Huang Renxun said that NVIDIA has completely cancelled the NVLink interface on the RTX 4090 graphics card, which means that in the future, everyone will not be able to use dual-card connections to obtain more powerful graphics performance. In fact, in recent years, NVIDIA has been weakening the role of multiple cards. For example, on RTX 30 series graphics cards, only the flagship RTX 3090 and RTX 3090 Ti have multiple card interfaces. In the past, even the mainstream GTX 760 can also achieve graphics performance improvement through SLI. Of course, if you want to fully utilize the performance of multi-card interaction, in addition to requiring graphics card support, the more important thing is the support of the game, otherwise it will be a simple improvement in running scores.
With the improvement of single-card performance, multi-card interaction has become increasingly useless. In addition, the power consumption of graphics cards has also increased, and dual-cards are also a huge burden on the power supply. Now with the emergence of RTX 40 series graphics cards, single-cards can meet the smooth operation at 4K resolution, and multi-card interaction has lost its value, so it is natural that it is reasonable to be cut.
