Nvidia CEO confirms that Ada Lovelace architecture does not support NVLink

After NVIDIA released the Ada Lovelace architecture GPU, many people found that the GeForce RTX 4090 Founders Edition did not support the NVLink bridge like the previous generation GeForce RTX 3090 Founders Edition. When people thought it was just disappearing on consumer products, the NVIDIA RTX 6000 Ada Generation released by NVIDIA didn’t seem to support NVLink bridges either.

According to TechPowerup, in the communication with the media, Mr. Jensen Huang, founder, and CEO of NVIDIA confirms that the Ada Lovelace architecture will not support NVLink seems to end any multi-GPU possibility and marks the complete demise of SLI via a dedicated physical interface.

Jensen Huang said that the reason for the cancellation of support for the NVLink bridge was that the I/O would be used for “something else,” so the decision was made not to waste resources on the NVLink interface. Nvidia engineers also want to make the most of the chip to “cram in as much AI processing as we could.” In NVIDIA’s view, PCIe 4.0 already provides enough bandwidth for today’s graphics cards, so there is no need to upgrade to PCIe 5.0, and the cache design of the Ada Lovelace architecture GPU also reduces the need for PCIe interface bandwidth.

In addition, Jensen Huang answered questions about EVGA in the Q&A session. You must know that EVGA is NVIDIA’s largest AIC in North America. It suddenly announced its withdrawal from the graphics card market before the release of the new generation of GeForce RTX 40 series, which caused a great response among the market and PC enthusiasts. Jensen Huang praised the other party as a very good partner and felt sad to see them leave the market.
