Lol nice math there...
Compressed textures have been used for over a decade. PS4 and XBox One have freed up system memory to share for games as well. PS4 has up to 5.5 GB available for games with all the same tricks to reduce memory load. And that was cramped for 1080p. Native 4K requires 4 times the memory for most processing in the rendering pipeline. Is a 2.3x increase enough. My laptop is constrained by 14GB of use-able video ram at 1080p (6 + 8 shared from 16 total system ram) :/
Consoles have always been memory constrained, seems it will continue as usual.
PS1 -> 3MB ram (1MB video ram)
PS2 -> 36MB ram (4MB video ram)
PS3 -> 512MB ram (256MB video ram)
PS4 -> 8GB ram (4.5 + 1 GB on request video ram)
PS5 -> ?
Through the generations the increase in memory has actually been speeding up (12x, 14x, 16x) while launch games developers for ps4 already stated the memory was tight. So you see why a drop to doubling the memory raises questions. All the other things like better handling of textures, compression, faster memory is all the same.

You could at least try. 13gb is 2.6x 5gb. Gddr6 is like 2x more efficient than gddr5. So roughly a 5x increase. The rest stands: AMOUNT OF RAM MEMORY reached diminishing returns and will no longer increase exponentially.
Just look at the numbers. The 512mb the ps360 had 15 years ago was a lot. 5 years later top pcs were using like 4gb, moving on to 8. Now, a whooping 10 years later, we are still at 16-24gb. A much smaller increase.

How much is 4.5 + 1 ?
What does gddr6 is like 2x more efficient mean ? You can store twice as many bytes in 1 GB of gddr6 as opposed to 1 GB of gddr5?
Whatever you're trying to imply, every new gen had more efficient memory.
The 512mb was too little back then as well, remember skyrim on ps3...
16GB GDDR6 plus 8GB DDR4 would have been better and more future proof. Memory will be a bottleneck again, like always, but maybe even more now when the increase in resolution is the biggest between gens yet. 480p -> 720p -> 1080p -> 2160p At least the plans seem to be native 4K for next gen.
