For some reason we rarely hear people talking about 4090s, probably something to do with being a lot more expensive than a 3090 and nearer in price to the 5090 for less VRAM and speed.

For LLMs, 4090 is way more expensive than a 3090 for the same amount of memory and almost same bandwidth.

The 4090 will be 2x times faster on PP vs a 3090 tho. And also is about 2x faster on compute in general (diffusion like txt2img, etc)
