AMD Instinct hardware facts for kernel authoring, rooflines and communication — MI350X/MI355X (gfx950, CDNA4) and MI300X/MI325X (gfx942, CDNA3) — with the spec peaks, how to measure what a node achieves, the memory hierarchy, LDS banks, MFMA and block-scaled matrix instructions, the gfx950 ISA additions, XGMI/collective bandwidth, and where each fact comes from. Use when writing or tuning a kernel, pricing a direction against its floor, writing a kernel plan, reading a roofline, or deciding whether a kernel is compute- or bandwidth-bound.
