Nvidia's RTX 2080 is 35% to 125% faster than the GTX 1080 in 4K games thanks to DLSS
Even though Nvidia imposed an RTX 2000-series review embargo that will end on September 14, select publications were able to shortly assess the new cards on spot at GamesCom. Nvidia only showed side-by-side comparison between current gen and Turing cards and did not really disclose all the settings. Moreover, the green team stated that the performance numbers could be improved by the official launch scheduled for September 20, so the graphs they showed may provide the expected performance gains, but not definitive numbers.
The graph revealed by Nvidia compares how much better the RTX 2080 performs versus the GTX 1080. It seems as though the company hand-picked 10 games running in 4K, and six of these support the Deep Learning Super-Sampling technology that should boost the fps count even more. It should be noted here that developers need to release new patches for their games in order to add support for the DLSS tech, so not all existing games on the market may benefit from it.
DLSS is an improved form of the anti-aliasing technique that makes use of the Turing Tesnor cores as a neural network that improves the image quality through 64 jittered samples of a very high-quality ground truth image. Now, in order to increase the overall performance, the games supporting this new technology need to have anti-aliasing turned off and DLSS activated instead. On-site testers claim that DLSS provides similar result to AA as far as image quality is concerned, and the performance boost is quite significant. The increase in performance without DLSS is anywhere between 35-50%, while the activation of DLSS may add up to 60% more fps.
The games that do not support DLSS still benefited from 40-60% increased fps counts. Additionally, a second slide with the actual fps count for each game running in 4K emphasizes the fact that all games are running at more than 60 fps in 4K, but the actual settings used for the tests are not publicly available at this time.
While 4K is indeed more taxing on the performance, gamers may also want to see how much faster the new cards are in 1080p. The GTX 1080 was already overkill for most current titles in 1080p, so the average gamer may not need to look beyond that, now that the prices for the GTX 1000-series are falling well below MSRP.
