-## 🏎️ Performance Claims
-
-**Honest & Verifiable:**
-- ❌ Never claim: "Faster than NVIDIA CUDA on H100"
-- ✅ Always claim: "Optimized ROCm vs Baseline HIP (straight hipify output)"
-
-**Why AMD Wins:**
-- **Memory-bound kernels**: MI300X's 5.3 TB/s vs H100's 3.35 TB/s bandwidth
-- **Large models**: 192GB memory eliminates multi-GPU sharding
-- **Wavefront efficiency**: 64-thread wavefronts vs 32-thread warps
