There can't be 7970s under there, at least not full ones with stock clocks. There's just nowhere near enough surface area on that heatsink to dissipate 500W, unless there's barbs sticking out somewhere I can't see.

That was my impression as well. The article suggests it might be two 7970s. The bottom of the motherboard has 2 8 pin power connectors (maybe not 680s), 2 6 pin power connectors, equal amounts of RAM on both sides, a certain number of phases just below CPU socket. This board has 2 "16x PCIE buses," each having a graphics card, then a "8x PCIE bus for other uses around the board"; PCIE 3.0 that is. It does have thunderbolt which makes it quite intriguing. That long yellow and silver colored heatsink... curious to know what is below it, and if it can WC. (Maybe the board comes with a contraption that is placed on the unused expansion slots of the chasis?)

It uses 2x HD7970M (m for mobile, it's meant for laptops, so uses less electricity but is also slower) also the motherboard is a concept, it won't be in the shop.

That makes sense, the 7970M is a slower clocked Pitcairn (7870) die, so it would consume a lot less juice. I'd still say it will run pretty hot, that's a big hunk of aluminum but it really doesn't look like a particularly effective heat sink.

So apparently, the little red button activates the second BIOS to run the chips up to 1.1 GHz. Taking this speed, one chip would probably translate to about ~650 MH/s; resulting in a combined result of ~1300 MH/s per card. There is no doubt this card could achieve higher speeds given its design, adding a waterblock could most likely allow it to push even further. Power is not an issue for me, but would love to have a pair of these if price is reasonable compared to a 7970.

Will believe it when I see it. Have fun spending $10-15K for $2K of GPU performance! Smiley Watercooled 7970's is where its at, but I just don't have the guts to void my warranty lol. Tongue

Well, "soon" a lot of things will be arriving: dual 7970 gpu cards, 22 nm, 16 nm, atom transistors (one created this year following Ohm's law), high temperature superconductors, warp drives Grin... It looks GPUs are quite significant in bitcoin mining at the present moment, if ASICs become the dominant method of bitcoin mining, then its case will be proven once it becomes widespread with supply and demand being met, not right now.

Room temperature superconductors have been known for a long time already, the difficulty may be in mass producing them. One such superconductor:
4 atoms of potassium -->c60<--4 atoms of potassium  - makes a crystal that has 0 resistance @ room temperature.

Why would you use a warp drive when you can just fold space/time?  Roll Eyes

For Bitcoin to be a true global currency the value of BTC needs always to rise.
If BTC became the global currency & money supply = 100 Trillion then ⊅1.00 BTC = $4,761,904.76.

LOL, warp drive to sling shot around sun, go back in time to mine out bitcoins (Star Trek of course) Cheesy.  

I am not familiar with which superconductor you are referring to, where did you see that fullerenes (or even graphene) doped with an alkali metal such as potassium results in room temperature superconduction? Graphene/fullerenes doped with potassium do achieve superconductivity, but those temperatures are at about ~40K and below (-235 C or -391 F and below). The highest temperature superconductors at the moment  have a temperature just above 100K (HgBa2Ca2Cu3O8+δ: http://www.sciencedirect.com/science/article/pii/S096007790900321X).

There's several claims on Wikipedia of near RTSC. Of course no one has duplicated these results yet, much less turn them into practical applications.

If someone can manage to create a room temperature (and higher and ambient pressure) superconducting material, he/she would not doubt become rich in a heart beat. Implementing this material even on a 7970 would significantly improve its efficiency (power consumption wise, even in other mining devices). It could probably even drive up overclocking potential without running into cold bugging in extreme overclocking methods.

Yes but I think AMD has given up with 7990 as it cannot compete with GTX 690 at any rate ( gaming / perf ) and mining is small marketshare and they also had thermal issues trying to cool so much heat with only one fan.

Hope I am wrong !

Unfortunately I think you're right.  If they haven't announced it at Computex by now, they're probably not going to at all.  I mean why wait til the 2nd to last day of Computex to showcase it?

Seems like that is the case.

The only options are the 7970x2 from HIS and Powercolor.

I mean why let Powercolor show off the monster before you get to show the 7990 reference model yourself Huh Why let them steal your thunder.

One would think they would first announce normal 7990 then super duper 1000 EURO Powercolor and HIS 7970x2 models ...

Value of 5970s just jumped Grin ?

Seems like all the 7970x2 solutions by the OEMs are good enough.

There really isn't any added-value AMD could add here except maybe binning chips straight from the factory, but it's obvious that is not needed (or the OEMs are binning themselves somehow...)
