It's easy to see Nvidia as a gaming company, but it just isn't anymore. When it comes to AI, Nvidia is running rings around Intel, and AMD isn't even in contention for a lot of the markets that Nvidia is in. There is a reason why they have grown so much in recent years.
AMD fell far behind Nvidia, but hopefully things are on the way back up for them with RDNA 2. It seems to be a big architecture for them, and we will have to see how that goes for them. A 50% performance/watt bump is huge, especially without a new node. The question no is if it is enough.
As far as Nvidia goes, they are doubling down on AI and will start to push DLSS harder. Even if RDNA 2 is great, I don't think AMD has an answer to DLSS. That will be a big deal for them.
As you said, Nvidia is on a different scale to AMD in many ways, just like how Intel was with AMD. I just want to see AMD succeed, not because I am an AMD fan, but because we need competition to keep Nvidia's prices down and to keep engineers pushing every market forward. I also want to see Intel succeed in the GPU market for the same reason.
I think it became very clear today why Nvidia purchased Mellanox for $6.9 billion. They aren't a gaming company anymore, they are a gaming and datacenter company.
