The NVIDIA GeForce GTX 980 Ti Review

As always we’ll also take a quick look at synthetic performance. Being a virtual copy of the GTX Titan X, GTX 980 Ti should perform very similarly here, just as we've seen in our gaming tests.
Compared to GTX Titan X, GTX 980 Ti does technically lose 2 Polymorph Engines as a result of losing 2 SMMs. However as with our games, this doesn’t really hinder GTX 980 Ti, leading it being within a few percent of GTX Titan X on tessellation performance.
As for texel and pixel fillrates, the results are both as-expected and a bit surprising. On the expected side, we see the GTX 980 Ti trail GTX Titan X by a bit, again taking a hit from the SMM loss. On the other hand we’re seeing a larger than expected drop in the pixel fill rates. GTX 980 Ti loses some rasterization throughput from the SMM loss, but a 15% drop in this test is much larger than 2 SMMs. Just to be sure we checked to make sure the ROP/MC configuration of GTX 980 Ti was unchanged at 96 ROPs, so while we can explain 10% or so (GTX 980 Ti doesn't have its clockspeed advantage in such a short test), we're at a loss to fully explain the last 5%. The short run time of the test also makes it more varaible than other tests, so that may be the last 5%.
Though in either case, despite what 3DMark is telling us, we aren’t seeing any signs of GTX 980 Ti struggling at 4K versus GTX Titan X. So if there is a meaningful difference in pixel fillrates, it’s not impacting game performance.

@zepi: Perfect scaling on non-Intel's fabs doesn't exist as 16/14nm has 20nm metal layer and thus cannot scale as effectively.Refuge - Monday, June 1, 2015 - link
Distribution costs them more than manufacturing. lolChaser - Sunday, May 31, 2015 - link
That's pointless. 28nm with (Nvidia at least) is very energy efficient and as seen by this review a steal for the power this card delivers. It's a Titan X at $650.00. You're just desperately trying to find anything you can try and gripe about.Oxford Guy - Monday, June 1, 2015 - link
A GPU that expensive only qualifies as a steal if you're Leona Helmsley.mapesdhs - Tuesday, March 12, 2019 - link
2019 says hold my beer. :)Mark_gb - Monday, June 1, 2015 - link
Nvidia must make a living. No matter who they have to run over in the process. You, me, AMD... Doesn't matter. I imagine that at Nvidia, the mantra is "MUST MAKE MONEY! LOTS AND LOTS OF MONEY!", and that it repeats all day long, every day.P. T. Barnum was right... "There's a sucker born every minute."... and we are them.

What a shock that must be, for-profit corporation going about making profit. How dare they.mapesdhs - Wednesday, June 3, 2015 - link
Indeed, quite shocking. :)Personally I hope they make oodles of the stuff, so they can reinvest and make even better tech, because, my heavens, that's how private companies function. :D
It's weird how people complain about companies making profits, yet the very existence & continued success of a company depends on profits (unless of course one is AMD and somehow gets away with year after year of losses without going under).
(btw MB, please stop making crap Transformers movies... ;D Sorry, couldn't resist, hehe...)

Yeah ...but imagine how pissed you'd be if you'd brought a titan x in the last couple of months!I hope that extra 3% feels good!
