MI300A GPU

The AMD MI300A is an accelerated processing unit (APU) built on the CDNA 3 architecture that uniquely combines CPU cores with GPU compute units on a single package. As AMD's first datacenter APU in the Instinct series, it represents a hybrid approach to accelerated computing, positioning itself as an alternative architecture to traditional discrete GPU solutions in the high-performance computing and AI market. The MI300A features 128 GB of HBM3 memory with 5.3 TB/s of memory bandwidth and delivers 980 TFLOPs of FP16 performance. Built on TSMC's 5nm and 6nm process nodes with 146 billion transistors, it supports Structured Sparsity to double throughput in supported workloads and includes full-chip ECC protection. The APU connects via 8 Infinity Fabric links with peak bandwidth of 128 GB/s per link, enabling direct CPU-GPU communication without traditional PCIe bottlenecks. In cloud deployments, the MI300A targets workloads that benefit from tight CPU-GPU integration, such as heterogeneous HPC applications, large-scale AI training with complex data preprocessing, and memory-intensive scientific computing where the unified memory architecture and high memory capacity provide advantages over traditional discrete GPU configurations.
