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.

You must not have followed the development of GPUs, and particularly flagship GPUs very closely in the last decade or so.G80, the first "Compute GPGPU" as Nvidia put it, was first and foremost a graphics part and a kickass one at that. Each flagship GPU after, GT200, GT200b, GF100, GF110 have continued in this vein...driven by the desktop graphics market first, Tesla/compute market second. Hell, the Tesla business did not even exist until the GeForceTesla200. Jensen Huang, Nvidia's CEO, even got on stage likening his GPUs to superheroes with day jobs as graphics cards while transforming into supercomputers at night.
Now Nvidia flips the script, holds back the flagship GPU from the gaming market that *MADE IT POSSIBLE* and wants to charge you $1K because it's got "SuperComputer Guts"??? That's bait and switch, stab in the back, whatever you want to call it. So yes, if you were actually in this market before, Nvidia has screwed you over to the tune of $1K for something that used to cost $500-$650 max.

You only spend at max $360 for a video card as you stated, so this doesn't affect you and you haven't been screwed.Grow up crybaby. A company may chagre what it desires, and since you're never buying, who cares how many times you scream they screwed everyone ?
NO ONE CARES, not even you, since you never even pony up $500, as you yourself stated in this long, continuous crybaby whine you made here, and have been making, since the 680 was released, or rather, since Charlie fried your brain with his propaganda.
Go get your 98 cent a gallon gasoline while you're at it , you fool.

Uh no, I've spent over $1K in a single GPU purchasing transaction, have you? I didn't think so.I'm just unwilling to spend *$2K* for what cost $1K in the past for less than the expected increase in performance. I spent $700 this round instead of the usual $1K because that's all I was willing to pay for a mid-range ASIC in GK104 and while it was still a significant upgrade to my last set of $1K worth of graphics cards, I wasn't going to plunk down $1K for a set of mid-range GK104 GTX 680s.
It's obvious you have never bought in this range of GPUs in the past, otherwise you wouldn't be posting such retarded replys for what is clearly usurious pricing by Nvidia.
Now go away, idiot.

Wrong again, as usual.So what it boils down to is you're a cheapskate, still disgruntled, still believe in Charlie D's lie, and are angry you won't have the current top card at a price you demand.
I saw your whole griping list in the other thread too, but none of what you purchase or don't purchase makes a single but of difference when it comes to your insane tinfoil hat lies that you have used for your entire argument
Once again, pretending you aren't aware of production capacity leaves you right where you brainless rant started a long time ago.
You cover your tracks whining about ATI's initial price, which wasn't out of line either, and ignore nVidia's immediate crushing of it when the 680 came out, as you still complained about the performance increase there. You're a crybaby, that's it.
That's what you have done now for months on end, whined and whined and whined, and got caught over and over in exaggerations and lies, demanding a perfectly increasing price perf line slanting upwards, for years on end, lying about it's past, which I caught you on in the earlier reviews.
Well dummy, that's not how performance/price increases work in any area of computer parts, anyway.
Glad you're just another freaking parrot, as the reviewers have trained you fools to automaton levels.

My only interest at the moment is OpenCL compute performance. Sad to see it's not working at the moment, but once they get the kinks worked out, I would really love to see some benchmarks.Also, as any GPGPU programmer knows, the number one bottleneck for GPU computing is randomly accessing memory. If you are working only within the on-chip local memory, then yes, you get blazingly fast speeds on a GPU. However, the second you do something as simple as a += on a global memory location, your performance grinds to a screeching halt. I would really like to see the performance of these cards on random memory heavy OpenCL benchmarks. Thanks for the review!

We may do this in the future if I get some time off from univ work. Stay tuned :)Pontius - Thursday, February 21, 2013 - link
Thanks codedevine, I'll keep an eye out.Pontius - Thursday, February 21, 2013 - link

The Titan is nothing more than a proof-of-concept; "Look what we can do! Whohoo! Souped up to the max!" Nvidia is not intending this card to be for everyone. They know it will be picked up by a few well-moneyed enthusiasts, but it is really just a science project so that when people think about "the fastest GPU on the market", they think Nvidia.How often do you guys buy the best of the best as soon as it is out the door anyway ? $1000, $2000, it makes no difference, most of us wouldn't buy it even at 500 bucks. This is all about bragging rights, pure and simple.

Not exactly. The chip isn't fully enabled.
