RTX-2080Ti

Always since Nvidia announced the RTX 2080 and RTX 2080 Ti, information technology'south been an open question just how much performance comeback these GPUs would offer in current games. The word has been driven in part by the significant price increases Nvidia has slapped on these latest cards and by the company'due south refusal to disclose much in the mode of operation information on its new GPU family. Nvidia did show new data at GTC Nippon this week, however — and confirmed in the process that it won't be offering much of a price/performance comeback over and above its previous cards without specialized features being enabled in-game.

Nvidia showed two new slides at this event — one with DLSS enabled, and one without. Here they both are.

At kickoff glance, this seems to restate and agree with Nvidia'due south previously disclosed information, which suggested DLSS (which uses AI to perform supersampled antialiasing) would indeed offering a large performance improvement to the RTX 2080 and RTX 2080 TiSEEAMAZON_ET_135 See Amazon ET commerce. As far as the RTX 2080 and 2080 Ti are concerned, that's accurate. But if you bank check — and we did — the relative performance of Maxwell and Pascal don't modify at all between these two graphs. And that doesn't make whatever sense.

One of the reasons we have so many different types of antialiasing (MSAA, SSAA, MLAA, FXAA, to name a few), broadly speaking, is because we've spent decades developing different methods of improving epitome quality without sacrificing too much functioning. Solutions similar FXAA, which applies a post-processing filter to simulate anti-aliasing rather than performing it in the traditional way, often better prototype quality with virtually no functioning hitting at all. Supersampling or upscaling, on the other hand, is 1 of the best ways to improve image quality merely the traditional performance striking from this method has been enormous. The minimum operation impact from enabling AA is 0 percent.

One style for the 9xx and 10xx families to maintain identical frame rates in both graphs is if none of the GPUs in question have any type of AA enabled in Graph #1 — but if this is true, it would hateful that the RTX 2080 and 2080 Ti are actually faster with DLSS enabled than with information technology disabled. Based on what's been publicly disclosed about the DLSS characteristic, this seems impossible. DLSS is a specific event that uses car learning to reduce noise and jaggies in an paradigm. Information technology does not accelerate the entire rendering pipeline or otherwise improve baseline functioning.

Alternatively, we can assume that some level of AA is being applied to all of the cards in question in the commencement graph, and that the second graph shows what happens when the RTX 2080/2080 Ti switch to DLSS while the older cards stick with their original AA method. This explains why the RTX family unit's operation jumps in the last graph while the older cards don't. Only this caption gets stuck in another place — the relative position of the GTX 1080 Ti and 1080SEEAMAZON_ET_135 See Amazon ET commerce to that 4K 60fps gaming bar stretching across the screen.

We don't know the detail settings Nvidia used for these comparisons or fifty-fifty the game titles, just we can however go a feel for the numbers by checking how the GTX 1080 Ti stacks upwardly in 4K testing beyond multiple reviews. We checked data from Anandtech, Tech Report, and [H]ardOCP's contempo GeForce generational comparisons to make that determination. Nearly publications, including this one, declared the GeForce GTX 1080 Ti to be a "true" 4K gaming GPU thank you to its excellent overall functioning. Anandtech's review shows the GeForce GTX 1080 Ti breaking the 60fps barrier at 4K in 6 out of 9 titles. Tech Report had the GTX 1080 Ti over the 60fps hump in 4 out of ten games, while [H]ardOCP, which performed the largest comparison and the nigh recent round of testing, had the 1080 Ti breaking 60fps in 12 out of fifteen games. Beyond all three reviews, that comes out to 22 tests in which the 1080 Ti was over 60fps and 12 where it was not. Of the 12 games where information technology didn't break 60fps, the 1080 Ti is ofttimes in the 54-57fps range.

The area under Nvidia's 4K/60fps line is 131 pixels tall. The top of the 1080 Ti'south green bar is 15 pixels below this line. Do the math, and the graph suggests that the 1080 Ti hits about 53fps in 4K on boilerplate. That's well below the combined average of our three reviews, but Nvidia may simply have chosen games where Pascal didn't perform particularly well. If you lot zero in on the games where the 1080 Ti falls short of the 4K mark, that 53fps average is pretty much spot on.

But therein lies the rub: Most reviewers don't test 4K with high levels of AA enabled and many of the benchmark results in the reviews we linked don't apply it at all (or but apply FXAA/SMAA) for that resolution. ExtremeTech is actually a piddling odd in that nosotros do test with heavy AA, even in 4K — and when nosotros do, those results are quite a scrap lower, as shown in our own slideshow from the 1080 Ti launch.

If you're having trouble keeping all of this direct, permit us to summarize. The 1080 Ti'south performance scores imply that very trivial AA is in-employ at 4K, while the RTX family unit's performance jump from Graph #one to Graph #2 implies that a heavy AA solution has just been disabled and replaced by a much more than efficient one. With a heavy AA solution engaged, the 1080 Ti'due south average level of operation should be much lower (check our own review results above in Rise of the Tomb Raider and Metro Last Low-cal Redux for examples of how much operation you lose when enabling SSAA).

One more thing. Nvidia'southward 4K@60 line is 131 pixels tall, which ways each pixel is "worth" approximately 0.46fps. The height gap between the RTX 2080 and the GTX 1080 Ti, measured acme-left corner to top-left corner, is 20 pixels. If we assume that Nvidia'southward graph is accurate, this implies the RTX 2080 will outperform the GTX 1080 Ti by ~9 percent at the aforementioned cost (if $700 cards are fifty-fifty in stock for launch). And this, in turn, may explicate why Nvidia is putting so much emphasis on DLSS and ray tracing in the first identify — because introducing a 9 percentage operation improvement at the aforementioned price isn't anything that's going to become anyone excited.

These Graphs Don't Tell United states of america Anything Useful

Ever since Nvidia announced the RTX 2080, I've encouraged readers to wait for the cards to launch and to carefully consider the likely adoption trajectory of whatever new GPU features earlier shucking out huge amounts of coin. Subsequently analyzing these graphs, that'south still our advice.

Why? Because we shouldn't take to play detective to figure out what a company is actually trying to say with its product marketing. Nosotros already know that even the RTX 2080 Ti struggles to maintain 60fps in 1080p with ray tracing enabled in some games. Nvidia'due south graphs purporting to show DLSS improvements are nonsensical every bit written. The data they evidence strongly implies that an uneven comparing is being made between AA modes. I'd dearest nothing more than to come across a high-quality, loftier-performance anti-aliasing method come up to market; I've loved supersampled antialiasing since the days of the Voodoo 5 5500. Only the data in Nvidia'southward graphs points in two directions at in one case. Something as simple as a global "8x MSAA compared with DLSS" would solve this problem, but Nvidia didn't provide that data.

Nvidia may indeed deliver a Turing that blows everyone'south socks off and offers huge performance improvements, but the slides the company is distributing to make that argument don't make information technology. How meaning is that? I genuinely don't know. What I do know is that companies e'er try to put their all-time pes frontwards in every case, and Nvidia is full of consummate professionals who know how to make those cases. The data available on Turing points to a visitor trying to put a lot of shine on a product past highly-seasoned to what information technology can do in the futurity every bit opposed to what it can offer you now.

The bug with these graphs crave u.s.a. to read them conservatively. The bourgeois read is that the RTX 2080 will be ~9 percentage faster than the GTX 1080 Ti. The GTX 1080 Ti volition remain the appropriate indicate of comparison for the RTX 2080 based on their respective price bands.
