Databook covering the AMD Polaris 21 GPU, packed as a PDF in a 1.25 MB RAR. It describes the chip's ball-out, supply rails, GDDR5 memory interface and electrical limits. When repairing a graphics card, this helps identify which power domains must be present, which pins link to memory and display connectors, and how the chip expects to be strapped. Because it documents the processor rather than a specific card design, confirm the GPU marking and use it together with the card's schematic or boardview.
