Radeon RX 6900 XT 16GB Game Requirement Analysis
Overview
The Radeon RX 6900 XT 16GB is an Enthusiast gaming Graphics Card based on the second (2.0) Revision of the RDNA Architecture.
Architecture
The Navi 21 GPU offers support for GDDR6 Memory, DirectX 12 Ultimate, Vulkan 1.2, and OpenGL 4.6.
This variant of the Navi 21 GPU features 80 Compute Units activated, offering 5120 Shader Processing Units, 320 TMUs and 128 ROPs. The GPU features a 1825 MHz base clock speed and up to 2250 MHz with boost clock. This puts its predicted performance roughly in line with the GeForce RTX 3090.
GPU
The Central Unit is clocked at 1825 MHz, rising to 2250 MHz with boost clock enabled.
Memory: Speed
The GPU is equipped with high-speed GDDR6 and accesses the Frame Buffer through a 256-bit memory interface, providing total memory bandwidth of 512 GB/s.
Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 16GB. Under most circumstances, this only proves useful in certain 3D Games whose Settings Require Large Amounts of Memory.
However, the GPU itself is aimed for 4K Gaming, In some limited scenarios, 16GB might be a bottleneck and Performance could be better were the Frame Buffer larger, however this would only be an issue in the most demanding games.
Power Consumption
With a rated board TDP of 300W, it requires at least a 850W PSU with two available 8-pin connectors.
Performance
AMD Radeon RX 6900 XT 16GB competes with GeForce RTX 3090 24GB, which is available for $1499.
Specs currently available suggest the AMD Radeon RX 6900 XT 16GB performance should be in the same region as the GeForce RTX 3090.
System Suggestions
AMD Radeon RX 6900 XT 16GB is best suited for resolutions up to and including 3840 x2160 (4K). For the most demanding AAA games it should be ideally suited to 4K. We recommend a Very Strong Processor and at least 16GB of RAM for Optimal Performance.
