Nvidia kills off NVLink on RTX 4090

What you need to know

  • NVLink is no longer supported on the Ada Lovelace GPU architecture that powers Nvidia’s flagship RTX 4090 graphics.
  • Replacing NVLink is the PCIe Gen 5 standard.
  • Nvidia will use the freed up space from the removal of NVLink to cram in more AI processing capabilities.

Addressing reporters following the launch of the flagship GeForce RTX 4090 GPU, Nvidia CEO Jensen Huang confirmed that the company is doing away with its NVLink bridge. Replacing NVLink is PCIe Gen 5, which Huang and Nvidia claimed will be sufficiently fast to connect multiple GPUs together, and in the place of the NVLink connector is freed up space to handle more AI computing.

“The reason why we took [NVLink] out was because we needed the we needed the I/Os for something else, and so, so we use the I/O area to cram in as much as much AI processing as we could,” Huang confirmed and explained of NVLink’s absence.
