2x 3 GB HD Radeon 7970 vs 6 GB HD Radeon 7970

[Rakoooh]

hi there 

 

Hey i have rather simple question, but I need more confirmation about my knowledge. I want upgrade my graphic card. Right now I have sapphire Radeon 3 GB hd 7970. So would a double sapphire radeon hd 7970 in crossfire equal one ARES2-6GD5 ? 

 

If they have the same performance or small difference, what are the advantage of have double Graphic card? will the single card use less power? 

 

well that's for now, I hope I get helpful information from you guys

 

THANKS ! :)

They would match it slightly but the ares is clocked alot higher

The extra Vram is useless unless running 5760x1080P triple monitor resolutions. The Ares is an overpriced piece o crap imo get another 7970.

The ares 2 is two hd 7970 ghz edition in crossfire, watercooled naturally : ) you wont be far off with two hd 7870s in crossfire, depending on your pcie lanes. As far as memory the ares 2 can only use 3gbs of memory so its not really 6gbs as such. The ares 2 will overclock very well also so its a bit hard to reach its performance without overclocking your cards fairly heavily : )

LOLL it's a hacked in all in one CPU water cooling loop. It's a sub par cooler that doesn't even have the power to cooler the VRM you need an additional tiny fan that sound s high pitched it hurts the ears LOL.

dont laugh at my comments, i said its watercooled and it is. Yes its a dual gpu on one pcb im not stupid

[vkadurin]

There are only 1000 Ares IIs produced so it is very difficult to find one. It is collectors' item though and i would have it just for that reason. But in the real world - just get another 7970 :)

No no I am not laughing at your comments I am loling about the hacked in sorry little low performance silly excuse for a liquid cooling loop that can't even cool the 7970x2 without the assistance of a tiny high rpm noise maker fan. So much for the silent metric that erroneously surrounds liquid cooling loops.

ok thats fine then, all watercooling needs fans, i personally think its a cool piece of equipment but probably would get another 7970 instead of it

The ARES II is faster than two 7970 GHz edition cards in crossfire, but not by much & it only has 3GB per GPU of effective memory.
So essentially you will have the same sort of performance with a second 7970 Ghz edition.

exactly, im not sure if the watercooling will help overclocking? I have seen some huge benchmarks. I imagine theres no need to overclock it lol its a beast

Might as well of just air cooled it I mean it nothing more than a look at me type I got water cooling stunt thing.

[Chivpcgamer]

Watercooling definately gets better results than air cooling but i really dont want a debate lol : )

Well the liquid cooling will help keep the card running at reasonable sound levels once an overclock has been applied, other than that I don't think that it's necessary, especially after seeing how fast & quiet the reference 7990 is.

remember though its 2 ghz editions plus overclocking headroom. Hang on is 7990 two ghz editions too?

Yes, well sort of, two Tahiti cores each clocked at 1000mhz.

you make a fair point then, although if i was rich id buy it because it looks ace! : )

They are Tahiti XT2 cores in the Ares2 but if you can get some 7970 GHZ Edition XT2 cards in CF is will have better cooling and OCing potential.

i might look into those myself, how would you rate 7970 crossfire?

Not bad but I guess there is some issues people are talking about. I never had any issues with CF except massive boosts in performance in every game I was playing at the time. Aside from performance boost with CF you get image enhancement boosts with new AA options available.

Haters gonna hate!...

 

To answer you question there are 2 options...

 

The ARES2 is somewhat faster, but you will not notice this, it is also on one PCB making it more power efficient, but it is quiet expensive.

 

The 2x 7970 will be alot cheaper, but you will expect some problems due to CrossFire.

 

IMO if you are a AMD fanboy and have the money upgrade to the ARES.

Inconsistent frames is the issue with Crossfire currently.

Never had the problem.

great answer, only point i would make is that ares 2 is still in crossfire unless im mistaken
