GeForce RTX 40-series graphics cards have lost the NVLink interface and will not receive PCIe 5.0 support

After yesterday’s presentation of GeForce RTX 40 series graphics cards based on the Ada Lovelace architecture, NVIDIA CEO Jensen Huang said that these new products lack the NVLink interface. Therefore, having multiple next-gen video cards working together in a gaming PC will not work.

According to Huang, the company has dropped the NVLink interface and opted for the transistorized budget of Ada Lovelace’s GPU generation.for something else“. The company’s engineers were specifically tasked with using the largest possible area of ​​​​the processor chip for the blocks responsible for the computing power associated with the operations of AI and machine learning algorithms.

Note that NVIDIA long ago took the path away from using bundles of multiple consumer video cards. With the debut of GeForce RTX 20-series graphics cards, the company abandoned SLI and replaced it with NVLink, but only in older graphics cards, starting with the RTX 2080. And in the last generation, NVLink was only in the flagship GeForce RTX 3090 and RTX 3090 Ti

The company also confirmed that GeForce RTX 40 series graphics cards do not support PCIe 5.0. “Ada does not support PCIe Gen 5, but a PCIe 5.0 power cable adapter is included.”, – said an NVIDIA representative in an interview with the TechPowerUp portal. Remember that GeForce RTX 40 Series graphics cards use the new 12+4-pin 12VHPWR power connector, which conforms to PCIe 5.0 and ATX 3.0 standards.

“The current PCIe 4.0 interface has enough bandwidth, so we decided that PCIe 5.0 is not required for the new generation of accelerators. In addition, the large video buffer and large L2 cache in the Ada graphics chips reduce the load on the PCIe interface.”added to NVIDIA.
