Rust

Measured FPS Breakdown

At 3840x2160, the Intel Core i5-12400F and AMD Radeon RX 570 combination delivers an average of 15 FPS on High settings, 27 FPS on Low settings, 18 FPS on Medium settings, and 12 FPS on Ultra settings. The only preset with recorded minimum and maximum values at this resolution is Medium, which ranges from 15 FPS to 21 FPS. These figures sit far below the 60 FPS playable threshold, indicating that 4K resolution is entirely out of reach for this hardware pairing in Rust.

Moving down to 2560x1440, the measured averages improve noticeably but remain sub-60 FPS across all presets. High settings produce an average of 26 FPS, Low settings reach 46 FPS, Medium settings hit 31 FPS, and Ultra settings drop to 20 FPS. The Medium preset at 1440p shows a minimum of 26 FPS and a maximum of 35 FPS, providing a narrow band of performance that still falls well short of smooth gameplay. The gap between Low and High at this resolution is 20 FPS, which underscores how heavily the GPU is taxed as visual quality increases.

At 1920x1080, the data shows a clear step up in performance. Low settings achieve an average of 66 FPS, which clears the 60 FPS playable threshold by a modest margin. High settings average 38 FPS, Medium settings average 44 FPS, and Ultra settings average 29 FPS. The Medium preset at 1080p records a minimum of 38 FPS and a maximum of 51 FPS, meaning even the most consistent preset below Low fails to hold 60 FPS. The jump from 1440p to 1080p at Low settings is substantial, from 46 FPS to 66 FPS, a 43% improvement that highlights how resolution scaling affects this older GPU architecture.

Across all resolutions, the pattern is consistent: only the lowest quality preset at the lowest tested resolution reaches the playable threshold. The average FPS deltas between settings grow as resolution decreases, suggesting that the RX 570 has more headroom at 1080p but still cannot sustain high or ultra quality levels.

CPU and GPU Roles

The benchmark results indicate that the AMD Radeon RX 570 is the dominant performance limiter in this pairing for Rust. Evidence comes from the scaling behavior across resolutions. At 3840x2160, the average FPS ranges from 12 to 27 depending on preset, while at 1920x1080 the range expands to 29 to 66. If the Intel Core i5-12400F were the bottleneck, the frame rates would remain relatively flat as resolution changes, since the CPU workload per frame stays similar. Instead, the large drops from 1080p to 1440p and further to 4K point directly at GPU-bound rendering.

The CPU's compute capabilities, as recorded in the database, show a strong single-threaded score of 909 in 3DMark single-thread and a multithreaded score of 5912 in 3DMark max threads. These figures place the i5-12400F in the 73rd percentile among all CPUs, indicating it has ample processing headroom for a game like Rust, which is known to be CPU-sensitive in server-side simulation. However, the measured FPS data does not show any resolution where the CPU becomes the limiting factor, because the RX 570's 4 GB GDDR5 memory and 224.0 GB/s bandwidth constrain frame production well before the CPU's six cores and twelve threads are saturated.

The preset scaling further confirms the GPU-bound nature. At 1920x1080, moving from Low to Medium costs 22 FPS on average (66 to 44), from Medium to High costs 6 FPS (44 to 38), and from High to Ultra costs 9 FPS (38 to 29). The steepest drop occurs at the lowest quality step, which is typical for a GPU that lacks the shading units and texture throughput for higher settings. The RX 570 has 2048 shading units and 128 texture mapping units, and its 5.095 TFLOPS FP32 throughput is modest by modern standards. At 1440p and 4K, the same preset transitions show even larger absolute losses, such as from Low to Medium at 1440p costing 15 FPS (46 to 31), which reinforces that the GPU is working far beyond its comfortable envelope.

For the CPU side, the i5-12400F's 3DMark 16-thread score of 5895 and 8-thread score of 4779 suggest that Rust's multithreaded workload would be handled without major stalls. The Cinebench R23 multicore score of 12380 also indicates strong sustained performance. Yet the measured FPS never exceeds 66 even at the lowest settings, which is a clear sign that the GPU is the ceiling. If the CPU were the bottleneck, we would expect to see similar FPS numbers at 1080p Low and 1440p Low, but the data shows 66 versus 46, a 20 FPS difference that can only be attributed to GPU resolution scaling.

Similar Performance Alternatives

Looking at the nearest rivals for the Intel Core i5-12400F, the database lists the AMD Ryzen 5 7535HS with an average score of 19047 and a delta of 0%, the Intel Core 3 201E at 19056 with a delta of -0.1%, the Intel Core i5-1335U at 18982 with a delta of 0.3%, and the AMD EPYC 7773X at 18979 with a delta of 0.3%. These processors would behave nearly identically to the i5-12400F in Rust, meaning the GPU would still be the limiting factor. A user swapping the i5-12400F for any of these rivals would see no meaningful FPS change in the measured scenarios, since the RX 570 cannot be fed faster by a slightly different CPU.

For the AMD Radeon RX 570, the nearest rivals include the AMD Radeon RX 6800M with an average score of 28874 and a delta of -0.4%, the AMD Radeon R9 M295X at 28580 with a delta of 0.7%, the AMD Radeon RX 470 at 28996 with a delta of -0.8%, and the NVIDIA Quadro RTX 8000 at 28421 with a delta of 1.2%. The RX 470 is the most relevant comparison, as it shares the same Polaris architecture generation and would deliver nearly the same frame rates in Rust. The RX 6800M, despite being a laptop GPU, scores within 0.4% of the RX 570 in the database's aggregate benchmark, so it would also produce similar sub-60 FPS results at 1080p except for the Low preset. The Quadro RTX 8000, a workstation card, would not offer a gaming advantage in this context despite its higher average score.

