This technical deep dive explores the intricate journey of a GPU instruction, specifically a global load (LDG.E), from its execution on an NVIDIA RTX 4090 to its retrieval from memory. The analysis details how the instruction traverses through hardware components like the load/store unit and coalescer, ultimately reaching the L1 cache. The article emphasizes the complexity and undocumented nature of this process, highlighting the need for empirical timing experiments to understand GPU performance. AI
