# LABS on a GH200: Exponent 1.24 to the Proven Optimum, Beside the QAOA Exponents

GPU Search vs lMAts; Exact Branch-and-Bound Matches All 46 Published Optima.

1.240 GPU wall-TTS base b, N = 40–66

46/46 exact optima equal the P&M table

3 of 6 N > 66 best-knowns reached (lMAts 0)

- GPU wall TTS ∝ 1.240N (N 40–66) vs lMAts 1.352N
- Exact B&B: 46/46 optima equal the published table
- N = 67, 71, 75: GPU reaches the best-known value; lMAts at none
