Tracing an LDG Instruction on the RTX 4090

An article published on August 13, 2026, follows an LDG.E SASS instruction through the RTX 4090’s hardware units and memory hierarchy, including reverse engineering of undocumented details.

Published on August 13, 2026, the article follows an LDG.E SASS instruction through the hardware units and memory hierarchy of an RTX 4090. Its scope is to show, at the hardware level, how memory reads travel through the card, including reverse engineering of details that are not documented.

The available summary does not specify further findings. To consult and verify the work, read the original article and check which observations are presented as measurements, interpretations, or details inferred through reverse engineering; compare claims with relevant technical documentation where available. If you use AI to study the topic, avoid sending internal or identifiable data without authorization.
