Does more vram really make a graphics card more "future-proof"?

post #1 of 7
Thread Starter 
I heard this said a few times, that having more vram on your graphics card will make it more future-proof, but not by anyone I can be sure knows what they are really talking about. I've also never seen any proof of this. So do you guys think having more vram on your graphics card really make it more future-proof and, if so, what proof can you point to in support of this?

E.g. if you think back to the last generation of cards, were there any cards which turned out to have a longer life than similarly powerful cards of the same generation, simply because they had more vram?

Well, any card with more of anything will last longer in the long run. Is Vram more important than clock speed, for example? maybe. Is it the most important longevity item on a graphics card? Really depends. The more Vram you have, the higher you can set your resolution, textures and anti-aliasing; things that have really come a long way from before. resolutions in desktop computers have increased from 1280x1024 to 1920x1080, thats a lot more pixels. Texture sizes have increased at least threefold and anti aliasing is at crazy levels now. I have a feeling that people said that because of how important it was, not is. Just like having 16g of RAM today is a little too much for regular gaming, I think having 8g of Vram is a little over the top, too.

Lol, maybe you will need 6gb of vram on a single monitor when games start using resolution textures that is 4 times the resolution of todays.

as long as u have the gpu power (and the cpu to feed the gpu) i'd say so

Wait until 4K resolution monitors become the norm. GPU will probably need 8GB Vram to run those high resolutions.

This is where I based my assumption. You should read his blog (?) its really interesting. Anyway, I don't think 4k display resolutions are going to become the norm for some time now. biggrin.gif

It depends entirely on the resolution and DirectX level you're playing in. DX9 and DX10 are not that bad when it comes to Vram hogs. That being said though, DX11 is known for it's ability to require ample amounts of Vram. So having the excessive 2-3GB of Vram on your GPU isn't entirely a bad thing. It's only really bad if your GPU isn't fast enough.

For instance, I've seen a 768MB GTX 460 lag at the same settings that I run AvP with my 1.5GB GTX 460M. My GPU is considerably slower, roughly half as fast. However the lag is induced by the lack of Vram on the faster card. My framebuffer is double that on the desktop model. I've seen my card using 1.2GB of Vram and running smoothly at high settings, no AA, with a constant 60 fps. Whereas the same settings for the desktop card were barely managing 45 fps constantly.

So there IS a method to the madness in some cases. Yet this doesn't go off unchallenged by logic. I mean, a 2GB GT 430 is no faster or better than a 1GB GT 430. Primarily due to the lack of power the core and shaders have.

To summarize this, you won't need more than 1.5GB of Vram for Nvidia Surround/Eyefinity for a DX9/10 game. However a DX11 game will require at LEAST a 2-3GB framebuffer for the same setup.
