i get headache when i watch too many 3d stuff with the glasses on ... so i would agree with cegras about the 3d claims ...
are you talking about shutter glasses or polarization glasses in general? the former suffers from flickering so that's probably the reason for your headache.
lol... how would you get cross-eyed by using polarization or shutter glasses? you're not even crossing your eyes with these.

First samples of Radeon HD 6900 getting close
AMD is struggling to improve availability, but now it seems things are improving as soures to NordicHardware reveal that the first samples are expected in two weeks. After delays that was partly because a new power supply, but also other reasons.
There have been rumors of AMD's delay of Radeon HD 6900 series would be poor availability of power regulators from Texas Instruments. This was confirmed by our sources, but it wasn't the only reason for the delay. The power supply of the Radeon HD 6900 series is much like the one used by the Radeon HD 6800 cards with Barts GPU, which has also affected the availability of the series.
The information from AMD is otherwise relatively scarce, but it seems pretty clear that the delay is not because AMD has tried to revise specifications in order to meet with GeForce GTX 580. According to PowerColor Radeon HD 6970 will offer 30-50% better performance than current generation graphics cards. One wonders if this will be enough to match GeForce GTX 580 and then AMD also has Radeon HD 6990 sporting dual GPUs around the corner.
In the near future we will have more information on AMD's new graphics card, whether we have the possibility to share before week 50 when Radeon HD 6900 is said to launch remains to be seen.
AMD surely teaches us how to be patient... ^^
man i just want to see official numbers ! see if it's worth the wait or if i go for a 480 / 580 on sale ^^
lets not confuse review samples with engineering samples. Availability should be reasonable as it is the reason behind the three weeks delay, maybe quantity is in the single thousands first but it should be available. A paper launch could have been done on Nov 22 but it wasnt.
i feel that amd failed badly this time they pretty much missed christmas sales which was crucial for them
people who buy 500$ cards dont wait till the holidays to do it.

The lab at Stanford came back to Sega with dire warnings about the hazards of prolonged use of this technology. SRI warned Sega:
“You Cannot Give This To Kids!”
Pesce says that Sega took the test results and buried them. Fearing lawsuits and consumer backlash over health risks, the VR Headset never made it to market and neither did the truth about the dangers of prolonged exposure to 3D virtual environments - until now.
VR helmets were small tv's 3 cm from each eye in a completely dark environnement, after 15 minutes it was headache for sure.
i cannot see it even close to 3D glasses were the effect is just luring the brain, maybe an issue with the frequency of active glasses.
how many people do you think are out there who can tell their mommy to go out to best buy and pick up a 580, then WAIT until xmas morning to open it up.
people who can afford a 500$ gpu, are the kind who buy something when the want, not when santa says so.
the loss of holiday sales for a 300$+ gpu is minimal compared to the total sales across the next 8-12 months before 28nm comes out. now if things were revered and the 6800s were late, then this holiday the 460s would take most of the pie.
I agree 6800 and closing the gap on 460 was way higher priority before christmas than getting Cayman out.
Dont forget 5970 still holds its own till Cayman is there.
For Nvidia priority was getting out a new product in time and it was a very good response and should boost their dx11 share up somewhat but not as significant as the 460 did.
cmon, how many 5970s are there in stock worldwide? 50? 100 maybe?
iirc focusing our eyes is harmful if we do it a lot, and depending on how well the 3d illusion works, our eyes might actually notice its an illusion and refocus over and over, plus focusing on different depths that dont actually exist...
so its not just flickering...
whats there to wonder? a 580 is around 30% faster than a 5870...Quote:

depends what settings though, with 4x AA and 16AF and high resolution. It grows wider.

http://www.hardwarecanucks.com/forum...review-24.html
With decent AA and 16AF, a gtx 580 can be faster than a 5970 which is atleast 30-50% faster than a 5870.
If the original rumors are true and that 30% is compared to the 6870, then you add another 7% to that figure.
Regarding eye strain:
Permanent eye damage can occur from your eye constantly refocusing / under strain.
In fact, that's how near and far sightedness starts often: eye muscle strain / weakness ends up affect eyesight. Those of us who have had eye surgery also know from the doctors not to do things that strain our eyes for the first year, since it can hamper recovery.
That's why I tend to stay away from 3D stuff anyways... most of it my eyes can pick up the fact it's not, so I noticeably feel eye strain after watching something for a few hours.
Regarding Christmas availability:
Honestly, a $350++ video card is such a niche product that buyers aren't waiting for Christmas. Both sides have launched cards at random times (the 8800GT and Cypress were all launched during non-holidays and sold like hotcakes) and haven't been hampered. Christmas is when your lower end cards are most likely to be moved - enthusiast grade cards are called enthusiast because that's who the buyers are. They ain't waiting for Santa
Lots of things cause eyestrain, from watching tv or movies in the dark to sitting to close to your television. Heck some CRT monitors too. If this was as dangerous as a couple people on hear are making out to be, there would be crazy amounts of lawsuits and more evidence against it.
The 3d is bad for you really didn't appear on this board until AMD version was shown to be buggy and full of errors. Nvidia version is too don't get me wrong, but AMD's is completely broken.
3d is bad has always been around, it's just not a big issue since it was pretty niche
And it is bad for you, lawsuits etc. don't matter - it's your fault for using it, after all. And doctors do warn people about eyestrain, but as we all know, most people don't care until it's too late

