AMD Radeon RX 7000 Series graphics cards may support DisplayPort 2.0

pcinvasion.com:

It turns out that AMD Radeon 7000 Series graphics cards might just feature DisplayPort 2.0 support. Twitter user Kepler_L2 recently posted a link to an AMD driver patch that references support for the new UHBR20 standard associated to DisplayPort 2.0. This will enable data throughput up to 80 Gbps, allowing for higher resolution gaming at higher framerates.

When most gamers think of image quality and how to get the best framerates, they likely think of hardware first. But all hardware needs to go through cables to reach your display, where you see images at certain framerates. As the hardware continues to get better and become capable of supporting higher framerates and resolutions, so too must the cabling evolve to deliver all of that information on time.

What makes DisplayPort 2.0 such a big deal is that it will more than double the throughput of today’s DisplayPort 1.4a spec of 32.4Gbps. It’ll also blow the HDMI 2.1 spec out of the water, which tops out at 48 Gbps.

HDMI 2.1 is the current top spec for cable throughput, allowing uncompressed 4K resolution images at 120 fps. At 1440p, HDMI 2.1 manages about 240 fps uncompressed. At 1080p, about 360 fps is possible without compression.

Looks like RDNA3 supports the full DisplayPort 2.0 spec (UHBR20)

The important takeaway is that higher throughput removes the need for compression techniques which can worsen the quality of images through reducing color depth, introducing artifacts (inaccuracies from the native image), and other undesirable compromises. For instance, early high refresh 4K displays had to rely on compression to make the limited throughput of the HDMI 2.0 spec work. DisplayPort 2.0 pretty much does away with this dilemma
