Hi, I am posting this thread because I am a bit confused as to why nvidia released the titan z. The titan z is $3000 which is equivalent to two r9 295x2's which will perform better in quad crossfire rather than titan z which is simply just sli. I am also confused about amd's stream processors. Are amd's stream processors equivalent to nvidia's cuda? Do stream processors and cuda have the same function or are they used for different things?

well I can't answer your question on the two GPUs. They have their ups and downs, something I refuse to explain to prevent 'flame' wars. both processors due the same things however CUDA cores are used extensively in a number of programs which are CUDA optimized. AMD's processors are used for their selection of optimized- programs. However I wouldn't pick sides because of this.

idk how your gonna plan on CFing 2x R9 295X2s since closed water loops.
I'm sure there is a significant reason for the price of the Titan Z however idk why because first of all. I don't plan on buying a $3000 card. Hell I could build a pretty powerful rig with that money, same for the AMD equivelant, $1500 is still alot to make a pretty powerful rig. Dedicating that much money on a card is ridiculous unless it's for workstation purposes.

I hope I was able to answer half of your question

Thanks for replying and you answered pretty much what I wanted to know. I was thinking of putting 295x2's in a custom loop when I said cfing. I am not going to get these cards though, I completely agree with you about the price and would much rather build a full pc then spend that much on one component.

cuda and stream have different non gaming pupousies but for gaming, they are essentially the same thing(although the power ratio isnt 1 -1 )
The titan Z i double the R9 295X2 simply because nvidia thinks it can charge that much. The R9 295X2 at 11.5 terraflops is FAR more powerful than the TITAN Z with its 8 terraflops. this is because both GK 110s are underclocked in the titan Z as its cooling power is not double that of a titan black. The hawaii chips in the R9 295X2 are both overclocked due to the cards superior cooling power. PLEASE NOTE: OUTSIDE OF DUEL GPU CARDS the Hawaii gpu in the 290/290X and the GK 110 in the 780/780TI/TITAN/TITAN BLACK are mostly equivlant, and which is better depends on the game being played

Most benchmarks I see other than watch dogs show the r9 295x2 pulling head by quite a bit. Is that just because of the better cooling and higher clock speeds? If the Titan Z were to be water cooled and overclocked would they perform more similarly?

if money was no object, the titan z easily. if money did matter and i had no other choice except to choose between the two, i would reluctantly take the 295x2.

in the real world, i wouldn't want either one when i could just get two regular 780s for roughly $1000 and run them in sli. im not really a fan of sli or cfx but sli runs better than cfx.

YES , that is EXACTLY WHAT I SAID, the better cooling pulls the R9 295X2 ahead

My bad. The titan z pulled ahead when it was overclocked. Sorry neil, I should have looked more closely.

I Sorry if Some already said this...
The titan-z has really exceptional compute/GPGPU performance with al ldem CUDA cores. The Double precision floating point is used in Professional graphics cards so I can see why This Graphics card is available it is still cheaper then the K6000. If that is not important to you then the R9 295x2 is imo the better gaming card.

the quadro has very expensive eec memory and exceptional driver support. if your doing scientific research or creating special effects for the movie Gravity, the extra money spent on quadro is more than worth it when there is no room for any errors in the mathematics. the titan is specifically made for gamers who also need the gpu advantages with professional class horsepower for their "enthusiast" non gaming projects.

How did you come to that I have 3 R9 290s in my rig and my wife has 3 780 and I get anywhere from 15% to 20% fps on BF4 and Crysis3 so show me were sli is better then crossfire.

In the old days due to exteme frame pacing problems, crossfire was almost unplayable, while sli was fine, but that has now been mostly fixed by amd driver updates

With the price drop on the 290x you could get 3 or 4 of them for about that price and put your own water coolers and pump and would be able to overclock them more then having the 2 295x2 as far as the TitanZ unless you use CUDA then it's just a waste besides AMD support Open source software that works and does just as good of a job as CUDA.

kinda old question, but unanswered so i'll drop my thoughts. the titan-z has the price tag double of the 295x2, because it is intended to use for scientific purposes coz it's double precision capabilities. the 295x2 has half or less the double precision, than a titan-z.
