AMD Radeon RX 7000 series maybe support DisplayPort 2.1 interface

by ddos ·

AMD has announced that it will launch the RDNA 3 architecture GPU on November 3, 2022, which is obviously the Radeon RX 7000 series graphics card. As AMD’s first consumer-grade GPU in an MCM multi-chip package, many players are looking forward to the performance of the new generation of graphics cards, but previous reports said that the top models of the Radeon RX 7000 series are likely to be difficult to compete with the GeForce RTX 40 series.

Recently, Twitter user @KyleBennett revealed that multiple sources of information show that AMD’s Navi 31 will support the upcoming DisplayPort 2.1 interface. At present, the Video Electronics Standards Association (VESA) has not yet confirmed the DisplayPort 2.1 specification, and the specific specifications are unclear.

Earlier reports pointed out that AMD has conducted UHBR (Ultra-High-Bit-Rate) certification for DisplayPort 2.0 and will support UHBR10 (40Gbps), UHBR13.5 (54Gbps), and UHBR20 (80Gbps). Among them, UHBR20, the highest specification, has a link rate much higher than HDMI 2.1 (48Gbps) and DisplayPort 1.4a (32Gbps) currently seen on the market, and can theoretically achieve a single 16K (15360 x 8460) display @60Hz / 30 bpp 4:4:4 HDR (DSC), or a single 10K (10240 x 4320) monitor @60Hz/24 bpp 4:4:4 (uncompressed) output standard.

In contrast, NVIDIA’s GeForce RTX 40 series currently only supports the DisplayPort 1.4a interface, which can achieve a single 8K (7680 x 4320) display @ 60Hz, but this requires the support of DSC video compression technology. In the Q&A, Nvidia officials explained the problem, saying that “Support for DisplayPort 2.0 in consumer gaming displays are still a ways away in the future.”. Among the discrete graphics cards currently available in the consumer market, Intel’s latest Arc A series graphics cards support DisplayPort 2.0.
