AMD machine-readable GPU ISA documentation

AMD’s machine-readable GPU ISA specifications are a set of XML files that describe AMD’s latest GPU Instruction Set Architectures (ISAs): instructions, encodings, operands, data formats and even human-readable description strings. Explore the XML files directly or use the IsaDecoder API for easy access and quick decoding of single instructions and whole kernels.

Supported architectures:

  • AMD CDNA™ 4 (AMD MI350 Instinct)
  • AMD CDNA™ 3 (AMD MI300 Instinct)
  • AMD CDNA™ 2 (AMD MI200 Instinct)
  • AMD CDNA™ 1 (AMD MI100 Instinct)
  • AMD RDNA™ 4
  • AMD RDNA™ 3.5
  • AMD RDNA™ 3
  • AMD RDNA™ 2
  • AMD RDNA™ 1

What’s new

Updated September 2025

  • amdgpu_isa_cdna4.xml is a new XML specification for CDNA4.
  • All MI* specifications have been renamed to “cdna*”, so:
    • amdgpu_isa_mi100.xml -> amdgpu_isa_cdna1.xml
    • amdgpu_isa_mi200.xml -> amdgpu_isa_cdna2.xml
    • amdgpu_isa_mi300.xml -> amdgpu_isa_cdna3.xml

AMD GPU IsaDecoder API and more

We’ve made available a set of C++ tools for parsing and using AMD’s machine-readable GPU ISA specifications:

  • The AMD GPU IsaDecoder API makes it easy to parse the specification XML files, decode instructions, and even decode whole shaders.
  • The explorer::Spec experimental API lets you iterate over the elements of a given specification file.
