I'm stuck between ordering a couple BFL singles or just waiting for the 7990.  Grr..
7990 of course.

I just wish people would dump those obsolete 5970s.  I mean 5xxx vs 7xxx.  That's like 2000 older.  What ever happened to gamer "street cred"?

Do you smell cheap 5970 cards, DAT? Grin
5970 cards are positively ancient, sell, sell, sell!

Just saw a few new 5970's for $350. Maybe they will go with independent water cooling on the 7990 like the pny gtx 580. That would be great for mining. Not sure how else they plan to get any better cooling on the board.

I am still waiting for the GK110 dual-GPU card from Nvidia.

Had enough of AMD and their crap. No 7990 for me.

I'm just praying that Kepler will not suck for integer operations ...

I just hope it comes out cheaper than the expected $850 due to 7970 price drop thanks to the GTX 680 coming out next week.

$850 is pretty cheap. A lot cheaper then 2x 7970's.

about the same as a bfl single

  Darn beat me to it Wink

  I wouldn't doubt any less than $800+ range.  Would likewise probably think it'd still break 1GH though with both cores even at 850mhz. 

Oh Loaded, who art up in Mt. Gox, hallowed be thy name!  Thy dollars rain, thy will be done, on BTCUSD.  Give us this day our daily 10% 30%, and forgive the bears, as we have bought their bitcoins.  And lead us into quadruple digits

1 GH/s should be easy.

7970 gets ~0.6 MH/s per Mhz.  A 7990 clocked @ 850 Mhz should be ~500 MH/s per core or 1 GH/s total.  A small overclock to 920 Mhz would net ~1.1 GH/s.  A large overclock to 1000 Mhz would be ~1.2 GH/s.  Honestly I don't see clocks being pushes higher than that not with the thermal limits of single chassis and the current limits of 3 phase VRM (vs 4 phase for 7970).

That sounds good to me. Might be worth water cooling them.

Things have gotten rather quiet with news on a launch date for the 7990. AMD announced their Q1 earnings already, all that is mentioned is that they have GPUs from the low end to high end consumers in the 28nm process.

Circulating rumors for the most part suggest AMD has insufficient coolers for a 7990, the 7990 might be skipped and replaced by Tenerife (an island in Atlantic Ocean, not a Southern Island), or the possibility of yield issues.

What we are not hearing about is the possibility of faulty yields.  A number of users in tech site forums mention their 7970 DOA and RMA'd multiple times, their 7970 cannot boot, driver crashes and BSOD resulting in RMA (not known with certainty if driver or hardware, but replacement works properly).

I have experience similar issues with Sapphire 7970, having to send them cross country to CA for the fifth time now; Sapphire would not state what issues they found, or if 7970 issues are common, they (Althon Micro) just ship out another card hoping it functions properly.

The 7990 was predicted to launch on Q1 according to AMD roadmap, a MSI slide reveals TBD in Q2. We are in Q2 now, yield quantity appears to be a problem for many companies, but was the 7990 being labeled as TBD for faulty yield reasons (not enough working yields to make dual GPU boards). nVidia is supposed to be launching something important in the next few weeks, possibly a 690/685/670. One would think something might be going on wrong with AMD.

Why is anyone suprised at all Huh

We all knew you can only scale a process up to a certain limit ... or maybe AMD thought their silicon just like their crap drivers could defy reality Shocked

Graphene FTW. Nvidia at least waited until the yields stabilized a little bit unlike AMD which rushed to deliver a product way below the GTX 680 in terms of gaming and everything else.

Too bad Nvidia folk are sleeping and not noticing the mining community Angry

This is information I have stumbled upon and retained over the past weeks since mid January. I was simply asking if anyone has any insight for the delay, given we are already in the second quarter of this year (Apr-end of Jun), the business insight that is; AMD's competitor is starting to release more GPU products, AMD has reduced its pricing, the 7990 remains delayed after Q1.

News on the Q1 earnings were just released, finding them on Google news should be fast.

Insufficient coolers  has circulated here in the forums, this topic has a source, including for Tenerife, yet can be Google'd. Yield issues have been reported extensively for 32/28nm for a number of months. Google will pull up quite a large number of sources, there is consistency.

As for the possibility of faulty yields, there is no mention of this matter, which is why I raise the question if the issue exists. I guess I did not word it as a question in previous post. I will not cite the sources for issues, since they can be found/Google'd for quite easily in tech websites and customer reviews altogether. For Sapphire's RMA service, they tell me to return the card to investigate my issue, for every RMA this year I get no reply on the nature of the problem, its frequency, or cause, just a new card every time around. I have had more issues with 7970 than previous AMD cards, far more RMAs done, and more RMA RMA'd boards sent back (no abusing on card). The signs paralell what other users have reported on the internet: cannot boot, driver crash/bsod, and doa. This is why I am wondering if faulty 7970s are common? If so, a dual Tahiti gpu would probably be affected, and delayed, no? [unless the lottery for a perfectly working GPU is not playing well for me this year so far  Sad]
