The AMD Radeon RX 6900 XT is here, and it only costs $999… if you can find one!
Here is what you need to know about the ultimate Big Navi graphics card!
AMD Radeon RX 6900 XT : Official Tech Briefing + Q&A Session
AMD claims that the Radeon RX 6900 XT is the ultimate 4K graphics card, thanks to its new RDNA 2 architecture with 80 enhanced Compute Units and 16 GB GDDR6 memory.
Let’s start with the official tech briefing and Q&A session with Nish Neelalojanan, Senior Manager of Gaming Product Management at the AMD Radeon Technologies Group.
AMD Radeon RX 6900 XT : Key Features
The AMD Radeon RX 6000 series graphics cards are built on the new RDNA 2 architecture, which features an enhanced Compute Unit, a new visual pipeline with Ray Accelerators, and the new AMD Infinity Cache.

AMD Smart Access Memory
This is an exclusive feature that is enabled when a Radeon RX 6000 series graphics card is paired with the Ryzen 5000 series processor and an X570 motherboard.
The Ryzen 5000 processor is given greater access to its GDDR6 graphics memory, providing up to 13% better performance when combined with the new Rage Mode one-click overclocking setting.

AMD Infinity Cache
The AMD Infinity Cache is a new and very large 128 MB data cache. Think of it as an L3 cache for the GPU.
AMD added it to dramatically increase memory bandwidth, which reducing memory latency and power consumption.
They claim it delivers up to 3.25X the bandwidth of the 256-bit GDDR6 memory, and up to 2.4X more effective bandwidth per watt.

DirectX 12 Ultimate Support
They will support the next-generation games with greater realism through DirectX Raytracing (DXR) and Variable Rate Shading.
New Ray Accelerator
Every RDNA 2 computer unit has a new fixed-function Ray Accelerator engine to deliver real-time lighting, shadow and refection realism through DirectX Raytracing (DXR).
It can be paired with AMD FidelityFX to enable hybrid rendering, offering a combination of rasterised and ray-traced effects for a blend of better image quality and higher performance.
Variable Rate Shading (VRS)
Variable Rate Shading dynamically reduces the shading rate for areas of the frame that do not require a high level of visual quality, improving performance at little to no perceptible loss in image quality.
Microsoft DirectStorage Support
They will support the future DirectStorage API for faster load times, and high-quality textures.