Yeah, I stabbed out one of my eyes so I wouldn't have to endure the strain of seeing the world from two separate angles all the time. Binocular vision is overrated, yarrr.
The issue with either shutter or polarised glasses is not so much that you are seeing two slightly different images (this is how our eyes work after all), but rather that it tricks our eyes into trying to focus on something where it is not. Hence, by looking at '3D' images all day, we are possibly training our brains/eyes to focus on a plane located in a different position to where we perceive the object we are looking at. This is why so many people get headaches or just more worn out while watching 3D movies (rather than regular 2D).
For example, you load up your favourite game (now in three-dee!!!) and see a zombie rushing at you. It was at first 5 meters from you, then 3 and then OMG! it is right there licking the sweat from behind your ears. It seemed so real that you thought you had caught the infection. Your head even began to hurt. Ow. The reason was the zombie was never 5 meters away, it was half a meter at all times. Your brain 'saw' it at 5 meters, told your eyes to focus at five meters and discovered things got blurrier. So your eyes refocused at half a meter. But then you realise that the zombie is at 3 meters and so you try to focus at 3 meters...etc, etc, etc.
If people don't get some form of eye damage from sitting in front of a 3D settup for long periods of time I will be surprised. Not interested in it until health concerns and comfort are addressed.
I didn't know there were so many part time ophthalmologists here on XS ;)Quote:

Looks like we have another Charlie here. Strange he is always so much critical of the other Charlie.
I believe except you people were talking about 3d in general. It's OK but what is strange, you're the one always talking so much about fanboyism.
Don't turn this into a trolling fest with personal attacks. Charlie would be spouting hate about AMD/Nvidia and getting happiness out of this delay. I am just making a pretty normal comment about first samples being sent now. Compare this to charlie who says nvidia has no cards, they are lying to shareholders, all they can do is spin spin spin, etc. I hold Charlie a lot more accountable and we should too because he is a journalist and getting paid via advertisements to run his website. If your going to say something negative about a company the way he does it, you better be darn right.
I am not getting joy out of this delay and I would rather the card came sooner than later.
I think the reason 3d was mentioned in the first place was to bring down a strength of Nvidia cards, over AMD cards. I simply asked for real evidence which is fair when i provided evidence in my original post.
Seriously leave the personal attacks out.
please stop the "3D influence on eye sickness" fight here, start another thread somewhere else (maybe doctor online ^^ )
According to latest news from Napoleon at Chiphell 6970 new release date is December 7.

