Crossfire vs SLI - 280X/280/270X/7850 vs 770/760/660/650 Ti Boost

[DGLee]

About a month ago, I posted the article <Crossfire vs SLI : Flagship Gang Fight> which tested 4 flagship VGAs from two major manufacturer, AMD and NVIDIA - R9 290X, R9 290, GTX 780 Ti and GTX 780 with single, dual, triple and quad Crossfire / SLI configurations. If we could ignore the issues come along with CF such as microstuttering OR if the issues were ignoreably small, then there is a clear way forward us : CFing Radeons benefits more than SLIing GeForces not only in terms of scalability but also in terms of absolute frame per second. 4x R9 290 actually faster than 4 x GTX 780 Ti in several cases I tested, indeed, even 3 x R9 290X bests more numerous configuration of its rivals more than a couple of fights.

At this moment, what we should remind is, however, digits in our bank account. It's obvious that a R9 290 is very attractive combination of sexy performance and affordability yet we are already aware of the absolute fact that everything is relative. R9 290's affordability could only be derived by comparing it with GTX 780 or GTX 780 Ti, not R9 280X nor GTX 770. How about CF/SLIing a pair of R9 280X or GTX 770 then? Could they be more affordable way to taste TITAN-class performance? That's why I planned this spin-off.

Here are result analysis part.

(I apologize that I cannot even try to upload the entire images due to traffic issues, because they are so many. You may see the whole results from my blog: http://udteam.tistory.com/604[/URL])

Here are the scalability analysis part.

Thanks for reading

Excellent work!

Wow! Thanks for taking the time to put that together.

If you have the time, could you add in the Xfire/SLI results from the high-end cards? I'd be curious to see them all on the same chart.

Thanks DGLee.

Btw your link in the first post is not working.

Well thanks OP, but this just smacks of a PR spin

Power is nothing without control.....
edit-pretty graphs though

uh, I think his point was that if we could ignore those issues then the numbers speak for themselves but he's saying we can't ignore them. How is that PR spin?

If anyone is interested, heres a link to his original post with the big guns.

No he is not....he is saying ignore the issues, CF has the better RAW power....

No your reading it wrong.

Is like simian says.

What drivers and what settings were used?

http://udteam.tistory.com/604 <----Correct link.

http://cfile5.uf.tistory.com/original/224E094852CDC7F1020F7F <---System specs.

 

[Carfax83]

Some of those benchmarks don't look right to me, particularly the BF3 and BF4 benches.

Go look at other review sites about BF4 and BF3.

Remember BF4 is an amd optimised game. And BF3 is also frostbite, i can see some optimasation from BF4 bleeding over to BF3.

Here's a review of a 290X that some some graphs including a Ti.

hello
a simple question

i have a sapphire DUAL-X R9 270X 2GB OC WITH BOOST and i'm kind of planning to buy another 270X......but this i'm thinking of buying sapphire TOXIC R9 270X 2GB WITH BOOST or VAPOR R9 270X OC WITH BOOST..

can i crossfire my SAPPHIRE DUAL -X R9 270X 2GB OC WITH BOOST with any of these two card??

thnx in advance

 

[guskline]

DGLee, thank you for all the work. That must have taken some time. What were the specs for the rest of the test bed?

 

[SlowSpyder]

Awesome work OP, thanks for sharing the results of your testing. Good stuff!
