After Nvidia released the Ada Lovelace architecture GPU, many people found that the GeForce RTX 4090 Founders Edition no longer supports NVLink bridges like the previous generation of GeForce RTX 3090 Founders Edition. When people thought it was just disappearing on the consumer side, the NVIDIA RTX 6000 Ada Generation later released by NVIDIA also doesn't seem to support NVLink bridges.
According to TechPowerup, Mr. Huang Renxun , founder and CEO of Nvidia, confirmed in communication with the media that the Ada Lovelace architecture will not support NVLink, which seems to end the possibility of any multi-GPUs and marks that SLI implemented through a dedicated physical interface has completely disappeared.
Huang Renxun said that the cancellation of support for NVLink bridges is because I/O will be used for "other purposes", so he decided not to waste resources and leave NVLink interfaces. Nvidia engineers also want to make the most of the chips to "add as much AI processing as possible." In Nvidia's view, PCIe 4.0 already provides sufficient bandwidth for today's graphics cards, so there is no need to upgrade to PCIe 5.0. At the same time, the cache design of Ada Lovelace architecture GPUs also reduces the demand for PCIe interface bandwidth.
In addition, Huang Renxun also answered questions about EVGA in the Q&A session. You should 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 in the market and PC enthusiasts.
Huang Renxun praised the other party for being a very good partner and felt sad to see them leave the market. He said that the CEO of EVGA has wanted to end the graphics card business for several years and will miss them forever. It is an important part of NVIDIA's history and believes that now is the time for Andrew Han to do other things.
