[H] $1000 showdown. 6990+6970 v 580 SLI *56k warning*

In this apples-to-apples test we are using the playable settings on the AMD configuration, which is at 5760x1200 with the highest possible in-game settings. We see here that with those two extra features enabled, SSAO and Diffusion Depth of Field the performance absolutely tanks on the GTX 580 SLI. There is a whopping 93% performance difference favoring the AMD Radeon HD 6990+6970 CrossFireX configuration greatly.

For our apples-to-apples test we are running both configurations at 4X MSAA at 5760x1200 to see how these compare. The AMD setup is close to 30% faster than GTX 580 SLI in this game. The performance advantage in this game is night and day just like it was in DA2.

For our apples-to-apples test we are comparing at 5760x1200 with "Very High" settings and no MSAA. Just like the previous game, we are seeing about a 30% performance advantage with the AMD triple-GPU setup here. In this shader heavy game this is impressive to see.

What you are seeing in this apples-to-apples test is what we believe is a CPU limited scenario at these settings. This is the first time we have seen this situation with a 3.6GHz Core i7 since we have started testing with it at multi-display resolutions. When the AA setting is at a "low" 4X MSAA in this game, the triple-GPU AMD configuration just isn't stretching its legs. It isn't until you hit it with high levels of AA that its potential is fulfilled. So while this apples-to-apples test doesn't show much, our real-world gameplay tells another story, when you turn on advanced AA features that is where the AMD triple-GPU setup shines.



http://www.hardocp.com/images/articl...MicqqS_7_4.gif

We turned off AA and set both configurations to 5760x1200 with all Enthusiast settings. The graph speaks for itself, the triple-GPU AMD configuration is 25% faster than GTX 580 SLI



If you are fortunate enough to be considering a $1000 GPU buy, you surely want the best performance profile for your money and there is no beating AMD's Radeon HD 6990+6970 CrossFireX "TriFire." While not tested here today, Radeon HD 6970 TriFire would give you even better gaming performance should you have the room for it in your system.

At HardOCP we focus on giving you advice about value and getting you the most for your hard earned dollar. As enthusiasts ourselves, and gamers at heart, we have to suggest AMD's TriFire for providing the best gaming experience we have ever had. AMD TriFire has given us unrivaled gaming performance. Radeon HD 6990 + 6970 TriFire gives us 2GB of RAM per GPU so we can actually use the shader performance provided to improve image quality, and it gives us room to tinker and overclock for even more performance. AMD currently reigns king in the world of dual card gaming performance. Take a knee....again NVIDIA.

Everyone knows this >.<

And!

I'd still buy nvidia.

Yes, I did just say that

EDIT:

Not this thread again..... *sigh*

Isn't that 3 v 2?
post #4 of 175
No doubt about it AMD is doing very well this time around. I do think Nvidia cards have more overclocking potential just because they scale so well with clock speed. AMD owns them in price for performance currently though.

What's crazy is that they just had a sale on 480's for $230, which would only be $920 for 4!Much cheaper and I'm pretty sure quad SLI 480's would destroy both setups, but would also destroy your electric bill and take a beast power supply.

How can you compare a 3 GPU setup to 2 GPU setup...I don't see that as being fair at all...no wonder the ATI setup wins!

3 GPUs vs 2... zzzz

For the same price I'd like to see a tri-sli 480 setup vs. this.

I don't get the people who say this is unfair. Everything is comparable, and in this case, they've even chosen two setups that cost the same. It just shows, if you've got 1000$, the AMD setup will give you more performance. Simple as that ..

everyone stop complaining about how its 3vs2! as the title suggest they're trying to show which company gives u better value for a $1000.

blame nvidea for having expensive cards, because if not for that then maybe it would have been a fair 3vs3 with a 590+580 and 6990+6970!

Yes of course, and the reason for that is cause it's Tri-Crossfire Vs. Dual-SLI.

Now that's what I call win!
