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.

LMHO - yes by the time the amd fanboy actually declares his amd fanboyism, amd won't be around anymore....Yes, you're done.

And naturally you're not a fanboy... Dear god... you cannot be that stupid...MrSpadge - Thursday, February 21, 2013 - link
Don't buy it, period.CeriseCogburn - Saturday, February 23, 2013 - link
Another amd fanboy control freak loser.I won't be taking your "advice".

Yup you really DO need to grow up a little. Or a lot. Your choice.CeriseCogburn - Saturday, February 23, 2013 - link
Nope, you crybabies and poorboy whiners are the sad little tropes that need adulthood desperately.Adults earn money and have a grand to spend.
Crybaby children do not.

Looking at the way you're expressing your impotent rage all over this review's comment section you sound roughly old enough to be my son's class mate :)DemBones79 - Thursday, February 21, 2013 - link
Wow... did no one read the first part of this article? I think it's pretty obvious from the price/performance ratio that NVIDIA is trying to scare away all but the most truly insane enthusiasts and the compute-on-a-budget crowd.My guess is that yields are still abysmally low and they're still reeling from the backlog of Tesla orders that resulted from the Titan supercomputer contract win. Given that, they probably do not have sufficient supply yet to meet "enthusiast" demand, so they priced it more into the "you've got to be insane to pay this much for this little" bracket.
Whereas computer scientists and others who could benefit from the compute tech on the card could probably more readily convince their Finance depts. to loosen the purse strings for this as opposed to a Tesla proper.
Don't be fooled. This may be labeled as a "consumer" card, and it certainly is a performance bump over the 680, but it was not brought into this world for the express purpose of playing games.

You people are all lying freaks.A day before this, many of you screamed buy 2x of the top end, and when amd was charging $599 for one, you were all good with that.
Now like stupid crybaby two year olds, you've all copped the same whine.
You're all pathetic. All liars, too. All sheep that cannot be consistent at all.

Stop being so rude and abusive.Take a break. Stand up go outside, take some deep breaths. Stay away from the internet for a bit.
Might do you some good.
