Ettore Di Giacinto 37cbc089b0 bench(dense): Qwen3-32B dense parity - dense has the kernel gap too (PP 7.6-32x)
vLLM W4A16 vs llama Q4_K_M dense: prefill 7.6-32x behind (llama plateaus ~765,
vLLM scales to 24.4k); decode ~parity at B=1 (weight-bandwidth-bound), 2.2x at
B=64. Full NVFP4 (W4A4) hangs on this vLLM/GB10 stack - W4A16 used. Decision:
the Lever-3 kernel track must ALSO deliver a non-grouped FP4 dense GEMM, not just
the MoE grouped GEMM (dense GEMM is the simpler first kernel to land).
