Message 43585 - Posted: 26 May 2016 | 16:55:20 UTC
Last modified: 26 May 2016 | 16:59:19 UTC

I'm considering replacing my current old and completely insufficient GTX 650 with the new GTX 1080 when it becomes available. I'm also going to bite the bullet and upgrade to Windows 10 to take advantage of DirectX 12.

I've also considered a GTX 970 as a replacement but comparing current price to performance of the two, the GTX 1080 wins, hands-down.

However, I'm nowhere near an expert when it comes to GPUs, and I'm afraid that I may be making a mistake or bad assumptions.

My system specs are:
O/S: Windows 7 Pro (moving to Windows 10 Pro)
Mobo: ASUS Sabertooth 990FX R2.0, PCIe 2.0 x16
CPU: AMD FX-8350 8-core
Memory: 8GB Corsair Vengeance DDR3 1600
PSU: Corsair HX750 750-watt

Does anyone see a problem with a GTX 1080 on my system?

Is it overkill, or will the new board be fully utilized?

Thanks.

Should be just fine, I think some work units are CPU limited to some degree but I don't think that means you wouldn't see improvement from a faster GPU, some people might mention the fact that your PCIE is only 2.0, but that should make little difference in x16.

I think 16gb of ram should be more efficient if you can swing that too. Microsoft just came out saying anything less than 4gb makes Win10 slow.

Right now they are selling both 1070's and 1080's, most are already sold out or on backorder though. You can check the status here: http://www.nowinstock.net/ Just click on the 1080 or 1070 link. Soon though the secondary market will be free to flood the market with their own versions of these and there should be plenty to go around. Some early reports have said the fan noise can be a bit loud as it changes alot, with some aftermarket programs doing little to change that. One manufacturer is coming out with a water cooled one, all in one package, that should solve that problem though. This thread at Einstein has lots of details about the cards and even some links to some sites that were able to test some of the new cards. NONE though did any testing on running Boinc workunits though:

Read through the Einstein thread. Why anyone would buy NVidia cards for running Einstein is beyond me. Maybe the new ones will perform better but I'm skeptical. I run mostly NVidia but that's because I primarily crunch GPUgrid. Have tried them on other projects and generally they're poor performers compared with AMD. Maybe I just haven't found the right project. Are there any other projects in which NV cards perform well?

Installing one now. Titan X were quite underwhelming compared to GTX 980s with GPUGRID long runs on a per core/per clock basis. I have a feeling the GTX 1080 might do the same to the future big-die cards. Slower, but not proportionately so. Might be an efficiency buy (980) over a absolute performance buy (980 Ti/Titan X). I expect GTX 1070 to do the same.

In the UK the only additions that will be available in the next few days (2-4) are founder editions of the GTX1080, and they will cost £619. Manufacturer editions are due in several weeks, up to a month for some. They will cost ~£40 less. No sign of the GTX1070's.

Great find skgiven.


PS. CUDA 8 dev kit preview was released a couple of days back.

Though the provided driver (branch) is not up to date in the massive 1.2GB package so one has to re-install the most recent driver afterwards. (First CUDA toolkit in a long while without up to date CUDA / graphics driver.)

The benefit of NV cards is that they can run CUDA and OpenCL. AMD/ATI can't do CUDA (without a lot of jiggery pokery and then only poorly). For those who mainly crunch here NV is the way to go and you have a range of backup GPU projects which you can participate on with the same device. NV cards are good at POEM also. They might not be quite as good as ATI but they are very close (probably within 20% for equivalently priced cards). They used to be, and perhaps still are good at some of the maths projects but that's not my scene. Compared to AMD/ATI the NV cards are bad at MW and poor at Einstein, but good at POEM and excellent here. Based on the specs very little will change in that respect. Unless there is something specific in the GTX1080 and perhaps CUDA8 for Einstein (who are presently still Beta running a CUDA5.5app) I can't see anything changing there.

The article skgiven pointed out alluded to such compatibility issues. Probably the admins will need a 10xx card in order to iron out the problems.

Message 43676 - Posted: 31 May 2016 | 19:31:37 UTC - in response to Message 43675.

