Good god,  4x 6pin power plugs!?!?  What a power hog this is gonna be.  ::)

????

Most normal dual GPU cards feature a 2x8 pin power connector arrangement for input of 150 W each (official, they handle more)

This card has 4x6 pin power connector for input of 75W each (official, they handle more). Notice the math there?

The difference is in how it allows handling of incoming power, the power circuitry is unique to this card. These four 6-pin connectors give the card a multiphase power regulation, which is divided into three groups.

So to say it's a power hog based on it's connector style is wrong.

It will undoubtedly be more power hungry than a 690 from the green team, but it will also be faster. This has nothing to do with how many power plugs featured.

Wondering, would mining on it profitable at release date?

I have been waiting for these things since march...  i have SeaSonics and mobo ready...  but to waste 4 of my precious gpu power connectors on one card... NO THANKS.     i hate molex connectors.


bummer.......   >:(

Quite so. I can't figure it out, it seems to me that the most logical thing would be 2x 8-pin: 150w each, = 300 watts total, whereas 3x 6-pin: 75w each, = 225 watts total. ???

Do the PCIe bridge chip and the memory really need as much power as both the GPUs combined? ???

EDIT: Derp, 4x 6-pins, not 3. Still it works out to the same wattage as 2x 8-pins.

The PCIe bridge chip should use barely any power. The RAM should not use anywhere near the GPU's lol.... that would be madness

Exactly. And yet, some are postulating that the necessity of 4 connectors is to provide better power or something, and that some of them would be dedicated to the RAM and others to the GPUs. Madness.

Maybe has an 8-phase PSU.

It's a three group multiphase power regulation...

Not for MORE power, for better power, these chips will clock like crazy. The voltage input on these chips will be very stable.

still, dont think it will be worth 4 pci cables...  im not even sure win7 will load 4 of these monsters

16pci plugs..what a clusterfuk

+1

"Damn you AMD you designed it to be MORE stable for overclocking but now I have to use these 8 pin to 2x6 pin adapters, YOU BASTARDS!"

Wouldn't it be better if they stopped worrying so much about overclockability and all the caveats that entails and just made a fast card out of the box?

Maybe even make it run off of two 8pin cables, that would be so cool. ::) ::)

yeah, it'll finally beat the 5970 in gaming performance

Doesn't powercolor's card have 3x8-pin PCI-e?

You could run 3 of those off an enermax platimax without any additional connectors... would be good for something like 3.7Ghash.

It is a fast card out of the box...

Here's the "thing". In order to comply to the PCI-e official specifications, the card has to remain within a 300W (or less) power envelope out of the box. So when you take it out of the box and plug it in it's fast, but only 300W (or less) worth of fast. That means if Joseph Ding Dong with his shiny whitebox home built PC and FANCY Diablotek 650 W Firestarter (err I mean power supply) plugs in this card, it might actually work without blowing up in flames. Might (It's a diablotek after all) Conforming to the PCI-e spec means these things can be certified for use in OEM machines like Dell and HP etc...

Now Jo Over Clocker with his 80 plus Gold rated 1500W monster plugs in two of these beasts and decides to feed them every watt they can handle to the tune of 450+ watts a piece and squeeze every single pixel out of them... well the cards are wired up for that too... beyond the PCi-e spec.

A lot of big PSU's have multiple rails and it's nice to be able balance something like this across them.

tl dr: the card is made for gamers and gamers rigs we are a secondary market only.

I guess my sarcastic point was that for the costs associated and the grief in engineering they should have just made a more 'normal' dual gpu card and be damned about all the extra bells and whistles for super overclockers as they hold even less market share than miners do.

That's an interesting point. These particular cards are the top of the line extreme items and will carry hefty price tags. This kind of mark up demands superior engineering.

IF board partners (like Powercolor or Sapphire etc) wanted to make 7870x2 , 7950x2 or even simpler 7970x2 etc... then they COULD. It's entirely within their scope and they'd do it if there was a market that they could latch onto. I'd say by the absence of such products, there is little market that they feel they could capture outside of the existing product lines.

The assertion that more people mine than overclock doesn't ring true with me in any case. The big forums like H and Xtremesystems and so on definitely add up to more enthusiasts than BTC miners.

So a nice dual card that undervolts and is easy to manage could be aimed squarely at the miners, but I think dedicated mining hardware from places like BFL is showing that this particular ship has sailed.

Don't get me wrong, I am not asserting that there are more miners than 'general' overclockers, but I am saying that there are probably more miners than 'super' overclockers that know what multiphase power is going to get them and how best to turn that into a competitive advantage for the benchmarks. (as I don't think they actually play games like that)

Your general enthusiast will probably OC their card a bit for better framerates and some e-peen but they will probably not be able to fully utilize these new multiphase power setups to their upmost as 1) they don't care and 2) they are not going to mod their card aside from maybe a water block.

I fall into this 'general' overclocker family as I will OC my card(s) for better framerates but I will probably not utilize "three group multiphase power regulation" to its fullest ever. I am sure I will not want to deal with the extra heat and noise that OCing my card to the roof will avail me. Most games its diminishing returns anyway.

