Notes
Base record uses the AMD reference layout: 1x HDMI + 3x DisplayPort. AIB port layout genuinely varies (ASUS Dual 1x HDMI / 3x DP vs Sapphire Pulse 2x HDMI / 2x DP) - AIB-dependent fields are not treated as one absolute fact. AMD never stated an implemented UHBR tier for Navi 32; do NOT inherit the RX 7900 XT/XTX UHBR13.5 value. DSC encoder and HDMI FRL grade are undocumented.
Some of this card's capabilities are not published by the manufacturer and are shown as UNKNOWN. Compatibility checks that depend on them return UNKNOWN rather than a guess. See Methodology.
