Xioros's VRAM usage guide & discussion - Page 8

post #71 of 81
Having 2x 680s my experience on current games are quite literally showing me that VRAM would extend the length of my cards. SLI has brought me (with decent scaling) more than 780 levels of performance and yet with each card only having 2GB of VRAM I am now limited to medium/high textures in quite a number of recent games, starting with Titanfall to todays Shadow of Mordor. I am also hitting the VRAM cliff on some graphical fidelity settings as well especially with the ultra lighting settings.

So for me what is happening is I can turn down the graphics so that it fits within the VRAM limits and I am then getting a frame rate in and around 60-90 fps depending on the game. Since I have a ROG Swift with Gsync that is a pretty smooth gameplay experience and I tend to prefer >60 anyway so it sort of works out. But I also think SLI changes things, you put yourself into the next generation of performance but with even less VRAM (because the mirroring takes some VRAM to do) than the generation the card is in. So that biases some games into high frame rates as you can't utilise the additional performance any other way.

But if it was a single 680 then the VRAM would be basically right for the power of the card. It wouldn't suddenly be struggling just because of VRAM, it would be struggling with compute performance as well on a lot of these settings. Maybe in one game you might be able to get the textures +1 setting if you had 4GB but over its life it wouldn't have paid off very well considering the extra cost. But for SLI I wouldn't be seriously considering switching cards just because of VRAM concerns that I am actually having.

So when we translate this to the 780 I think we are in the same position. A single card more or less handles the games and their settings about where it should. If you had 2x 780's you would be bit limited right now, occasionally finding that you had a bias towards more frames because you couldn't actually utilise it well enough because sometimes you hit the VRAM cliff. In a year or twos time it would probably look a lot like the situation I have with the 680s. You would have 16nm card levels of performance and yet unable to set some settings to high in a number of big games because the usage of VRAM was just too high.

There is a reason for why it works this way. The way you right software like a game is you write it to what the market actually has available. If you write the software such that it runs on some future computer that doesn't currently exist no one will buy it and no one can run it. The developers can't even test it because they don't have the hardware. So when we look at what is being produced we can be certain that games will come out targeting particular hardware. They will target what the market owns already and what they can buy and basically what they have in the office to test with. So some of the console developers will make games that run very well with moderate compute performance and utilising up to 5GB VRAM at 1080p. Its much more likely however that the games out on PC will be a bit more balanced, biases towards 780's, 290's and such with their top settings. The titan the 290X2, SLI etc do make up a very small amount of the market and while many will try to get their games working well with that hardware its relatively unlikely it will be the target of their top settings.

The counter I have to this chain of thought however is that there is always going to be games like Crysis. They can't be run on todays hardware, and its either because they targeted something in the future that didn't actually arrive in time or they wrote the game really badly and it doesn't run very well anyway. Seems to be a lot of the latter going around and the approach on PC has always been to just keep progressing the hardware every year so that the problem goes away. Its quicker and cheaper for developers to allow Moores law to eat up any inefficiencies in their design of software.

What I know is that 2x 680s do not have enough VRAM today, they are starved of it. A single 680 isn't, its got a reasonable balance of compute to VRAM capacity and bandwidth and that is no surprise because its a level of hardware that developers target because its real hardware that exists and they write software to run on hardware that exists.

Is this discussion limited to nvidia cards only? I can contribute some vram usage numbers for extremely high resolutions but I only have AMD GPUs right now.

Nope, it's GPUs in general.

It just happens that I found clear comparisons for Nvidia cards.

If you have numbers for your AMD cards, feel free to share! thumb.gif

Info post updated. It could use some more hard numbers, so if you can send some benchmarks: please do so.

More info needed on:
How does filled VRAM size (and clockspeed) affect frame minimum fps & frametimes? We know that better system RAM affects the minimum fps (and even average FPS to a significant degree)

Is there anyone with a high VRAM card 6GB+ that would be so kind to do some test runs with different settings of MSAA? (none, 2X, 4x, 8x, 16x. Paired with VRAM usage numbers).

This applies to both AMD & Nvidia.

This applies to both AMD & Nvidia.

To answer the question about how to tell if vRAM is full. Only sure way in my experience is the frame rate taking the step off a cliff. On a platform with dual channel ram the resulting fps is about 3.. 4 fps (AMD 1055T) and on a platfrom with quad channel ram its about 7.. 8 fps (i7-3820). GPU-z number are not accurate as it tends to seriously overestimate the vRAM usage in my experience. My guess is that it shows also cached stuff as in-use vRAM. To draw a windows memory manager analogy as an example:

In that image the green part is the amount of RAM actually in use, the dark blue part is in essence free RAM but as its not in use at the time it's used as a cache by the system (prefetch and last accessed stuff from the disks) and light blue is the truly unused memory not used for anything at all. I believe GPU-z reports basically green + dark blue bars as vRAM usage. While in reality one has a lot of headroom before stuff gets tense memory wise.

This observation is based on years of running relatively high resolution setups on a relatively modest GFX hardware. The setups I have used in the past are:
AMD 5770 [1 GB] Eyefinity 3x 1080p ~6 megapixels
AMD 6770 + 5770 crossfire [1 GB] Eyefinity 5x 1080p ~10 megapixels
AMD 6770 [1 GB] Eyefinity 5x 1080p ~10 megapixels
AMD 7870 [2 GB] Eyefinity 5x 1080p ~10 megapixels and 4k ~ 8 megapixels
AMD 7950 [3 GB] Eyefinity 5x 1080p ~10 megapixels and 4k ~ 8 megapixels
AMD 390X [8 GB] Eyefinity 5x 1080p ~10 megapixels and 4k ~ 8 megapixels

With AA off it's possible to drag 1 GB as far as 4k resolution (or 4x 1080p eyefinity) (Crysis 1, Metro Last Light in DX 9 mode, etc) although even then it's possible to hit vRAM wall if not very careful with settings. However, with only 1 GB its better to stick to up to 3x 1080p eyefinity at most. No idea how the more moder titles act, they might be a lot more liberal with vRAM nowadays but then again cards with 1 GB are not all that common anymore anyway. With 2 GB of vRAM 4k resolution is fine with AA off with only rare hits to vRAM wall (heaviliy modded Skyrim, Crysis 2, for example). With 3 GB of vRAM I did not manage to hit the vRAM wall ever with AA off in the titles I own (about 400 games in Steam library although TBH I have not exactly tested them all, or even played them all).

I'd love to benchmark both 2gb and 4gb versions of the 960 and see if paying 10-20% extra is justified. I currently game at 1440p with the 2gb model and I am a bit surprised to notice no VRAM bottlenecks even in modern titles (GTA V)on maxed textures. Of course I do have to lower other settings to make games run 60+ minimums but I'm not disappointed in any way.

Interesting test by TPU

VRAM usage on a Titan X 12GB:

Quote:
Using a GTX Titan X, which has 12 GB of VRAM, we tested the game's memory usage. As you can see, the game always uses 6-7 GB of VRAM. This may sound shocking at first, but in reality, the game runs very well with cards that don't have as much memory - look at the performance charts. It seems as though Crystal Dynamics' engine will happily use as much VRAM as it can, but is very well optimized to make do with much less without sacrificing framerates.

Look at the difference between a R9-Fury 4GB and R9-390X 8GB




The Fury and R9-390 both scale linear with resolution and are not bottlenecked by VRAM in any way.
