NVIDIA GeForce GTX TITAN Preview - GK110, GPU Boost 2.0, Overclocking and GPGPU
Display Overclocking and Double Precision Performance
With the GeForce GTX 680 NVIDIA introduced a couple of unique features that weren't directly related to GPU performance. One of them was Frame Rate Target that allowed users to set a maximum frame rate for a game that might be older and not need the full power of the GPU powering your system. Another was Adaptive VSync that enabled a GPU to run with Vsync enabled when going OVER 60 Hz (or 120 Hz on an appropriate panel) but turn it off when dipping below 60 FPS.
Great stuff that improved game play experiences without being directly related to performance.
With the GTX TITAN NVIDIA is doing it again - this time with display overclocking.
With GPU Boost 2.0, we’ve added a new feature that makes this possible: display overclocking. Using tools provided by our add-in card partners, you may be able to overclock the pixel clock of your display, allowing you to hit higher refresh rates.
The implications with this are pretty impressive and I am eager to try out the ability to overclock the various displays in our office and report back with results. NVIDIA claims that this is pretty safe and a simple test will determine if your monitor can handle higher refresh rates. This wasn't enabled in the version of Precision X we were using but hopefully we'll get it working by the end of the week.
Also, because this is a GK110 based part, I can hear the GPGPU users out there salivating over the idea of getting this much compute power for "only" $1000. Good news! All of the double precision capability is accessible in this chip on the GeForce branded card though you do have to go into the control panel and enable the double precision modules.
The hard coded switch is necessary because the GK110 GPU down clocks pretty heavily with DP enabled, and thus gamers would get much lower gaming performance if left on while running Crysis 3, for example.
By default, GeForce GTX TITAN runs the DP cores at 1/8th their full clock speed, and given each SMX has 1/3rd the number of DP cores vs SP cores, the DP operations would run at 1/24 the SP rate, similar to GeForce GTX 680.

Yeah, but will it run Crysis?
We'll find out on Thursday. :)
no
Actually, the better question is: will it blend?
Crysis 3, more like. :) Can't wait to see the performance results!
Might the GTX Titan review be the first to use your new frame-rating performance metric? Can't wait! :)
I can tell you right now that it won't be the full version of our Frame Rating system, but we'll have some new inclusions in it for sure.
I am really looking forward to seeing how this card will perform with crysis 3
I think I'll get one. I have no need for it, but it looks cool. So, from someone who knows very little about computers or gaming, I take it this would be "overkill" to have my buddy build me a new system around this?
Hope to see some GPGPU testing and comparsion to 680. I can assist with Blender3D as it support GPGPU rendering on CUDA cards if you guys want.. Need to find out if I need to start putting coins away for another puchase ;)
Point me in the right direction!
+1 for blender render times! Go to blender.org to download blender (looks like it is down as I post this, probably for v2.66 release).
blendswap.com could be used to find stuff to render. That way the files would be publicly available to anyone who wanted to compare your times to their own. Just make sure the files use the cycles rendering engine (not blender internal).
Instructions at http://www.blenderguru.com/4-easy-ways-to-speed-up-cycles/ can be followed to swap between CPU and GPU rendering.
I'm looking to replacing three GTX580 3GB mainly for rendering. With 6GB memory and the massive amount of CUDA cores I'm really looking forward to Blender Cycles speeds, but also Octane, VRay-RT. This must be one of the usage scenarios for the Titan, rather than pure gaming.
Download blender from:
http://www.blender.org/download/get-blender/
Windows 64bit install is the simplest.
The most common test for GPGPU rendering is to use the link below. "The unofficial Blender Cycles benchmark"

And then use the information provided by Riley:

*shrug* I guess its fun for the reviewer to get something new in the office but this might as well still be a myth as 99.99% of users will never even think about getting something this expensive.
Give us something new that regular people can actually afford...
i agree with above. one of these or two 670? i hope we see that comparison in your review.
670s are too cheap - you'll see two GTX 680s though.
ah the nvidiots will gladly put out $1000.00 for a graphics card that is nothing more than a 680 on roid rage... i know im not touching this card unless i win the lotto and get hit in the head with a brick making me mentally incapacitated.
If PcPer'll have the time and blessing of Nvidias highers and Geekbox Gods, make a review with a system comprised of these cards in sli and dual Intel Xeons and/or AMD Opterons.
Sweet mother of GOD!
I want! I can't wait to see the benches. They outta make Titan version the norm for future generations to bring down the x80 series lol.
It would be nice is someone would test this card with blender 3d to see how it rates for rendering against the Quadro GPUs that cost way more! Does anyone know of websites that benchmark open source software using GPUs, as most of the benchmarking sites are using Maya and other high priced software, and little opensource free software for their tests.
ALL that POWER from one Card, shame about the price. This is is my Adobe Premiere Pro and After Effects dream card, plus gaming! Too bad for the price.
Anyhow, a lot of great features, cant wait for the review, great informative video Ryan!
I wish NVIDIA had been a little more aggressive on the price but I still couldn't have afforded it. Just upgraded both my and my wife's system to 7970 GHzs because the bundle deal was too good to pass up.
That said, for all the people who say cards like this are overkill, my current Skyrim install would give this card a run for its money even at 1080p60.
Can I mount a 4-way Titan SLI?
I don't know, that sounds uncomfortable.
AMD here is your competition, What do you have in mind.
"NEXT GENERATION" gameplay AMD!
This graphic card is going to pack a punch people!!!
What is this? Lucky i got a ps3 last week! it looks better and pre ordered crysis 3 and it has blu ray so its better graphics!
Lol... the sad part is there are some people who actually believe that.
The sad part is people who go from SD to HD and see no difference.
i will take out a loan to buy this card! :)
