Rust

The AMD Ryzen 7 5700 paired with the AMD Radeon RX 6800 XT delivers a robust, if uneven, experience in Rust. The data shows a system that can handle high refresh rate gaming at 1080p and solid 1440p performance, but which struggles to maintain smooth frame rates at 4K. The benchmark results reveal a clear performance hierarchy driven by both resolution and graphical presets, with the CPU and GPU alternating as the limiting factor depending on the workload.

Resolution Scaling

The measured FPS data shows a predictable decline as resolution increases, but the magnitude of that decline varies significantly by settings preset. At Low settings, the average frame rate drops from 193.3 FPS at 1920x1080 to 146.4 FPS at 2560x1440, a reduction of 46.9 FPS. Moving to 3840x2160 further reduces the average to 86.6 FPS, a substantial 55% drop from the 1080p figure. This scaling pattern indicates that at Low settings, the CPU is the primary bottleneck, as the GPU has ample headroom to render frames quickly, and the system is limited by the processor's ability to feed the game logic.

The scaling behavior changes dramatically at Ultra settings. Here, the average FPS falls from 92.3 at 1920x1080 to 60.5 at 2560x1440, and finally to 34.5 at 3840x2160. The 4K result represents a 62.6% reduction from the 1080p score. This steep decline suggests that at Ultra settings, the GPU becomes the dominant limiting factor, as the increased pixel count and graphical complexity saturate the Radeon RX 6800 XT's resources. The GPU's 16 GB of GDDR6 memory and 512.0 GB/s bandwidth are insufficient to maintain fluid performance at this resolution with maximum quality settings.

The Medium and High presets sit between these two extremes. At High settings, the frame rate scales from 115.5 FPS at 1080p to 81.8 FPS at 1440p, and then to 49.3 FPS at 4K. The Medium preset shows a similar trajectory, with 138.3 FPS at 1080p, 95.1 FPS at 1440p, and 56.4 FPS at 4K. Notably, the gap between Low and Ultra at 4K is 52.1 FPS, while at 1080p that gap is 101 FPS. This compression of performance at higher resolutions further confirms that the GPU is the primary constraint at 4K, while the CPU's capabilities are more fully utilized at lower resolutions where the GPU can render frames faster than the processor can maintain the game state.

The data indicates that for competitive play, the Low preset at 1080p is the optimal configuration, delivering 193.3 FPS. For a balanced visual experience, the High preset at 1440p offers 81.8 FPS, which remains playable for most users. The Ultra preset at 4K, with its 34.5 FPS average, is the least viable option, suggesting that users seeking 4K performance should reduce settings to Medium to achieve a more playable 56.4 FPS.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets. At 1920x1080, the system delivers an average of 193.3 FPS on Low settings, which is the highest score recorded in this dataset. The Medium preset reduces this to 138.3 FPS, while High settings yield 115.5 FPS. The Ultra preset brings the average down to 92.3 FPS, which is still above the 60 FPS threshold for smooth gameplay.

At 2560x1440, the performance scales down proportionally. The Low preset achieves 146.4 FPS, remaining highly playable for competitive scenarios. Medium settings produce 95.1 FPS, and High settings deliver 81.8 FPS. The Ultra preset drops to 60.5 FPS, which is exactly at the standard refresh rate for many monitors, making it a borderline choice for users who prioritize visual fidelity over frame rate consistency.

The 3840x2160 results show the most significant performance degradation. Low settings average 86.6 FPS, which is acceptable for most users. Medium settings drop to 56.4 FPS, and High settings fall to 49.3 FPS. The Ultra preset averages 34.5 FPS, which is below the threshold for smooth gameplay and would likely result in noticeable stuttering during intense action sequences. The data suggests that 4K gaming is only viable with this combo when using Low or Medium settings.

Across all resolutions, the delta between Low and Ultra settings is substantial. At 1080p, the difference is 101 FPS; at 1440p, it is 85.9 FPS; and at 4K, it is 52.1 FPS. This narrowing gap at higher resolutions reinforces the conclusion that the GPU becomes the limiting factor as pixel count increases, while the CPU's influence is more pronounced at lower resolutions.

GPU Role

The AMD Radeon RX 6800 XT plays a critical role in determining the system's performance ceiling in Rust. The GPU features 16 GB of GDDR6 memory on a 256-bit bus, providing a bandwidth of 512.0 GB/s. This memory configuration is sufficient for the game's textures and assets at 1080p and 1440p, as evidenced by the strong frame rates at those resolutions. However, at 4K Ultra settings, the 16 GB capacity and bandwidth appear to be a limiting factor, as the average frame rate falls to 34.5 FPS.

The GPU's clock speeds are specified as a base of 1825 MHz, a game clock of 2015 MHz, and a boost clock of 2250 MHz. These clocks allow the card to maintain high throughput in compute-heavy scenes, which is reflected in its 20.74 TFLOPS of FP32 performance. The 4608 shading units and 288 texture mapping units provide ample parallel processing power for the game's rendering pipeline. The 128 ROPs handle pixel output, which becomes increasingly important at higher resolutions.

The GPU's 72 ray tracing cores are present but are not directly relevant to Rust's standard rendering path, which primarily relies on rasterization. The card's DirectX 12 Ultimate support ensures compatibility with the game's modern API features, while its Vulkan 1.4 support allows for efficient multi-threaded rendering. The PCIe 4.0 x16 interface provides sufficient bandwidth for data transfer between the CPU and GPU, minimizing potential bottlenecks.

The GPU's role as the limiting factor at 4K is clear from the performance scaling. The 62.6% reduction in frame rate from 1080p Ultra to 4K Ultra indicates that the card is unable to maintain its performance as pixel count increases. This is typical for a GPU in the RX 6800 XT's class, which is positioned as a high-end card for 1440p gaming but requires reduced settings for comfortable 4K play. The GPU's 300 W TDP and dual-slot design suggest it is a power-hungry component, and its suggested 700 W power supply requirement should be considered when building a system around this combo.
