Rust

The AMD Ryzen 5 7400F and AMD Radeon RX 570 combination presents a stark picture for running Rust, a survival title that is notoriously demanding on both CPU and GPU subsystems. The recorded data shows a system that is capable of playable frame rates only under the most restrictive conditions, and the gap between its performance and the 60 FPS threshold widens dramatically as resolution increases. The benchmark results indicate a pairing where the aging Polaris GPU is the primary bottleneck, holding back a modern Zen 4 processor.

Measured FPS Breakdown

At 3840x2160 (4K), the data reveals a performance envelope that is entirely below the playable threshold. The average frame rates are consistently poor across all presets. Running at Low settings yields an average of 27 FPS, which drops to 18 FPS on Medium (with a minimum of 15 FPS and a maximum of 21 FPS). The High preset produces an average of just 15 FPS, and the Ultra preset falls to 12 FPS. These figures are all far below the 60 FPS playable threshold, indicating that 4K is not a viable option for this hardware in Rust.

Moving down to 2560x1440 (1440p), the situation improves but remains fundamentally unplayable. The Low preset averages 46 FPS, which is the best result at this resolution but still 14 FPS short of the target. The Medium preset averages 31 FPS, with a minimum of 26 FPS and a maximum of 35 FPS. High settings yield an average of 26 FPS, while the Ultra preset drops to an average of 20 FPS. No setting at 1440p manages to clear the 60 FPS bar, and the data suggests that even the minimum frame rates would frequently dip into the low 20s and 30s, which would be a jarring experience.

At 1920x1080 (1080p), the resolution where this combination is most competitive, we finally see a preset cross the 60 FPS threshold. The Low preset achieves an average of 66 FPS, which is the only playable configuration recorded for this system. The Medium preset averages 44 FPS, with a minimum of 38 FPS and a maximum of 51 FPS, showing that it is not far from the threshold but still fails to maintain a consistent 60 FPS. The High preset averages 38 FPS, and the Ultra preset averages 29 FPS. The scaling from Low to Medium at 1080p is a drop of 22 FPS, which is a significant penalty for the visual upgrade, and the data implies that the GPU is struggling to fill the extra frames.

The data across all resolutions shows a clear pattern of diminishing returns as settings are increased. The step from Low to Medium consistently costs roughly 30-40% of the average frame rate, while the step from High to Ultra costs a similar proportional amount. This indicates a GPU that is heavily saturated at even moderate settings, with the minimum FPS figures at Medium settings showing that frame pacing can be inconsistent.

CPU and GPU Roles

The benchmark results indicate that the AMD Radeon RX 570 is the decisive performance limiter in this pairing for Rust. The evidence for this comes from the frame rate scaling between resolutions. When the resolution drops from 1440p to 1080p, the average frame rate on the Low preset increases from 46 FPS to 66 FPS, a jump of 43%. This substantial increase in performance with a lower pixel count is a classic symptom of a GPU-bound scenario. If the CPU were the primary constraint, the frame rate would remain relatively flat across resolutions, as the CPU workload would be similar.

Further evidence comes from the performance drop at higher presets. The gap between Low and Ultra at 1080p is 37 FPS (from 66 to 29 FPS). This massive penalty for higher graphical fidelity is attributed almost entirely to the GPU's limited shading power and 4 GB of VRAM, which is likely insufficient for the high-resolution textures and draw distances in Rust. The Ryzen 5 7400F, with its Zen 4 architecture and high single-thread score of 3072 in Cinebench R23, is more than capable of feeding the GPU in most scenarios, but the data shows it cannot overcome the GPU's inherent limitations.

The CPU's role becomes more apparent at 1080p Low, where the GPU is least stressed. The 66 FPS average is likely close to the maximum sustainable throughput of the RX 570, and the CPU is able to keep up with the game's logic threads. The Ryzen 5 7400F's multi-core performance, evidenced by a Cinebench R23 score of 21765, suggests it has the headroom for Rust's complex simulation and entity processing, but this headroom is irrelevant when the GPU cannot render frames fast enough to utilize it. In this configuration, the GPU is the clear bottleneck at all resolutions and settings, and the CPU's performance is effectively masked by the GPU's inability to keep pace.

FAQ

Q: Can this system run Rust at 4K resolution?

A: No. The recorded data shows no playable settings at 3840x2160. The highest average frame rate is 27 FPS on Low settings, which is far below the 60 FPS playable threshold.

Q: What is the best performance this combo can achieve?

