I got a question if you dont mind.
But what would bottleneck a gpu more when talking vram, its final bandwidth or it the amount of vram?
Obviously we want faster and more, but wich to prioritize?

You need to balance the two.
If you don't have enough Graphics Ram, the GPU will be requesting data from system memory and if the data isn't in system memory it will request it from the SSD or Hard drive and you will thus have a corresponding hit to performance, the Geforce 1060 with 3GB of memory is the perfect example of this.
But if you have tons of slow memory, then you are holding back the fillrate, the Geforce 1030 DDR4 is the perfect example of this as well.
Obviously the more bandwidth or the more memory you provide the higher the bill of materials.

I was mainly asking because of the 3070 and 3080 have the same amount but different bandwidth's. So im not sure if the 3080 would reach some kind of limit in some cases, where the 3070 would not as it would get there anyways.

The 3070 has 8GB @512GB/s of bandwidth.
The 3080 has 10GB @720GB/s of bandwidth.
There is one thing we need to keep in mind here though... The 3070 has 47.8% less functional units than the 3080, so it's bandwidth and memory needs are also that much less.
The higher the resolution you game at, generally the more video memory and bandwidth you want as well so you can keep all that data stored locally on the GPU.

Well I got the vram amount wrong of the 3080 so that blows my question out the water.
But that helps understand better, Since I only saw the amount as the marketing thing I just always thought throw more at it and you compensate but they hit different bottlenecks.
Thanks anyways and @CGI-Quality Not a pc gamer it was just for personal knowledge.