Basically the app doesn't recognise the GPU architecture, so it can't get tasks to run.
It should be a simple-ish task to tell the app what this series looks like architecturally, but there could be other issues too. Hopefully they won't have to wait for the CUDA 8 dev kit to be released to get this range up and going, but some app development might be required to get the best out of this range.
Perhaps in a few days it might be useful to resurrect the Beta queue, for GTX1000 series testing? Won't be getting one any time soon, far too expensive in the UK.

I expect that only Matt and Gianni are able to update the app, so only they could tell you.
For now you can use your GTX1080 at POEM.

Maybe I just haven't found the right project. Are there any other projects in which NV cards perform well?

The GTX 750 Ti's run great on Einstein. As I posted there, my GTX 750 Tis on singles BRP6-Beta work units are averaging 7800 seconds at 60% TDP as measured by GPU-Z, or 36 watts (Win7 64-bits). That is better than any of the AMD cards I have tried (HD 7790, HD 7870) in terms of efficiency (PPD/watt), though it was a while ago and I don't have the numbers. But things fall down with the GTX 960, apparently because the 128 bit memory bus (the same as on the 750 Ti) can't keep up with the increased number of shaders on the 960. I think that may be more or less true with the higher-end cards also, though I would expect the GTX 970 to be somewhat more efficient than the 980 for that reason also.

Both the GTX 750 Ti and the GTX 960 are very good on POEM too, as skgiven noted above, even though that is OpenCl and designed for the GCN architecture. At least those Nvidia cards are slightly more efficient than the AMD cards as well, though I have not checked out the higher-end cards on POEM. And on Folding, while we are on the subject, the Maxwell architecture is the best; I don't think the AMD cards are nearly as good for efficiency there either, even though they use OpenCl cores now.

Both run well at Prime Grid too with Nvidia being faster on some parts and AMD being faster on others.

The AMD Radeon RX 480 is expected to feature graphics performance levels between the GeForce GTX 970 and GeForce GTX 980 graphics card so we can expect some decent numbers from this cost effective solution.

http://wccftech.com/amd-radeon-rx-480-polaris-10-launch/#ixzz4Ak4vlFIn

That is all very interesting, but at 150 watts the TDP is also between the GTX 970 and 980. So AMD is now effectively competing with Maxwell (if you don't need CUDA of course), but I don't see anything that says they can compete against Pascal. It is good to have another choice, and the price is right, but it has to be to compete with year (or two) old technology.

I don't know the AMD cards' credit/watt ratio, but my GTX980Ti can process a Binary Radio Pulsar Search (Parkes PMPS XT) v1.57 (BRP6-Beta-cuda55) task in 1860~2000 sec. By a quick browse on the top hosts list I could not find any GPU (including AMD and NVidia) which can process a workunit from this batch faster than this. Maybe I'm a record holder at Einstein@home too?
EDIT: ok, I know that the user can set the number of simultaneous Einstein@home tasks in their profile for maximizing GPU usage/throughput which hurts runtimes, but I'm not sure if it's worth doing on Linux hosts, and I've checked a couple of such hosts too.

HI,
we expect great performance from the GTX1080 but at the moment we don't have any.
As soon as we have them, we need to recompile the code for them and check it.

At the moment, the app will crash on any new pascal gpu.

Does anyone have a GTX 1080 already?

Will wait for the 1080ti Classified and by that time the architecture issues should be worked out.

I keep hoping to get some news, I know if I don't want for the custom cooled ti version I'll really regret it, but not seeing any news will make the 1080gtx tempting once the prices drop.

Picked up an EVGA 1080 on launch day - silly prices here in the UK.

Cool & quiet - I'm using the Founder Edition in a SFF ..... performance is better than a 980Ti (at PrimeGrid anyway)

Any idea when the project will be able to support these card?....

Thanks.

When they get a GTX1080/GTX1070 to work with they need to recompile the app using the latest CUDA 8 dev kit, then perform some in-house alpha testing and then Beta test it here. Might also be compatibility issues with previous generations which would need to be ironed out. My guess is several weeks minimum but possibly after the summer. Don't know if they can run multiple app versions, but would be best to.

