By the looks of the graphs, the crossfire scaling seems extremely good even when taking into consideration that its being run on beta drivers. Hopefully the framerating issue is almost non-exsistant and if so, the 290X will definitely be a force to be reckoned with.. especially when 4K gaming.

I want frame timing graphs. Everybody knows that FPS will be insanely high but if there is bad frame timing your FPS is just invalid.

[MJSBLUES]

So expensive..

But so worth it..

[Vitalius]

Over 80%? Awesome. Even in games that aren't Gaming Evolved titles? Extremely awesome. 

Well, looks like I may have made a good choice in aiming for Crossfire 290X's in the future for 4K. 

But yeah, agreed with lachyman. Frame timing is actually everything in regards to FPS. Otherwise it's just a number.

hey amd what bout stuttering?

what is frame timing ?

[Brainless906]

I'll just sit here and wait for charts from a website i trust.

Time to render a frame, if it's too high it is basically lag/stutter completely independent of your FPS. It was horrid before AMD updated their drivers but it's still there.

Chcek this video, Crysis 3 with HD7990, you can see stutter on 1 side that isn't as obvious on the other side. This would be even better with GTX690 because SLI is already free of these issues:

Can someone please explain to me what this quiet and uber mode is?

 

I keep seeing it everywhere but I have no idea what it means.

Some of those 4k bench's look CPU limited

Wait for proper overclocked CPU based review site bench's for 1080-1600p

the card will intentionally underclock itself to keep temps, and therefore fan speeds, low. uber is the opposite, all of the performance, noise be damned

That definitely sounds like a cool software feature. Is this a 290X only thing or does it trickle down to the  R7 270's and such?

It appears to be 290x only, maybe the 290 as well. Apparently there is a hardware switch on the card to change modes. It was mentioned in another thread that these are designed to handle up to 95c so I'd guess Uber mode will push out some insane heat. It wouldn't suprise me if the 290 and 290x were crazy power hungry too.

I think "free of such issues" is a bit ... well ... wrong. Frame timing exists on all solutions (single or multi-GPU), but is more noticeable on Multi-GPU, and even more noticeable on AMD's Crossfire. SLI is better, but the problem still exists, it's just handled better. For now. 

We still don't know about how the whole PCI-E rather than CFX bridge changes things, if it even does. And I would guess it does.

WHAT ABOUT STUTTERING

[Derangel]

WHAT ABOUT STUTTERING

 

No need to yell. Frame time is fixed on DX11 titles up to a resolution of 2560x1600. AMD is working on fixes for everything else. The article mentioned that AMD's new way of doing CFX might have fixed it in general on the 290/290x.

[EChondo]

Excellent.

 

I would still like some more official benchmarks before anything though.

[OlekKing]

Scaling seems good, consistently around 180% which is what they advertised, even more in some instances.

[James_AJ]

Pretty freaking impressive, I must say.

Hopefully this time it's smooooooooottth.

It is NOT anywhere close to be fixed, they just reduced it a bit. To tell the truth, it will never be "fixed", because we don't live in the perfect world. HW fix that NVidia deployed would be nice and much better than driver, but as @Vitalius said not even that will remove it completely.

[lhikary]

yeah no

You haven't tested the new cards, so ssshhhhhhh.....

You are right it will never be perfect, but for all intents and purposes it is "fixed" now compared to what it was before. At the point it is now most people shouldn't notice the stuttering. People sensative to it still will of course, but some of those people can even notice it even on SLI so it's easier to measure to the point where it is fine for most people.
