It's a total load of nonsense. What differentiated the Titan class of cards from the rest of the cards wasn't a name, it was because they were prosumer cards which were aimed at people who wanted to do professional level work on them such as design, modeling and rendering, or any kind of GPGPU work, while also having a card capable of gaming. We KNOW this for a fact because the cards ship with 16-24Gb of vRAM on them where as games use a measly ~6Gb on average for 4k ultra. That extra memory was never ever useful for games, and if you're going to argue that point then just go read the "is 10Gb enough" thread to find out why you're probably wrong.
Plenty of reviewers this time around pointed out that the 3090 is NOT a gaming card, the performance gains of the GPU over the 3080 are very small, SLI is basically dead, and it's twice as expensive, so the only reason you'd buy it is either you have enough disposable income that price isn't a concern and you just want the best, or you're doing professional work on it.
Playing semantic games with words and names about what should be compared to what from gen to gen is just painfully stupid, it doesn't matter what the name is or what the marketing says, people with any brains don't buy things based on names, they review the specs and get what is appropriate for them.
