Rust

Rust is a demanding survival title, and the combination of the AMD Ryzen 5 5600F and NVIDIA GeForce RTX 4080 SUPER produces a wide range of performance depending on your resolution and settings. The data shows a system that is exceptionally capable at 1080p and 1440p, but which begins to feel the strain of 4K Ultra settings. The measured FPS figures provide a clear picture of where this pairing excels and where you will need to make compromises to maintain a high refresh rate experience.

Resolution Scaling

The performance drop from 1080p to 4K is significant and reveals the shifting bottleneck between the CPU and GPU. At 1080p with High settings, the system delivers 133 FPS. Moving to 1440p High, the average only drops to 112 FPS, a relatively modest 16% reduction. This indicates that at these resolutions, the CPU is still doing a substantial amount of the heavy lifting, and the RTX 4080 SUPER has enough headroom to keep frames high.

However, the scaling steepens dramatically when moving to 4K. At 3840x2160 with High settings, the average FPS falls to 66. This is a 41% drop from the 1440p figure, clearly demonstrating that the GPU is now becoming the primary limiting factor. The RTX 4080 SUPER is a powerful card, but the sheer pixel count of 4K requires immense fill rate and shading power, which is where the data shows the performance cliff.

The scaling trend is consistent across all settings presets. For instance, with Ultra settings, the system achieves 120 FPS at 1080p, which is excellent. At 1440p Ultra, this drops to 85 FPS, and at 4K Ultra, it plummets to 50 FPS. This pattern strongly suggests that for 4K gaming on this title, the GPU is working at its limit, especially when the highest quality presets are enabled. The difference between 1080p and 4K is not linear; it's an exponential increase in workload that the data shows the GPU struggles to maintain.

The data indicates that users targeting 4K will need to be more mindful of their settings. While the CPU is a solid 6-core/12-thread part, it is the GPU that dictates the ceiling at higher resolutions. The 41% drop from 1440p to 4K highlights that while the CPU can keep up with the game's logic and draw calls, the GPU cannot render the frames fast enough. The scaling from 1080p to 1440p is much more graceful, suggesting that 1440p is the sweet spot for this combination if you want to maintain a high refresh rate without turning down many graphical features.

CPU Role

The AMD Ryzen 5 5600F is a 6-core, 12-thread processor based on the Zen 3 architecture. It has a base clock of 3.00 GHz and a boost clock of 4.00 GHz. In the context of Rust, which is known for being CPU-intensive, this processor proves to be a very capable partner for the RTX 4080 SUPER. The benchmark results show that at 1080p Low settings, the system hits 164 FPS, which is the highest average recorded in the data. This high frame rate at a low resolution, where the GPU load is minimal, indicates that the CPU is able to feed the graphics card with enough data to avoid being a major bottleneck.

The CPU's performance in the PassMark benchmarks is solid, with a multi-thread score of 19236 and a single-thread score of 2872. It sits in the 85th percentile of all CPUs, which is a strong showing. Its nearest rivals include the Intel Core Ultra 5 225 and the AMD Ryzen 5 5500X3D, with the 5600F performing within 0.5% of both. This data suggests that the 5600F is a well-balanced processor that provides no significant disadvantage in gaming workloads when paired with a high-end GPU.

The importance of the CPU is most evident when looking at the frame rates at 1080p. The difference between Low (164 FPS) and Ultra (120 FPS) at 1080p is 44 FPS. This gap is primarily due to the increased CPU workload associated with higher settings, which involve more complex scene geometry and physics calculations. However, it is not a crippling difference, meaning the CPU has enough headroom to handle the increased draw calls. The data implies that the 5600F is not holding back the RTX 4080 SUPER at 1080p, as even the most demanding settings produce a very playable 120 FPS.

At 4K, the CPU's role diminishes. While the absolute FPS is lower, the drop from Low (116 FPS) to High (66 FPS) is much more pronounced. This is a 43% reduction, which is a direct result of the GPU becoming the performance limiter. The CPU is still doing its job, but the GPU is taking significantly more time to render each frame. The data shows that for this game, the 5600F is an excellent match for this GPU, providing enough processing power to ensure that the GPU is the primary factor in performance at higher resolutions.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is the clear workhorse in this pairing. It features 16 GB of GDDR6X memory on a 256-bit bus, providing a substantial 736.3 GB/s of bandwidth. Its boost clock is 2550 MHz, and it is based on the Ada Lovelace architecture. In Rust, the GPU's role becomes increasingly dominant as resolution and settings are increased. The data shows that the card is powerful enough to deliver high frame rates at 1440p, but it is pushed to its limits at 4K with the highest settings.

