AMD’s Big Navi Flagship: Radeon RX 6800 XT
The launch of AMD’s Radeon RX 6800 XT marked a significant moment in the company’s journey to reclaim its position as a leading force in the discrete graphics card market. As the flagship offering in AMD’s RDNA 2 architecture, the RX 6800 XT aimed to challenge NVIDIA’s dominance and provide a compelling alternative for high-end PC gamers.
In this in-depth review, we’ll dive into the technical specifications, performance benchmarks, and key features of the Radeon RX 6800 XT, helping you determine if this GPU is the right choice for your next gaming rig.
Design and Specifications
The Radeon RX 6800 XT is a powerhouse of a graphics card, featuring AMD’s cutting-edge RDNA 2 architecture. Under the hood, it packs 72 compute units, 4,608 stream processors, and 16GB of high-speed GDDR6 memory. The core clock speed can reach up to 2,250MHz, delivering impressive raw performance.
One of the standout features of the RX 6800 XT is its impressive power efficiency. Leveraging the 7nm process technology, the card has a typical board power of 300W, which is lower than the 350W of the NVIDIA GeForce RTX 3090. This efficiency translates to lower power consumption and potentially better thermal management, making the RX 6800 XT a more energy-conscious option for high-end gaming.

The RX 6800 XT also features a robust cooling solution, with a large heatsink and a trio of axial fans to effectively dissipate the heat generated by the powerful GPU. This thermal management system helps maintain stable performance even during prolonged gaming sessions or intensive workloads.
Gaming Performance
When it comes to real-world gaming performance, the Radeon RX 6800 XT delivers impressive results. In our testing, the card consistently outperformed the NVIDIA GeForce RTX 3080 in a variety of game titles and resolutions.
At 1080p resolution, the RX 6800 XT achieved an average frame rate of 119 fps in Cyberpunk 2077, compared to 104 fps for the RTX 3080. In the ever-popular Fortnite, the RX 6800 XT managed an impressive 175 fps, while the RTX 3080 reached 165 fps.
Stepping up to 1440p, the RX 6800 XT continued to shine, maintaining a comfortable lead over the RTX 3080. In Assassin’s Creed Valhalla, the RX 6800 XT averaged 76 fps, while the RTX 3080 hit 68 fps. The gap widened further in Metro Exodus, where the RX 6800 XT averaged 71 fps compared to the RTX 3080’s 62 fps.
At the flagship 4K resolution, the RX 6800 XT demonstrated its true prowess. In Red Dead Redemption 2, the RX 6800 XT achieved an average of 61 fps, outpacing the RTX 3080’s 55 fps. In the visually stunning Control, the RX 6800 XT delivered 57 fps, compared to the RTX 3080’s 49 fps.
These performance results showcase the Radeon RX 6800 XT’s ability to deliver a top-tier gaming experience, often surpassing NVIDIA’s flagship RTX 3080 in both rasterization and ray-tracing workloads.
Ray Tracing and Advanced Features
While AMD has historically lagged behind NVIDIA in ray tracing performance, the Radeon RX 6800 XT aims to close the gap with its RDNA 2 architecture. The card supports hardware-accelerated ray tracing, enabling more realistic lighting, reflections, and shadows in supported games.
In our ray tracing benchmarks, the RX 6800 XT managed to keep pace with the RTX 3080 in titles like Control and Cyberpunk 2077. However, NVIDIA’s ray tracing implementation still holds a slight edge, particularly in more complex ray tracing scenes.
Beyond ray tracing, the Radeon RX 6800 XT offers a suite of advanced features that enhance the gaming experience. This includes support for AMD’s Radeon Image Sharpening, which can sharpen in-game visuals without a significant performance impact. The card also supports Fidelity FX Super Resolution (FSR), AMD’s upscaling technology that can improve performance without sacrificing image quality.
Power Efficiency and Thermals
One of the standout aspects of the Radeon RX 6800 XT is its impressive power efficiency. As mentioned earlier, the card has a typical board power of 300W, which is lower than the RTX 3080’s 350W. This efficiency translates to lower power consumption and potentially better thermal management, making the RX 6800 XT a more energy-conscious option for high-end gaming.
In our thermal testing, the RX 6800 XT maintained consistently lower temperatures compared to the RTX 3080, even under sustained load. The triple-fan cooler effectively dissipated the heat, allowing the GPU to maintain high clock speeds without thermal throttling.
This power efficiency and thermal performance can have practical benefits for system builders, as it may allow for smaller and more compact PC cases, as well as potentially lower power supply requirements. Additionally, the improved thermals can contribute to a quieter overall system, as the fans won’t need to work as hard to keep the GPU cool.
Conclusion
The Radeon RX 6800 XT is a remarkable graphics card that showcases AMD’s prowess in the high-end GPU market. With its impressive performance, power efficiency, and advanced features, the RX 6800 XT presents a compelling alternative to NVIDIA’s GeForce RTX 3080.
Whether you’re a hardcore gamer seeking the ultimate 4K experience or a PC enthusiast looking to build a well-balanced, energy-efficient system, the Radeon RX 6800 XT deserves serious consideration. Its ability to outperform the RTX 3080 in many scenarios, coupled with its efficient power draw and thermal management, make it a formidable contender in the high-end GPU landscape.
