Welcome to the Nvidia RTX 3090 vs RTX 2080 Ti benchmark comparison. In this review, we will take a deep look at how these two graphics cards compare to one another, as well as how these hardware specs deliver in gaming performance.
The 3000 series Ampere graphics cards are the first RTX and Raytracing generation to follow the initial Turning graphic cards, launched in 2018. Nvidia’s Turning cards have open the doors for developers to finally implement real time Raytracing into their games, and the results are spectacular.
I have a full list of the Best Raytracing Games available here, for you to check out. Not only that, the RTX platform also introduced DLSS, which has had mind blowing results in my benchmarks of the Best DLSS Games, doubling the performance of many of the gaming titles in 4K.
Ampere is set to take the foundation of what Turning started to the next level of performance and visual experience.
With that said, let’s see how the Nvidia RTX 3090 compares to the RTX 2080 Ti.

Nvidia RTX 3090 vs RTX 2080 Ti - Benchmarks
With all the above tech specs said and done, let’s dive right into the RTX 3090 vs RTX 2080 Ti Benchmarks and see how they relate to real world gaming performance.
Below are 29 current gen games benchmarked at 2.5K (2560×1440) & 4K (3840×2160) resolutions.
All games benchmarks were done while using Nvidia GeForce Experience (Shadowplay) recording software. This was done as I wanted to create a worst case scenario for the benchmarks that YouTube Gamers would experience, as this recording software generally has about about a 5% hit in performance.
FYI: This is a far lower performance hit than in OBS, which is the reason I don’t use it for my YouTube 4K gameplay recordings.
If you don’t use recording software, then you can simply add back about 5% to all the below results.
