NVIDIA’s GeForce GTX Titan Review, Part 2: Titan's Performance Unveiled
by Ryan Smith & Rahul Garg on February 21, 2013 9:00 AM ESTSynthetics
As always we’ll also take a quick look at synthetic performance to get a better look at Titan’s underpinnings. These tests are mostly for comparing cards from within a manufacturer, as opposed to directly comparing AMD and NVIDIA cards. We’ll start with 3DMark Vantage’s Pixel Fill test.
Pixel fill is a mix of a ROP test and a test to see if you have enough bandwidth to feed those ROPs. At the same time the smallest increase in theoretical performance for Titan over GTX 680 was in ROP performance, where a 50% increase in ROPs was met with a minor clockspeed reduction for a final increase in ROP performance of 25%.
The end result is that with gains of 28%, Titan’s lead over GTX 680 is just a hair more than its increase in theoretical ROP performance. Consequently at first glance it looks like Titan has enough memory and cache bandwidth to feed its 48 ROPs, which given where we’re at today with GDDR5 is good news as GDDR5 has very nearly run out of room.
Moving on, we have our 3DMark Vantage texture fillrate test, which does for texels and texture mapping units what the previous test does for ROPs.
Oddly enough, despite the fact that Titan’s texture performance improvements over GTX 680 were only on the range of 46%, here Titan is measured as having 62% more texturing performance. This may be how Titan is interplaying with its improved bandwidth, or it may be a case where some of the ancillary changes NVIDIA made to the texture paths for compute are somehow also beneficial to proper texturing performance.
Finally we’ll take a quick look at tessellation performance with TessMark.
Unsurprisingly, Titan is well ahead of anything else NVIDIA produces. At 49% faster it’s just a bit over the 46% theoretical performance improvement we would expect from the increased number of Polymorph Engines the extra 6 SMXes bring. Interestingly, as fast as GTX 580’s tessellation performance was, these results would indicate that Titan offers more than a generational jump in tessellation performance, nearly tripling GTX 580’s tessellation performance. Though at this time it’s not at all clear just what such tessellation performance is good for, as we seem to be reaching increasingly ridiculous levels.

On Feb 22, the review closed wtih this teaser:"Wrapping things up, on Monday we’ll be taking a look at the final piece of the puzzle"
Monday was two days ago. Am I impatient? Yes. I am really looking forward to seeing what you have to say about Origin’s tri-SLI full tower Genesis PC.
Did I miss it somehow?

I've been thinking the same thing. While I was waiting I found that Tomshardware has a tri sli titan review up. Maybe Anand will have theirs up today.Ryan Smith - Wednesday, February 27, 2013 - link
Unfortunately it's going to be a few more days. I'm currently out of commission with the flu, so I haven't been able to finish my work on the Genesis system yet.justaviking - Friday, March 1, 2013 - link
Oh, sorry to hear about that.Get well soon.

It would be nice if you could also address TheJian's post.In particular on the reasons for choosing such games instead of those listed and, most of all, if in the future the list of games used will change with at least a part of those more modern ones.
If you made a choice there must be a reason. It would be nice to let us know which it is. Avoiding giving reasons for your choices is a reason for many to have doubts on impartiality and/or professionalism.
Thanks in advance

Dream on, you play as many games as the person you have a problem with.The site is amd gpu biased out the wazoo, and every blind pig knows it. They failed to get a card from nVidia years ago (a certain G92) and it's been open hatred ever since. Same thing happened to Tom's.
I'm sure there are other reasons - I've seen some stated - "the confident and arrogant nVidia reps" was one theme.
The intense "hatred" right now for anyone profitable, especially above and beyond the pined for "take down the giants (Intel and nVidia)" AMD underdog dream of these fantasy activists.
The desire for the "competitive war" to continue so this site has a reason to exist and do video card reviews, thus the failing piece of crap company AMD must be propped continuously, it is after all fully compliant with "self interest" even if it is, and it is, extremely unethical and completely immoral.
So don't expect any answers, and there's exactly ZERO chance fair and equitable is the answer.

Don't get me wrong, the site is great, I've been reading it forever, before it was even on the map, and of course people are human and have certain pressures and personal tastes.That won't ever change.
They have many sections, the podcasts are a recent cool addition for some added flavor, and like anything, especially evaluating tow competing entities, perfection is impossible.

I like this site for GPU reviews. I have always found its review better than those done by many other sites.They are rich in technical description and give many answers many other sites don't even imagine to question.
Or ask and answer only by doing a copy & paste from here, and sometimes even without understanding much of what they are C&P.
The computational tests done here, even in the past years, have not been found anywhere. Others use stupid synthetic benchmark mostly based on OpenCL that require two minutes hack to double their performances or are biased depending on who has sponsored the tests (see AMD and SiSandra Benchmark Suite).
However I have been thinking that the game choice was always "random".
Review after review some good games suddenly disappeared to leave space to others that have not real meaning (i.e. games that do 150+ FPS on high end systems are quite ridiculous to bench). Same for very old games recently superseded by new release. And some games never reviewed at all.
For example, I would like to know games like StarCraft 2, that had big problems with SLI/Crossfire at the time it was published, run now on the latest GPUs with latest drivers. Or games like Arma2 that were unplayable. But I still see Crysis Warhead benches, which is not exacly interesting nor indicative of anything while others already have Crysis 3 benches.
It would also be a good option to add Physx option when possible. For example, with such a beast like Titan many games have enough room to run Physx at high levels. How does that compare with a SLI solution? Or with no Physx at all? How that impact on these GPUs rather than GK104 or older Fermi?
But apart these requests, it would really be nice to understand the choice of reviewed games. Because it is well known that games are good or bad on certain architectures more than others, and choosing only most of those that adapt to one or to another with no apparent reason really makes these test quite cheap with respect to others, like for example those done by Techpowerup like it has been addressed before.
Not answering rally means feeding the doubts. Which for many may change in not being doubts anymore.

i agree that the price of this GPU is really high , one could easily assemble a fully mainstream laptop online with dell at this price tag or a desktop, but for gamers, to whom performance is above price. then it is a boon for themfor more pics check this out

so check the above link for specifications of titan

CeriseCogBurn, you shit from your mouth, don't you? I've owned both nvidia and amd cards, I go for performance and I most certainly do not care about spending. It is not about the company. I don't go around slamming the other team online like the bloody ball-less keyboard warrior you are. Do you not realise that that your comments make you look like those "fanboys" which you go around insulting? Go grab a paper towel to clean off all that shit dripping down your chin, then sit down and try to absorb what I've just said while I'll be off to get my Titan. At least AMD and NVIDIA are capable of producing graphics and computing solutions for consumers worldwide while you, Sir, are just capable of being an asshole right here at Anandtech.
