Default Re: Battle of the Giants: 5970 CrossfireX vs. 480 Tri-SLI

1920 rez benchmarks of tri and quad cards...thats just silly.
Why would anyone do this on anything but 2560 etc.

Between this and the 3.4ghz CPU the whole thing is useless, really. Just two 480's are limited in many cases with a i7 clocked that low, I can only imagine how much of a bottleneck that would be for three of them or Quadfire.

Nah, it's not that bad. i7 scales much better with multi-GPU than the Core 2s do.

They should've OC'd it more, though, without a doubt. I don't understand why they didn't. They did say that they ran one game w/ the chip OC'd to 4.4GHz and didn't see much gain, but that was just one title. Could've been different on the others which is one reason I think Quadfire didn't come out ahead in most of the benches. Takes more CPU power than any of the rest.

Not a very thorough comparison IMO. The framerates shown in the first post are in general quite high, so even a single GPU is not getting stressed in most situations. Also, the fact that there is relatively little gain from SLI to Tri-SLI on the GTX 480 either indicates CPU bottleneck or that the drivers are not well tuned for Tri/Quad SLI.

The mere fact that these graphs don't shown minimum framerates and don't seem to stress the GPU to the fullest (using more demanding games, or ultra high res, or ultra high AA) make them incomplete.

The more appropriate comparison for Tri-Crossfire 5870 is Tri-SLI GTX 470. Tri-SLI GTX 470 has more raw horsepower than SLI GTX 480, at much lower cost and much lower power consumption than Tri-SLI GTX 480.

The point of the bench wasn't efficiency but raw power which is why the 5850 and 470 cards weren't included. I'd stay away from efficiency arguments when it comes to Fermi. Going to lose that argument most of the time due to their power requirements.

Garbage of a review.... that slower clocked i7 along with 1920x1080 makes those results absolute trash. The tri-sli and quad-fire setups need to be tested in the realm that they are designed for 2560 + res.

So.. what did you really think about it?

Geez, what a disgruntled crowd in here. If any of you can do better, then go find some benches that beat this one and quit your griping. I'd love to see them. It's not exactly easy to find a benchmark that pits all the most exotic graphics setups together.

Not everyone owns a 2560x res monitor, and when you throw in 8xAA, tesselation, etc like some of those titles had, I think 1920x can still give you a good idea of performance.

The only other thing they should've done, as has been mentioned, is to overclock the CPU a little more, like to 4GHz. I think that's holding back the Quadfire, especially.

Tri might be good for pushing the envelope in regard to performance but is it really value for money?

1 to 2 core increase seems impressive, 2-3 does not.

That's a fact. The only other benches I've seen used games that all lean towards Nvidia, so it's not really a fair comparison:

It's kind of annoying that you can't find these benchmarks and when you finally do they use odd testing techniques or games that slant to one side over the other. I mean, if you are going to test this stuff you should be using the fastest processor you can get, the highest resolutions, and as many games as possible to keep it fair.

^ Agreed. They did kind of blow this one by not OC'ng the CPU more than they did, but I give them credit for at least benching the high-end setups against each other.
