Compute-bound
Beginner
A job is limited by math when the math parts of the chip are the slow part. They’re busy all the time, and numbers arrive fast enough.
Novice
A workload whose run time is set by how many operations it needs, because it does more work per byte than the chip’s ratio of compute to bandwidth. More math hardware would speed it up.
Expert
Arithmetic intensity above the ridge point. Its achieved rate is then capped by peak compute or by a lower ceiling (missing parallelism, the wrong instruction mix, tile or wave quantization).
Explained in What the workload needs (Architectures).
