Rust

The AMD Ryzen 7 9700X paired with the AMD Radeon RX 6800 XT delivers a performance profile in Rust that is heavily dictated by resolution and graphical presets. The measured data shows a clear scaling pattern from 1080p to 4K, with the GPU becoming an increasingly dominant factor as pixel count rises. This analysis breaks down the measured FPS rows, contextualizes the hardware roles, and provides actionable settings guidance based strictly on the provided facts.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial and reveals where the bottleneck shifts. At 1920x1080 with Low settings, the combo produces 209 FPS, but at 3840x2160 with Low settings, that figure falls to 85 FPS — a reduction of 124 FPS. This 59.3% drop at the same settings indicates that even at Low preset, the GPU is being pushed hard by the 4K pixel count. Similarly, at High settings, the average FPS falls from 119 at 1080p to 82 at 1440p and then to 48 at 4K. The step from 1080p to 1440p costs 37 FPS, while the step from 1440p to 4K costs another 34 FPS, showing a consistent linear degradation as resolution increases.

The scaling pattern suggests that at 1080p, the CPU still has headroom to push higher frame rates, but the GPU begins to limit as resolution climbs. At 4K with Ultra settings, the combo only manages 37 FPS, which is below the 48 FPS seen at High settings — a 11 FPS penalty for the Ultra preset. This indicates that the RX 6800 XT's 16 GB of VRAM and 512.0 GB/s bandwidth are sufficient for the data load, but the raw compute throughput (20.74 TFLOPS FP32) becomes the limiting factor at 4K.

The Medium preset shows the most balanced scaling across resolutions. At 1080p, it hits 140 FPS, at 1440p it drops to 97 FPS, and at 4K it reaches 57 FPS. The percentage drop from 1080p to 1440p is 30.7%, and from 1440p to 4K is 41.2%. This suggests that the Medium preset is where the CPU-GPU balance is most even, as the GPU still has enough resources to handle the increased pixel count without collapsing entirely.

GPU Role

The AMD Radeon RX 6800 XT is built on the RDNA 2.0 architecture with a Navi 21 chip, featuring 4608 shading units and 128 ROPs. Its boost clock of 2250 MHz and game clock of 2015 MHz provide the compute foundation for the measured results. The 16 GB of GDDR6 memory on a 256-bit bus delivers 512.0 GB/s of bandwidth, which is critical for Rust's texture streaming and world rendering. The data shows that at 4K Ultra, the average FPS of 37 is the lowest measured, while at 1080p Low it reaches 209 FPS, demonstrating a wide performance envelope.

The GPU's percentile rank of 85 against all GPUs places it in the upper tier, though its nearest rivals show mixed results. The NVIDIA RTX A1000 Mobile scores 1.5% higher, the Intel Arc A550M scores 2.5% lower, the NVIDIA GeForce RTX 5070 Ti scores 3% lower, and the AMD Radeon RX Vega 64 scores 3% lower in average benchmark scores. These deltas indicate that the RX 6800 XT sits in a competitive mid-to-high range, but the measured Rust performance at 4K suggests that the card is not overpowered for this title at maximum settings.

The VRAM capacity of 16 GB is not stressed by Rust's data requirements, as even at 4K Ultra, the card does not appear to run out of memory based on the FPS pattern — the drop from High to Ultra at 4K is 11 FPS, which is more consistent with compute limitations than memory swapping. The GPU's pixel rate of 288.0 GPixel/s and texture rate of 648.0 GTexel/s provide the fill rate needed for high-resolution rendering, but the 4K Ultra result of 37 FPS shows that the card is approaching its limits in this scenario.

Settings Recommendations

Based on the measured FPS rows, the Medium preset offers the best balance of visual quality and performance across all resolutions. At 1080p, Medium delivers 140 FPS with a minimum of 119 FPS, which is smooth and leaves headroom for dips. At 1440p, Medium produces 97 FPS with a minimum of 82 FPS, which is still playable and visually rich. At 4K, Medium drops to 57 FPS with a minimum of 49 FPS, which is marginal but usable for less competitive play.

For users prioritizing frame rate, Low settings at 1440p provide 144 FPS, which is exactly double the 4K High result of 72 FPS (though this specific 72 FPS figure is not in the pack — the 4K High is 48 FPS, so the comparison is 144 vs 48). The Low preset at 1440p is the highest combination of resolution and speed that stays above the 144 FPS threshold, making it ideal for high-refresh monitors. At 1080p, Low reaches 209 FPS, which exceeds the refresh rate of most displays, so Medium at 140 FPS is a better trade-off for visual fidelity.

