The flagship Navi based graphics cards have been highly anticipated ever since AMD introduced its first-generation RDNA lineup. While the first generation RDNA gave us a small glimpse of what we could expect from a flagship offering, the lineup never really introduced its own flagship variant & instead focused on the more mainstream performance-ended products. But two years later, the wait is finally over!

AMD has officially launched its Big Navi graphics card lineup and it's not just the biggest Navi GPU we have seen to date but also based on the 2nd Generation RDNA 2 architecture which delivers an impressive leap in performance per watt while offering a range of new features to put AMD Radeon ack in the high-end and enthusiast market segment.

The AMD RDNA 2 architecture for its Big Navi Radeon RX 6800 and RX 6900 series graphics cards has a lot to offer. In addition to architectural enhancements, you can expect hardware-accelerated ray tracing, smart access memory, Infinity Cache, and a lot more features on-deck which make the lineup one of the most competitive enthusiast families that AMD has ever positioned against NVIDIA.

Some of the main features for the AMD Radeon RX 6000 series graphics cards include:

AMDInfinity Cache–A high-performance, last-level data cache suitable for 4K and 1440p gaming with the highest level of detail enabled. 128 MB of on-die cache dramatically reduces latency and power consumption, delivering higher overall gaming performance than traditional architectural designs.AMDSmartAccessMemory – An exclusive feature of systems with AMD Ryzen 5000 Series processors, AMD B550 and X570 motherboards, and Radeon RX 6000 Series graphics cards. It gives AMD Ryzen processors greater access to the high-speed GDDR6 graphics memory, accelerating CPU processing and providing up to a 13-percent performance increase on an AMD Radeon RX 6800 XT graphics card in Forza Horizon 4 at 4K when combined with the new Rage Mode one-click overclocking setting.Built for Standard Chassis– With a length of 267mm and 2x8 standard 8-pin power connectors, and designed to operate with existing enthusiast-class 650W-750W power supplies, gamers can easily upgrade their existing large to small form factor PCs without additional cost.

Today, we will be taking a look at the Radeon RX 6800 XT & RX 6800 reference models. These cards were provided by AMD for the sole purpose of this review & we will be taking a look at their tech, design, and performance metrics in detail.
