Rust

The AMD Ryzen 7 5800X paired with the AMD Radeon RX 6700 XT delivers a playable yet demanding experience in Rust, with frame rates that hinge dramatically on both resolution and preset. The data shows a system that can push high refresh rates at 1080p with lower settings but quickly succumbs to the combined weight of the game’s CPU-intensive simulation and GPU load at higher resolutions. This analysis breaks down the measured FPS, the roles of each component, and what the numbers imply for tuning.

Resolution Scaling

The measured FPS reveals a steep performance cliff as resolution climbs, indicating a shift in bottleneck from the CPU to the GPU. At 1920x1080 with Low settings, the combo achieves 162.7 FPS, but dropping to 2560x1440 Low yields 113.5 FPS, a 30% reduction. Moving to 3840x2160 Low, the average falls to 65.7 FPS, which is 42% lower than the 1440p result and 60% lower than the 1080p baseline. This scaling pattern is classic: the RX 6700 XT’s pixel throughput is the limiting factor at higher resolutions, while the 5800X’s strong single-thread performance keeps the frame rate high at 1080p.

The gap widens further on higher presets. At Ultra settings, the 1080p result is 71 FPS, but 1440p Ultra drops to 46.6 FPS, and 4K Ultra craters to 29.2 FPS. The 1440p to 4K transition on Ultra represents a 37% loss, whereas the same resolution jump on Low only costs 42%—but the absolute numbers are far more punishing on Ultra. The data suggests that Rust’s rendering load scales non-linearly with resolution when using higher-quality presets, likely due to increased draw calls and shading complexity. For players targeting 4K, even Low settings (65.7 FPS) are borderline, while 1440p Ultra is barely playable and 4K Ultra is not viable for smooth gameplay.

GPU Role

The AMD Radeon RX 6700 XT is the primary driver of resolution-dependent performance, and its 12 GB of GDDR6 memory on a 192-bit bus with 384.0 GB/s bandwidth is a key asset. The card’s boost clock of 2581 MHz and game clock of 2424 MHz provide substantial compute throughput, evidenced by its 13.21 TFLOPS FP32 performance. In Rust, the GPU’s role becomes more pronounced as resolution increases; at 4K Ultra, the card’s pixel rate of 165.2 GPixel/s is clearly insufficient, yielding only 29.2 FPS. The 12 GB VRAM is not a limiting factor even at 4K, as the measured data shows no signs of memory-related stutters—the bottleneck is purely shader and pixel throughput.

The RX 6700 XT’s performance relative to its peers is interesting. Its average benchmark score is 33721, placing it at the 77th percentile among all GPUs. Its nearest rival is the AMD Radeon RX 6800, which scores 33493, a 0.7% difference. This proximity suggests that in Rust, the 6700 XT is performing near its expected tier, but the game’s engine favors raw pixel throughput over memory bandwidth—the 6700 XT’s 384.0 GB/s bandwidth is adequate, yet the card still falls to sub-30 FPS at 4K Ultra. The data implies that players should not expect the 12 GB VRAM to rescue high-resolution Ultra settings, as the compute units are simply overwhelmed.

Settings Recommendations

Based on the measured rows, the optimal settings depend on the target resolution and refresh rate. For 1080p, Medium settings at 111.8 FPS strike the best balance, offering a 19% improvement over High (94.2 FPS) while retaining visual fidelity. Low settings at 162.7 FPS are only recommended for competitive play, as the jump to 162.7 FPS is substantial but the visual downgrade is severe. At 1440p, Medium is the clear winner, producing 74.5 FPS—a 52% increase over High (67.1 FPS) and a 60% jump over Ultra (46.6 FPS). Low settings at 1440p reach 113.5 FPS, but the difference from Medium is 34%, making Medium the sweet spot for most users.

