It even comes with a little red button. What happens if you press the little red button?  |

So...about that 7990. Some rumors point to 7970 x2 cards being released ( http://uk.hardware.info/news/27987/amd-allows-partners-to-create-hd-7970-x2 ); either way, even if a 7990 or 7970 x2 is released both would be pretty neat for a mini itx setup. Although, haven't the x2 cards been buggy in the past (such as Powercolor cards)? Wonder how they compare: 7970 x2 at 925 MHz(?) vs a 7990 at 1GHz for overclock headroom. |

Didn't we talk about it in another topic? I don't think we did? TDP envelope as well as current leakage at +80C being issues. TDP being a problem? Unlikely. Current leakage? Probably. But NVIDIA's cards shouldn't fare much better there, being based on the same TSMC 28nm HP process. becoming quite common to have doa/failing cards with the 7970s, this through various newegg/amazon/and tech website threads. This is the 7990 killer... It's not going to kill the 7990 since it can't mine for worth shit. The 7990 (whenever it comes) will probably be a "free" card after about 12 months of mining, whereas the NVIDIA card will be only worth its resale value. I'll bet the 7990 will hold its value better too, since it'll be super-efficient and all the miners are going to want it, keeping the demand up. At this point I'm going to guess GK100 is going to be Tesla/Quadro only. Was referring to the title for the 7990. This is the most expensive graphics card launched though, I guess reviews will pop up soon. They used a lot of metal in this design, wonder how much it weighs. Probably will radiate heat well, but it should also retain heat, in addition to the fan/air flow design in a case? Edit: The 690 uses Mg alloys, the exact one is not mentioned. |

There is also the possibility of bad quality chips coming through; becoming quite common to have doa/failing cards with the 7970s, this through various newegg/amazon/and tech website threads. Who knows what is the hold up. This is the 7990 killer: http://www.geforce.com/whats-new/articles/article-keynote/ |

Firstly, I don't think 1250 MHz for a 7970 is safe or maintainable for long periods without electromigration taking a toll on the card.
Secondly, I think they will launch 7990 in May.
1250 MHz core that is under a full 7970 waterblock I meant to say; at stock voltage for 24/7 between 38 to 45 C (above ~1260 MHz, and you need more volts). Under a waterblock, 1300 to 1375 MHz is probably the upper limit (brief test: ~880 MH/s), sounds like a terrible idea to run at such settings for 24/7. Electromigration would probably be more of a concern on an air cooled 7970. |

Many user compare measurements at the wall via a kill-a-watt, then subtract further to isolate graphics card wattage. How accurate are the sensor readings in GPU-Z and HWiNFO64? Is using a multimeter any better (being careful with probes, not to short anything)?

Its actually quite interesting to get all this insight for such a delay. Since the 680s are already out, it is possible to predict how a "690" would perform ideally, which is why I raise the question on AMD holding out longer with out a dual gpu product. If they cannot make a product that can compete with 690, then what you said would make sense for a delay: the possibility that AMD is looking for higher TDP envelope (and cooling problem & leakage @+80C) or more aggressive binning. Oh well, was looking forward in having a 7990 with a longer career in my rig...  , but dual kepler and big kepler Tesla are coming up soon. I have seen many tech and youtube reviews describing the 680 as slightly better than the 7970, at times the 7970 surpasses in certain applications under certain conditions. Still an odd delay in my opinion (both can be described as equal in a sense). Tech review sites will be on top of the real issue behind the delay in a little while. |

