According to WccfTech news, after AMD officially announced the RNDA 3 graphics card product that had been warmed up as early as the Ryzen 7000 series processor conference, it will be officially launched on December 13. The most eye-catching features of the new generation of AMD Radeon graphics cards, in addition to the new architecture of RNDA 3, the high energy efficiency repeatedly emphasized at the press conference, and the announcement of support for the new generation of high-bandwidth interface DisplayPort 2.1, its highest video signal output specification can reach 8K165Hz, 4K480Hz or other similar levels. A few days ago, MSI’s MEG 342C QD-OLED display is expected to be officially released at the CES show in the United States next month. This display has a 34-inch 3440×1440@175 Hz specification and is also equipped with a DP 2.1 interface.
We mentioned DP 2.0 in the past content, as the successor of DP 1.4/1.4a standard, it mainly realizes the transmission bandwidth of up to 80Gbps bit rate, and brings the new certification that the Video Electronics Standards Association (VESA) likes most: UHBR products, covering graphics cards, docking station chips, display scalar chips, PHY repeater chips, and DP40/DP80 data cables, etc. Popular Science|Display Port DP historical version comparison; DP 2.1 is a new standard after adopting the USB Type-C interface, cable, and USB 4 standard without changing the basic performance specifications of DP 2.0. Products claiming support for the VESA standard meet the high-quality benchmarks established by VESA and enable robust use.
DisplayPort 2.1 is long overdue but commercialized very fast
On the one hand, nowadays TVs, graphics cards, and monitors are all equipped with HDMI interfaces; while on TVs, DVD players, power amplifiers, game consoles, and other equipment, DP interfaces cannot be seen. On the other hand, with the advent of the 8K era, the HDMI organization announced as early as 2017 the HDMI 2.1 standard that can well correspond to 8K, 120Hz display devices, and supports VRR variable refresh rate technology, this standard has long been It is widely used in various home appliances and PC equipment. In contrast, the Video Electronics Standards Association (hereinafter referred to as VESA) behind the DP standard seems to be a bit slow in responding to the demand for “Ultra HD”. In June 2019, two years after the announcement of the HDMI 2.1 standard, the DP 2.0 standard, which can also support 8K 60FPS and 8K 120FPS ultra-clear video transmission, came late. To make matters worse, after more than two years, we have not seen any mainstream PC or monitor products equipped with this interface. Obviously, for the entire PC camp, this is a very passive situation. Because the HDMI 2.1 standard has been adopted by more and more ultra-definition and high-definition devices, and this will inevitably mean that the industry status of DP will further shrink. Under such circumstances, in late October 2022, the PC industry finally sounded the clarion call to fight back, not only announcing the DisplayPort 2.1 specification.
More importantly, VESA also announced a large number of important products, including but not limited to the latest GPU, docking station chips, monitor scalar chips, PHY repeater chips, and various shapes of DP40/DP80 cables and interfaces that have passed the DP 2.1 technical certification simultaneously and can be put into the market immediately. As we all know, it usually takes months or even years for the latest industry specification to be adopted by actual products after it is published. Therefore, it is quite rare that a technical standard like DP 2.1 has just been announced, and the product (although it is a relatively upstream component) is already ready. So, how does DP 2.1 achieve “fast shipment”?
The reason is actually very simple its own standard has very limited changes compared to DP 2.0 released in 2019. At the same time, before the announcement of the new standard, VESA conducted technical cooperation with a large number of manufacturers that can produce DP2.0 standard-related equipment and re-tested all DP2. Certification, and finally confirmed that they “all comply with the DP2.1 standard”. In any case, AMD RX 7900 series graphics products began to support DP 2.1, which means that the new high-performance interface applications finally have a beginning. After all, if no one starts this, the entire industry may hesitate in the question of “chicken or the egg”. Fortunately, AMD and Samsung have reached an agreement. At the same time, the press conference revealed the Odyssey Neo that supports DP 2.1. News on 8K ultrawide monitors like the G9
