GM200-310 GPU will feature custom PCB cooling solutions. GM200-400 Titan X available cooling options are a water block or reference blower.

As of now: unknown if GM200-310 GTX980Ti is a (24SMM) full die or 20-23 SMM cut down.

The 980Ti was inevitable and it's design predictable.

A 24SMM would be a 6GB Titan X. It would be competing with itself.
Still think it will have 2688 cuda cores.
While a 225W TDP is possible that's more like the Quadro style - expect them to keep it at 250W.
Core clock will likely be somewhere between 1088 and 1127, but could be higher with a 250W TDP. Whatever, it's the actual boost that really matters for here. Given the cooling options, there might be an increased performance variation between manufacturers implementations.
Wonder if they will stick with 7GHz GDDR5; 5months ago skhynix announced 8GHz GDDR5, but these are no longer listed on their site.
Probably $750 to $800 based on current prices (the GTX980 is still selling at release price and the GTX Titan X has went up from $999 to >$1170). That said AMD/ATI releases will have a say on NV prices.
My only real concern is that the performance might not scale as well (at present) for the GM200's, though it might if you ran 2 WU's on the same card.

Update - Will be 7GHz and 250W.

http://videocardz.com/55566/nvidia-geforce-gtx-980-ti-performance-benchmarks

The GTX980ti launches in ~two weeks. (a new 7.5 CUDA toolkit will also be released) 980ti compute set is C.C 5.2 -- same as Titan X and 980/970/960. The GTX980ti consists of 2816CUDA (22SMM) with 176 Texture Mapping Units. ROPS are either 96 or 88 depending upon GM200 disablement process.

Off topic, Pascal is supposed to introduce 3D memory and Unified memory (CPU can access it) and NVlink for faster GPU to CPU and GPU to GPU communications. These abilities will widen possible research boundaries, making large multi-protein complex modelling (and similar) more accurate and whole organelle modelling possible.

Now the question is: when will 16nm Pascal/Volta be released? 12-18Months? Maxwell overclocking abilities are impressive compared to Kelper. Will 1500-1600+MHz clocks be possible on 16nm?

Looks like NV added 128cores more than I thought they would, possibly suggesting better yields or architecture (no 3.5/4GB issues here, as promised).
While the 980Ti has 37.5% more Cuda Cores than the 980 the base clock (as reported) is relatively low (1000MHz vs 1127MHz) with Boost being reported as 1076 (980's being 1215). However reports also suggest the 980Ti will stick a 1200MHz base clock. On one of my 970's my base clock is 1111MHz, boost is rated at 1238 but actual boost sensors report 1325, and I've had it over 1340 without issue. So it's likely that the boost will be around the same if not better than the GTX980, especially if it has 250W TDP to call on.
That said, the Titan X didn't appear to scale well, performance varied greatly by task type and we know that the 4GB GTX900's can run 2 tasks per card on recent Windows operating systems to obtain greater overall throughput. Haven't seen anyone running 2 or 3 WU's on a Titan X, but I would expect it might scale better in terms of overall throughput (credits) if they did.
As with all the Maxwell GPU's it's likely that you will be able to preferentially tune the GPU; for maximum throughput/performance (credit) or performance per Watt.
Running 1 WU I don't expect the 980Ti to be 37.5% faster than a GTX980, and that's despite having a 384bit bus (the 980's is 256bits), but it might still be one of the choicest top of the range card for here, if you are prepared to run multiple WU's or wait on a possible app update, which might be available with the CUDA 7.5 tool-kit (if there is anything in it for Matt)?
However I would expect it to be at least 90% as fast as a GTX Titan X for here, and possibly more than the core count would suggest (91.67%) and despite the clocks.

http://www.techpowerup.com/212981/asus-gigabyte-and-msi-geforce-gtx-980-ti-reference-graphics-cards-pictured.html#comments

as say skgiven more CUDA cores but lower clocks .. classic from nVidia

just for you I will give one comparison and the story: I bought in early October 2014 this card
http://www.newegg.com/Product/Product.aspx?Item=N82E16814500360
http://www.zotac.com/products/graphics-cards/geforce-900-series/product/geforce-900-series/detail/geforce-gtx-980-amp-extreme-edition.html

in my opinion the best nvidia GFC 980 based, while published as custom design pcb and cooling..

