How come their hardware team didn't realize CPU memory bottlenecks after 4 cores?

Gotta also remember that AMD is gunning for the GTX690, so heat be damned. They'll find a way to be competitive with nVidia. If that means beefier components, then so much the better for miners.
Well sometimes I wonder - Since ATI was bought by AMD I wonder if they are getting a bit more conservative. When's the last time anyone put an AMD processor in a no-compromises performance build?AMD has conceded the no-bars-hold performance to Intel. However, I do consider their purchase of ATI to be one of the smartest things they've done.
GPUs are going to be more and more important as time goes on. Better graphics + OpenCL are going to be more important that anything else.
Just look at the success of their APU series. So what if the CPU part is 10% behind Intel - the GPU portion is 150% better, and at decent power consumption. And with AMD's push for more and more software to leverage OpenCL, it's all working in their favor.
So the future is to leverage GPU power for better performance. Intel can't do that because their GPUs suck balls, and arn't really getting better. Nvidia can't do that, because They only make GPUs. They might have the best drivers, but do they even make any chipsets anymore? They're only dealing with one part of the equation. This, in my mind, puts AMD and their APU development as the best candidate for future innovation.

Hokay. Sorry - Just something I was thinking about the other day.
/rantAMD has blown a superior hardware lead befire. Look at the Alpha acqusition and the development of the Athlon and Opteron and first to x64. They kicked the shiat out of Intel performance wise for a while.
Intel went back to the book and redid the whole design process and came back swinging, both with excellent new hardware and software optimizations.
I expect AMD to do the same here. They have an excellent hardware team that is hampered by poor software and driver development and poor general leadership.
I remember reading that Intel employed more software engineers than hardware. So ya, I totally agree with you on that point.

Keep in mind the gtx680/690 was not the fully fledged kepler chip either. It was going going to be the midgrade chip. nvidia is holding out with higher grade faster parts because the 7970 wasn't the beast they thought it was going to be.
GK104 lucked out. They underestimated it.
GK100 failed. That was supposed to be their high end chip.
GK110 is likely what we shall see in the new tesla's. Most likely won't be a gaming chip. Unless they use the shitty chips that aren't picked for their workstation cards. Still under development though.
GK104 is just overclocked balls to the wall for nvidia. They REALLY lucked out.

What do you guys think would be the hash speed of a 7990, if it came out anyway?
My guess is double the 7970 - seems logical - or about 1.4GHash/s. Seems pretty beefy, for now.

700MH/s per core (at least on a 7970) is with a pretty hefty overclock. I'd say a 7990 couldn't handle the power of 2 cores OC'd that much, not to mention that heat! I'd say prolly closer in the 1000-1200MH/s range, at decent thermal levels.

My impression is that AMD has left it to individual brands to decide whether to offer a 7970x2. Instead, AMD is making official GHz editions of the 7970 with tighter ASIC binning so that it draws the same power but is clocked at ~1075MHz.
Crossing my fingers that the 8000 series will launch before next year. A tweaked GCN should be quite nice.

Anyway, back on topic.
Do you think we could see a reference 7990 ?
ATM I think AMD kicked the bucket and resigned against GTX 690 ...

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

Mis-rememory...it's a potassium buckide - K3C60, the first fullerene crystal superconductor, found in the early 90's, becoming a SC @ 18K.
c60 4-1-4 interspersed with potassium.
Well they could use aluminized brass for the PCB, it's much more conductive than pure copper or aluminum.
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...)

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 !
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
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
?And Asus:D

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.