The heat is a boon in the winter, considering most "portable space heaters" run around 1500 watts, a PC can easily replace one in a cold room.

That made me laugh. Playing BF3 (or whatever) to stay warm.

I don't doubt these cards will go out in the 900+ territory, that's a lot of home heating fuel.

So what's the latest on the actual release date?  I'd love to pick one of these up for BLOPS2.

And has there been an MSRP released yet?

Anyone have anymore info?

But the thing is, all those connectors are DC. The multi-phase arrangement is part of the PWM system, which doesn't care how many DC connectors there are as long as it gets enough volts and amps. You could have one big ass pair of wires per card, and still have stable power, since the PWM system does all the magic.

Exactly.

OMG FOUR pci power connects?

I love it!  This will be the most epicest video card since the Voodoo5 6000.

https://i.imgur.com/YulCm.jpg

Maybe ATi should include an external power supply too?   ;D

This is epic.

Most mining rigs use ext. Powersupply anyways :)

I remember my V5 5500. It was a beautiful thing, too bad 3dfx stopped innovating and rested on their laurels so much.

What ever happened to 3dfx anyhow?  Didn't they get absorbed by a larger company somewhere along the way?

I believe Nvidia bought them out around 2000-01.


EDIT: I remember my Voodoo 5500 AGP well, was the only worthwhile card for N64 emulation.

Could we please stay on topic?

Actually it does care and care a lot because not every PSU is a monster single rail of 12v. Love em or hate them multi rail PSU's often can't deliver the amps needed to a single 8pin connector. Instead of forcing people to upgrade their PSU's when they make dumb choices on their six rail 1200W  monster (or two rail 700W shitbox) , they're accommodating them with this design.

So obvious.

What do you think about this (http://www.fudzilla.com/home/item/28362-powercolors-dual-hd-7970-devil-13-coming-soon)?

Ya that showed up a few months ago. Looks sweet, but it's not an official 7990 (it's more of a 7970X2). Still, I expect it to be a killer card.

Ps Are they using GHz edition (tahiti2) chips undervolted and downclocked to 925MHz? That would make the most sense for a custom card with these clocks.

You can get them for $370 each, but that's not ATI's official MSRP. That's actually $425, or $499 for the GHz versions.

Ow yha these guy's are not bfl, they can't afford to make customers way for month or more ;)

Soo...where are the review, and where can I buy?!

There's a strong part of me that wants to take 200BTC and WC 2 of these in CF. How long would 2.5GH/s take to make back 200BTC... /doesntcare

Me too  ;D

Well @  ฿31.32 per month,@ $10 each=$313.20 per Month @ current diff  8)

 About 3 months to pay off each one.I'm guessing retail price @ $1000  :o

Out of my league,unless BTC hits $20  ::)

Your not counting the power cost and new PSU that will be added to the cost. What i want to know is how much is it gonna cost, and more importantly when does it go on sale?

My PSU can handle 2 of these. The cost for me is getting them, which is still unknown.

Why is stuff always more expensive in Europe, I mean that site showing 900EUR equates to be about $1500 USD

"Hardware Canucks has leared that the price will be between $899 and $999 USD"

The only reason I am thinking they would be any better is that I could effectiively run 4x 7970 in a single rig (most of my boards are 3xPCIe16 double spaced)

Isn't 900 Euro closer to like 1125USD?

That PowerColor Devil 13 HD 7990 is not a standard 7990.

It's a higher end hybrid.

I'm sure the ref or standard 7990 will be less than that one  ;)

3 - 8 pin pcie connectors.  Wow.  It would be better for mining to make a card that can get down to two 8 pin connectors and may run at a lower maximum clock rate with far less room for overclocking.  Of course this is not going to happen now that ASICS and FPGA's are around.

They did not build this card with miners in mind specifically. Yes it will mine great, but they built it the way it is for a reason.

I want four of these in quad SLI.  Because Crysis.

*orders dilithium crystals for antimatter PSU*

True.  It is a top gaming card and most probably would be faster then a reference card by ATI if one does come soon.

1) These (and other previous gual-GPU cards) only have 1 CF connector. Means only 2 cards (4 GPUs) in a system.

2) How were you planning to fit 4 seperate triple-slot cards into any case? You'd need a 11 PCIe motherboard, which they don't make.

Uh,not quadcrossfire,but OCTOcrossfire (2 cores per card=8),if you meant 4 cards   :o

Extendo PCIE cables will get them hooked up,but the OS using them all could be a problem  :(

You don't need to make back all the money you pay for the card, just think of it as getting an awesome gaming card for cheap.

Again, you can't do an OCTOcrossfire setup. The cards only physically have 1 CF cable connector!

What about hextuple? 7990 > 7970 > 7970 > 7990

I remember when they "revealed" this card back in June and it was called a "7970 X2".
http://www.tomshardware.com/news/Powercolor-Radeon-HD-7970-tahiti-dual-Devil13,15939.html

Still can't buy it so I'm not sure what's changed other than the name... Actually, I wonder if AMD gave up on making a reference 7990 with lower power requirements. I suppose the HIS 7970 X2 they revealed in June is also a 7990 now?
http://www.techpowerup.com/167377/HIS-Radeon-HD-7970-X2-IceQ-Graphics-Card-Pictured.html

If i can't buy it now it doesn't exist.

