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.

That's all you've got ?Did you at least look at the links, or have a failed brainfart of an idea for a rebuttal ?
No, of course you did not. Another mindless, insulting fool, without a single anything other than of course, and insult.
I would feel better about agreeing with you if you had any facts or even an opinion on anything else.

I believe the review was for gaming machines. In that regard HD 7970s and GTX 680s trade blows as one card is faster in some games and the other faster in some games.So, gamers should pick a card that will perform the best for the games they play.
Microsoft FSX is very old now, yet a person needs a very powerful gaming computer to run it with all of the goodies turned up [with lots of code fixes], including overclocking an Ivy Bridge to 4.5GHz+ [this is because when the game was developed it was believed that Moore's Law was valid and single core CPUs would be running at 10GHz by 2012]. And, yes, FSX was coded for NVIDIA.

Well that is where nvidia's attempted marketing falls apart. Compute in their flagship gpu brought to geforce lineup is nothing new. Now they think they can go $1000 on it, doubling the price.Techpowerup was apt when they said this is the most overpriced video card in 25 years.
Nvidia has dropped the ball here on the price, heck, they have thrown it down the street. Too bad, now they will lose more face with the price drops needed to get these off shelves.

They're sold out, already.So much for you being correct, you're already an incorrect failure.
Nice try amd fansvengaliboy

All 100 of them? :)CeriseCogburn - Tuesday, February 26, 2013 - link
You forgot the k fool.Alucard291 - Friday, March 8, 2013 - link
Proof? :)In any case, please stop shitposting. This is not 4chan or engadget.

They're still sold out, ROFL.CeriseCogburn - Thursday, March 21, 2013 - link
From Anand Brain etc in the current article: " 12:16PM EDT - GK110 in general seems to be supply constrained right now. NVIDIA has previously told us they're selling every Tesla K20 and Titan card they can make""Thank you Cerise, I'm sorry, I Alutard291 was wrong, and you are right. I challenged you and lost miserably. In the future I will shut my lying piehole and learn from you, Cerise, instead."
LOL - No you won't Alutard, you will never be correct.

$4500 from appreciative clients, or a grand from whining disgruntled crybabies ?Hmmm... what should a company do... ?

I think they should take the extra $3500, and let the crybabies squeal and wail and fill their diapers.