(Anyone interested in buying a GTX 960 or 970? Or even the 980Ti? Send me a PM if so. I'd love for them to go to another cruncher.)

I still shudder when I think of that August crash a few years ago when everyone went off to Majorca. It was a month of disaster. But things have been much better recently, and I hope there have been some lessons learned.

While they probably won’t be of any use here AMD/ATI's RX 480 is due to launch on 29th June 2016. For gaming it will likely compete with the GTX1070 and in crossfire may well outperform one GTX1080. In terms of gaming value it will be a competitive card. Hopefully this will drive down the price of the GTX1080 and GTX1070 but it will also reduce the sell-on value of most existing cards as will the RX 470 and RX460, also set to launch in 2 days.

Message 43845 - Posted: 29 Jun 2016 | 21:49:24 UTC - in response to Message 43842.

The Radeon RX 480 was released today. It's a mid-range card in terms of gaming performance & competitive at the $200 to $240 price.
On the negative it doesn't square up to a GTX1070 and performance/Watt isn't great for a 14nm based GPU. It is however competitive against high end previous generation cards and in crossfire could still match a GTX1070 if not a GTX1080. It's aimed at 1080p monitors but isn't great at higher resolutions. Was hoping for better but it's a bit unfair to be comparing a mid-range card with high end cards. On a positive it should still help reduce NV prices and NV has supposedly leaked some details of a GTX1060. Two RX480's should compete enough to reduce 1080 and 1070 prices. Any remaining GTX900 series cards will devalue slightly too, and any future 1060 and below will have direct competition either with the 480 or the 470 or 460.

I think there's no real competition between AMD's RX480 and NVidia's GTX1080-1070, as they're playing in a different league. Expecting that a mid-range card will reduce the price of a high-end card is in vain. This is like if you would expect that the reduced price of the GTX980Ti will reduce the price of the GTX1080, because two GTX980Ti is faster than one GTX1080. If someone has an SLI or Crossfire capable MB which is more expensive than an MB without this capability, I would expect that this owner would buy the more expensive GPU as well, or even more of them. So I expect that the price of the GTX1080 won't be reduced significantly in the near future. If something could drive the price of the GTX1080 down is the GP-102 chip based cards. But NVidia would be a fool to shoot themselves in the foot, so I expect they will release this chip only in a form of a very expensive Titan XYZ card, just as they did it with the largest Maxwell chip. Perhaps a GTX 1080 Ti will be released before Christmas based on a partially disabled GP-102 chip.

My Gainward GTX 1080 Phoenix GLH card has arrived.

So I've joined the club of the "participants requesting a new app".
I'm offering my help to test the new app when it's ready.
I can also give remote access to the host which the card will reside soon.

My first observations with the GTX 1080 while crunching Einstein@home are the following:
It's boosting to 2025-2038MHz
The Maxwell's memory underclocking problem is present with Pascals
Comparing to the GTX 980Ti @1400MHz:
The power consumption is much less
The processing speed is the same (which is a little bit disappointing, but the E@H app is said to be CUDA5.5 but according to the stderr output it's using CUDA3.2)
I've tried to run single tasks at first, but I've set it to crunch 2 tasks simultaneously overnight.

Running 2 Parkes PMPS XT units simultaneously picked up about 15% net RAC on my windows 10 computer with 980ti cards the last time I ran them, a little bit less on windows xp computer with the 980ti card, with the Arecibo units the pick up was insignificant for both computers.

I see that you got the card running on windows xp computer, did you have to use any kind of trick to do that?

After the first results showing insignificant PPD gain, I've returned to run only 1 wu at a time.

I did just the "usual" trick, but the lines to insert should look like this:

%NVIDIA_DEV.1B80% = Section008, PCI\VEN_10DE&DEV_1B80

and

NVIDIA_DEV.1B80 = "NVIDIA GeForce GTX 1080"

In the UK GTX1080 prices have fallen from between £700 and £800 to around £600. Many factors have contributed to the price fall:
The arrival of bespoke (non-founder) editions of the GTX1080,
Increased GTX1080 availability,
The arrival of the GTX1070,
Competition from AMD - despite the 480 only being a mid-range card when playing games it's 'competitive' in cross-fire against a single Pascal. There is also the effect of promotions (not everyone knows what they are doing) and an AMD fan base.
https://www.youtube.com/watch?v=cVVJPbFRDEc
Then there is the forthcoming GTX1060 which is clearly designed to compete (and presumably outperform) an RX480. When released they will drag down the GTX1070 prices and that in turn will drag down the 1080 price a bit. Even the speculation of the card means that many are waiting for it. To sell to those potential customers now the 1070 prices would need to be more attractive.