Agreed.  This topic is most certainly still active, OP.

AGREE!

Drooling in anticipation

what will be the MHash of this card..

and how many day's will it take to give back it's ROI?

lets put it this way:

it will hash less then twice the hash of a 7970
it will cost more then twice what a 7970 does

do the math

the 6990 did 400MH better that the 6970

than how do you expect the 7990 to do worse than the 7970?

reread:  it will hash less then twice the hash of a 7970

so what is the estimate?

and how many day's will it take to get back the ROI?

Estimate? The Devil 13 will have 2 BIOSs, that switch between 925 and 1000MHz. A 7970 at 925MHz does ~550MH/s, and at 1000MHz does ~600MH/s.

This puts the Devil 13 at 1.1GH/s, or 1.2GH/s. You could probably get to 1.3GH/s with an overclock. I doubt you could get to 1.4GH/s.

if i wait for the 7990 to release and buy one is it a good idea or not?

nope. buy 5970's right now and don't look back till ASIC

The count down has been over for a while ...

3 Left in Poland, at 1400 usd, I'l just wait a bit more :p
http://www.darmacz.pl/index.php?main_page=product_info&products_id=999&cPath=3_107_282

nvm me that site was listing the amount they ordered not real stock.

Me too!   :P

The countdown to 7990 isn't over until I have my fleet upgraded and see shares accumulating at BTCGuild ~100% faster than before.

I'll give it 10years if it doesn't start losing money before that. About 1.5months ago i recommended, do nothing or get a 7970. After seeing how fast the difficulty has risen just from FPGA i'd say wait for an asic. Multiple competitors are coming out with them now so it seems real, and not some BFL scheme. A 7990 is gonna be useless unless your mostly gonna use it for it's intended purposes of not mining. I got a 7970 at the beginning of august, and it was worth getting it then plus i wanted a new gaming card. Get on the asic train if you wanna mine profitably. It should start in 1.5months. Anyways, when is this card gonna be sold?

Just came out, and already gone!
http://www.newegg.com/Product/Product.aspx?Item=N82E16814131479

Zero interest at that price. It was expected so i'm not surprised.

Considering 2 7970 GHz Editions are ~900, 1000 isn't THAT horrible. That said, I wont be getting one.  ;)

Not to mention how late they came out in the year. I bet they still hold their resell value for quite awhile. Interested in seeing someone watercool one and hash it to the max. Not interested in purchasing one.

Well, I guess it's time to close this thread.
And wait for Other companies to make some I myself look forward to seeing if XFX can make one

XFX 7990 DD would be boss!

The card is in stock today.

Annnd, they're gone.

I bought one.  Should be arriving on Friday.

Na, but I got a pair of water cooled 6990's for sale :)  Low mileage, driven by a little old lady from Pasadena.

I work in Pasadena. I know how those little old ladys drive.

Haha Touche!

Did your 7990 come? What Mhash are you getting?

Yes, and it's still sitting in the box.  I kind of don't want to bother with it if I can't get a water block for it.

I'm debating on whether or not to keep it, since I can't find anyone even committing to making a waterblock.

Ah, okay what price would you still it for right now

Hmm... probably 90 BTC shipped in the US.

Better sell it before its month or two of being top dog is over ;) I smell 8990s!

OH gosh will that one be even more anti-climatic release? :)

I'd think about that price if you provide some hashing results that are favorable

I haven't mined with it... just took it out of the box to flip off king_pin with then put it back in. 

ok maybe it hashes at 3ghash and you're keeping it a secret

Or maybe it hashes at 1.1GH/s, like the numbers say it would.

HAHA i just saw em

fuck me again

yea nVidia bought them out.  I've still got my Voodoo 3500 and it still does a decent job at video capture.  Been thinking of posting it on Ebay or the like to see if anyone would want to have a piece of history.  I'm somewhat of a hoarder though and have the voodoo and a 1GHz Slot A athlon hooked up.  Just don't use them anymore. *sigh* 

does the mobo count this as one card or two?  meaning could you put 6 or 7 of these on a mobo or no?

don't know what you're asking. I've heard software can handle 7 or 8 cores. so 4 of the 7990's should run

$1,000 each:
http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007709&IsNodeId=1&Description=7990&bop=And&Order=PRICE&PageSize=20

Right, but using riser cables could you physically put 7x 7990s on a single motherboard and would it allow it.  If so would the OS see 7 cards or 14 cards

in theory the os would see 14 x 7900 cards.


will it show this many is to be determined.


I see it a issue going past 6x 7990.

thats 3 cards. there's issues going past 6 cores

And not to mention $1k for 1ghs per card. Worth getting @ 400-500 yes. $1k? No.

you gotta think of it from a business perspective...

mine on it for a few months...sell the games, then sell the card after u get a few btc.

the 7950 is a better value at $300 600+ mhs and you can resell the 4 games

obviously.  we are talking theoretically.

but we should consider resale value as well

I didn't get any games with my 7990 sapphires.. :(
