An enthusiast under the nickname Kepler on his social networks shared very interesting information that he managed to get after a detailed study of drivers from AMD. In the software code, he found data indicating that the Radeon RX 7000 graphics card supports the latest DisplayPort 2.0 interface, which operates in VESA UHBR20 mode. This indicates that the new generation of red team video cards will boast huge bandwidth up to 80 GB / s. And this, of course, opens up a huge space for the implementation of various functions and capabilities.
In order to understand how advanced this technology is, it is worth comparing the bandwidth of DisplayPort 2.0 with the capabilities of the current most popular HDMI 2.1 standard – the new product has 32 GB / s higher bandwidth. What’s more, it has 48 GB/s more bandwidth than DisplayPort 1.4a – more than twice. Accordingly, thanks to such high bandwidth, the Radeon RX 7000 graphics card will be able to run a picture in 16K resolution with DSC compression, or up to 10K without compression, or, most interestingly, the graphics accelerator will be able to display two signals at once in 8K resolution with support for HDR technology with frequency 120 Hz.
However, it is too early for potential buyers of the Radeon RX 7000 video card to rejoice at such cool characteristics. Firstly, bandwidth is one thing, but whether a graphics accelerator can produce an 8K picture at an adequate frame rate is another. Modern top-end graphics cards struggle to handle 4K at 60 FPS. Secondly, VESA promised to release monitors with DisplayPort 2.0 support by the end of 2021, but this, unfortunately, did not happen. And thirdly, even if the video card can pass such information through itself, it is not at all necessary that content developers will use it in the foreseeable future.
