Then why hasn't Nvidia bailed on gamers already if it's such a waste of their time?
Misinterpret my point. I don't believe Nvidia going to ever leave the gaming market or stop putting RD&T. What I am saying is that they will focus on features that can be used in more none gaming GPU also and if that mean they price out a lot of people they not that concerned. They more interested in selling the most powerful GPU to enthusiast then designing a GPU for the masses.
This always been the case but starting with Kepler they was very focus on the mobile market as you see with all the shield devices they launched which meant a focus on energy efficiently and the GPU architectures they released show that. This happen to work out well for gamers and pricing.
By the time the 20 series release there focus shifted too AI and therefore there gaming GPU also reflected that. I actually agree ray-traying was more of a well we spent all this RD&T on AI focus stuff how can we also make use of it for gamers. The fact that packing all this AI stuff into the GPU was going to increase cost of there GPU was not something they concerned with.
You can also see this with the 30/40 series in that they know the most units they sell is usually the xx60 lines and in previous generation they release that 2-4 months within the flagship. In 30 series it was a entire year and 40 series we still waiting on.
I just don't believe Nvidia cares if people not willing to pay $600+ for a GPU stop buying there discrete GPU if the architecture requirements for there AI GPU is expensive that going to reflect in there gaming GPU prices.
They not going to make 2 completely different architectures so the data center and gaming one going to share a lot of stuff and the focus always going to be on what make the most money.
