In that case, I take you you would love a 500W TDP card which offered 60% performance increase right?

The point of a die shrink is to reduce power consumption as well as hopefully increase performance with increased transistor counts, etc.

If all the companies cared about was "flagship to flagship performance increase", both Nvidia and AMD care highly capable of designing a card (maybe feeding off PCI-E 3.0 specs too) which offers jaw-dropping performance but also requires 3x 8-pin PCI-E and 2x old molex connectors.

Though my mind isn't blown by the 30% increase, I will still say it is a good job. Switching to GCN + die shrink can have so many problems. The fact that they are able to produce a card faster than the current flasgship and yet draw considerably less power makes me excited. Of course, Nvidia could and probably would do the same thing but I get a feeling their GTX x80 will be a beast in both performance and power consumption....

Anyway, ultimately, these are still rumors. Confirmation will only come after the cards are released and benched with other things besides 3dmark. And then we'll have months of "driver optimizations" (oh amd...) etc. etc.

Time will tell

I am OK with the 30% performance increase, but ONLY if the price isnt 550 dollars. Hell, once the 580s drop in price as they are rumored to, I'd rather pick up a few of those for much cheaper. 400, maybe 450 for 30% increase should be the price point.

ya main issue with gpu maker has always been figuring out how to make software and often they use old stuff ms is at .net 4 something etc gpu are released spanking new for w7 at lunch but ms updated that years ago gpu didnt various problem pop up.and certified version is evenolder lol.to be uptodate we would need the 7900 driver like a season ago.Often the speedup we get is ty to ms but gpu maker are credited.time your gpu release .lol.

At least it isn't as much of a claim as the nvidia ones we have seen so far. They reckon 2 times faster!

I agree, I probably won't buy this upon release of it's $550. $450? Maybe. But at that price I'll wait till Kepler, or just get a 7950.

I was going to tri fire 6950s, and then after i purchased, decided not to and wait for this, so I sold 2. If these suck, I am going to be very disappointed.

amd waited at the last possible second to release the 7900 to garanty tbemselves the title.why?sale go up with title.and in 2012 nvidia would have a product .one thing is sure amd weakest point is still their various software.nvidia was more then a year behind.intel on cpu front was a year behind amd both catched amd at software conception.does it mean nvidia will pull ahead next year .highly likly!

30% sounds about right. It should beat the 580 buy 15-20% depending upon the game.
Some people were hoping for 50-80% increase, which happens every year.

Every generation but the last one. (Which was more of a half-step than a full step anyhow.)

x1950XTX CFX < HD3870/HD2900XT (iirc anyway?)
HD3870x2 = HD4870
HD4870x2 = HD5870

They're using pre-production drivers and comparing using 3DMark, with the words that "in game performance is better". I'm willing to bet the original HD6990 in a single GPU is about right.

Same amount of ROPS, and GCN is more of a rearrangement than brand new architecture, it's still borrowing a LOT of similarities processor wise from its predecessor, as far as i've seen and read.

More stream processors is all it's really bringing to the table, as memory bandwidth wasn't a major limiting factor on Cayman. 30% seems accurate. Time will tell.

It won't touch a 1024C/512bit GTX 780.

Link to the architectural details? I wasn't aware that AMD would have any released, I thought it'd have been under NDA still.

And that GTX 780 won't be out for 6+ months after this, more than enough time for AMD to refine like crazy. That said...I doubt 1024 shaders could be easily done, even on 28nm...nVidia's shaders are a lot bigger than AMDs, after all. I wonder where WCCF got their numbers from.
That said, nVidia will have slightly higher performance...It's shaping up to be a cycle now. AMD releases new GPUs, nVidia releases a few months later with faster GPUs. AMD and nVidia release revisions on the same node later that year.

It already basically says "not true for real world performance"

Exactly. They don't even say which 3DMark, if it's 3DMark11 then that'd be not much better tessellation performance (Or the drivers aren't optimised for the new chips yet) but if its Vantage then it could just be because 3DMark tends to suck at showing real world performance these days.

Nah, 40nm was a bad node. AMD only (Mainly) bypassed the issues on it because they made the HD4770 on it first to work out the problems before they released flagship cards on it. The new architecture thing may or may not end up giving it bad yields.

Unfortunately the english language lacks a single word for "greater than or approximately equal to".

If the 7970 has approximately 60% more performance then a $450-500 price tag is fairly justified and it should also fair well against the GTX 680 (Or 780 if nVidia decide to skip numbers again). 30% more performance would not cut it in that regard.

Then type it out programming style like I would. And >=50% performance is where you'd be looking for at least, for launch drivers. (Equal to the last generation dual GPU card)

30.2 x 1.3 = only 39.3 average fps?

If that's true, then I'm waiting for nVidia.

Read the actual article, 30% for 3DMark with better performance in games.

I'm expecting at least 20 fps better on Crysis Warhead than HD 6970, and THEN OC it to make it 30fps better. This card, if the information is true, will not get my money; instead it probably will go to a 580.

I doubt any new generation in the near future will get 30fps after overclocking in Crysis...nVidia or AMD. I wouldn't be surprised if this was say, 15fps extra average and about 20 after overclocking with nVidia being 20-25. (Assuming a 1024 shader beast can actually clock high...I seriously can see it being another Fermi)

Until we have reliable benchmarks it's impossible to say. Past VLIW architectures were gaming focused, they sucked in GPGPU compared to nVidia's offerings. Now if we read any GCN arch analysis it's clear that goal of GCN to push GPGPU to catch up with nVidia, hence additional core elements and caches that doesn't accest gaming much while increasing core size making GCN dies bigger than 69x0 even on 28nm. With that said GCN can be faster, the same or even slightly slower in gaming when compared to 6 series VLIW cards. GPGPU tweaks can help with performance in gaming, but there are also can be a tradeoffs.

So unless we have reliable hard data it is just pointless to predict how good GCN cards will be.

The VLIW architecture was good for GPGPU (Theoretically superior to nVidia's architecture) but programming that wide for it sucked, as did the tools to use the GPGPU aspect of it.

24fps is only smooth if it never differs from 24fps, no dips or highs. 30fps minimum is really what's required for 3D because you can't have it at a steady fps like a movie.

As for 1080i vs 1080p...That's up to monitor manufacturers, and when I had a Xbox 360 1080i looked like crap compared to 1080p just going by movies.

Indeed, all new GPUs tend to have sucky drivers at first. nVidia got a 10-15% performance increase from the 256 series drivers for Fermi based cards iirc.

That said, 30% improvement is great for 3DMark.

I'll be disappointed if it doesn't outperform 6990.

I think you'll probably be disappointed then. We should know soon enough...

No, I doubt s/he will. It's a new generation and probably will equal the last-gen dual GPU card. 30% in 3DMark would actually be putting it up there.
