GPU Conditional Branching: Myth vs. Reality

2025-02-09

This article debunks a long-standing misconception in computer graphics: ternary operators in GPUs are not conditional branches. The author uses code examples and assembly code analysis to show that ternary operators or if statements in GPUs implement conditional move instructions, not branch jumps that alter the instruction pointer. These conditional moves are more efficient, and the supposed 'optimization' using the `step()` function actually reduces performance. The article calls for correcting this 20-year-old misunderstanding.
