AMD Cayman info (or rumor)

[Lanek]

nice, but here :



880MHz-980MHz = 100MHz

It don't come from their own test, for final conclusion about OC, we will need to wait a bit ... ( they just report what have been post on some forum )

Jesus !! what the hell is this

Relax boy, you're jumping to conclusions on pre launch pricing and unreleased performance.

Too bad AMD hasn't been able to up the core clocks much since 4890, it feels like they've hit a wall of some sort. This new generation from Nvidia and AMD has been nothing but disappointing in terms of perf increase. Gone are the days of 2x the performance compared to previous generation, now it's more like 1,2X.

Of course 28nm will once again bring a lot of performance since it's a full node smaller. I'm expecting great things from Nvidia and AMD a year from now.

AMD to Bring Extra-Large Vapor Chamber Cooling to HD 6900



As you can see in the image above, unlike in their previous attempts at Vapor Chamber cooling with modest sized vapor chambers like in ATI Radeon HD 4870X2, the approach with Radeon HD 6900 Series is more akin to Sapphire's pioneering 3870 Vapor-X, or recently the GeForce GTX 500 Series.

This massive Vapor Chamber cooling is the reason why AMD Radeon HD 6900 Series is achieving remarkable overclocking results, just like the GeForce GTX 580 and 570. We've seen GTX 580 working at 895MHz, GTX 570 at 880MHz as well as viewed results of Radeon HD 6970 clocked at 980MHz, and 6950 at 1010MHz. We've spoken with numerous board manufacturers and they're all telling us that this generation of graphics cards is "vintage", with overclocking headroom spanning much beyond the last generation.

Who'd knew, perhaps TSMC is finally maturing their 40nm process.

I wouldn't be surprised if ATI tapped the same manufacturer for the cooler, seeing as there is a vapour chamber and the plastic ring around the fan.

please 15th, save me, save us all.

Just ordered a 6970 for £299.98 cant wait!!!

since when is 28nm a full node ???


of course it will have the same die shrink feel as a full node .. but its not .. lets all blame tsmc and glofo for that ....

How?

Baah, then that means it'll launch at like either $380 or $400 US here.

There is a hidden link that i can't tell you about

Better then the $450 at least.

Wow, this thread really took off since I was around last time

Since you read my post wrong. The next generation is a jump from 40 nm to 28 nm which is a considerable change due to 32 nm being cancelled. And if things turn out as bad as they seem after 28nm we're stuck there for a long time.

dont be mean .. share the knowledge

i didnt read your post wrong ... because they canceled it now seems like a full node .. but it isnt according to the industry ... thats all that i wanted to post ...


but your right .. since they canceled 32nm it now looks like a full node shift ...

I said it's full node smaller, not a full node process, i.e. half node (40nm) -> full node (32nm) -> half node (28nm).

ahh ok .. now i understand where i misread your initial post ... sorry for that

scaling is trough the roof I bet.

$380 or $400 US here.

Boo! Hiss!

[Kersh]

at what time ends the nda ?

[generics_user]

If these figures are common overclocks. These would be the gains.

GTX580 772 -> 895 (15.9%)
GTX570 732 -> 880 (20%)

6970 880 -> 980 (11%)
6950 800 -> 1010 (26%)

considering the massive heatsink and power regulation i expect more from the cards
either these are clocks on stock volts or they're very disappointing considering 68xx scale above 1ghz with ease on stock coolers with a small voltage bump

lets wait till some users or real reviews post official info before judging the oc potential ... but i doubt theyd do worse then 6800 in oc headroom .. especially with the powertune feature off

I wouldn't necessarily expect the 6900s to out-clock the 6800s. They have a different and larger die.
