DisplayPort 2.1 bandwidth
DisplayPort 2.1 UHBR20 is rated 80 Gbps and carries 77.37 Gbps of video after 128b/132b encoding. At 8-bit without compression it carries 1080p up to 884 Hz, 1440p up to 609 Hz, 3440x1440 up to 491 Hz and 4K up to 323 Hz. That is 2.98 times the 25.92 Gbps of DisplayPort 1.4.
DisplayPort 2.1 UHBR20 carries DSC, so modes over its payload can still fit when both ends support it.

Results use PC monitor timings (VESA CVT reduced blanking v2 as the headline), not the TV and console timings in CTA-861, so a TV or console may need more bandwidth than shown. RGB/4:4:4 color. DSC verdicts are at maximum compression (8 bpp), the lowest rate VESA's DSC standard allows for 4:4:4, and show the compression each mode needs.
