How much vram do you actually need?

So would a 780 be a better choice over a 4GB 770? I'm just wondering because I'm having problems deciding between the two.

 

you're just comparing poorly if you're letting vram decide between a GK110 vs a GK104

 

get the 780

Coming from an actual owner of GK110, 4GB 770 SLI!

At max settings, BF3 uses 1.5GB of VRAM. This is at a resolution of 1600x900

Basically this.

 

Even the Titan doesn't benefit from having 6GB of VRAM. (Example:  Dirt Showdown uses 1839mb at 3840 x 2160, and is completely unplayable.)

 

All of this crazy amounts of RAM is just marketing.  Anything over 2-3GB for a single GPU right now = wasted.  Now AND in the future.

i agree with this until it said "now AND in the future."  that's something rediculous to say. some people still run computers from the 90s, bet they thought those 20gb hdd's were enough back then. you can't predcit the future so dont act like you can lmao!

They will still be the same video cards. I wasn't referring to future cards, but current cards with that amount of VRAM.

If X card with Y VRAM can't fully utilize that VRAM now because it is not powerful enough, that will not change in the future. Hence, what I stated holds true. Which is why I stated ''single GPU right now". I am pretty certain I didn't try to predict then future.

 

You've just compared a video card to a hard drive, seriously? Also, a spell check wouldn't hurt. I am assuming a lack of reading comprehension

O.o dude a 7850 is not that weak.... plus PC games always increase to scale with console games, so when Console games got 512MB VRAM we got a lot more, look at the Xbox 360's release date an the difference between that and a PC.

You do understand most console games run sub-720p resolution.

With PCs most people are pushing 2-4x the pixel amount at much higher graphic fidelity.

 

You could still play PC games at console resolution and equivalent graphical settings on a 8800GT and most likely still run it better then the consoles.

 

The Xbox 360 launch vs PCs at that release date was an anomaly, it was very advanced for its time. This next gen of consoles not so much however.

 

You're most likely safe with 2GB VRAM and be comparable to the consoles for the generation.

 

Battlefield 4 developers said the console graphics for the game are comparable to medium on PC. The recommended specs list a GTX 660. Minimum was a 8800GT I believe.

 

I'd go as far as saying console optimization is a myth, the difference is in the quality of the port.

xD so you're sayingg that the similarities between hardware and the fact that deelopers have even said that they're going to optimise their games more (Planetside 2 e.g.) is a myth? This conversation is over.....

>How much vram do you actually need?

 

Depends on your screen res and what you do... For me, 1GB lags my system if I'm doing something intense. For someone else, 1GB of vram is perfectly usable.

Hi there.

 

If you gonna play triple screen then I would recommend you 770 SLI.

 

If you gonna play single screen I think 780 would be nice.

 

I bought 780 SLI and now I'm starting to think that I´ll be vRAM capped very soon. I´m at 3 x 1440p.

 

Right now I think Titan SLI had been the better choice in my case. I didn't think 1440p was that different from 1080p.

 

The recommend settings in BF4 is 3GB of vRAM BTW.

 

Read you guys!!

what is the most vram a single has ever had? was it the 6gb stuff or is there more?

 

also with sli/CF solutions does the vram add up?

#edit#

Q2 does the vram add up on two identical card only or does it add up on two separate ones eg: 7XXX 1gb and 7XXX 2gb ?????????

i only have a single 7770 so i dont know

My 780 uses 1.3GB in Far Cry 3 without AA, everything else max @ 2560x1440.

The vram is not additive to a total. Two 1GB cards does not equal 2GB of Vram. It is 1GB of frame buffer for each card, and still performs as 1GB in totality.

Some say 2gb will be needed for upcoming future games if you want to play them on max settings, but we shall see when the actually come out.

If you're buying a card now and you have a 1080p or higher resolution monitor then I wouldn't consider anything less than 2GB VRAM. If you have a lower resolution than 1080p then you could get away with 1GB VRAM but I'd still aim for 2GB if you want to turn on your eye candy.

Should 1GB hd7770 be enough for 720p gaming,for probably next 1-2 year?  720p res,medium/high settings,no AA.

I definitely felt the bottleneck of the 1GB of vRam on my old X-fire 5870 setup when gaming...

 

While rendering they destroyed everything(even my modern X-fire 6970 setup). But under heavy game loads or anything with mods they tanked...

 

My 6970's now even sometimes bogg down if I have too many mods installed on say Skyrim.

 

I would say to be relevant in today's gaming market you need at least 1.5gbs. (My old 480 for example was an awesome and still is an awesome card)

 

Yes you could get by with an X770 card or X60 with 1gb but, if you want anything above 720P I would get the extra wiggle room.

Just my little input.

 

If you have a graphics card with enough compute power to run games on max settings (max as in everything on Ultra, Full shadow, 8X MSAA, 16X AF, HBAO, all the good stuff), why the hell not?
Why would you turn MSAA down to 2x if you are not VRAM limited?

It'd be disappointing if...say a GTX 780 only had 1.5GB of VRAM. Thankfully, this isn't the case.

I think with upcoming consoles we will be seeing our pc hardware pushed very hard in th near future. Look at COD requires 50 GB I bet a lot of that is going to be high res texture which can gobble up the VRAMS. My modded skyrim has seen 2.6 GB usage on my card before.

What about gaming at 5760x1080? I know not many of you guys do or intend on gaming at such a resolution for your own personal reasons, however i intend on giving it a shot. 3GB vram to me at that resolution with  AA doesn't seem like it will be enough for me in the long run and most likely may not be enough for some games of this generation already. So  how much would i need in this case?
