Methodology Note
Performance estimates for the Radeon PRO W7900are based on InferenceBench's roofline performance model with CUDA kernel-level optimization including FlashAttention v2 and PagedAttention. Memory calculations account for model weights (48 GB GDDR6 available), KV-cache allocation, and activation memory. Throughput predictions use the Radeon PRO W7900's rated 864 GB/s memory bandwidth and 122 BF16 TFLOPS compute capacity as roofline ceilings, with empirical correction factors per GPU architecture (rdna3).
