Why NOT to get the 760/770 4GB

[nokturrduk84]

Linus should investigate this

We'll see about this...

Does this call for a tech quickie?

Memory bus, speed, and capacity

No, this calls for me to go mod a game and get my 760 using more than 2GB of VRAM.

Alright, let's see.. It may use around 2-2.5 but it won't go higher than that.

Interesting... Then why they made 4gb versions of those cards?

for people, that don't research there cards and Just think more is better

It seems there's no difference between them

[ManOfDisguise]

if what OP is saying is true, then I'm glad I got the 2GB version

Yep, there's no need to get 4gb version, as you see there is difference only 1-2 fps

all within margin of error because the games treat both cards as 2gb models since it cannot use the extra 2GB effectively since it needs to be able to access all of it at the same time.

yea... is a hiding rule... but is a rule for us  B)

 

but we don't talk of that, is tabu lol 

 

 

 

128b x 1GB = full use

I don't know what to do now =( I was planning on getting a GTX 770 4GB for my surround setup, but with this info I don't know how. I want a Nvidia card for Shadowplay reasons, but I can't afford a 780. Should I just go for a 2GB version? I currently have a GTX 650 2GB and it doesn't take up all the VRAM when I run games in surround, soo.....

You know ShadowPlay cannot capture your surround footage (to my knowledge)? You need to be playing at 1080p which is why I couldn't record when I was at 1600p. I need to test this though so don't quote me.

My epic paint skills, now if the bus is smaller the memory needs to be faster to cope with the Bus size bottle neck. Ignore the "but bus" spelling mistake. :')

But when there is so much data going through a small bus, you'll see the 4GB slowing down exponentially, so there isn't any point in getting the 4GB version. R9 series all have giant buses that can actually use all the VRAM

well ive seen a 2gb stutter in skyrim with the same mods as me and my 4gb doesnt and with the mem clock being so high and the 4gigs its about the same as having a a 280x with 3 gigs so it really doesnt matter its worth it to alot of people id rather have a card thats not going to run out of memory anytime soon than one that is already a basic amount that WILL stutter in some cases. take this from someone who actually owns a 4gb 770.

I wasn't planning on recording in surround anyways I know it can only handle 1920x1080.

That picture sums it up just about right.

Correct me if I'm wrong, more VRAM = less stutter.

wrong look at the benchmarks for the GT 640 4gb, its garbage.

[biohazard918]

Those 4gb 760s and 270x's are for crossfire and sli where you are running at high resolutions like 1080p triple monitor setups  the idea that they can't some how can't access that much ram is bull shit the 128bit memory bus on my cpu can handle 32gb the wider memory buses on higher end cards is for increased bandwidth you also see large amounts of ram on professional cards like the K6000 that has 12gb. The only real difference between the memory controller on a cpu and a gpu is the use of ddr3 vs gddr5 512 bit memory bus is really 8 64bit controllers. If you were to say run 3 way 760 sli at 4k then the 4gb of ram would be a worthwhile investment.

the gt 640 4gb is a stupid pointless card its benchmarks are garbage because its garbage your compairing 4gb of ddr3 on a low end crap card to a 760 with 4gb gddr5 which is pretty much intended for people who plan to run sli.

I respectfully disagree with most of the stuff you said. The bus is too small, so when you are gaming with 3 monitors, the FPS will drop because the bus would have so much data flowing through such a small area that it ruins gameplay.

 

I have no idea what you mean by 128 bit on a CPU, and handling 32gb......no idea what you are talking about there.

 

3 760sli at 4K, that's stupid. The cards cannot handle 4GB worth of textures, with only a 256 bit bus, thats silly.... That's like trying to get 500 people in a 250 person airplane
