Methodology Note
Performance estimates for the Instinct MI300Xare based on InferenceBench's roofline performance model with CUDA kernel-level optimization including FlashAttention v2 and PagedAttention. Memory calculations account for model weights (192 GB HBM3 available), KV-cache allocation, and activation memory. Throughput predictions use the Instinct MI300X's rated 5300 GB/s memory bandwidth and 1307 BF16 TFLOPS compute capacity as roofline ceilings, with empirical correction factors per GPU architecture (cdna3).
