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.

He was highlighting incorrect grammar, not a typo. Btw, that should have been "it's", not "its", for the same reason. ;D My old English teacher would have used bullets for such errors if such as allowed...mapesdhs - Wednesday, June 3, 2015 - link
...and of course my own typo of 'as' instead of 'was' once again shows how annoying it is that in 2015 we still can't edit our posts on AT. :\FlushedBubblyJock - Wednesday, June 10, 2015 - link
thank you so much this is english class after allblastlike - Friday, June 26, 2015 - link
LOL you are so retarded. You try being a bitch and correcting others and at the end you fall into your own pit.Pathetic, lol keep it up.Gothmoth - Monday, June 1, 2015 - link
Toll, du beherrscht deine Mutterprache.. welch gewaltige Geistesleistung...... Amis.....Gothmoth - Monday, June 1, 2015 - link
2015 and on Anandtech we are still unable to edit comments.... here is the missing "s",freedom4556 - Friday, June 12, 2015 - link
...and you typo in yours? Or so Google translate suggests.shaolin95 - Friday, October 23, 2015 - link
Yes but the 980ti is still untouchable basically so 28nm or not...ComputerGuy2006...show me something better ;)Flunk - Sunday, May 31, 2015 - link
lower nm = more transistors in the same space = more performance, and possibly reductions in heat and power usage. There is only so much they can do on the 28nm node, which is why the next generation will likely utterly massacre the current one. 4K will be feasible at a reasonable price point.Refuge - Monday, June 1, 2015 - link
Depending on yields, lets not get too excited yet.I'll be excited when I get the email from Amazon saying my GTX1000TI is going to be here in two days and says I only spent $500 after rebate. :)