For users seeking a smoother Rust experience, the data suggests that any of these GPU rivals would still struggle to reach 60 FPS at Medium or higher settings. The only path to higher frame rates would require a GPU with significantly better benchmark scores, but the database does not list such alternatives within the nearest rivals for this combination.

FAQ

Q: Can the Intel Core i5-12400F and AMD Radeon RX 570 run Rust at 1920x1080?

A: Yes, but only on Low settings, where the measured average FPS is 66. All other presets at 1080p fall below the 60 FPS playable threshold: High averages 38 FPS, Medium averages 44 FPS, and Ultra averages 29 FPS.

Q: What is the best resolution for this PC to play Rust?

A: The only resolution and preset combination that clears 60 FPS is 1920x1080 with Low settings. At 2560x1440, even Low settings only reach an average of 46 FPS, and at 3840x2160, the maximum average across any preset is 27 FPS.

Q: Is the Intel Core i5-12400F or the AMD Radeon RX 570 the bottleneck in Rust?

A: The benchmark data indicates the GPU is the limiting factor. The large FPS drops as resolution increases, from 66 FPS at 1080p Low to 46 FPS at 1440p Low to 27 FPS at 4K Low, show that the RX 570 cannot maintain frame rates as pixel count grows, while the CPU's strong benchmark scores suggest it has spare capacity.

Q: What frame rates can I expect on Medium settings at 1440p?

A: The recorded average is 31 FPS, with a minimum of 26 FPS and a maximum of 35 FPS. This is well below the 60 FPS playable threshold and would likely feel stuttery during intense gameplay moments.

Q: How does this combo rank compared to other tested systems in Rust?

A: This combination ranks 3553 out of 3723 tested combos in the database, placing it in the lower percentile of systems. This reflects the RX 570's age and limited memory bandwidth for a game like Rust.

Q: Does the RX 570's 4 GB memory affect gameplay at 4K?

A: While the database records a 4 GB GDDR5 memory size, the measured FPS at 3840x2160 never exceeds 27 FPS on any preset. The memory capacity likely contributes to the low performance, but the data does not isolate memory usage from GPU compute limits.

The Verdict

This PC can run Rust, but only under very specific conditions. According to the verdict by resolution, at 1920x1080 the system achieves playable performance solely on Low settings, with an average of 66 FPS. At 2560x1440, no preset clears the 60 FPS threshold, and the same applies to 3840x2160. The playable settings list for 1080p contains only "Low", with the best settings recorded as "Low" and the average FPS at that setting being 66.

For gamers who insist on higher visual fidelity, this combination will not deliver a smooth experience. Even Medium settings at 1080p drop to 44 FPS, which is below the playable mark. The data shows a clear trade-off: to hit 60 FPS, the user must accept the lowest quality preset. At 1440p and 4K, the system is not viable for playable frame rates regardless of settings, with the best case at 1440p being 46 FPS on Low and at 4K being 27 FPS on Low.

The overall assessment is that this hardware can handle Rust at entry-level settings for 1080p displays, but it falls short of what most players would consider a comfortable gaming experience. The RX 570's age and the game's demanding rendering make it a marginal setup for Rust as of the recorded data.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Low, with a recorded average of 66 FPS. No other preset at this resolution reaches the playable threshold, so Low is the only viable option.

At 2560x1440, there is no preset that maintains 60 FPS. The closest is Low at 46 FPS, which falls 14 FPS short of the playable mark. Medium averages 31 FPS, High averages 26 FPS, and Ultra averages 20 FPS, all of which are far too low.

At 3840x2160, the situation is worse. Low settings average 27 FPS, Medium averages 18 FPS, High averages 15 FPS, and Ultra averages 12 FPS. None of these come close to 60 FPS, and the database lists no best settings for this resolution.

For users who must play at 1080p, Low is the only choice for smooth gameplay. If they are willing to accept lower frame rates, Medium at 44 FPS is the next step up, but it will not provide the same fluidity.

How This Combo Ranks

The Intel Core i5-12400F and AMD Radeon RX 570 combination ranks 3553 out of 3723 tested combos in the database for Rust. This places it in the bottom 5% of all tested systems, which aligns with the measured FPS data showing only a single playable configuration. The rank reflects the GPU's limited capabilities for this specific game, as the CPU is comparatively strong.

The low rank is driven primarily by the RX 570's inability to handle Rust's rendering demands at higher settings or resolutions. Even though the i5-12400F sits in the 73rd percentile among CPUs, the GPU's 74th percentile among GPUs does not translate into playable performance because Rust is particularly demanding on memory bandwidth and shading throughput. The combination's aggregate benchmark scores, with the CPU averaging 19039 and the GPU averaging 28766, suggest balanced mid-range hardware, but the in-game results reveal that Rust is an outlier where this pairing struggles.

For context, a system ranked higher in the database would need a GPU with significantly more compute power, as the CPU is not the limiting factor. The data shows that this combo is only suitable for 1080p Low gaming in Rust, and even then, the 66 FPS average leaves little headroom for demanding scenes with many players or complex bases.
