NVIDIA doesn’t separate their networking revenue, but at time of acquisition mellanox had less than a billion dollars on sales. Less a half a percent of NVIDIA’s current data center sales. That has undoubtedly grown, but I would be surprised if the networking share of their data center business was more than a rounding error. Keep in mind they sell GPUs for $50k, 2-8GPUs per box, and even a state of the art Infiniband card to put in that machine is only a few thousand bucks.
