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 the thing, it's not a 'consumer gaming card.' It's a consumer compute card. Obviously the price for performance for gaming makes no sense but that's not their target market.ronin22 - Thursday, February 21, 2013 - link
This exactly!It's an amazing card for computing.
I wish I could get one...

In reply to both of your comments, I have to ask this: If that is justification for its price, then why is it that AMD doesn't have their Tahiti cards priced like that and why didn't Nvidia price their previous consumer compute cards like that (GTX 280, GTX 285, GTX 480, GTX 580, etc.)?CommandoCATS - Friday, February 22, 2013 - link
Because this seems like a specialized thing for people who care about compute tasks within NVidia's CUDA universe (and things like iRay, which didn't exist when previous generations first came out).The truth is that in academia and research, CUDA is still the top dog (just do a google scholar search). I'm sure for most gamers, the GTX 680 is the way better deal. However, this is essentially a Tesla K20 for 1/3rd of the cost, so it's kind of a bargain from that perspective.

Exactly right. There is nothing about this card that is a value. The same compute functions were there in the older flagships as well, the gtx 580, 480, 280 etc.Titan is just an overpriced, overhyped trainwreck. Another attempt at a cashgrab on the gullible.

The gullible that have the several thousands of extra they can spend that you don't have and cannot spend.Certainly poorboy feels better after having called his superiors gullible. The jelly is seeping through at an extraordinary rate.

LOLGood you run the 280, and I'll run the Titan, and we can be equal and best friends, and I'll tell you over and over all the benchmarks and games and fps scores and compute tests are lying and your 280 is just as good and the same and you're right and I wish so badly that I was as poor as you and just bought a used 3 gen back nVidia card, but they fooled me, the gullible gamer.

ROFL - aww poor baby, now tessellation and compute is a total loss for amd, too as you conveniently forgot to include the 680, 670 660Ti 660 650Ti 650. hahahahha u people suck.So I can buy 2 amd cards that crash and don't run CF at all 33% of the time, or I can buy the most awesome top card in the entire world of gaming and play all the titles and be just great, or I can buy 2 nVidia cards and SLI them and have every game run except correctly except 1 while amd CF fails often...
I can buy the most stable, fully featured, many more featured nVidia card, or I can buy the dying no catalyst driver writers worth their salt (fired for savings) or left for better waters or headhunted, crashing piece of rotten unsupported glitching amd crap.
$999 looks like a bargain basement price to me. I can hardly wait to own The Shield, too.
Innovation. Awesomeness. New features. Unified drivers THAT JUST WORK.
Features ported BACKWARDS to prior generations.
Cuda
PhysX
Frame Rate Target
Boost
Stable dual card setups
Same game day drivers
Honest company not cheating liars like amd
I BUILT THIS co-founder Jen-Hsun Huang current CEO, a perfect example of the awesomeness of capitalism and personal success and the American Dream in REAL LIFE. lol
( Oh I bet those little OWS activist amd fanboys we have here are shooting blood through every pore)
Why in the world would I buy an amd card ? There's only one reason - to try to save a dying loser in a kind act of CHARITY - and frankly, what we have for amd fanboys is nothing short of the most evil little penny pinching crying whining baby SCROOGES I have ever seen.
So we can FORGET IT when it comes to the amd fanboy rabble here supporting AMD - they support only their own selfish fanboy agenda and psychotic public pocketbook panhandling.
I'd like to thank TheJian for pointing out amd fail coverage, vs the ignoring of the nVidia FINANCIAL SUCCESS STORY:

Don't leave out the biggest "crybaby" of all, yourself.