For 4K, the choice is stark. Low settings at 65.7 FPS are the only playable option, but even this is marginal for a 60 Hz display. Medium drops to 46 FPS, and High to 36.4 FPS, both below the 60 FPS target. Ultra at 29.2 FPS is not recommended. The data suggests that this combo is best suited for 1080p and 1440p gaming, where Medium or High presets provide a good experience. At 4K, players must accept Low settings or lower the resolution, as the GPU cannot sustain playable frame rates on higher presets.

How This Combo Ranks

The combo ranks 941 out of 1717 tested configurations, placing it in the 55th percentile of all combos. This is a middling result, reflecting the pairing of a high-end CPU from 2020 with a mid-range GPU from 2021. The CPU’s benchmark percentile is 84th among all processors, while the GPU sits at the 77th percentile, yet the combined result is dragged down by the GPU’s inability to feed high-resolution displays in Rust. The rank suggests that while the 5800X is capable of driving high frame rates at 1080p, the RX 6700 XT is the limiting factor, preventing the combo from reaching the top tiers.

Compared to other combos, this system is not a top performer in Rust, but it is also far from the bottom. The rank implies that many configurations with newer GPUs or higher-end cards will outperform it, particularly at 1440p and 4K. However, the 5800X’s strong multi-core performance (Cinebench R23 multi-core score of 23571) means that in CPU-bound scenarios, such as large multiplayer servers at 1080p, the combo can hold its own. The data indicates that for players prioritizing competitive 1080p play, this combo is adequate, but for 4K enthusiasts, it is a compromise.

Measured FPS Breakdown

The measured FPS data covers four resolutions and four settings, providing a clear picture of scaling. At 1920x1080, the results are: Low 162.7 FPS, Medium 111.8 FPS, High 94.2 FPS, and Ultra 71 FPS. The spread from Low to Ultra is 91.7 FPS, showing that settings have a massive impact at this resolution. At 2560x1440, the numbers are: Low 113.5 FPS, Medium 74.5 FPS, High 67.1 FPS, and Ultra 46.6 FPS. The spread narrows to 66.9 FPS, but the relative drop from Low to Ultra is 59%. At 3840x2160, the results are: Low 65.7 FPS, Medium 46 FPS, High 36.4 FPS, and Ultra 29.2 FPS. The spread is 36.5 FPS, and the Low-to-Ultra drop is 55%.

The data also shows how settings impact performance at each resolution. At 1080p, moving from Low to Medium costs 31% performance, while Medium to High costs 16%, and High to Ultra costs 25%. At 1440p, the jumps are: Low to Medium costs 34%, Medium to High costs 10%, and High to Ultra costs 31%. At 4K, the cost is: Low to Medium is 30%, Medium to High is 21%, and High to Ultra is 20%. This indicates that the largest performance penalty is often between Low and Medium, while the High-to-Ultra jump is consistently costly.

CPU Role

The AMD Ryzen 7 5800X plays a critical role in Rust’s performance, particularly at lower resolutions where the GPU is not the primary bottleneck. With 8 cores and 16 threads, the CPU’s Zen 3 architecture provides strong single-thread performance, as evidenced by its 3DMark single-thread score of 943 and Cinebench R23 single-core score of 3327. Rust is known to be CPU-intensive, especially in multiplayer scenarios with many entities, and the 5800X’s high boost clock of 4.70 GHz helps maintain high frame rates at 1080p Low, where the 162.7 FPS result is likely CPU-bound.

The CPU’s multi-threaded capabilities are also substantial, with a Cinebench R23 multi-core score of 23571 and a Passmark multithread score of 27732. This allows the CPU to handle background tasks and game logic without bottlenecking the GPU. However, the data shows that at higher resolutions, the CPU’s advantage diminishes, as the GPU becomes the limiting factor. The 5800X’s 32 MB L3 cache is beneficial for Rust’s large world data, and the 105 W TDP indicates efficient power delivery. The CPU’s percentile rank of 84th among all processors confirms its high-end status, but the combo’s overall rank of 941 shows that the GPU is the more significant constraint in this pairing.
