# Performance summary These figures are selected from the PyC H100 kernel-lab campaign and are included as orientation, not as universal benchmark claims. | Lane | Shape | Result | | --- | --- | --- | | Hopper WMMA FP16 | 1024^3 | 0.105 ms, 20.473 TFLOPS | | Hopper WMMA BF16 | 1024^3 | 0.102 ms, 21.024 TFLOPS | | Hopper cuBLASLt BF16 control | 4096^3 | 0.162 ms, 846.466 TFLOPS | | Hopper async square K64 | 4096^3 | 0.9252 ms in the captured profile | The engineering progression is: shared-memory tiling and reuse, WMMA Tensor Core execution, BF16/FP16 comparison, `cp.async` double buffering, CTA shape and warp-work assignment, K-stage depth, and finally a cuBLASLt control lane. Always interpret a result together with GPU model, architecture, CUDA version, matrix shape, warmup/repeat policy, and correctness mode.
