Yep. Problems is, they are all being priced by and for Americans on 6-figure salaries, or people like NVidia boss on millions in bank.
For rest of world on low 5-figure salaries, they are just stupid prices.
Anyway, does anyone know if this kind of memory bandwidth is now limited by PCI-E 3 and can now benefit from increased bandwidth of PCI-E 4 as used in latest AMD X570 ?
Generally speaking, gaming consoles have the equivalent of a mid-range PC graphics card. For this coming generation, that means RTX 3060 / RX 6600 level most likely. Xbox Series X seems like it will land a bit higher up the tree (52 CUs should be high-end), but the top PC parts have always been a big step up in pricing for modest increases in performance.
RTX 3090, like the Titan cards, is not really meant to be a popular card. It's a tour de force from Nvidia, to maintain its lead as the fastest overall GPU. Because there's a lot of marketing value in being able to say you make the fastest graphics card. People might not be able to afford it, but they'll be more likely to buy the second or third tier GPU from the leader.
As for memory bandwidth, it has the opposite effect in regards to PCIe bandwidth. The more memory and memory bandwidth a card has, the less the PCIe bus matters. Right now, theoretically a card could load all the texture and world data into its VRAM in less than a second, and then not have to worry about PCIe bandwidth -- only 'new' data needs to go over the PCIe bus. Even PCIe Gen2 can mostly keep up with the draw calls and other stuff that keeps getting sent over the PCIe bus. But being PCIe Gen4 definitely won't hurt performance on the new Ampere and Navi 2x cards if you have an appropriate platform.