Note that IMO two RX480's isn't a good option for gamers, but it's an option and because they are better at some games than others, some people will buy them.

PS. Einstein's Arecibo is CUDA3.2, only the Parkes PMPS XT is CUDA5.5.

Entertaining video. It's good to see closer competition returning to the GPU scene. Regardless of what a few seem to maintain, competition in the GPU arena has always driven prices down. Here's another RX480 video:

https://www.youtube.com/watch?v=nQZkWdWCkwM

Also true of the CPU. Judging from the information on the AMD Zen CPUs it appears that thankfully Intel will once again be under price/performance pressure. Remember even the not that distant past: if it wasn't for AMD we'd all most likely still be running $1000 nasty P4 CPUs with 100MHz yearly speed increases. Whether we're AMD or Intel fans or brand neutral, we should all send AMD a thank-you Xmas card for saving us a lot of money while stimulating increased performance in both the GPU and CPU areas.

Message 43910 - Posted: 5 Jul 2016 | 22:02:43 UTC - in response to Message 43898.

OT. Zen should be very interesting for crunchers, especially GPU crunchers.
It's guestimated they will be ~7% slower than Intel's latest and greatest processors, but that is competitive enough and what interests me is the support for many PCIE3 lanes (possibly 64 for some desktops and twice that on servers)... Having a 5 or 10% faster CPU isn't as important as supporting more PCIE lanes and most people buy a reasonably fast CPU, not the fastest at any cost. If you can add a 3rd or 4th GPU to a mid-range or high end system and not suffer any PCIE loss then that's going to shuffle things up a lot for high end builds, and that's exactly what we need. The presently extreme end Intel based system come with extreme prices and don't have much competition.
The Zen processors are also thought to have very high amounts of cache and might support up to 1TB DDR4. Basically they are designed to facilitate high end 4K/8K gaming and rendering which is where the high end market is/will be. It would also make sense to scale that down to mid-range systems where the majority of gamers exist. So it might soon be possible to support 3 or 4 GTX1080's at PCIE3 without any PCIE loss.
With some high end NV GPU's only using 145W to 180W we might be able to build reasonably high end GPU systems with otherwise medium-high end kit; standard motherboard (just with more PCIE slots) and a med-high end but not extreme end PSU (600 to 750W). Presently most Intel processors (even high end: i7-6700K) only support one card at PCIE3 X16. As soon as you add a second GPU the performance is PCIE3 X8, and a 3rd GPU means one operating at PCIE2X8 and two operating at PCIE2 X4, at which point you start to experience some PCIE related loss, increasing the higher end the GPU's are.
Even Intel's extreme end processors (Haswell-E) only facilitate 40 PCIE lanes at PCIE3. Effectively that means two GPU's at PCIE3x16 or up to 4 GPU's at half X8. While that is good enough for Maxwell's it might not be good enough for Pascals (and we've not seen the best of Pascal yet). Such processors cost a lot($1000), as do the boards and if you are using Titan/GTX980Ti cards then you need a very high end PSU.
We might also be better able to build crunching systems on the cheap; with more GPU's rather than a 'bigger' and more high end system. It might prove to be the case for example that a 3GB GTX1060 is the best crunching GPU in terms of performance/Watt or performance/purchase price or performance/(purchase+running price) and if there are enough PCIE x16 slots or even PCIE3 X4 slots dropping those into a case 'might' be worth looking at, or not...

Has anyone donated any of these Pascal cards to the research team yet or are we waiting on the budget on this project to handle that completely? I am willing to donate towards that if needed. I am sure donating towards hardware is cheaper than shipping it from the USA to Spain.
