AMD has been using vapor chamber for ages, but once Nvidia does the same it becomes the next thing since sliced bread. :rolleyes:

These are the kinds of rumors that make it hard for people to moderate their expectations. It is just a post by some guy on a forum. Amazing if true but backed by zero evidence. Just another rumor star in a constellation spanning "it sucks" to "ridiculously fast".Quote:

Sounds kinda off though, but who knows.
30% over 580 with 6970 is not impossible,but I'll believe it when I see it :).
Maybe it is misinterpreted by him and really should be 30%-40% faster than HD5870?
Anyway I doubt that 40% faster than Cypress is enough to charge for this card £400 in the UK :)
In case you're wondering where I got that price from .... http://forums.overclockers.co.uk/sho...5&postcount=69
after thinking about it again i really expect 6970 to beat gtx 580 (those 30% might be possible in selected tests)
why? going from 5870 to 6970 we have the following improvements:
320 -> 480 shader clusters (50% improvement)
higher clockspeed
doubled front end with higher efficiency
2-3 times higher tesselation performance
doubled ROP performance
extra TMUs (5870 wasn't tmu bottlenecked)
2gb vs 1gb ram
6 (possibly 7) gbps ram vs. 4.8 gbps, possibly a reworked RAM controller with more cache = 25-50% more mem BW
everything in this list points to a performance improvement higher than 30% which puts 6970 on the same level as gtx 580 and that's a low estimate ;)
additionally an improvement under 30% (= less performance than GTX580) would put 6950 at the same performance level as 6870 which makes no sense at all...)
(please tell me if i made a mistake in this list)
It seems possible, but we don't know in what context he is talking about. If it really is that fast I hope they spend some of the extra power on perfecting IQ.
Edit: actually he does specify the context: http://forums.overclockers.co.uk/sho...&postcount=133

Don't know system specs but I would assume it would be an i7/i5 CPU. Benchmarks were..
Heaven 2.1
Crysis warhead frost flythrough and airfield flythrough
3Dmark Vantage
Dirt 2
Justcause 2 concrete jungle bench
I read it as: It makes 40% more sound at stock. :rolleyes:
30 percent faster than opponent in heaven means that they were likely comparing to gtx 580 cause we all know that 6970 is nearly 2 times faster than 5870 in heaven anyway if this bench hold any truth that means total annihilation for nvidia :ROTF:Quote:

Though it's more like 224 --> 480 if we take Barts' optimizations into account.
40 % more sound would be what, 2 dBA?Quote:

most likely.. 30-40% faster than 580, I don't think so :rolleyes:

thanks, corrected ;)Quote:

We get 80% faster than Radeon HD 5870. Not entirely impossible seeing that this leap is pretty similar to Radeon HD 3870 -> 4870.
This is what I call over-hyping!Quote:

Please I know this is an enthusiast forum, but being more realistic wouldnt hurt... :shakes:
woooow comparing the leap from 3870 to 4870 with the 5870 to 5970 is wishful thinkingQuote:

6970 is going to beat 580 by a small margin (5-10%) everything else is overhyping
@Shadov: DualGPU card is going to be lower clocked and i expect it to be only 50% faster than a single 6970
I can play crude math game too : if we take 6870 as a baseline,we have 1920 vs 1120 SPs.If we assume that the new 4way arrangement brings 90% of 5way performance in games and if we figure in the clock difference(that is in 6870 favor,900Mhz vs likely 800-850Mhz for 6970),plus a better mem BW(10% perf. increase impact) for 6970 we get : 1920/1120*0.9*850/900*1.1=1.6x faster than 6870. According to the image above, 70x1.6=112pts or 12% above 580. That's reasonable,12% I can buy. But 30-40% above 580 is highly unlikely IMO.

now if they mean faster than 480 then I could believe that.

mine sounds much more realistic you must admit it :D seriously one must be fanatic to believe 30-40 percent differenceQuote:

it's a bit too huge in my mind, and i'm pro AMD.
