AMD AIB Partners Said to be Working on "HD 7970 X2"
Although AMD has plans to unveil its dual-GPU Radeon HD 7990 some time during Computex 2012, next month, it is reported that its add-in board (AIB) partners will be rolling out custom-design dual-GPU graphics cards labelled "Radeon HD 7970 X2." These cards most likely feature a pair of 28 nm "Tahiti" GPUs with high GPU clock speeds (perhaps above those of the HD 7990, perhaps even over 1 GHz). The new cards could then target the performance levels of NVIDIA's GeForce GTX 690 at competitive prices. It could also be AMD's strategy to give the onus to AIB partners to come up with "off-spec" dual-GPU cards to compete with GTX 690 in terms of performance, while maintaining an "on-spec" Radeon HD 7990 that seeks a higher price-performance ratio than that of the GTX 690.

it will be a tesla add in card for compute
nvidia has to pack a monstrous chip with a bunch of wimpy kepler cores to get the compute power they require
kepler did great in gaming situations there is no doubt in that, but not in compute, thats why nvidia is in dire need to release gk110
on another note amd is totaly wasting time showing off how great hd7970 is in compute when they havent yet released a fire pro version of it -__-
I just dont know what in the world are they doing. i guess amd has no interest in promoting add in discrete cards for compute because they wanna push for HSA platform (thats the only explanation i can think of)
edit: I do have to note that amd doesnt restrict features in gaming cards much like nvidia does with drivers in cuda and double precision and what not, as for amd opencl acceleration is enabled across the board as far as i know as well as double precision operations being enabled in tahiti so i also wonder if that has anything to do, and whether amd will keep the firepro line
Just 2 x HD7970 with SWIFTECH KOMODO block and HD7900-XFIRE X 2 bridge.

"When questioned as to why AMD were launching a GHz edition now, and didn't originally, they explained that yields are now better, their average voltage required to hit 925MHz is much lower than it was on early ES revisions, and most chips are happily hitting 1250MHz now. It's time to let the GPU stretch its legs a little as yields improve"
7990 could use the new 7970 "Ghz Edition" stepping.
7970 X2/7990 X2 sounds awesomer.
pitcairn has 1280core and 212mm2 die size 1280/212 = 6.037
tahiti has 2048 cores and 365mm2 die size 2048/365 = 5.61
and note that both tahiti and pitcairn have pretty much the same front end so in reality tahiti should have a bigger value in core/diesize ratio, but offcourse tahiti does have a wider memory controller but still i dont think its that significant
now lets assume tahiti does have 2304 cores then 2304/365 = 6.31 see that? XD
i wonder if thats the casethis^ tho the higher end 7970 will probably be ghz editionwell with amd claiming yield is way better now they are probably able to get tahiti to run at 925 with much lower voltage allowing for an hd7970 x2
AMD could have it's own Geforce GTX680 based on Pitcairn's GCN design.
