The RX 6900 XT is an enthusiast-grade powerhouse. It features the fully unlocked “Navi 21” chip, meaning it has the maximum number of cores available for this generation. While it shares the same 16GB of VRAM as the 6800 XT, it is binned for higher quality and better performance, making it the definitive choice for 4K Ultra gaming and professional creative workloads.
Main Features
Fully Unlocked RDNA 2 Architecture: Features 80 Compute Units (5120 Stream Processors)—the highest count possible for the 6000 series.
16GB GDDR6 Memory: A massive memory buffer that handles 4K textures and heavy video editing without breaking a sweat.
128MB Infinity Cache: This massive cache allows the card to punch way above its weight class at 4K by providing ultra-fast access to game data.
80 Ray Accelerators: Hardware-level ray tracing support for realistic shadows, reflections, and global illumination.
FSR 3 & Frame Generation: Fully compatible with AMD’s latest software, allowing you to play the most demanding modern games at high frame rates even at 4K.
Smart Access Memory (SAM): When paired with a Ryzen 5000+ CPU, the system unlocks additional performance by giving the processor full access to the VRAM.
Premium “Binning”: RX 6900 XT chips are often higher quality than 6800 chips, meaning they can often be overclocked higher or undervolted more effectively for better efficiency.
Modern Media Engine: Supports AV1 decoding, 8K video streaming, and 4K encoding for high-quality recording.
