Radeon RX 5700 XT vs GeForce GTX 1080 Ti: Full Comparison
Quick Answer
The Radeon RX 5700 XT and GeForce GTX 1080 Ti are graphics cards from different generations that often compete in a similar performance tier. The GTX 1080 Ti, a previous-generation flagship, typically holds a slight edge in raw performance and memory capacity. The RX 5700 XT, built on a newer architecture, introduced features like PCIe 4.0 support and is generally more power-efficient.
Introduction
Comparing the Radeon RX 5700 XT and the GeForce GTX 1080 Ti is an interesting exercise in evaluating generational shifts in graphics technology. The GTX 1080 Ti was a dominant high-end card, while the RX 5700 XT arrived later as a competitive offering in the upper-midrange segment. This comparison will break down their architectures, gaming performance, feature sets, and efficiency to help clarify where each model stands.
Architecture and Specifications
The fundamental designs of these two GPUs are quite different, stemming from their respective generations.
- Radeon RX 5700 XT: Based on AMD’s RDNA 1 architecture and manufactured on a 7nm process. It features 40 Compute Units, 2560 stream processors, and 8GB of GDDR6 memory on a 256-bit bus.
- GeForce GTX 1080 Ti: Built on NVIDIA’s Pascal architecture using a 16nm process. It utilizes a larger GPU with 3584 CUDA cores and a significant 11GB of GDDR5X memory on a 352-bit bus.
The newer 7nm process of the RX 5700 XT contributes to its efficiency, while the GTX 1080 Ti’s larger memory buffer and wider bus were hallmarks of its flagship status.
Gaming Performance
In real-world gaming, the performance difference can vary based on resolution, game title, and driver optimizations.
- 1080p and 1440p Gaming: At these resolutions, the two cards are often closely matched. The GTX 1080 Ti typically maintains a small lead in many titles, but the margin can be narrow, sometimes within a few percentage points.
- 4K Gaming: The GTX 1080 Ti’s advantage can become more apparent at 4K resolution. Its larger 11GB VRAM and wider memory bus are beneficial for handling the high-resolution textures and data, leading to more consistent performance in demanding scenarios.
- Game-Specific Performance: Titles that are optimized for or leverage newer graphics APIs (like DirectX 12 Ultimate features) may show better performance on the RX 5700 XT, while older or traditionally NVIDIA-favored games might favor the GTX 1080 Ti.
Features and Technologies
The feature sets reflect the technological context of their respective launch periods.
- Radeon RX 5700 XT: Introduced support for PCI Express 4.0, which doubles the bandwidth compared to PCIe 3.0. It also supports hardware-accelerated ray tracing, though performance for this feature is limited on the first-generation RDNA architecture.
- GeForce GTX 1080 Ti: Lacks dedicated hardware for ray tracing and DLSS, which were introduced in the subsequent Turing generation. Its feature set is focused on the high-performance rasterization gaming of its time.
Both cards support standard features like variable refresh rate technologies (FreeSync and G-Sync Compatible, respectively).
Power and Thermals
Power consumption and thermal output are practical considerations for system builders.
- Power Draw: The Radeon RX 5700 XT has a typical board power (TBP) of 225 watts. The GeForce GTX 1080 Ti has a TDP of 250 watts. In practice, the RX 5700 XT is generally more power-efficient on a performance-per-watt basis due to its newer architecture and manufacturing process.
- Thermals and Cooling: Thermal performance is heavily dependent on the specific cooler design from each board partner (AIB). Both cards can run warm under load with reference-style coolers, but aftermarket models from various manufacturers typically offer improved thermal and acoustic performance.

Frequently Asked Questions
Which is generally faster, the RX 5700 XT or GTX 1080 Ti?
The GeForce GTX 1080 Ti typically offers slightly higher average frame rates, particularly at 4K resolution, due to its larger memory capacity and wider bus. However, the performance gap at 1080p and 1440p is often quite small.
Does the RX 5700 XT have any feature advantages?
Yes. The RX 5700 XT supports the PCIe 4.0 interface and includes first-generation hardware acceleration for ray tracing, features not present on the GTX 1080 Ti. It is also built on a more modern and power-efficient 7nm process.
Is the GTX 1080 Ti’s 11GB VRAM a significant advantage?
It can be, especially for gaming at 4K resolution or when using very high-resolution texture packs in modern games. The extra VRAM helps prevent performance dips in scenarios that require more graphical memory.
Which card is more power-efficient?
The Radeon RX 5700 XT is generally more power-efficient, delivering comparable performance at a lower typical board power, thanks to its newer 7nm RDNA architecture.
Final Thoughts
The Radeon RX 5700 XT and GeForce GTX 1080 Ti represent strong options from their respective eras. The GTX 1080 Ti maintains an edge in raw performance and high-resolution capability, a testament to its flagship origins. The RX 5700 XT counters with a more modern architecture, better efficiency, and support for newer platform features like PCIe 4.0. The choice between them often depends on the specific resolution and games being played, as well as the value placed on newer features versus outright performance in traditional rendering.
