AMD Cayman info (or rumor)

[HelixPC]

If thats true, the GTX 580 is in big trouble! And i will pick one up day 1

Dont know if this is trustworthy,

that site is very well known as far as i remember

[SpuTnicK]

I added link to the source. check that post again.

[kuroikenshi]

If that's true.... well GTX580 will only have a couple of weeks as the tessellation king (and single gpu king)... fail king

lol

Really funny, for sure ...

Really hoping it will at least perform equal to the GTX580 (a loss of 5, maybe 10% aint that bad, beating it would be great). Not because I wouldn't want a nVidia card, but because I hate dual card setups (using Eyefinity at the moment), 2 GTX580s cost a 1000 euros & will make a pc consume about 650 Watts during gaming on the graphics side alone (2x 250 Watt & 3x 50 Watt for the monitors).

I'd rather have 5 to 10% less performance (and a cheaper card) if I can avoid the required SLI for nVidia's solution and only use about 400 Watts at the graphic section.

This information had nothing to do with dual gpu cards, only single gpu cards, 6970 is a single gpu card .....

[Vipeax]

And that is why I am hoping that it performs at max 10% less than a GTX580 and hopefully better, to avoid having to Crossfire (to get enough FPS)/SLI (cause 1 GTX580 can't run 3 monitors)?...

What I find funny is how everyone is amazed at 20% performance improvement over GTX480. How the hell can that be impressive?!

I still remember the bashing AMD got when HD5000 series was not DOUBLE performance over HD4000 series.

Srsly WTF?

dude you missing the idea here. the HD5870 was a die shrink and spec wise it almost doubled the HD4870. 1600shadders compared to 800shadders, most people are going to think that means double the performance, it also had double the rops and a higher clock speed. so on paper it was twice as fast however when it came down to it the HD5870 was rarely close to being twice as fast because of the poor shadder organization and layout. it also used more power, was larger and gave off the same amount of heat compared to the 4870. and took more than a year to come out. however the HD5870 was (and still is) a great card that caused ATI to take back the fastest single GPU crown for a good while. i can't really remember much complaining about it... even by nvidia fanboys considering how the performance was good and how it brought DX11 and eyefinity to the table.

why are people impressed by the GTX 580? because it's out like 7 months after the GTX 480, it uses less power, puts out less heat, is smaller, is about the same price (in Canada), and is still 20% faster without a die shrink... and it OC's pretty good as well.

on to Cayman, these leaked specs seem to confirm the rumors 1920shadders, 4D layout, 2GB of ram blah blah blah. come on AMD leak something good like a bench or something this card will be powerful but it just does not add up to have it beating the 5970. yes the shadders are better used and there is less wasted power, but a 1280SP deficit is not easy to overcome. I think if anything 6970 will end up neck and neck with the GTX 580, leading to fanboy violence from both camps, a brutal price war and smiles on all the kids faces at Christmas.

[kuroikenshi]

massive problem here, I am decades past being a kid, so how am I going to justify an upgrade by Christmas???

So that's equivalent to some 2400 Cypress shaders for Cayman XT. With all the other improvements I'd say something in range of 40% faster than HD5870 is doable.

No, nVidia fans were all over how GF100 will beat 5870 to obvilion.

Thats not impressive, 10% that is clocks, that leaves ~5-15% depending on situation for full CUDA core count and improvements. I really dont see anything impressive. And 7 months.. Do you really think that in time when nVidia was trying its ass to fix GF100 they did not come with lot of ideas, but those ideas could have not been implemented in time. So they did what they could, bubblegum to get GF100 released and then work on other improvements that take acceptable time to do to try to catch AMDs lead.

Well, performance leaves to be seen. I have no trouble adding up to 5970 performance, as you yourself said, Evergreen is very inefficient design. What do you think that Cayman is all about? its finding the right mix to get it efficient at high shader counts. I bet Barts is what it is becouse that is Evergreen designs "sweet spot".

[Lanek]

What is sure, thoses spec match the last rumored spec... maybe a bit too much, i don't read chinese, are you sure he just not compil the last rumors ?

If you're married, as either the husband or wife, I suggest you go to your knees and make a very persuasive oral case.

In this case it beats GTX580.

I guess it depends on how receptive she is to that particular 'argument', just remember to stay firm. We're behind you on this one.

Partners not getting their AMD Radeon HD 6970 boards in time has led many to speculate AMD is indeed facing yield issues with its upcoming flagship GPU. However, an insider has shared a contradicting piece of news: the card's delay is not due to yield issues - production is perfectly fine, but rather a shortage of a particular component from Texas Instruments (TI) is the root cause of the hold-up.This TI component is an integrated driver-MOSFET (DrMOS) that was first used on AMD's Radeon HD 6800 Series. This DrMOS is so new to the point there is no information on it on the Web, not even from the manufacturer itself.

Supply of this DrMOS is limited, and since the Radeon HD 6800 Series and upcoming HD 6900 Series share the same VRM design, any (tight) supply from TI is shared between all the cards. This leads to a delay in HD 6970 card manufacturing, with partners receiving their final boards late as well.

It is interesting to note that AMD has also withheld the final BIOS from partners. It is an open question as to whether NVIDIA's just-launched GeForce GTX 580 flagship GPU and its performance figures has anything to do with this. That aside, the initial 22nd November date may be set to change; AIBs will only know the final launch date from AMD at the end of this week.

If these numbers are genuine it should be way above that. HD6870 is about 2 GFLOPS. So we're looking at around 50-60% over HD5870... and possibly a match for the 5970.

The chiphell admin basically created a very gutsy thread titled
"No more 6970 performance predictions allowed!", and left this nugget of insight:


"Yeah yeah it's faster than the 580 alright, no speculation on how much faster!"

If I were one of those pathetic fanboys pretending to care about consumers I'd be oooooh disappointed now.

Too bad we now have to wait two whole weeks to see the hard numbers .

[kuroikenshi]

LMAO, what a way to pave the road ahead, hopefully silly fanboisms will dilute from here on.

[Chrono Detector]

Yeah it would be wise if the 6970 had 1920 shaders instead of 1536 like previous rumours stated, why would the 6970 have less shaders than the 5870? Didn't make too much sense.

that's all I care about right about now

More equivalent to 2400 Bart's shaders IMO.

We're talking about Hemlock class performance here.
