10GB vram enough for the 3080? Discuss..

It's actually been out for quite a while now, the problem is the lack of suitable hardware so devs can't crank it up (full path tracing etc.) outside of games like Quake II/Minecraft RTX's level of detail, it's why they focus on showing off RT reflections as it's the most visually obvious example of RT to the average joe.

Not necessarily, it depends on the type of game, those most likely to be affected are those with very large open environments where you can see many places at once, like FS2020.

So while you may not be bothered about reflections, if developers start using other RT features like GI/shadows then you may find an AMD card struggles, waiting for the 3080Ti may be a wise move atm.

It's more tricky than that. The long term trend is that vRAM demands increase over time for games, but so does their demands on the GPU itself. Once the demand on the GPU becomes too large your frame rate becomes unplayable you're forced to lower visual settings to get your frame rate to an acceptable level. As you lower visual settings to free up the GPU cycles, the demand on the vRAM also goes down. And you can spend that reclaimed vRAM on whatever you like, such as bigger texture pool.

So other settings except textures also use a decent amount of vram? I did not know that
I have never really owned a gaming rig before this is going to be my first

Despite this thread, NVIDIA is launching 3070 Ti with 10GB vram to replace 3080. Persistent arent they

Yea I heard about that, I was actually hoping for a 3070ti before march lol... that's when i buy.

I do wish it has 12gb vram or something that would be great, unlikely, but if it happens that would be great...

There is a rumooured 3060 12gb so i don't see how this **cant** happen.... Let's see.... Maybe we will get 2gb chips from micron and a 12gb/16gb variant of 3070 will be possible and 3080ti 20gb

Define decent?
When I last checked it can be around 50% for textures alone. (but that was in a combined memory pool could be higher when non gpu related items are removed from the total)

Depends how well the textures are compressed. Poorly compressed or uncompressed textures can be a real hog and offer no visible improvement in quality when gaming.

Oh yeah big time. The best thing to do to get a feel for this is to load up a game that has vRAM estimates in the video memory (Doom Eternal, RE3, FarCry5, CoD:CW etc) and then change the individual visual settings up and down and check the difference in estimated vRAM usage. There's often a significant swing if you switch from everything max to everything min. This tells you something important, games do not have a fixed amount of vRAM usage, it varies a lot depending on the settings you use. We can speculate about future games and their higher vRAM usage but we have to be careful when we do that, a game in 4-5 years time we could put in all low/min settings and the vRAM usage would be smaller than games maxed out today. So what we really mean when we say future games will be higher is specifically in a like-for-like comparison, which might be something like the game maxed out in Ultra at 4k now, vs a game in 4 years also maxed out in Ultra 4k.

My testing yesterday in CoD Cold War putting everything on min got me down to 2.7GB of estimated vRAM usage, although you cannot disable/uninstall the high res texture pack from the game menu you need to do it via battlenet or something daft, so I didn't bother with that. And then I maxed out the settings and it's about estimated 9GB of vRAM usage. The menu estimates aren't always that accurate but they'll give you a pretty close feel for it. Texture data is typically something like 1/3rd when everything is maxed.

Anyway newer games will put more demand on the GPU as we can see from the very latest games today you can't run in everything maxed out, not even with a 3090 which means you need to sacrifice some visual settings to get it playable, and when you do you free up vRAM.

Thanks for the explanation.

9gb usage? Wow... you were at 4k?

There isn't a lot of vram difference between 4k and 1440p right? Last I checked it was like 20-25% more vram usage

You should get a 6800XT once they are available for under £600 I recon. At least you would end up with peace of mind due to keeping the card long term.

That's ultra settings with all RT effects max at 4k with DLSS enabled and set to balanced mode. The 9GB is what it had estimated as the usage going by the visual settings vRAM bar, which is just an estimate. When I actually measured vRAM usage at these settings in game it was about 8GB max and less in some places. That vRAM slider in the menu is just an estimate so take it with a pinch of salt. But it's a quick way of getting a rough idea of what settings impact your vRAM and by how much.

At this point I doubt anyone cares about a 20gb 3080, unless the 10gb model is end of life and the 20gb replaces it for the exact same price

There are still a handful that think it will be worth it, even at the looney asking price it likely will be at. Though the vocal minority lately disappeared I noticed. I am sure they will crawl back out once a game comes out that really needs more than 10gb for maximum textures though :p

My 3080FE cost me under £600 in the end and unless Nvidia do a refresh of Ampere with Supers on 7nm, I likely won’t be too far of breaking even when I go to sell in in 18-24 months time :D
