The RTX 4090, which sells for more than 10,000 yuan, does not support the DP 2.0 interface. NV Response: DP 1.4 can be 8K – Fast Technology – Technology is changing the future

NVIDIA recently released the RTX 4090/4080 graphics card, the price of 7199 yuan to 12999. In the past two days, it has been criticized by various tricks or the price is expensive. NVIDIA also explained that the price increase is inevitable. After all, the price of the foundry has risen sharply. .

In addition, the RTX 4090 and RTX 4080 graphics cards have a small regret, that is, the video interface, NVIDIA gave HDMI 2.1, but the DP interface is still DP 1.4a, and there is no latest DP 2.0 interface .

For this, NVIDIA gave an official explanation in the community Q&A,The DP 1.4 interface is said to now be able to support 8K 60Hz output, and there is still a long way to go before consumer monitors support the DP 2.0 interface..

In short, NVIDIA doesn’t give DP 2.0 interface stingy, but they think that DP 1.4 is enough, after all, 8K 60Hz is now a minority, and there are not many monitors that support DP 2.0 , it is still early to become mainstream.

Currently, the most active DP 2.0 interface in the graphics card is Intel.Thousand dollar graphics cards like A380 are given 3 DP 2.0,However, the actual use is also residual blood, which runs under PI 1.4.

The DP 2.0 specification was released as early as 2019. The theoretical bandwidth was increased to 80Gbps in one fell swoop, and a new 128/132b encoding mechanism was adopted to increase the efficiency to 97%, and the actual usable rate was as high as 77.4 Gbps, which corresponds to full DP 1.3 / 1.4 Three times, much higher than the theoretical bandwidth of HDMI 2.1 of 48Gbps.

It’s just that the commercial support for DP 2.0 is not very good. Even if the standard is free, it is not as popular as the paid HDMI 2.1 interface It is not surprising that graphic card manufacturers are not active on DP 2.0.

The RTX 4090, which sells for more than 10,000 yuan, does not support the DP 2.0 interface.  NV Response: DP 1.4 can be 8K
