GeForce GTX Titan Black Edition and GTX 790 Specs Leaked
The specifications of the GTX Titan Black Edition and the GTX 790 have been leaked.
A report from VideoCardz.com indicates that Nvidia might be bringing out two new high-end graphics cards in the not-so-distant future. The cards in question are rumored to be the GTX Titan Black Edition along with the GTX 790. All of the following information is purely based on rumors though, so be sure to take it all with a grain of salt.
The specifications that are rumored for the GTX Titan Black Edition aren't particularly surprising. After the release of the GTX 780 Ti, where Nvidia brought us a fully-enabled GK110 GPU, it was just a matter of time before the GTX Titan would get a successor that would also have a fully-enabled GK110 GPU. VideoCardz.com predicts that the card will feature 2880 CUDA cores, 6 GB of GDDR5 graphics memory that will run over a 384-bit wide memory interface, and all with the same old TDP of 250 W.
The GTX 790 is a bit more surprising though. It is expected to be a dual-GPU graphics card, and is rumored to carry two GK110 GPUs. The GPUs would not be fully enabled, as Nvidia would want to keep its TDP below 300 W. VideoCardz.com expects each GPU aboard the card to have 2496 enabled CUDA cores, making a total of 4992 CUDA cores. Each GPU is also expected to be able to address 5 GB of GDDR5 graphics memory that would run over a 320-bit wide memory interface.
According to the report, the GTX Titan Black Edition is expected to cost $999 and will be released sometime next month. The GTX 790 is expected to cost more than $999 and may launch sometime in March, though a February launch is possible.

Not really, two 780Ti's win hands down.

The Titan seems like a disappointment from this report. Especially with the 780ti classified and the kingpin edition coming.
As far as I know the fp64 cores are all there, they aren't fused off. What limits performance in the 780's is an aggressive underclock that brings fp64 performance down to 1/8 what it would normally be in the Titan or a GK110 Quadro/Tesla, or 1/24 fp32. So I would think it possible to re-enable that performance with a custom BIOS, or something like that, but I haven't seen any discussion on the topic.
This thread speculates that the feature is hardware locked and will most likely be impossible to hack: http://hardforum.com/showthread.php?t=1799150. And even if it could be unlocked, it is still a 3GB card vs a 6GB card which does give it an advantage although I do not know if that affects the DF FP64 performance?
That's interesting because every 780/780 Ti article I've seen that mentions capped fp64 performance says it's a clock limitation and not fused off hardware. Basically the same way they limit Titan's fp64 performance to 1/24 unless you select the driver option. Can clocks be capped in hardware?
Not sure about the framebuffer, but I don't think it would have any inherent impact on fp64 performance, and if it did it would also affect fp32.
Thanks for the link.

True but for some, the extra $400 and a few hundred more watts and pumping out more heat means a 300w $1000 card is pretty dang good. I can't think of much this couldn't run at 1600p maxed out. Which is perfect for me as I have no intention of trying to push 4K for gaming on 28nm. I'll be surprised if a 20nm Maxwell single would beat this dual either so again 4K to me (since it's against my religion to turn ANY setting down), is a 14nm affair most likely. I like installing a game, and just checking every box or option to max things out and see it as they intended from the get go with no worries.
Also I don't think I could run two 780ti's in AZ without driving myself out of the room in an hour. The rest of the house is 72 all day right now (this is AZ's idea of winter...ROFL), but my PC room is 78 even NOT gaming. I really hope Maxwell+Broadwell combo will get me down to the temps of the rest of the house at least while sitting here browsing the web...LOL. If I game I quickly go above 80 and that isn't too comfortable to me. The ducts have already been altered to shove more into this room from two others and I still can't defeat the heat while gaming. If I had two 780ti's (or probably even the 790) I think I'd need a shower after every gaming session
Can't wait for someone to figure out how to die shrink my whole PC...ROFL. This is a great way to save all the GK110's that either won't run full clock or have defective parts in them though. I could easily see buying one for the pro stuff on top of gaming if I was in a colder state
If you thought Titan was expensive surely upping the power this much for the same price is a win all around. That's knocking pretty much $5200 off the pro cards (2x$2600 savings as GK110 K20 costs $3100 at newegg with 2.6ghz memory) and probably comes with faster ram than the pro cards. A smoking deal for broke pro users with a penchant for gaming.
