XFX 7850... Is 1gb ok for 1280x1024?

[Chivpcgamer]

I'm done arguing.

ok dude, i didnt want to argue just was trying to get some clarity on the problem

[G.Freeman]

Its like my 580 has 1.5gb of ram ok, so if i wanted to play at 2560x1600 i get the 3gb version right? Wrong because the cards so slow at the resolution id be playing at low settings all the time. Sure the 3gb would help, but pointlessly so.

You are one of the few here that actually understand how Vram works. It's a miracle LOL. 3GB GTX 580 was a good idea if you put them in SLI though.

[G.Freeman]

then the OP can go through the thread and work out what percentage of people suggested what and draw a conclusion.

That's a flawed metric. The pros say that 1GB of Vram is just fine on HD 7850 but it's everyone else whom are not pros that say otherwise. They think just because the marketing says it true that is has to be.

Okay...I said I was done arguing, but I saw this, and it made me want to say this...I didn't mention marketing once. I mentioned Tomb Raider and Crysis 2 using more than 1GB of VRAM, and using Afterburner check my VRAM was above 1GB.

thats why i always regretted getting the 1.5gb version lol,

But that fact is that the extra Vram is pointless on a HD 7850 because it is to slow to use it. The difference between 1 and 2gb Vram @ 5760x1080 on HD 7850 is 4fps min and 12fps both are unplayable. The difference @ 1080p between 1GB and 2GB HD 7850 is 1fps in favor of the 1GB OCed version. http://www.bit-tech.net/hardware/graphics/2012/11/05/msi-radeon-hd-7850-1gb-review/3

You have SLI @ 5760x1080 rez ?

[Chivpcgamer]

You have SLI @ 5760x1080 rez ?

no but i would have by now if i had the 3gig cards lol

[Chivpcgamer]

To answer the ops question..... Yes it is enough just tweak things and youll be fine

[Chivpcgamer]

Using a weaker card too than the 7850. And TressFX hasn't been enabled numerous times, and it still consumed over 1GB of VRAM.

itll use more than 1gb vram if the card has more than 1gb. If not itll use the full 1gb and no extra. Itll put your card under load but as far as performance hit it entirely depends on what settings what game etc.

Compare an HD 7850 OC 1GB to my friends power color HD 7850 2GB @ 1050/1450 and play the following games

 

Battlefield 3, max settings 4AA+

Crysis 3 high/very high 2AA+

Metro Last Light high 2AA+

Skyrim Ultra no mods

Skyrim Ultra with mods

 

An HD 7850 is fully capable of running these above 30 fps, but in every scenario you will use more than 1GB and in some cases, more than 2GB.  The HD 7850 has the power to run these games at these settings, but the high texture resolution EATS up Vram very quicky as does AA.  Your 1GB card will give HALF the performance.

I play all of those games same settings as well on the 1GB hD 7850 no stutter above 30fps perfect. Performance is only negatively impacted at above 1080P resolution and then the framerate is so slow on both cards it's not playable.

Some people have their "un playable" fps higher that 30fps

Did you read the reviews and benchmark numbers of the HD 7850 1GB or did you skip them like some others and come here and try and debate your personal opinion against the pros that say you are wrong over at http://www.techradar...-1129390/review

"When it comes to gaming performance the XFX Radeon HD 7850 1GB Core Edition did better than expected with a screen resolution of 1920x1080! We were able to easily play all the current game titles at 1080p with the image quality settings cranked up!"  http://www.legitrevi...rticle/2048/13/

 

 

"in Battlefield 3 at 1,920 x 1,080, the MSI HD 7850 1GB was actually able to outperform the 2GB version thanks to its factory overclock, albeit by a single frame per second on the minimum frame rate. This suggests that the 2GB's extra 1GB of GDDR5 is all but useless at this resolution." http://www.bit-tech....0-1gb-review/10

 

"We have to admit this was a bit of a surprise. We wanted to get the 1GB version of the HD 7850 to test it against the HD 7770 more than anything else - assuming this would be the card it'd be going up against. After all, the 2GB frame buffer of the stock HD 7850 must be partly responsible for its impressive showing at hi-res, right? And that's putting post-processing such as anti-aliasing in the mix.

How wrong we were. It seems that the bottleneck to the Pitcairn Pro's performance is not the memory at all - the GPU itself bottlenecks performance well before the memory gets anywhere near making things crawl.

What does that mean though? Well, it means the 1GB version of the HD 7850, especially the slightly overclocked version supplied by MSI, is more than able to keep pace with the stock 2GB version of the Pitcairn Pro card." http://www.techradar...-1129390/review

Well you are the one whom needs to chill. Back up your opinion when someone else has shown you to be wrong otherwise it's no good to be spreading misinformation and flat out untrue info.

[PCBudgetSolutions]

All of those were from 2012 before the big 12.11 drivers and current 13.4 drivers. Also note that the minimum fps is a lot lower on the 1GB versions due to frame buffer bottleneck.  Should look at links before you post them.  Also the newest game I see is battlefield 3 and they aren't even playing online to stress test the high texture resolution in high intensity areas.  That's why 1GB @ faster clocks is prevailing.  Try Crysis 3, metro last light or BF4 and see what 1GB does for you.  Even modded skyrim will bottleneck a 1GB video card.

Only at 2560x1440P and above however at 1080P the only game tested that the 1GB card did worse was Skyrim and even then it was still completely playable.

I'm just going to close this as it is in no way productive.
