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.

Before you do that though, you should test Ryzen with the Ti. Reviewers everywhere are showing that for whatever reason, Ryzen shines with the 1080 Ti at 4k.just4U - Friday, March 10, 2017 - link
I did a double take there as I actually thought you type pull a rabbit out of my a... Was like ... wait, what?? (..chuckle) Anyway, good review Ryan. I read about the Ti being out soon.. didn't realize it was here already.Drumsticks - Thursday, March 9, 2017 - link
Nice review Ryan.I can't wait to see what Vega brings. I'm hoping we at least get a price war over a part that can sit in between the 1080 and Ti parts. I would love to see Vega pull off 75% faster than a Fury X (50% clock speed boost, 20% more IPC?) but wow that would be a tough order. Let's just hope AMD can bring some fire back to the market in May.

I'm also extremely interested in seeing what Vega brings as well. My wallet is ready to drop the bills necessary to get a card in this price range, but I'm waiting for Vega to see who gets my money.ddriver - Thursday, March 9, 2017 - link
It will bring the same thing as ever - superior hardware nvidia will pay off most game developers to sandbag, forcing amd to sell at a very nice price to the benefit of people like me, who don't care about games but instead use gpus for compute.For compute amd's gpus are usually 2-3 TIMES better value than nvidia. And I have 64 7950s in desperate need of replacing.

That's a lot of 7950s. What do you compute with them?A5 - Thursday, March 9, 2017 - link
Fake internet money, I assume. And maybe help the power company calculate his bill...ddriver - Thursday, March 9, 2017 - link
Nope, I do mostly 3D rendering, multiphysics simulations, video processing and such. Cryptocurrency is BS IMO, and I certainly don't need it.MajGenRelativity - Thursday, March 9, 2017 - link
I'm assuming you do that for your job? If not, that's an expensive hobby :P