Well, trying to beat a gtx 690 is a rather bad reason to justify the delay, business is the priority, selling the product brings in revenue
In the high end market holding the performance crown is everything and means you can charge a premium. Just look at what happened with the 7970 when GTX 680 launched. Nvidia pretty much pushed the 680 as far as they safely could to make sure it would be faster than then 7970 by a decent margin and can now charge more for it than they should by logic. GTX 680 is essentially a mid range card looking at die size and the card itself and should sit somewhere around/just below the 7950 in terms of pricing (6950 vs 560 TI is a similar situation looking just at the physical cards) Had AMD known about the performance level of 680 they could possibly have been able to launch the 7970 at 1000-1100 core since the headroom is huge atm with the stock at 925. Had they done this they could have stuck to their price premium for a much longer period since 680 vs 7970 performance hadn't been as clear as it is now, and there wont anything else coming from Nvidia except GTX 690 in the near future afaik. That's why it would make sense to wait with launching the card, another thing is that the higher they plan to push the card to beat the "expected" 690 performance, the more aggressive they have to be with binning the 79xx cores and it takes longer to build up enough supply for a hard launch. In this market you either have the performance crown and you get paid for having the "best" card or you sell the second best card in the world cause it has good performance/price, guess where they would rather sell their cards. Yes. The 7970 launched in early January, the only 28nm product on the market, new technology, AMD took advantage of this position, and set a desired price. nVidia countered with their 680 in March, in order to attract sales; there should be reason why a customer would pick nVidia's product over AMD's (market has brand fans and non-brand fans): releasing a product superior to a 7970 is no doubt the focus, despite being a little over two months late after the 7970's launch. nVidia launches their 680, sales decline for AMD's 7970 (though the entire single gpu lineup is already being sold in the market from AMD, nVidia only has its most expensive single gpu card out), so AMD re-prices its products to be more competitive against a now present competitor in the 28nm market. Graphics card do improve in performance from one generation to another, I would be tempted to say at least by 30% (not set in stone), just to throw a number out there for reference. Early launches do pose a risk, the possibility that the competition will tweak/reconsider product specs and later down the road release a superior product (better than 30% improvement, into a competitor saturated market). I am guessing this what you are referring to? I am not an electrical engineer (though I do know a few), but I know clock settings on a chip are specified by a number of factors in its design, my initial reaction in the 7970 being able to operate from a stock 925 to a 1250 MHz range told me they wanted to have headroom that can compete performance-wise with a later released nVidia product. nVidia intends to release their 690 sooner than anticipated according to their road map (originally Q3?), an interesting marketing strategy. Indicating they want to release all high-end/enthusiast cards first (then mid/lower end later), in order to capture back more of the high end-market (expen$ive) that they been shut out from since January (7970). Had the 7990 been released in March (just before or after 680 release), then nVidia would most likely be under more pressure in attempting to establish itself in sales/market share of this generation of GPUs ( again brand fans are the loyal buyers, expanding by luring non-brand fans is important in the market). Long story short, we have a delay for the 7990, something fishy is happening... (it is difficult to slap two Tahiti cores onto a pcb)A new Tesla Kepler is being released on May 14, double the transistor count than gtx 680, nVidia's first move for this generation of high performance computing? |

Well, trying to beat a gtx 690 is a rather bad reason to justify the delay, business is the priority, selling the product brings in revenue; holding out for later is counterproductive (lose potential customers in market): AMD wants to be first in a new generation of VGA cards for a reason, no? Remember Fermi from nVidia? It was delayed, sales were not the greatest, so nVidia later re-launched Fermi a second time; obviously a reason exists for this occurrence. 7990 launching Q3 2012, and not in Q1: AMD has come across some obstacle on this high end product to keep having it delayed. (Why was 7990 put as Q1, then the more recent MSI slide say "7990" TBD?)

I figured it would be yet another delay. A release at practically Q3, there is a reason for this, surely they are having problems with something; faulty yields? |

That is not Newegg.com; it is Newegg Business, not for consumers, but if only it was...

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 ] |

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.

I too came across a source indicating April 17 as the launch date for the 7990. Other sources (e.g. http://www.cpu-world.com/news_2012/2012032002_Radeon_HD_7990_Specs_Detailed.html) points to a launch in April. The price drop of current GPU's is with no doubt paving the way for the 7990. I have searched exclusively through many Asian, American, and European sites using Google ("Radeon 7990 site:.tw" for Taiwanese site results only), limiting publications to the last hour, 24 hours, and week options. There is nothing more precise than March, April, end Q1 or beginning Q2.   |

All one needs is Powerpoint and an imagination. 6000 SPs are not enough, if only, its over 9000!!  |

It is most definitely a fake image. As far as I know, the 7990 is supposed to have a PLX PEX 8747 (Gen3 48 lanes, 5 ports) PCI-E Switch on the board, probably be on the front side no?
(48 lanes...just imagine 3 GPU's...)
