On some GPUs (eg GCN/RDNA) 24bit integer muls/mads are 4x faster than 32bit ones. 24bit instructions are not exposed in HLSL/GLSL but you can encourage the compiler to use the 24bit intrinsics by zeroing the 8 most significant bits, if the range allows it, for faster integer muls/mads.
Agility SDK 1.720-preview has been released with Linear Algebra Matrix support which replaces Cooperative Vectors and WaveMMA for hardware accelerated matrix operations, access to wave threadgroup index, and increased groupshared memory among others.

Indeed! Used this a while ago to make a 24-bit hash optimized for GPU and got some really really good wins compared to the commonly used version of PCG out there.
The full-rate 24-bit multiply-adds are the real workhorse of it 🧡
