different die, different prices and dev time, and whatever else so a comparison like that wont be accurate by a long shotDemand isn't growing though and was reported that GPU sales are at there lowest point for 20 years, Nvidia's gaming revenue is less than half of what it was a couple of years ago and thats with most the cards costing over double the MSRP from the previous gen when you look at the die sizes used. take a 4080 for example with an MSRP of $1200 while using a smaller die than a 3060ti and 16gb VRAM now costing less than 8gb did in 2021, Nvidia would have sold a 3060ti die and VRAM to board partners for less than $400 but you can bet that board partners are now paying significantly more for the 4080 die and VRAM, probably closer to $900.
as die sizes goes down price goes up a lot