The High preset is a reasonable middle ground at 1080p with 119 FPS, but at 1440p it falls to 82 FPS, and at 4K it drops to 48 FPS. These numbers suggest that High is only recommended for 1080p gaming, as the visual improvements over Medium do not justify the FPS loss at higher resolutions. Ultra settings are the most demanding, with 90 FPS at 1080p, 62 FPS at 1440p, and 37 FPS at 4K — these are only viable for users who prioritize maximum visuals over smoothness.

How This Combo Ranks

The combination of the AMD Ryzen 7 9700X and AMD Radeon RX 6800 XT ranks 1118 out of 3723 tested combos for Rust. This places the combo in the top 30% of all configurations tested, indicating that it is a capable pairing for this title. The rank of 1118 suggests that there are 1117 other combos that perform better in Rust, which is expected given that the RX 6800 XT is an end-of-life product and the Ryzen 7 9700X is a mid-range CPU.

The CPU's percentile rank of 86 against all CPUs is higher than the GPU's percentile rank of 85, suggesting that the processor is slightly more capable relative to its peers. This is reflected in the benchmark scores: the CPU's avgBenchmarkScore is 37943, while the GPU's is 48477. The nearest CPU rivals show very small deltas — the Intel Core i9-14901E is only 0.1% higher, the AMD Ryzen AI 9 HX 370 is 0.1% higher, the Intel Core 5 211E is 0.3% higher, and the AMD Ryzen AI Embedded P132 is 0.4% higher. This tight grouping indicates that the Ryzen 7 9700X is highly competitive in its class.

The combo's rank of 1118 out of 3723 means that 2605 combos perform worse. This is a strong position, but it also shows that there is significant room for improvement — likely by pairing the CPU with a more powerful GPU. The data indicates that the GPU is the more limiting component in this pairing, especially at higher resolutions where the FPS drops are most pronounced.

CPU Role

The AMD Ryzen 7 9700X is an 8-core, 16-thread processor based on the Zen 5 architecture with a 4 nm process node. Its base clock of 3.80 GHz and boost clock of 5.50 GHz provide substantial single-thread performance, which is critical for Rust's game logic and world simulation. The CPU's 32 MB of shared L3 cache and dual-channel DDR5 memory support with 89.6 GB/s bandwidth help feed the GPU with data efficiently.

In Rust, the CPU's role is primarily to handle the physics, player interactions, and server-side calculations. The measured FPS at 1080p Low of 209 FPS shows that the CPU is not the limiting factor at this resolution — the GPU is still able to render frames faster than the CPU can feed it. However, at 4K Ultra with 37 FPS, the CPU has plenty of headroom, as the GPU is clearly the bottleneck. The single-thread benchmark scores, such as 2211 in Cinebench R23 single-core and 3023 in Geekbench single-core, indicate strong per-core performance that supports Rust's single-threaded tendencies.

The CPU's nearest rivals, such as the Intel Core i9-14901E and AMD Ryzen AI 9 HX 370, show only 0.1% differences in average benchmark scores, meaning that swapping the CPU would not significantly change Rust performance. The 8 cores and 16 threads are sufficient for Rust's multi-threaded aspects, but the game's reliance on single-thread performance means that the boost clock of 5.50 GHz is a key asset. The 65 W TDP and active production status suggest that this CPU is efficient and current.

Measured FPS Breakdown

At 1920x1080, the measured results show a clear progression across presets. Low settings produce an average of 209 FPS, which is the highest measured in the entire dataset. Medium settings drop to 140 FPS with a minimum of 119 FPS and a maximum of 162 FPS, providing a consistent range. High settings reach 119 FPS, and Ultra settings fall to 90 FPS. The delta between Low and Ultra at 1080p is 119 FPS, demonstrating the significant impact of graphical presets on this resolution.

At 2560x1440, the same pattern holds but with lower absolute numbers. Low settings produce 144 FPS, Medium drops to 97 FPS with a minimum of 82 FPS and a maximum of 111 FPS, High reaches 82 FPS, and Ultra falls to 62 FPS. The delta between Low and Ultra at 1440p is 82 FPS, which is smaller than at 1080p, indicating that the GPU is becoming more of a limiting factor. The Medium preset's minimum of 82 FPS is equal to the High preset's average, showing that Medium provides better frame consistency.

At 3840x2160, the results show the GPU's limitations most clearly. Low settings produce 85 FPS, Medium drops to 57 FPS with a minimum of 49 FPS and a maximum of 66 FPS, High reaches 48 FPS, and Ultra falls to 37 FPS. The delta between Low and Ultra at 4K is 48 FPS, which is the smallest absolute difference but the largest percentage drop. The Medium preset at 4K has a minimum of 49 FPS, which is just above the High preset's average of 48 FPS, suggesting that Medium is the recommended preset for 4K if playability is the goal.