A: The best recorded result is 66 FPS average at 1920x1080 with the Low preset. This is the only configuration that meets or exceeds the 60 FPS playable threshold.

Q: How much better is 1080p Low compared to 1440p Low?

A: At 1080p Low, the average frame rate is 66 FPS, which is 20 FPS higher than the 46 FPS average at 1440p Low. This represents a 43% performance increase when dropping from 1440p to 1080p.

Q: Is the CPU or GPU the limiting factor?

A: The data strongly indicates the AMD Radeon RX 570 GPU is the primary bottleneck. The frame rate scales significantly with resolution and settings, which is a sign of a GPU-bound workload. The Ryzen 5 7400F's performance is not the limiting factor in this configuration.

Q: What are the minimum frame rates like at Medium settings?

A: The minimum frame rates are only recorded for the Medium preset. At 1080p Medium, the minimum is 38 FPS, at 1440p Medium it is 26 FPS, and at 4K Medium it is 15 FPS. These lows can cause noticeable stuttering.

Q: Does the Ultra preset ever hit 60 FPS?

A: No. The Ultra preset never achieves a playable frame rate at any resolution. The highest average for Ultra is 29 FPS at 1080p, which is less than half of the 60 FPS target.

The Verdict

This combination can run Rust, but only just. The verdict by resolution is clear: 1920x1080 is the only playable resolution, and it is playable only with the Low preset, which achieves an average of 66 FPS. This crosses the 60 FPS threshold, but the margin is slim, and it is reasonable to expect dips below 60 FPS in busy scenes, given that the Medium preset at this resolution has a 38 FPS minimum.

At 2560x1440, the system is not playable. The best average frame rate is 46 FPS on Low settings, which is still 14 FPS below the target, and the minimum frame rates would likely be in the 30s, causing frequent and noticeable hitches. At 3840x2160, the system is completely unplayable, with all presets averaging below 30 FPS. The data suggests that this is a system for 1080p gaming only, and even then, users must compromise heavily on visual fidelity to achieve a stable frame rate. The 4 GB VRAM and the GPU's overall performance level are the key reasons for these limitations.

How This Combo Ranks

The recorded data places this specific combination at rank 3553 out of 3723 tested combos for Rust. This puts it in the bottom 5% of all tested systems, indicating that while it is technically capable of running the game, its performance is among the lowest in the database. This low ranking is consistent with the measured frame rates, which are only playable at the lowest settings and resolution. The rank reflects a system that is far more suited to older or less demanding titles, and for Rust specifically, it is a marginal experience. The data shows that the vast majority of other tested CPU and GPU pairings will deliver a better frame rate, often at higher settings and resolutions.

Best Settings per Resolution

Based on the measured data, the best settings for each resolution are determined by the most demanding preset that still maintains an average of at least 60 FPS.

At 1920x1080, the Low preset is the only configuration that meets the 60 FPS threshold, with an average of 66 FPS. This is the recommended setting for a playable experience.

At 2560x1440 and 3840x2160, no settings are playable. The verdict data confirms that there are no playable settings at these resolutions, as the average frame rates for all presets are below 60 FPS. Users attempting to run these resolutions would have to accept a sub-60 FPS experience, which the data shows would be a significant compromise.

Similar Performance Alternatives

Looking at the nearest rivals in the database, there are several hardware combinations that would behave similarly to this setup. For the CPU, the AMD Ryzen 5 7400F's closest rivals are the Intel Core i5-14600T, the Intel Core Ultra 7 155H, the AMD Ryzen 7 PRO 6850H, and the AMD Ryzen AI 7 PRO 360. These processors all have average benchmark scores within 0.3% of the Ryzen 5 7400F, meaning their performance in Rust would be virtually identical. Since the GPU is the bottleneck, swapping the CPU for any of these would not change the frame rates in this game.

For the GPU, the AMD Radeon RX 570's nearest rivals include the AMD Radeon RX 6800M, the AMD Radeon R9 M295X, the AMD Radeon RX 470, and the NVIDIA Quadro RTX 8000. The AMD Radeon RX 470 is particularly relevant, as it has a delta of -0.8% in average benchmark score, indicating it would deliver nearly the exact same performance as the RX 570 in Rust. The other rivals show a range of -0.4% to 1.2% in score, suggesting that any of these GPUs would result in a similar frame rate experience, all constrained by the same level of graphics processing power. The data implies that users with any of these GPU alternatives would see very similar results at the same settings and resolutions.
