We’re pleased to announce the availability of the AMD RDNA™ 3.5 Instruction Set Architecture (ISA) reference guide. The ISA guide is useful for anyone interested in the lowest level operation of the RDNA 3.5 GPU architecture, be that shader compiler writers, tools authors, and any game or application developer that needs to optimize their shaders.

The guide covers the whole shader core execution model, including program state, the various wave execution models, how the shader core interacts with the memory hierarchy, the available instructions including their encodings, and lots more.