Why? this card is stepping smoothly on the project GPUGrid on 1460-70 mhz on the core .At higher fell work... Results of speed was always on the second place third place behind Zoltan 780Ti and other 780Ti graphics cards on the Linux.. I had it as Main card to win 8.1 ..... sooo
And all this to 60-65 degrees!!!
because nvidia TDP limited to 110, and not as a reference for the 120
As I was reading here Titan X is a big fiasco. Regarding speed on the GPUGrid tasks ..
It only confirms my experiences . -)))

The second part: There is one very interesting and informative web page about this my card
http://www.gamersnexus.net/hwreviews/1666-zotac-gtx-980-extreme-benchmark-review-overclocking

The question is if those GF cards are NO limited 110 versus 120 watts TDP and should I then maybe get on the 85-95 degrees performance 1600MHz with no problems...
  But I think that there is some kind of engineering problem...
It no longer matters card I sold a few months ago. The man who owns a two or three .. yes we live in high society and what or..?

the whole story what im trying to explain is that titan X or 980 Ti for me are unsurprisingly but awaiting nVidia products..

eXa power and others There are only Internet theorists and never owned a a graphics card. All info assessed according to Google ..

980ti MSRP is 649usd. 980 MSRP 499$. Custom PCB (and reference PCB) Hybrid models for both Titan X and GTX980ti will manage GM200 temps (35-60C) during the summer computing ACEMD 24/7 unlike typical +80C core reference blower model.

Estimated current Long run only Maxwell RAC per day (crunching 24/7) including OS variability factors:

1.1-1.4mil for [1] Titan X
1.05-1.35mil [1] 980ti
700-850k [1] 980
550-700k [1] 970
325-450k [1] 960
200-300k [1] 750ti
150-250k [1] 750

GM200/GM204/GM206 Price per core (current MSRP):

-Titan X: 32.5cents (999$)
-GTX980ti: 23 (649$)
-GTX980: 24.3 (499$)
-GTX970: 19.7 (329$) or 18.5 if MSRP is 309$
-GTX960: 19.4 (199$)
-GTX750ti :23.2 (149$)
-GTX750: 25.1 (129$)

GTX980ti offers Maxwell's best price/RAC ratio computing ACEMD. 980 and 970 also provides an excellent price/RAC. Possibly an App (update) improvement will help GM200/204 scaling to further increase RAC.

So anyone have one of the 980ti's on here yet? Was just able to order one today, should have it running by sunday.

But I'm curious how close they are to the titan x here.

Should be >90% as fast as a GTX Titan X.
Cuda core count suggests it will be 91.67% but the bus is the same width (384bit) giving the 980Ti a 9% wider bus to cuda core ratio. In theory that should nudge performance up a bit, probably over 93%. Having 6GB less GDDR5 might also free up a little bit of extra power for the GPU to call on. Bin variation could come into play (boosts) and some models might prove better than others.

The Titan X's performance running the GPUGrid's app was all over the place; it didn't scale well/properly for tasks. Some runtimes were reasonable but a bit less than would be expected given the cuda core count, other performances were poor and there was great variation in performance relative to the GM204 cards (not that we've had many results to go on) - suggesting the app didn't utilize the GM200 GPU well.
So, it would better to compare the 980Ti against the well established performances of the GTX980.

Compared to the GTX980 and going by cuda core count the 980Ti performance should be 137.5%, but GM200 vs GM204 isn't a direct comparison. The GM200's have a greater ROP ratio (small -ve for here I think) while the bus to shader ratio is slightly favourable. The big question is if the app/tasks will scale well, as is.

At present the challenge will be to get the best out of the 980Ti in terms of credit/day. To do that you may have to run 2 or possibly 3 tasks simultaneously and not use much CPU for anything else. The bigger the GPU the more of an impact other factors have on performance.

Look forward to seeing your runtimes.

It did not. I should have read that next day air ships "next business day". Which could theoretically mean it will arrive on Monday or Tuesday. Either way, I'll have it up and running once it arrives. So at the absolute latest, expect results to be turning in by Wed.

The card is up and running, with a boost clock (from factory) @ 1315MHz. Not bad at all, considering the boost clock listed is 1190. Results will start reporting over-night, and temps are sitting at 60C w/ a 51% fan setting @ 1187mV.

This is also with a 780 in slot2 (not running yet). Further, after looking at how fast it's currently crunching, puts a Gerard_FXCXCL in 25k seconds. It's moving at about .004/s.

My EVGA 980Ti SC is up and running - initial impressions are quick and quite cool in my setup; time & returned results will tell more.

