RTX 2080 vs GTX 1080 Ti Comparison & Benchmarks

If you are considering of getting a high-end graphics card for 4K gaming then you can get stuck between GTX 1080 Ti and the newly launched RTX 2080. Both are very powerful graphics cards but are from different GPU series and have their own plus points and negatives. RTX 2080 is the second most powerful card in the RTX 20 series lineup while GTX 1080 Ti is the most powerful graphics card in the GTX 10 series.


RTX 2080, being a new card do come with some newer set of technologies and features that GTX 1080 Ti lacks, but GTX 1080 Ti does excel in other areas and has its own advantages over the RTX 2080. So, to clear out confusion between these cards, here I am going to compare both of them and tell you, which one is best for your gaming needs or requirements.

Here is a complete comparison between RTX 2080 and GTX 1080 Ti graphics cards based on their specifications, features, performance, power consumption and pricing. For reference purpose, I am comparing here Founders edition of both these graphics cards.

GPU Architecture

GeForce RTX 2080 is built on the Turing architecture which is the successor of Volta architecture and is one of the most powerful GPU architectures ever made. Turing GPU architecture supports both Ray Tracing and Artificial Intelligence that makes it more advanced than other GPU architectures. RTX 2080 comes with 2944 CUDA Cores and for Ray Tracing it has got RT Cores, and for AI & Deep learning it comes with Tensor Cores. The card is built on the 12nm fabrication process.

On the other hand, GTX 1080 Ti is built on the Pascal GPU architecture and comes with 3584 CUDA Cores which are way more than in RTX 2080. Pascal architecture does not support Ray Tracing and Artificial Intelligence which is its downside. GTX 1080 Ti is built on the 16nm manufacturing process which is the fabrication process for all the higher-end GTX 10 series graphics cards.

Video Memory (VRAM)

RTX 2080 comes with 8GB GDDR6 memory having 256-bit interface and clock speed of 14 Gbps. This offers memory bandwidth of 448 GB/s. On the other hand, GTX 1080 comes with 11GB GDDR5X memory having 352-bit interface and clock speed of 11 Gbps. It also offers memory bandwidth of 448 GB/s. This is because the wider memory interface of 352-bit makes up for the slower memory speed and results in the same memory bandwidth figure. However, GTX 1080 Ti clearly has an advantage here because it comes with 11GB memory which is 3GB more than present in RTX 2080. This may help in 4K gaming especially when using third party game mods, addons, or DLC packs that loads huge amount of textures in graphics card video memory.

Both these cards support features such as DirectX 12, OpenGL 4.5, Vulkan API, HDCP, Nvidia Ansel, GPU Boost, G-Sync to eliminate screen tearing, multi-GPU SLI support. However, RTX 2080 goes two steps further because it supports Real Time Ray Tracing for creating lifelike shadows and lighting in games, and Deep Learning Super-Sampling (DLSS) which is an AI powered Anti-aliasing technique and is offers far better performance compared to traditional Anti-aliasing techniques used by older GPUs and games. It must be noted that the game must support Ray Tracing and DLSS for GPU to take advantage of them. Also, you will find USB Type-C port on RTX 2080 for VirtalLink to connect virtual reality (VR) headsets directly.

Gaming Performance

Here are some benchmarks of RTX 2080 and GTX 1080 Ti graphics cards in some of the popular AAA games.


From the above gaming benchmarks, you can see that both these cards have similar kind of performance in all games at 4K. RTX 2080 is on average 6% faster than the GTX 1080 Ti which is very marginal improvement and is not worth considering. The real benefit of RTX 2080 lies in the Ray Tracing and DLSS which GTX 1080 Ti does not support. However, as of now we don’t see much of the games in future coming with Ray Tracing and DLSS and this narrows down the usefulness of RTX 2080. 

Power Consumption

When it comes to power consumption then there is very little to differentiate about because they both have almost similar figures. RTX 2080 consumes 225W of power while GTX 1080 Ti does a little more at 250W. However, the recommended power supply for RTX 2080 is a bit higher at 650W while for GTX 1080 Ti it is 600W. This is because RTX 2080 can reach higher boost clock compared to GTX 1080 Ti during auto-overclocking.

Price & Availability

Founders edition of RTX 2080 costs $799 MSRP while that of GTX 1080 Ti at $699 MSRP. Here, we can clearly see a price difference $100 and you can even find an aftermarket GTX 1080 Ti under $600. However, RTX 2080 has availability issues and most of the aftermarket variants of this card are well over 800 dollars. You can check the current prices of both these cards from different graphics card manufacturers by going to the links given below.

Final Thoughts & Conclusion

At the end I would like to say that both these cards are equally matched but RTX 2080 is a bit faster than GTX 1080 Ti in normal gaming where there is no Ray Tracing or DLSS. The price difference between these two cards is of 100 dollars at minimum, which may not sound that much but in GTX 1080 Ti you will get the same performance and extra 3GB RAM at lesser price. So, If you are looking for a powerful card for 4K gaming at reasonable price and don’t want all that fancy Ray Tracing and AI stuff then GTX 1080 Ti is still a very powerful card and you will not be disappointed at all. However, if you want the newer tech and want a taste of latest RTX 20 series card then you can go for RTX 2080 for a bit extra money.
