[PCPer] Frame Rating Comparison - HD 7950 CrossFire vs GTX 660 Ti SLI (full review) - Page 3  

post #21 of 542
Maybe I am just blind, but to me it looks like the SLI setup has more noticable stutter?

Maybe in BF3 but not in the others, it has it's own set of quirks though.

Sorry my english.

Youtube videos are 30Hz so unless you slow down by 50% you are losing frames.

Hmmm, I'm mid-thirties but thanks biggrin.gif

Some people can be neutral, and software to measure this output accurately now also helps

The only thing that bothers me about the "observed" framerates that this testing gives us is that if we're not really seeing ANY more frames with CF (see: http://www.pcper.com/image/view/21524?return=node%2F56812), wouldn't users have complained that there is no difference?
I mean, I can easily tell when my FPS drops to 50 FPS or less, so wouldn't it be super obvious that you are getting 40 FPS instead of 80? I would think there'd be far more unsatisfied CF users if this was the case. Or can this be blamed on some bias? That the brain just decides that since that little number in the corner of the screen doubled, the image is more fluid?

690s in sli. if any of my cards did that they are off to rma. seriously cause that is disgusting.

edit: i only play bf3, c3, c2, and ps2 with crossfire. ps2 was not as smooth as single card setup.



First off, don't get hung up on performance of a beta.

Secondly, that video was uploaded before the Keplar series was even releases.

Lastly....who would play Diablo 3 in SLI'ed 690s.

Either you're accidentally mistaken, or trying to spread false info to the uniformed. Surprising behavior from somebody with 4,000+ posts

this was suppose to some out today:

Summary Thus Far

Because of the complexity and sheer amount of data we have gathered using our Frame Rating performance methodology, we are breaking it up into several articles that each feature different GPU comparisons. Here is the schedule:

3/27: Frame Rating Dissected: Full Details on Capture-based Graphics Performance Testing
3/27: Radeon HD 7970 GHz Edition vs GeForce GTX 680 (Single and Dual GPU)
3/29: AMD Radeon HD 7990 vs GeForce GTX 690 vs GeForce GTX Titan
3/31: Radeon HD 7950 vs GeForce GTX 660 Ti (Single and Dual GPU)
4/2: Radeon HD 7870 GHz Edition vs GeForce GTX 660 (Single and Dual GPU)
4/4: Radeon HD 7850 vs Radeon HD 7790 vs GeForce GTX 650 Ti vs GeForce GTX 650 Ti BOOST

but maybe because of the Holiday / weekend it hasn't appeared. redface.gif
