hdim-56 fallback is textbook here (1.00x x3); padding = 2.0x. Fits the corrected fused-kernel-quality theory as a prediction, not a fit: 0.50x fused/unfused -> 2.0x padding win, exactly between M3 Air (0.40x->2.6x) and M1 Max (0.87x->1.3x). At 10c matched width the ladder is 138.9/48.8/44.0ms at hdim56 but 54.3/24.4/8.9ms at hdim64 — M5's gains live almost entirely in the fused kernel, making the head-dim fix most valuable on the newest silicon. |
