The NVIDIA GeForce GTX 980 Ti Review
by Ryan Smith on May 31, 2015 6:00 PM ESTSynthetics
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.

The performance difference between the 980ti and 980 is WAY larger than the performance difference between the 980 and 970 yet the price gap is larger between the 980 and 970. The 980 was stupidly overpriced at 550 and is still overpriced at 500. It needs to be at the 420-430 mark.I would be upset if I just paid 550 for a GTX 980 and now for only 100 more I could basically have titan x performance.

And what value do you place on the 9 months that 980 users have been enjoying that level of performance? Again, if you think the 970 is the better deal, it is there for you to buy at $300-330. The 980 was overpriced by maybe $50 at launch, but it still dropped the entire price and performance landscape at the time where 780Ti was still $650+, 290X was $550, 780 was $450 and 290 was $400. In that context, it wasn't so bad, was it?In reality, Nvidia has no reason to drop the 980 as there is no pressure at all from AMD. All these price cuts are self-induced as they are simply competing with themselves and pre-emptively firing a shot across the bow at $650 with 980Ti.

"In reality, Nvidia has no reason to drop the 980 as there is no pressure at all from a card with 3.5 GB of VRAM that, in part, runs at 28 GB/s and has XOR contention."fify

"In reality, Nvidia has no reason to drop pricing on the 980, as there is no point in threatening the golden calf that may have single-handedly killed AMD graphics, 3.5GB VRAM and all."FTFY ;)

I hope you're being paid for all this nonsense.Michael Bay - Tuesday, June 2, 2015 - link

Is it nonsense? I hope you are being paid for posting 3.5GB nonsense?darkfalz - Tuesday, June 2, 2015 - link
I dunno. I can't really justify an upgrade from my 980 STRIX (which would then replace beloved 680 in my HTPC) - I was hoping for at least 40% improvement. Not really worth it for 20-30%. Better off getting another 980 and SLI it.darkfalz - Tuesday, June 2, 2015 - link
I'm not sure why they aren't offering Witcher III as well as Batman. Why would a 970 get you two games? Not a great incentive to buy.SeanJ76 - Tuesday, June 2, 2015 - link
Yeah this card barely surpasses my 770 Sli, and I mean BARELY! I think I'll pass and wait for another die.
