGPU architecture and paired with the MXMACA® software stack, which is fully compatible with the CUDA ecosystem, it is widely used in intelligent computing, general-purpose computing, and data analytics.
Compared with the later mass-produced Xiyun C500 (2023) / C550 / C600 (2025), the C290 is an early product of the same-generation XCORE 1.0 family with very little public specification material. Its compute range can be referenced against the XCORE 1.0 family (e.g., the C500: 15–40 TFLOPS FP32, 480 TOPS INT8, 64GB HBM2e), but the C290's official model-specific parameters are not public; the table below is marked "not disclosed/estimated" to avoid fabrication.
Core Specifications
| Parameter | Value |
|---|---|
| Architecture | MetaX proprietary XCORE 1.0 architecture and instruction set |
| Process Node | 7nm-class (estimated; same-generation XCORE 1.0 products are 7nm, officially not broken out for the C290) |
| FP32 Compute | Not disclosed (estimated; belongs to the XCORE 1.0 family, range likely near C500 level) |
| FP16 / BF16 Compute | Not disclosed (estimated; same as above) |
| INT8 Compute | Not disclosed (estimated; same as above) |
| Memory Capacity | Not disclosed (same-generation XCORE 1.0 products mostly use 64GB HBM2e; refer to official MetaX data for the C290) |
| Memory Type | Not disclosed (estimated HBM2e) |
| Memory Bandwidth | Not disclosed |
| TDP | Not disclosed |
| Interconnect | MetaXLink inter-card interconnect (estimated, consistent with the Xiyun C series) |
| Interface | OAM 1.5 (open accelerator module form factor) |
| Launch | 2022 (early model of the Xiyun C series) |
| Mass Production/Availability | In mass production (specific scale not disclosed) |
⚠️ Specification Notes: The C290 is only listed as a supported model in MetaX's developer documentation (Xiyun series user guide / out-of-band management manual); MetaX has not separately published a full parameter table for it. The "estimated" items in the table are directional references based on the parameter ranges of same-generation XCORE 1.0 architecture products (e.g., the C500) and are not measured/official C290 data; refer to official MetaX materials.

Use Cases
- ✅ AI training and inference (general Xiyun C series scenarios)
- ✅ Intelligent computing centers / general-purpose computing
- ✅ Data analytics
- ❌ Scarce public specifications; selection requires confirmation from MetaX
- ❌ Graphics rendering (the Xiyun C series is a compute GPU, not a full-function GPU)
