AMD RDNA™ 3 Instruction Set Architecture (ISA) reference guide is now available

AMD RDNA 3 logo

We’re pleased to announce the availability of the AMD RDNA™ 3 ISA reference guide, following the release of our first RDNA 3-based GPU products. The ISA guide is most useful for anyone interested in the lowest level operation of the RDNA 3 shader core, be that shader compiler writers, tools authors, and any game or application developer that needs to optimize their shaders for the new GPU.

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.

So if you’re at all interested in some of the inner workings of the new microarchitecture and want to understand or optimize for it, check the link below!

We also don’t want you to miss our brand new blog post about a new feature of the RDNA 3 architecture – Wave Matrix Multiply Accumulate (WMMA) – which is used for accelerating Generalized Matrix Multiplication (GEMM) operations. Our engineers introduce and explain how you can accelerate AI operations using WMMA with a Hello World example. Take a look below:
