It's an impressive piece of hardware. I'm curious what you can make out of it! | |

Unless the existing AMD app somehow works out of the box on an HD7970 and better than anticipated, the researchers would need to have one in the lab to build and test an app on. I'm guessing this year would be better than next year! | |

Test also in MilkyWay and CollatcConjecture and Moo! Moo, MW and Prime Grid dont run as is on a 7970. Collatz appears to be running ok, WUs are completing, am awaiting validation by wingmen to see if it completed correctly. MW and PrimeGrid PPS Sieve fall over quickly - in the first few seconds, so with luck shouldnt be too hard to find out the cause. The 7970s at least run on Collatz - await confirmation of validation - so its likely all will be well in the once there is time to focus on adjusting existing packages to keep things going until GCN can be properly brought into play. See what the next couple of weeks brings .... Regards Zy | |

just curious what driver you are using. Is it the one specifically for the 7000 series (only for win7 x64 atm)? - http://support.amd.com/us/kbarticles/Pages/radeon-7900-series.aspx | |

The AMD runs dp at 1/4th the sp speed, whereas GTX580 (and brothers) is artificially crippled to 1/8th the sp performance in dp. MW uses dp exclusively, whereas GPU-Grid is completely sp. | |

Hope you get the hold of one soon and can build an app around GCN. What info do you have on its power requirements, and board size? Those are probably the most important items that will determine whether I get one. | |

Is it the one specifically for the 7000 series (only for win7 x64 atm)? - http://support.amd.com/us/kbarticles/Pages/radeon-7900-series.aspx Yes, thats the link, its the 7XXX driver that AMD point you at when going through their front page driver downloads. At present you end up on that 7970 speific download page to download it. So far so good - its running the MW NVidia OpenCL app in +/- 52 seconds settings @1115/300. Runs nice, very quiet, temps on my box are +/- 74 degrees fan on auto, and air exiting from the box is lukewarm at worst, runs very cool. Utilisation on the app is 99% on both the 7970s running in crossfire. Its looking like the scaling is very good, early days, need some more comparitors, but its way way different from the scalling issue on 5XXX. All in All, Its a good start right off the bat with no tweeking, running what is essentially an NVidia app. Matt at MW will get a 7970 shortly, so we shall see how it goes once he gets a chance to get stuck in.

Hope you get the hold of one soon and can build an app around GCN. Board is nothing special - todays "standard" boards will run it. If buying new make sure you get PCI-E 3.0 lanes - not essential now, but will be useful over the life of the board. It runs fine over PCI-E 2.0, its not an issue or performance hit. I am running two 7970s in crossfire inside a small Lian-Li Armorsuit PC-P50 case, MSI 890FXA-GD70 motherboard, 1090T @3.6Ghz, 16Gb RAM @1600mhz. Runs smooth as silk, no issues. I also have a 3960X full tower case, Rampage IV Extreme E-ATX, but its has 2x5970s in it and I am not messing with that, its slated for the 7990s when they come out. The 7970s stay in their long term home where they are. Its drawing around 215w if going at full stretch 1125/1575 and power slider at max +20% so if any 5XXX or 6XXX or 5XX card runs on an existing board, 7XXX will run without exception, and at a very significant power saving. I would say I am running at about 180w power draw on the card as I am not hitting it full stretch at present. The 215w is worst case no external voltage overclock, the absolute well stretched full blast all overclocked power draw with external voltage applied - the whole nine yards - is around 255-260w. Real world non overclock use around 180-215w. Budget for 300w, and that is way overkill giving a nice margin for use and max efficiency in the PSU. A bland real world budget figure for all us mere mortals not slamming with a mega overclock or LN2, is 200w leaving no margin. Power draw is a non issue, I guarantee it draws less than existing similar class cards, so no hidden additional cost - no special motherboard either, nor CPU. Discount all that, if you are satisfied with performance levels, go buy one, there are no associated additional hardware factors lurking in the background - other than a significant power saving. Anyone with bottle-neck worrys, read the review below which essencially says if you have a modern 4 core class CPU as minimum, real world bottle necking doesnt exist. http://www.guru3d.com/article/radeon-hd-7970-cpu-scaling-performance-review/ EDIT: There is a case that says wait for the 1.5Gb card memory versions. The first release cards are all full blown 3Gb GDDR5 memory to give performance on very high res triple/six stacked 2550x1440 monitors for power gaming & multi panel monitor needs. If there is no requirement for that, some will not need 3Gb, so the 1.5Gb cards will be just the job, cheaper, and no performance hit. I have no idea when the 1.5Gb version are due, or which 7XXX variants they will apply to. Milegae on this is subjective of course, as its dependent on poersonal use, aims and intentions. But its a nice option for AMD to put out there. Regards Zy | |

Lots of positives raised about the 7970. So I won't go there :)
It's likely that AMD will have a refresh/interim series update that uses XDR2, probably after NVidia's release. Existing apps still run well on existing 5000 & 6000 series hardware. The apps will probably have to be developed/enhanced (mature) to gain greater performances for the 7900series.

So, AMD just told us that they cannot gives us even one card as they have sent everything to retail. So, we don't expect to have a card soon. | |

AMD just told us that they cannot gives us even one card What a Pity! At £440 ($550/499Euro) they are not cheap. The 7950 is reportedly due out on 31st Jan, but it's still likely to cost around $449 (~410Euro). I think the lesser AMD 7000 GPU's are due out in Feb, but if they are not GCN they won't be any use. Hope you asked NVidia too; their GK-104 Kepler isn't far off. ____________ FAQ's HOW TO: - Opt out of Beta Tests - Ask for Help | |

@Zy: my unlocked HD6950 @ 900 MHz ist jsut as fast at MW as your HD7970, although I'm running the "native" CAL app, of course. And I don't think I'm drawing more power while doing so, the entire rig draws < 300 W off the wall, with an i7 @ 4.0 GHz crunching on 7 other threads. | |

Yup - as you point out its the effect of OpenCL apps. I reckon that will be more widespread as OpenCL takes hold over time - red or green team - but for now it has a greater impact on perception. | |

Their OC at stock voltage is cool (but hey, anyone can do this ;). However, for 1.26 GHz they need 1.30 V - that's massive! The last time I applied that much to a chip 24/7 was at 65 nm :p And my Cayman hums along nicely at 1.10 V. | |

If all goes well, there are good chances that we will be able to provide a new AMD application very soon for all type of cards which are supporting OpenCL, not only GCN. We are already testing now. | |

Lol | |
ID: 27484 | Rating: 0 | rate: / Reply Quote | |
Lol anyway, even if inefficient, many users have requested an amd OpenCL app. Maybe, as in einstein, even if inefficiently, that app could take the top spot (and in the meanwhile you can always improve your code...), thanks to the extreme performances of GCN computationally wise (much more than Kepler, btw, if you're honest - just GK110 can be comparable but it does not exist in any consumer card for the moment). But it seems that here the devs are absolutely not interested. And this is a pity. | |
ID: 27485 | Rating: 0 | rate: / Reply Quote | |
But that app has the top spot because the 1 other person there, who would blow past the other guy, is on Linux. | |

But that app has the top spot because the 1 other person there, who would blow past the other guy, is on Linux. OpenCL is a language. It cannot be strong or weak. The problem, maybe, is that so many very well developed libraries exist only for cuda. And many devs have an expertise only in that language. And also the tools were much more developed for cuda, from the compiler to the debugger. Things have improved dramatically, but here it seems that they're never interested. Every gen that comes out they say: this is the perfect one, we will look into it. They also said, once, "we have an app ready, please enable beta". But nothing ever happened then. No real exchange of true informations. I'm sure that in this community there're also some good programmers. Just release the code opensource and someone can also help you. | |

You got the point, cenit. First time I asked for an app for ATI-cards the HD5xxx series was state of the art. When the HD6xxx series was up to date, they posted, their openCL app is working, but performance is poor. But still no beta apps. Now we have the HD7xxx in the market, next rework (of the GCN) is announced, openCL has proofed to be fast and reliable, and the reaction here: not existent. It was the time when I installed my first HD5xxx card when they advised us to enable beta apps. | |

I gave up the hope for OpenCL-app since the start of donate@home. IMHO the question is: Is it wise to release an APP for AMD, when you can earn money from the performance of AMD at donate? That will canabalize donate, which is only a support project to fund GPUGrid. | |

OpenCL is a language. It cannot be strong or weak. This is not true. Even your next statement disproves it. Every gen that comes out they say: this is the perfect one, we will look into it. They also said, once, "we have an app ready, please enable beta". But nothing ever happened then. While I can recall the developers said that they have an app ready, they said the same time it's not reliable and/or very slow (compared to the CUDA app), therefore it's not ready to release even as beta. No real exchange of true informations. I'm sure that in this community there're also some good programmers. Just release the code opensource and someone can also help you. According to this post, the code of the ACEMD client won't be open source. | |

That will canabalize donate, which is only a support project to fund GPUGrid. Yes, that is exactly what I have been thinking since Donate was rumored and since Kepler was glorified; now they found an excuse for all AMD owners, as poor as that is, that they gave the volunteers an AMD application to support this project, well, indirectly by running none science related bitcoining at yet another project spoiling the volunteers with credits instead of doing valuable science. The developers are simply too inexperienced with AMD OpenCL, so they blame it on everything else, that is the only thing I can conclude from that. I am not an OpenCL developer, but then again this is not my task, as I am donating my hardware, power and time to a project refusing to adapt to another programming platform than CUDA... This is all I have to say about that. Now the CUDA fanboys are free to call me names, insult me and bash me again, as that is what happens every time AMD owners complain rightfully... :)) ____________ | |

I personally would switch my 7950 instantly after the end of WCG HCC GPU to GPUGrid IF they would run OpenCL. But not to donate (only tested it there in the downtime of WCG last week). It would bring me very much Points (620k per day) but im not a credit hunter, so i want to run extra buyed dedicated BOINC Hardware to science. | |

AMD just put out a new revision of their OpenCL SDK, so we'll be taking another look in the new year. However, based on past experience, I don't expect to see the performance and stability necessary to justify the additional effort. Matt | |

At POEM the OpenCL performance of HD7000 GPUs with GCN increased by ~30% with the Cat 12.11 beta drivers. POEM is probably limited by task switching and data transfers.. but there's been some progress :) | |

POEM is probably limited by task switching and data transfers.. but there's been some progress :) Was that 30% going from 12.8 > 12.11 or 12.10 > 12.11? There was a large increase in performance with the 12.9 beta drivers and consolidated in the 12.10 release, and now another performance increase with the 12.11 beta. The AMD driver guys are busy. The increases were very significant for 5xxx and 6xxx GPUs too. It would be interesting to have a 12.12 legacy release (much like they did with the 12.6 legacy drivers) to support some of the earlier cards. The 40nm 4770 is still a relatively efficient cruncher on some projects considering it's low power draw. | |

From what I heard (don't have a GCN card yet) it's ~30% from 12.8 (or earlier) to 12.11 beta whatever. Personally I've seen a 10% (accumulated) increase for an HD6970 - which is still significant at POEM. | |

I've got two things on my mind: @1: according to performance comparison chart @einstein http://www.dskag.at/images/Research/EinsteinGPUperformancelist.pdf the HD7970 is in the same performance range as the GTX690. If you include power consumption to your personnel comparison it might change your mind. @2: The question amd-app yes or no is a very old question here. The last post from a dev I can remember was: atm the amd openCL has very poor performance but stay tuned and keep the checkbox for beta apps checked. So why should I not come in from time to time and ask about the progress of this question? As MrS posted earlier You're of course welcome to report on OpenCL progress and ask about the current state.. I will do that in the future as I made it some days ago, and be shure, I don't get mad at the developers if no progress is there. Alexander | |

1: The hardware is powerful, I'm sure we can all agree on this. But the VLIW5 and VLIW4 cards have also been pretty powerful.. depending on which code you fed them. | |
