GPU FUNCTIONAL ARCHITECTURE SERIES — ENGLISH Conceptual functional diagrams, not official physical teardown drawings. The separated layers show roles; they do not represent a literal mechanical stack. Only explicitly labeled component counts represent specifications. GB200 NVL72 uses rack-wide figures; H100, H200 and B200 use the named SXM configurations. AMD specifications use individual OAM accelerators. Peak figures are not workload benchmark results. System cooling, networking and software depend on the deployment.
