Warp Divergence Stability Across NVIDIA Pascal to Blackwell Architectures
July 25, 2026
Analysis across Pascal, Ampere, Hopper, and Blackwell generations shows that divergent paths serialize linearly with the number of paths k. Execution efficiency scales as 32/k, demonstrating that warp divergence behavior remains consistent despite architectural shifts since Volta.
