AMD RX 6900 XT 1440p/4K gaming specs, price, and comparisons.

The AMD Radeon RX 6900 XT boosted high-end graphics card sales. AMD's flagship can compete with NVIDIA's top GPUs, especially the GeForce RTX 3090, with its architectural improvements and 4K gaming performance.

Architecture of RDNA2

AMD's RDNA 2 Architecture revolutionised. AMD's graphics cards got real-time ray tracing and better performance per watt than RDNA 1. AMD's bandwidth-caching Infinity Cache debuted this generation. To reduce delay and increase memory bandwidth, AMD chose a fast 128MB cache over a power- and cost-intensive memory bus.

Smart Access Memory (SAM) is another major improvement. With a Ryzen processor and 500 series motherboard, SAM gives the CPU full access to the GPU's memory, improving game performance by 10% to 15%.

Gaming: 4K/1440p Champion

The RX 6900 XT still excels in many games in 2024. In most modern 1440p games, it easily hits triple-digit frame rates on maximum settings. At 4K, the card runs nicely, averaging 60–90 FPS, depending on the game.

Examine some popular titles' averages:

Cyberpunk 2077: ~87 FPS (1440p Ultra, no ray tracing)

Modern Warfare II (4K Ultra): ~85 FPS

FPS ~70 in Assassin's Creed Valhalla (4K Ultra).

FPS ~100 in Red Dead Redemption 2 (1440p Ultra).

Forza Horizon 5 (4K Extreme): ~92 FPS

In standard rasterisation tasks, the RX 6900 XT often outperforms the RTX 3080 and occasionally approaches the 3090. AMD lags in ray tracing. The RX 6900 XT can handle ray tracing when used sparingly, but to maintain frame rates at 4K, it must be enabled at the sacrifice of other settings or AMD's FidelityFX Super Resolution.

FidelityFX Ray Tracing and Super Resolution

DLSS vs. AMD FidelityFX Super Resolution. The visual quality and performance of FSR 2.0 and 3.0 were better than 1.0. FSR is more versatile because it supports older Radeon and NVIDIA GPUs.

RX 6900 XT ray tracing is bad. Despite real-time ray tracing, the card performs badly compared to NVIDIA's RTX series. Ray tracing slows Control and Cyberpunk 2077 compared to RTX 3080 or 4080.

Cooling and power efficiency

At 300W TBP, the RX 6900 XT uses more power than mid-range GPUs yet produces great performance. Most custom Sapphire, ASUS, and PowerColor designs feature triple-fan cooling systems with massive heatsinks. These cards run quietly and stay below 75°C even under severe loads compared to other high-end GPUs.

Despite being warmer and noisier under stress, the AMD standard architecture performs well. A durable, straightforward design and triple-fan axial configuration make it look well in any project.

Feature Software

Adrenalin Software Suite from AMD is a good GPU control panel. Performance monitoring, gaming profiles, overclocking, and streaming are included. Radeon Boost, Chill, and Anti-Lag control input latency and performance. Integrated game capture and streaming software ReLive is an AMD advantage. OBS is unnecessary unless you need further customisation.

Buy the RX 6900 XT Who?

Gamers that want top-tier 1440p and 4K performance without buying newer models

Ryzen CPU users have Smart Access Memory.

Budget builders seeking secondary sector premium power

Those that want a high raw frame rate without ray tracing

AMD RX 6900 XT benchmark

AMD Radeon RX 6900 XT synthetic and gameplay benchmarks. Average test results from many sources determine the 1080p, 1440p, and 4K benchmarks.

The RX 6900 XT's 1080p frame rates are often too high for 60Hz screens.

RX 6900 XT's 1440p sweet spot enables it run all recent games at high settings with acceptable frame rates.

Ray Tracing is slower than RTX 3080/3090. To improve performance, use FSR 2.0 or 2.1.

AMD RX 6900 XT costs

A premium graphics card, the $999 AMD Radeon RX 6900 XT. As a card from a previous generation, its price may vary depending on whether you buy a new or used one.

In summary

The AMD Radeon RX 6900 XT is still a powerful graphics card after several years. It has flagship gaming performance, lots of VRAM, and low power consumption at a reduced price. RX 6900 XT is a good alternative for budget gaming PCs or 10 or 20-series card upgrades.
