It's the PC baseline I'm talking about.
If the mass market can get away with having 4TF GPUs for too long then that means the prices of the higher powered parts wont come down as quickly due to the lack of demand for advancement and innovation. That's why we typically see the graphics cards that coincide with the final couple of years of a console generation being a piss take, both in terms of prices and in terms of performance increases (see the RTX 2XXX series). The demand for mid and higher end parts dries up as no AAA console ports are pushing the boundaries anymore, they are designed around hardware that PC gamers already had years ago. Going from 90fps to 105 fps makes no difference for most people and is not a reason to upgrade.
If the baseline is 10tf (which will be around where the 3060 will sit) then it means the 3060 will be a card in high demand. That will be recognised and then for the 4XXX series of cards Nvidia will have a huge incentive to create a low end 4050 that is 10tf and very affordable. The pricing and perfomance level has a direct impact on the rest of the 4XXX series lineup. The 4060 needs to be significantly better than 10TF, so on and so on. Everyone wins.
If 4TF is the baseline it will lead to both Nvidia and AMD taking the piss as the generation goes on. They already have cards that hit that performance benchmark at reasonable prices, they will simply keep on recycling those cards and the mid/high end of the market will suffer for pretty much a whole generation.
If you watch the Nvidia event from today, they make several references that make it clear they are putting these cards up against next gen consoles. IMO that is where the motivation for pricing the 3070 has come from at the moment. They want to make it clear you can have better than next gen console performance for under $500.