HD6970 to compete with GTX 570, not 580
http://www.donanimhaber.com/tm.asp?m=44558753
http://translate.google.com/translat...3Fm%3D44558753
Older rumors had "6950 trading blows with 580"... newer rumors have "6970 trading blows with 570" :D
Well stop with the rumors then, i dont want the 6970 trading blows with 480....
Obviously they know nothing and just repeating the rumors of 1536 SPs and 30-50% performance increase over 6800 series according to what the PowerColor rep said they were expecting. Still even that would be about as fast as a GTX 580, and certainly faster than GTX 480/570.
LOL, if HD 6970 is trading blows with GTX 570, then HD 6950 would trading blows with HD 6870. :ROTF:
A little bird told me that Antilles will need OC to perform like a 5970.
this little bird?
http://safadezaoculta.com/wp-content...trollface1.jpg
:rolleyes: That is doubt given the track record of ATI, 4870>3870x2 5870>4870x2 so the 6970 should be >5970. That is what is most likely. Antilles aka the 6990 should be a lot faster. Considering AMD has been withholding the final bios for Cayman your little birdie has not seen final results yet.
You're replying to article which doesn't say anything about paperlaunch and you call me troll? I'm sure if the author of the article wanted to leave such message he would say so, after all it would make very good headline.
I compared you to Charlie since he made the same prediction about the GTX 580, simple as that. I'm sure most people ready to purchase high end Video Card from AMD or NVIDIA hope you're also wrong as Charlie was.
About the 3D. The people responding to your opinion about 3D clearly talked about the 3D in generel it was ONLY you who changed it to Nvidia vs AMD argument, how more clear I can be about that, is that a personal attack?
Look at the other elements. The card is late, it has missed a direct confrontation with its competitor and might not make the Christmas season. In addition, rumors of part shortages in making the cards do not inspire confidence that there are going to be alot of these cards. Considering there is already a shortage of 6870,6850(a card that should be easy to make because of its small size), thus the cards being scalped 20 dollars. I have my doubts how much parts AMD can deliver, considering how much bigger cayman is, the short development time, has 2gb of ddr5 @ 1.5ghz(which nothing else on the market has) and this power components from TI. And their has been a couple people like the poster from India who says, the cards are not at India AMD headquarters. A paper launch could happen.
Paperlaunch does not have to be a troll-word, if their is a reasonable case for it. And even the word itself is not really that trolling. Something like AMD sucks or Nvidia is crap is trolling.
Everyone was saying NV was going to paper launch the gtx 580. Shall we call everyone Charlie then?
That's an absurd to call a person charlie just because they say paper launch.
Charlie has a particular brand of writing that makes him who he is. I share none of that vehemently hate to where I see joy in a company failing. This is what separates normal writers from Charlie, his obsessed hatred towards Nvidia.
A personal attack is more likely to get a negative response and your just asking for a flame war.
Cegras original response was to someone talking about NV 3dvision.
XT 890mhz $449
Pro ??? $349
Many various and contradicting rumors swirling around out there, can't get any better info on NDA/launch.
Craziest one I have heard is that the Pro model will be on shelves by the 7th but NDA doesn't expire until the next week.
Lots of talk about a double launch of 3d products, glasses and monitors, as well as FutureMark 3dMark11 benchmark will coincide with Cayman release.
If the pro shows up for $349 and performs like it should, it may very well end up in my system IF I can get my hands on one in time for my buddies girlfriend's kids computer, and it manages to over-throw the GTX 570(winner of that battle gets a 1 way ticket into my PCI-E slot). They're paying me $150 to build the system, and are offering me a more-than-fair price for my GTX 460, which between the 2 my upgrade will be free. :up:
Although, maybe I'm wrong here, but that's quite the price gap between that and the 6870... Shouldn't there be something to fill that? I smell a 6930 coming soon afterwards.
As much as people paint me to be "biased", that's really not the case. I side with whoever gives me the best performance/IQ for the money I'm spending that particular day. I just see the flaws in a lot of the arguments that takes place, and there's more red paint than green paint here if ya know what I mean.
yep youre right from 250$ 6870 to 350$ 6950 is a huge gap indeed and the better the caymans perform the larger this gap may get im afraid. im actually hoping nvidia puts out a dual gpu as well so there is some competition on that segment too otherwise antilles will be the fastest but most inaccessible card ever created.
The way supply situation going on the red camp, i'm affraid these cards won't be cheap afterall, street price will be inflated in no time after launch, no matter how sensible AMD initial launch price ever was. :rolleyes:
wow 0 infro in 2 weeks lol this is new record i must congratulate amd for pulling such strict nda up
how can we know there is something wrong when even the initial nda for the 6900 series isnt even over ....
still 2 days to go left
None off the GTX 580 Newegg has listed are at $499.- MSRP, so everything is going to be just relative.
About the bart supply, Newegg has out of 14 HD 6850 listed 11 in stock,
there are 11 HD 6870 listed at Newegg and 6 are in stock, that's not exactly bad supply for a card which is right now on Newegg HOT seller list, AMD also has to supply many off the cards for the ready boxes.
Just to compare, there are 11 GTX 580 listed at Newegg and only 3 are in stock, considering GTX 580 is not exactly hot seller mainly because less people buy the top end cards and some off them are most likely waiting for the AMD HD 6900 cards just to compare the performance and value.
