New GTX TITAN-Z Launch Details Emerge
NVIDIA's GeForce GTX TITAN-Z missed the bus on its earlier 29th April, 2014 launch date, which was confirmed to the press by several retailers, forcing some AIC partners to content with paper-launches of cards bearing their brand. It turns out that the delay is going to be by just a little over a week. The GeForce GTX TITAN-Z is now expected to be available on the 8th of May, 2014. That will be when you'll be able to buy the US $3,000 graphics card off the shelf.
A dual-GPU graphics card based on a pair of 28 nm GK110 GPUs, the GTX TITAN-Z features a total of 5,760 CUDA cores (2,880 per GPU), 480 TMUs (240 per GPU), 96 ROPs (48 per GPU), and a total of 12 GB of GDDR5 memory, spread across two 384-bit wide memory interfaces. Although each of the two GPUs is configured identical to a GTX TITAN Black, it features lower clock speeds. The core is clocked at 705 MHz (889 MHz on the GTX TITAN Black), with GPU Boost frequencies of up to 876 MHz (up to 980 MHz on the GTX TITAN Black); while the memory remains at 7.00 GHz. The card draws power from a pair of 8-pin PCIe power connectors, and its maximum power draw is rated at 375W. It will be interesting to see how it stacks up against the Radeon R9 295X2 by AMD, which costs half as much, at $1,500.

For 3K USD I expect NOTHING else than overkill.I honestly think that they won't be rated any higher than what Nvidia has been using on reference 780/Titan/780ti, they are almost all the same.
I bet this GPU will blow when matched against 110%+ TDP, but hey we shouldn't overclock our GPUs, right? :)
The Titan Z seems to fall into the chasm between usability and outright performance. Nvidia obviously tried to squeeze as much into a conventional air cooled card as was possible, but it falls short against the competition. AMD have shown in the past that they don't have any qualms about ignoring the PCI-SIG (the HD 6990 and 7990 ), but unlikely that Nvidia expected AMD to put out the first 500 watt reference card, or the first water cooled reference card for that matter. In this instance (the top of the model line) brute force trumps efficiency and Nvidia will be pilloried for being too conservative even if they relaunch the card sans FP64 as a GTX 790. Having said that, I fully expect both cards to enjoy the short and intermittent production runs and free-falling depreciation enjoyed by their dual-GPU predecessors.
The sad thing is that one camp has a $3000 card, and the other camp has a 500 watt card. I'm not entirely sure we're heading in the right direction.;)
Two Titan Blacks for DP make it obsolete, two 780Tis for gaming make it obsolete.
It's just an hype halo w/e product.

There is no requirement for SLI with compute work, so with pcie risers one can build massive GPU array while reducing overall number of systems (less cpu-s, motherboards and psu-s needed) on site.
This card is for companies that are building their own supercomputer.
Additionally marketing it as a geforce product because it runs games beautifully, nvidia would be crazy not to. Promote synergy like a boss and all that.
If you look at EVGA's K|NGP|N edition of the 780 Ti it's base clock is 1072MHz!! Rumour is that EVGA is going to also be bringing out a 6Gb version of that card. The current 3Gb version of that card sells for 859.99 USD from EVGA themselves. A 6Gb version might possibly be closer to 1000 USD buy two of those, Sli, and you'll have all the power you need for quite some time and probably save yourself 1000 USD along the way.
Judging by the initial testing, the card has some headroom. A 1050MHz boost on an unheated board isn't too bad, so either a waterblock or a reworked air cooler with larger fans such as the ACX would be a better bet for maintain that kind of level without having to ramp the fanspeed to max.ECC for GDDR5 isn't really needed unless the workload is of critical importance. GDDR5 already has EDC (Error Detection Code) built in which detects errors across the system bus. The only errors it can't check for is memory IC fault and GPU memory controller errors, both of which (along with GPU runtime validation) are stringently binned for to produce pro cards. It's why a K40 (as BiggieShady mentioned) costs 4-5 timesthe price of a Titan Black, and a W9100 costs 6 timesas much as a 290X

You don't build supercomputers with a card from a gaming stack. Unless uptime, errors and stability isn't a concern.
As for whatever vague point you're making, there are plenty of instances where FP64 could be useful to a prosumer (mixed single+ double precision workloads such as 3D modelling)So, judging by the bolding and price inclusion, you're saying double precision :
Titan Z...0.87 GFlop/$
W9100..0.75 GFlop/$
K6000...0.45 GFlop/$ (the card is available for $3800)
K40.......0.34 GFlop/$
Not sure how that the Tesla, Quadro, or FirePro are supposed to be "saving some money".
Of course, it's still an apples vs oranges scenario. Professional drivers, software (Nvidia's OptiX, SceniX, CompleX etc.), support, binning, and a larger frame buffer (the Titan Z isn't a 12GB card, it's a 2 x 6GB card) should all add value to the pro boards regardless of vendor.
A further point to note is that Nvidia's FLOP numbers are calculated on base clock (which is correct for double precision since boost is disabled) , not boost -either guaranteed minimum or maximum sustained for single precision. The FLOPS for AMD's cards are calculated on maximum boost, whether it is attainable/sustainable or not.
Case in point: The GTX 780 is quoted as having a 3977 GFlops FP32 rate( 863 base clock * 2304 cores * 2 Ops/clock). But GPGPU apps can be as intensive as games. The GTX 780 I have here at the moment - based on that the usual calculation should be 967 * 2304 * 2 = 4456 GFlops. In reality the card sustains a boost of 1085 MHz at stock settings (no extra voltage, no OC above factory, no change in stock fan profile). The actual FP32 rate would be 1085 * 2304 * 2 = 5000 GFlops
A quick Heaven run to show how meaningless the base clock (and its associated numbers) are, and why they generally aren't worth the time to record
It probably depends upon your definition of a supercomputer. If its an HPC cluster, then no, you wouldn't...but that's a very narrow association used by people with little technical knowledge of the range of compute solutions.
Other examples:
The Fastra IIis a desktop supercomputer designed for tomography
Rackmount GPU serversalso generally come under the same heading, since big iron generally tend to be made up of the same hardware....just add more racks to a cabinet...and more cabinets to a cluster...etc. etc.
I'd also note that they aren't "one offs" as you opined once before, as explained here: " We build and ship at least a few like this every month".
Go nuts configure away.
I've been abusing my two graphics cards for rendering, work and fun especially now that you can purchase multiple render platforms that support CUDA rendering.
I personally use Octane CUDA render plugins (3Ds Max and Poser) for my personal enjoyment when I'm free and Vray CUDA for work.
You don't need a Tesla/Quadro card for CUDA rendering :)
I would still purchase two separate GTX Titans (not black cause the difference is minimal) compared to this one. Save one slot for what?
7970... 4.735 GFlop/$
It makes all your number look like a rob. Not to mention 7970 can easily OC more than its default 925 MHz
Few people bought the first Titan for their work with CUDA. However, the others simply bought it because it was the best of its time. They was f*cked really hard by nVi with the release of 780 and 780Ti. Hopefully a smart gamer could learn from their demise and stay away from these stupidly overpriced cards.
Most of people bought Titan for GAMES, and the official drivers of nVidia for this card have been always optimized for GAMES.
And that price for a gaming card is stupidly high.
Sales numbers cannot determine the buying purpose unfortunately. However, you can go to some tech forum to see how those Titan buyers bragged their FPS , just like AMD buyers recently have been talked about the hashrate of their cards.
Crosses fingers for Maxwell's Titan to have 12GB Vram, FULL GPU rendered scenes can reach up the 6GB framebuffer easily as you have to load all textures into the GPU.
