[OCClub] Crossfire vs. SLI Performance - Page 4 - Overclock.net

Personally I think almost all review sites are legit. I have no problems with this review. The problem I do have is that there are too many variables to have a definite "this card is better than this one" if they are very similar in performance. They give you a general idea but you should base part of what you think on other peoples experiences.

HardOCP is generally the best in terms of video card reviews I've found.

I have been trying to locate this for a while now and it's driving me nuts because I can't find it. Although, I believe it holds a lot of credibility because I do not believe that my GTX280 SLI setup is performing to it's best. There is some flaw in nvidia programming on i7.

I want to see a good multi GPU comparison on a high clocked yorkfield system, it would be really interesting...

I read that article on toms as well, something about the Nvidia cards not performing as well on the X58. the thing is i cant find it again either. WTH!

I actually did most of my original SLI tests using my EVGA 780i FTW motherboard and a 45nm Quad. I did notice that the GTX 260's do seem to be faster on the older nvidia chipset board compared to the X58 board I am running so that article you speak of may very well be correct.

I wonder if it was pulled at a manufacturer's request (which one would it be...)

Nvidia tends to do that along with bribery and fixed/special cards. Not a surprise.

I think i have found it, not 100% sure though. here : http://www.tomshardware.com/reviews/...80,2156-2.html

Post-testing Analysis: An identical graphics bottleneck suggests that this is not the same behavior seen before. We're seeing a definite graphics-bound condition, where the GeForce GTX 280 is hitting its limit at different places depending on processor architecture. The implication is that Nvidia's drivers are not allowing the i7 to reach its full gaming potential.

Bottom Line

The bottom line here, first and foremost, is that all of the data generated and seen in the Socket AM3 launch piece was, in fact, right on the money.

The data suggests that, using an AMD Radeon-based graphics card, you'll likely see the scaling that many other sites have presented, with Intel's Core i7 besting the Phenom II right up to 2560x1600 (refer to the first chart on this page for proof there).

At 640x480--a largely synthetic measure of processor performance, the Core i7 rules the roost under the power of a GeForce GTX 280, too. But again, the graphics load here is minimal. Anything higher--even 1280x1024, another resolution you'd expect to be CPU-bound on these cutting-edge platforms--and Nvidia's card cannot translate the Core i7's microarchitecture into the same performance advantage, giving AMD's Phenom II-series chips the advantage seen in the AM3 story and in the two pages you've just read.

I want to make it a point to thank Nvidia--specifically Nick Stam--for working with me in covering every possible base as we explored where and how the GTX 280 was being affected. As soon as we get more depth from the company's driver team, I'll post an update here. But, for the time being, I hope that the testing invested here helps clarify any questions about the validity of our benchmark results in the Phenom II / Socket AM3 launch story.

I never take anything from one review and I doubt anyone should. Pool in all the reviews and then make up your own decision. Robilar is just another review in the pool and does not mean his word is law cause he does not have sponsors.

Proof or ****.

Seriously all fanboyness aside, Each card and its competition are give or take the same. Thats what I got out of any of these reviews. To say which one is better due to 2 fps is usually bull since there are a lot of variables going into tests. For a prime and somewhat weak example, during the Crysis Benchmark, why are all the of three trials have different benchmarks? Especially the first one which is usually up to 5~10 fps lower than the rest on the same rig?

I would think the price fixing lawsuit levied against Nvidia would give some indication as to their style of business tactics...

And the other one where they hid defective chips...

And the class action lawsuit against them for not providing stable Vista drivers on its initial release (lack of SLI anyone?)

Happynix, would you like me to post links to the lawsuit details?

Bottomline is

For most people its all about bang for buck ratio and not the manufacturer/brand/make of card.