Anyway my conclusion is that bart as of today has much better supply than the GTX 580.
As for the GTX 6900 we can only hope there is not going to be any paper-launch as somebody in this thread predicted.
I guess giving you the figures supported by links didn't help at all. With 20 barts card available at Newegg one can hardly call it bad supply, considering not always Newegg has all the cards listed in stock at the same time or comparing to the GTX 580 cards availability.
I believe the 20-30% over MSRP might be little exageration on your part, even more so if the competing cards are also going to be available.
The only way such mark up would hapen if the 6900 cards are priced lower than the GTX 500 cards and perform much better which i doubt will hapen and if it does it would be still good value when compared.
I believe the 5850 is just missprint since the card is EOL but there still plenty on sale at Newegg.
so if that would be the case then pls explain me what they will put into antilles?
cf 6870 beats 9/10 always a 5870cf setup....
so if they put a dual bart XT on the antilels design, which is no issue power consumption wise they already have a faster card then 5970 :rolleyes:
off course it could be that they use a more reduced cayman for antilles but i doubt that if they can use smaller die...
if you find 1 type of 580 for each store in Europe you have lots of luck, that hard to find and even first week when people reporting newegg sales of 580 there were never in stock not even for pre order.
Yes, that's a correct statement if you're looking at the same point in space. 3D splits that into two for you.
http://www.audioholics.com/news/edit...o-your-health/
Furthermore, another glaring problem is simply how fake 3D looks; everything is in focus, there is no focal plane. There is depth being projected to you, but none into the screen.
To me it all depends on the game really but I really can't see 3D as a huge leap from general gaming. It would possibly be nice to have in games like World of Warcraft and maybe racing, but I can't see how 3D would give you any advantage in FPS games. Quite the opposite I'm sure most of the best shooters out there would never use this kind of technology.
Eye candy only goes so far into the game experience and 3D immersion is far from the most important aspect of eye candy, textures, lighting and shadows will still rule for a long time to come.
Still there is no indication that the problem is because of the separation of images. If anything I'd suggest it might be because of the lack of eye accommodation.
Basically your eye automatically refocuses on an object that you are viewing, casting everything else out of focus. In current 3d tech your eye is focusing on a plane (the screen) and everything viewed on that plane is in focus unless they specifically defocus it. Eyeball tracking and depth of field could solve these problems, but render it impossible for multiple people to view simultaneously.
The whole point is that a planar image is split into two slightly offset images that give you 3D perspective, right?
So if you start watching 3D, your left and right eyes are not looking at the same object; they're looking at an object that has been split slightly left and right. It's like slightly crossing your eyes (I say this because diverging your eyes is impossible to do manually) for hours on end.
It's not the same as looking at one object, which is what some animated gifs do: rapidly blink back and forth between two perspectives of one object, but don't change the center point.
But each offset image is just capturing a closer plane from each eye's cone of vision aiming at that object. I don't buy that as a cause. I'd say if anything it's more likely eye accommodation. Basically your brain thinks it should have to refocus when looking at a nearer or farther object, but it doesn't since they are all in focus on the same plane (the screen).
Zzz. Last few pages filled with 3D stuff :/
Anyway, to add fuel to the, uhh, nothing, a little birdie told me to expect clocks between Juniper and 900. Hmm
Exactly, there are no focal planes in stereoscopic 3d. It's all on the same plane but the difference in angle between objects makes your brain think that they are at different focal depths. So when you look objects in a scene your brain will want to do what it normally does automatically and try to refocus on that object. But there is no refocusing to be done.
Anyway, the mechanism isn't important. Forget I mentioned it.
Here's to good supply! Helps with cost!
I know Cypress wasn't memory bandwidth starved, but almost no improvement?
it seem 2GB of 6-7ghz have a very high cost, and that mean 2GB low frequency is more faster on cayman that 6-7ghz 1GB.
Cayman is highend with very high res and eyefinity mean 3x24" or 6x24" !!!
So cayman seem to be the true first Good eyefinity done !!!
1920 shaders is good, and the most interresting that we does'nt know before this slide the 2 poly /cycle. This is an awesome improvement !!!
96 TMUs :confused:
more tmu's always sounds nice :D
Finally some good slide leaks. Anyone remember this ? http://www.fudzilla.com/graphics/ite...o-hd6970-specs:ROTF:
1920SPUs + VLIW4 potential beast on paper just hope ROPs doesn't bottleneck it.
It was already mentioned before (2x times previous gen geometric processing power)
http://img221.imageshack.us/img221/4204/94189504.jpg
50% more SIMD engines + 2 tri/clock looks nice, but memory bandwidth + 32 ROPs seem to be too much conservative.
plus drastic improvement in tesselation not mentioned in this slide but which rumors claim will be 3x faster. If this is indeed a big chip then maybe the 32 ROP and 256 bit memory help keep the transistor count down. I sure Southern Islands will boost more ROPs but I think AMD is addressing Cypress' weaknesses mainly with this chip and ROP and mem bw were not really big weaknesses of cypress.
from memory bandwith i guess cayman will have 5-5.2 ghz gddr5 not 6 ghz as some suggested
