Official data shows that at MXFP4 and MXFP6 precision, the MI350P achieves peak computing power of 4.6 PFLOPS, a figure that leads among current mainstream AI accelerators.
MXFP formats are emerging low-precision floating-point formats specifically optimized for AI inference. Compared to traditional FP16 or FP32 formats, MXFP can significantly improve computational efficiency while maintaining model accuracy, making it an ideal choice for large model inference. The MI350P natively supports MXFP6 and MXFP4 formats, meaning users can achieve optimal performance without complex format conversions.
For sparse computing, computing power reaches 2.3 PFLOPS at MXFP8 and FP16 precision. Sparse computing represents an important AI acceleration technique that, by leveraging sparsity characteristics in neural networks, can further improve computational efficiency without losing accuracy. AMD’s continuous investment in this field enables the MI350P to better handle various complex AI workloads.
For traditional high-performance computing scenarios, the MI350P also delivers exceptional performance.
