sorry can't find any finnish store that has a 7970 for that $445 price in Dollars I find plenty selling them for £445, in dollars $445 seems to be bellow the company FOB price of ~$475

No finnish store sells in either currency ...

I am sorry but if we are talking about the same thing then you will need to post a link of the place you are buying those under cost cards. When you buy in a different currency they take the numbers of your credit card and Visa, MC, Amex or Disc deal with the currency exchange... but still there isn't a place in the internet that mentions anything about a $445 bucks 7970 they mention a $25 price cut from the base $550 price which retailers don't have to pass on(which newegg gives some when you buy 2+)... but just maybe you are confused about currency we are talking about, the £445 = $704.48 (today's price) not really apples to apples and the 7990 will cost in $ here in america not in £ and $704.48 is 83% of the cost of a single 7990 for half the hashing power. Just saying :p

I'm Finnish, like i told you already, we use Euro, not Pound Sterling.
No, i'm not confusing. They do not accept CCs, only finnish banks etc. Even if you are Finn you can't get that price unless you are a company.
Because Finland has so insanely high taxes we get sometimes subsidized by multinational corporations. For example, many Germans come here to buy their BMW ...

I can sell you some cards for, say 500$ + shipping, i ought to have 2 to sell next week unless mobo, psu etc. for new rig arrives.

?... 850(7990) / 535(7970 on newegg multiple card price) = 1.589 so the 7990 is 59% more expensive than the cheapest 7970, there are lots of them going for $600+, I would venture to say that is quite far from being almost double the price.

Unless you happen to be paying far less per 7970 than newegg pricing Smiley I get new ones for about 445$ incl. shipping, with interest free credit when purchasing them ...



that is very nice indeed, any chance of letting us know where you getting them from for such great price?

It's a finnish store.

Yes, but you could using these have more than 5x7970 on single rig Grin

But mostly they are just curiosities Smiley

I've seen mother boards with 8 PCIe slots, they just cost too much. And for 8 x 7970s you could get 6 of the 7990s when they come out.

I seriously doubt 7990 is only 33% more expensive per card. Try more like 80%.

7970s are damn cheap right now, well for me atleast ...

The 7990s have had their price out for more than 4 months. You can just search for it, in 100% of places that talk about it's always the same $ 850 for the basic reference design. If retailers are going to pad the price some then I don't know.

Exactly like i assumed, that is pretty much double price.

you can't have 6x 7990 running in the same box because that's 12 GPUs. 

Yea I know, I just said that for the money you better off getting the 6 x 7990's vs the 8 x 7970's

This is not OK.
Wait, that would require USB 3.0 on a Raspberry Pi.

Nevermind!

Doesn't Raspberry Pi have some USB interface?
USB is backwards compatible on that direction too, i think.

Yeah, USB 2.0.

Buuuuuuut...

*Could* it be used to add PCIe devices to, say, a Rasberry Pi?

Maybe... maybe...

That's what I was thinking, it would be a limitation of USB, not PCIe.
The links to merchants are on their website, however some are dead. (not a good sign)
Video looked pretty straight forward, though. 

There are three limits.
1) AMD drivers have a hardcoded limit of 8 devices.  AMD has indicated no intentions of increasing this.
2) Unlike NVidia, AMD drivers are hard linked to xorg (or Aero in windows).  They ARE Graphics cards which we happen to mine.  Not general purpose compute modules which CAN be used as graphics cards.  Neither xorg nor windows support more than 8 graphics cards.
3) There is a BIOS limit as each PCIe device needs to be allocated memory.  Foolishly most bioses are working with very small memory range.  Using USB 3.0 doesn't magic away the problem.  This is simply a USB 3.0 to PCIe bridge.  It will be seen by the BIOS as additional PCIe slots which have devices that need to be initialized.

Issue #3 has been solved by custom BIOS.  Issue #2 has been solved by custom version of xorg which ignores the GPUs (doesn't see them as GPUs).  However these have only been solved on NVidia based systems.

AMD hardcoded device limit combined with hard linking to graphical subsystem of the OS is a project killer.  Without AMD joining the 21st century and treating GPUs as independent computing engines (like NVidia does) you won't have more than 8 GPU per rig.