I would like to thank all GPUGRID crunchers - who are healing the world one molecule at a time. I appreciate the incredible dedication of resources - offered freely and willingly to (BOINC) noble GPUGRID project. Has the GPUGRID Project ever had an inside cruncher appreciation event in it's history? Or any type of cruncher event? Team events occur outside of the project. What type of event can we have to celebrate the project's crunchers? The performance tab could offer new category types for such an event.

The card is up and running, with a boost clock (from factory) @ 1315MHz. Not bad at all, considering the boost clock listed is 1190. Results will start reporting over-night, and temps are sitting at 60C w/ a 51% fan setting @ 1187mV.

Thank you for reporting. GM200 at 60C pretty good on (air)? 25K GERALD Runtimes are similar to RZ fastest 980. If time permits: Could you comment on the task's core/MCU/BUS/power usage?

Current GM200 comparisons: NOELIA_ETQ_unboun/NOELIA_ETQ_boun performance tab [8] Titan X builds -- 6 are 40 lane PCIe CPU's [5] x99 chipset -- [1] Dual socket Haswell Xeon -- [1] Z87/97 35W T series -- [1] Z87/97 K series. The LC system(s) temperature computing ACEMD: low 30's to mid 40's. GM200's ACEMD temps vary 32C-85C (Liquid vs. reference air).

ACEMD on GM204 is stable at 1.5GHz. GM200 owner forums report >1400MHz(folding@home) and +1.5GHz for 3dmarks firestrike.

GM200 optimal capability yet to be fully realized. (Once the projects scientists GERALD and NOElIA tasks are finalized - maybe an app update appears.) GM200 (WU utilization) is less than optimal. Current WDDM Titan X GERALD runtimes are as fast Petebe's XP 970. Linux and XP is clearly faster by >10% than WDDM. 2 tasks at a time on WDDM OS's = higher utilization. Total tasks crunched per day also rise by 10%* See ETA's "multiple WU" thread at number crunching.

GM200 upgrade path is another year or two away. (PCI4.0/NVlink/HBM2 are a part of Pascal (Volta) technology advancement.)

GM200 thermal energy (BTU output):
1 GM200 GPU (300W) at 24552 BTU/day > 1023 BTU/hr > 17.05 BTU/min > 0.2843 BTU/sec
--- 3/4 GPU's (900-1200W) set-up 75-100K BTU/day ---

Powerful dispersion for GM200's massive die is essential. Efficient disperse control assists in keeping thermal energy from destroying the PCB. +300W PCB's are aided by the advantages of liquid thermodynamics or a very powerful air cooled heatsink. Gigabyte 980ti cooler is rated for 600W. GM200's 6/12GB GDDR5 Controller accounts for 50+W.

An example of adaptive cooling: EVGA's hybrid GM200/204 120mm rad (Pump mounted near PCB with GPU only LC - fan and a metal plate cool VRM/mem circuitry). I've sold (bartered) off spare parts (m2SSD/RAM/HDD) for savings towards the 980ti. Nearly garnered 5/8 of the 980ti MSRP. Having the older pieces paying for new purchases - certainly helps reduce current out of pocket expenses. I'm not sure if I want Galax's HoF or the 8+6pin EVGA Hydro copper or [2]8pin Zotac block.

Linux and XP is clearly faster by >10% than WDDM.

This is likely to be higher with bigger cards.

2 tasks at a time on WDDM OS's = higher utilization. Total tasks crunched per day also rise by 10%* See ETA's "multiple WU" thread at number crunching.

Likely to be higher with the GM200's, so long as you free up sufficient CPU resources. I would try 2 tasks at a time and then 3. If 3 better, then 4 (no CPU tasks).

Would definitely use SWAN_SYNC=1 (and restart).

Going by Localizer's returns -NOELIA_ETQunboundx1 tasks look like they are only 2 or 3% faster on a GTX980Ti than a GTX980, but SWAN_SYNC isn't on and who knows how much the CPU is being pushed?

On my GTX970's these NOELIA_ETQunboundx1 tasks are struggling to push the cards hard enough to keep them interested (GPU0: power 20%, usage 83%, 41C, 405MHz [downclocked], GPU1 power 76%, usage 67%, 64C, 1266MHz).

Huh, I hadn't even realized swan_sync had to be started again. I remember it wasn't needed for awhile. I'll change that when I get back home.

Gerald utilization was around 75%, but the interesting tidbit for me was that the 980ti is doing noelia in around 10k seconds, with my older 680 rig doing them in 18k seconds. Lol
