==========================================
Graphics Register Bus Manager (GRBM)
==========================================

The Graphics Register Bus Manager (GRBM) exposes coarse-grained utilization for the whole GPU and for individual Shader engines (SEs).
These counters summarize how busy the graphics/compute complex is; pair them with Workgroup Manager (SPI), Workgroup processor (WGP), and cache chapters when you need root-cause detail.

The sections below list RDNA3.5 (gfx115x) GRBM-derived utilization tables.

.. Note::
   For AMD Instinct-centric Shader engine metrics, see :doc:`../cdna/shader-engine`.
