Up to 80 Gbps over UHBR-20 — 8K@60Hz uncompressed.
DisplayPort 2.1 (VESA, 2022) tops out at UHBR-20 (80 Gbps), enough for 8K@60Hz HDR uncompressed or 4K@240Hz. RDNA 3+ AMD GPUs include DP 2.1 UHBR-13.5 ports; RTX 50-series ships DP 2.1 UHBR-20. Note: HDMI 2.1 maxes at 48 Gbps — DP 2.1 leads on raw bandwidth for monitor connections.
