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.
Topic: [AVL NOW] Countdown to radeon 7990 - page 3. (Read 11407 times)
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
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?

what will be the MHash of this card..
and how many day's will it take to give back it's ROI?

Drooling in anticipation
If i can't buy it now it doesn't exist.
Agreed. This topic is most certainly still active, OP.

I remember when they "revealed" this card back in June and it was called a "7970 X2".

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?

I want four of these in quad SLI. Because Crysis.
*orders dilithium crystals for antimatter PSU*
*orders dilithium crystals for antimatter PSU*
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
Extendo PCIE cables will get them hooked up,but the OS using them all could be a problem
Again, you can't do an OCTOcrossfire setup. The cards only physically have 1 CF cable connector!
What about hextuple? 7990 > 7970 > 7970 > 7990
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.

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