The NVIDIA GeForce GTX 1080 Ti Founder's Edition Review: Bigger Pascal for Better Performance
by Ryan Smith on March 9, 2017 9:00 AM ESTSynthetics
As always we’ll also take a quick look at synthetic performance. As a pretty straightforward and wider implementation of Pascal, GTX 1080 Ti shouldn't offer too many surprises here.
With TessMark, we find that the that the GTX 1080 Ti offers 26% better tessellation performance than the GTX 1080, and 63% better performance than the GTX 980 Ti. NVIDIA has always built their architectures geometry-heavy, and GTX 1080 Ti further adds to that lead.
Finally, for looking at texel and pixel fillrate, we have the Beyond3D Test Suite. This test offers a slew of additional tests – many of which use behind the scenes or in our earlier architectural analysis – but for now we’ll stick to simple pixel and texel fillrates.
As it turns out, the pixel fillrate results for the GTX 1080 Ti are a bit surprising. The GTX 1080 Ti doesn’t dominate by as much as I would have expected given the massive memory bandwidth advantage and additional ROP throughput. Not that a 25% increase over the GTX 1080 is anything to sneeze at, but I wonder if we’re looking at one of the consequences of the unusual way NVIDIA has cut-down GP102 for GTX 1080 Ti. We haven’t seen NVIDIA disable a single ROP/memory channel at the high-end before in this manner.
As for texel fillrate, the GTX 1080 Ti excels. In fact it does a bit better than I’d otherwise expect based on the specifications. This could be a sign that GTX 1080 is a bit bandwidth limited at times when it comes to texel throughput, as that’s the facet of performance the GTX 1080 Ti has improved upon the most.

Also, granted, there are some amd optimized games, albeit few and far in between. But that doesn't excuse what nvidia does, nor does it justify it.Besides it was nvidia who started this practice, amd does simply try its best to balance things out, but they don't have nowhere nearly the resources.
amd optimized games are so rare, than out of my many contacts in the industry, I don't know a single one. So I cannot speak of the kinds of terms amd offers their assistance. I can only do that for nvidia's terms.
If amd's terms for support are just as exclusive as nvidia's, then amd is being guilty too. But even then, that doesn't make nvidia innocent. It makes amd guilty, and it makes nvidia like a 100 times guiltier.

What terms? Are we back to "If we help, you cannot optimize your game for AMD"? How do you know there are such terms?Also, you said the entire helping out thing is illegal, terms or no terms. Now it's illegal only if there are certain terms?
ddriver - Friday, March 10, 2017 - link
Read the reply above. nvidia doesn't state the terms, because that would be illegal, the terms are implied, and they refuse further support if you break them... and worse... so it is a form of legal briberyand since their drivers are closed source, any hindrances they might implement to hamper your software remain a secret, but hey, there is a good reason why those drivers keep getting more and more bloated

What if is nothing implied? Why are you so sure something must be implied if they're helping a dev? What if they simply want that game to work best with their hardware because it's an important game in their mind and might help sell some cards?We are heavily into guessing and assuming territory.
I'm not saying shady stuff doesn't happen at all, but to think that it happens all the time without exception would be extreme exaggeration.

There is no "nothing implied". It doesn't take a genius to figure what nvidia's motivation for helping is. Of course, if it is an important, prominent title, nvidia might help out even if the studio optimizes for amd just to save face.But then again, nvidia support can vary a lot, it can be just patching up something that would make them look bad, it can be free graphics cards and strippers as in the case of our lad above. I am sure he didn't optimize for amd. I mean that developers don't really care all that much how well their software runs, if it runs bad, just get a faster gpu. They care about how much pampering they get. So even in the case of a studio which is too big for nvidia to blackmail, there is still ample motivation to please it for the perks which they won't be getting from amd.
There is no assuming in what I say. I know this first hand. nvidia is very kind and generous to those willing to play ball, and and very thuggish with those who don't. So it doesn't come as a surprise if most of the developers chose to be on its good side. The more you please nvidia, the more you get from it, if tomorrow you apply for a job, and there is a sexy chick competing for the position, it can get the job by blowing the manager, and even if you would too, he is not into guys. You are not in the position to compete, and it is an unethical thing that wins her the job. U happy about it?

You know this first hand how? You are claiming a lot and providing nothing concrete.eddman - Friday, March 10, 2017 - link
I already listed the motivation. Game runs good on their cards. People buy their cards.cocochanel - Saturday, March 11, 2017 - link
I don't understand your stubbornness. What ddriver is alluding to is questionable practices. In a free market system, fierce competition and all that, it becomes the norm. But it doesn't make it right. Free markets, you know, are like democracy. And you probably know what good old Winston had to say about that.eddman - Saturday, March 11, 2017 - link
No, he's outright calling such partnerships illegal. He claims to have "first hand" info but reveals nothing.Hardware companies working with software studios has been going on for decades. It wasn't illegal then and it isn't now.

Agreed. Had Intel been fined the true value of what it gained with global dominance over the next 10+ years, things would be vastly different in Sunnyvale right now. So much so I would even speculate that Green team's only hope of viability would have come in the form of an acquisition on Blue team's part.
