GPU Memory Access Mechanisms and Hardware Path Analysis
This article provides a detailed technical analysis of how a GPU processes memory reads, focusing on the RTX 4090's hardware path for global load operations. It explains the journey through cache hierarchies, translation lookaside buffers, and DRAM, using timing experiments to reverse-engineer undocumented aspects of GPU memory architecture.