The RTX 4080 SUPER performs at the 86th percentile of all GPUs, with an average benchmark score of 54209. Its nearest rival is the standard RTX 4080, from which it is only 0.1% slower, and it is ahead of the AMD Radeon RX 6750 GRE 12 GB by 2.7%. This places the SUPER variant firmly at the top end of the performance spectrum. The 16 GB of VRAM is more than sufficient for Rust, which is unlikely to be a limiting factor even at 4K with maximum textures, as the game's art style is not texture-heavy.

The GPU's performance scaling is the key takeaway from the measured data. At 1440p Medium, the card produces 125 FPS, which is excellent for a smooth experience. However, at 4K Medium, the average drops to 78 FPS. This is a 37.6% reduction, which is a clear sign that the GPU is the limiting component at this resolution. The data suggests that the card's raw compute power is being saturated by the 4K pixel count, despite having a high bandwidth and ample VRAM.

The RTX 4080 SUPER's performance at 4K Low (116 FPS) versus 4K High (66 FPS) shows a massive 50 FPS swing. This indicates that the card has a large performance reserve when graphical effects are reduced. The data demonstrates that the GPU can handle the resolution, but not the combination of resolution and high-fidelity effects simultaneously. For users who want to play at 4K, the card is capable, but it will require a willingness to lower settings to achieve high refresh rates, as the Ultra preset only yields 50 FPS.

Measured FPS Breakdown

The measured FPS data provides a complete picture of this system's performance in Rust. The numbers are clear and show a predictable pattern of decreasing performance with increasing resolution and settings.

1080p: At 1920x1080, the system is exceptionally fast. The Low preset yields an average of 164 FPS, which is outstanding. The Medium preset averages 141 FPS, with a minimum of 120 FPS and a maximum of 162 FPS. The High preset drops slightly to 133 FPS. The Ultra preset, while the most demanding, still produces a very playable average of 120 FPS. This data shows that at 1080p, the system is more than capable of driving high refresh rate monitors, even with the most demanding settings.

1440p: Moving to 2560x1440, performance remains strong. The Low preset averages 145 FPS, which is a minor 11.6% reduction from 1080p. The Medium preset averages 125 FPS, with a minimum of 106 FPS and a maximum of 143 FPS. The High preset averages 112 FPS. The Ultra preset, however, sees a more significant drop to 85 FPS. This indicates that while 1440p is very playable, the Ultra preset is where the GPU starts to feel the pressure, but it is still a great experience.

4K: At 3840x2160, the performance cliff is apparent. The Low preset averages 116 FPS, which is still very good. The Medium preset averages 78 FPS, with a minimum of 66 FPS and a maximum of 90 FPS. The High preset averages 66 FPS. The Ultra preset is the most demanding, dropping the average to just 50 FPS. This data shows that 4K is only really viable for high refresh rates when using the Low preset. For higher quality settings, users will have to accept frame rates in the 50-78 FPS range, which is still playable but not ideal for competitive play.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on your target resolution and refresh rate.

For users with a 1080p 144Hz or 165Hz monitor, the Ultra preset is the best choice. With an average of 120 FPS, you will be able to fully utilize your monitor's refresh rate while enjoying the highest visual fidelity. The performance is smooth enough for most games, and the visual upgrade over High is worthwhile.

For users with a 1440p 144Hz monitor, the High preset is the recommended starting point. It delivers an average of 112 FPS, which is close to the refresh rate limit. If you prefer maximum visual quality, the Ultra preset is also viable, with an average of 85 FPS, which is still very smooth. The Medium preset also offers an excellent experience with 125 FPS, but it is not necessary for a good experience at this resolution.

For users with a 4K 60Hz monitor, the High preset is the best choice for a balance of quality and performance. It delivers an average of 66 FPS, which is above the 60 FPS target for a standard monitor. If you need to guarantee a locked 60 FPS, the Medium preset is safer, with an average of 78 FPS and a minimum of 66 FPS. The Ultra preset is not recommended, as its 50 FPS average will be noticeably less smooth on a 60Hz display.

The data clearly shows that the Low preset is only necessary for users targeting very high refresh rates (165Hz+) at 4K, where it is the only preset that can consistently exceed 100 FPS. For most users, the High preset offers the best compromise between visual quality and performance across all resolutions. The system is well-balanced, and the settings recommendations above allow you to tune it to your specific display and performance preferences.
