Rust

Intel Core i5-14400F and AMD Radeon RX 580 is a pairing that sits near the bottom of the database’s tested combinations for Rust. The combo ranks 3425 out of 3723 tested combos, placing it in the 8th percentile of all recorded systems. This is not a configuration built for high-refresh or high-fidelity Rust play, but the data shows it can handle the game at 1080p with the right settings. The CPU is a strong modern part, while the GPU is an older budget-oriented card, and that mismatch defines everything about the performance profile.

How This Combo Ranks

The recorded rank of 3425 out of 3723 combos puts this system firmly in the lower tier of the database’s Rust results. Only roughly 300 tested combinations perform worse. This rank is driven almost entirely by the GPU, as the RX 580’s compute and graphics scores are modest by current standards. The CPU, by contrast, is a high-performing part: the Core i5-14400F sits in the 83rd percentile among all CPUs in the database, with an average benchmark score of 32279. That is a wide gap between the two components, and in Rust the weaker link becomes the limiting factor at every resolution and preset.

In practical terms, this rank means the combo is not competitive for Rust players who want smooth gameplay at 1440p or 4K. The data shows no playable settings at 2560x1440 or 3840x2160, meaning the system cannot hold 60 FPS at any preset at those resolutions. At 1080p, only the Low preset reaches the playable threshold. The rank reflects that reality: this is a 1080p-low system for Rust, nothing more. Compared to the broader field, the combo is closer to the bottom than the middle, which is expected given the RX 580’s age and the game’s demanding nature.

CPU and GPU Roles

The division of labor in this combo is clear from the benchmark data. The Core i5-14400F is a 10-core, 16-thread processor with a boost clock of 4.70 GHz, and its multi-core scores are strong: 21645 in Cinebench R23 multi-core, 9090 in Cinebench R20 multi-core, and 2181 in Cinebench R15 multi-core. Single-core performance is also solid, with 3055 in Cinebench R23 single-core and 3701 in Passmark single-thread. These numbers indicate the CPU has ample headroom for Rust’s simulation and networking threads.

The RX 580, however, is the bottleneck. Its Passmark G3D score is 8813, which places it in the 53rd percentile among all GPUs, and its 3DMark Steel Nomad DX12 score is 1005. The GPU’s FP32 throughput is 6.175 TFLOPS, and it has 8 GB of GDDR5 memory on a 256-bit bus with 256.0 GB/s bandwidth. Those are capable numbers for 2017 hardware, but Rust’s rendering load outpaces them at higher resolutions.

The scaling between resolutions confirms the GPU’s dominance in determining performance. At 1080p Low, the combo achieves 73.7 FPS average. Dropping to 1440p Low reduces that to 49.5 FPS, a 33% decline. At 4K Low, the average falls to 31.7 FPS, another 36% drop. This pattern shows that the GPU is saturated even at Low settings, and the CPU is not the limiting factor. If the CPU were the constraint, the FPS would not drop so steeply as resolution increases, because the CPU workload for a given scene is similar regardless of resolution. The data indicates the RX 580 simply runs out of pixel-pushing capability.

At higher presets, the GPU load increases further, and the FPS drops accordingly. For example, at 1080p, moving from Low to Medium reduces the average from 73.7 to 50.7 FPS, then to 44.7 at High, and finally to 31.2 at Ultra. The CPU’s role becomes more visible at lower resolutions and lower presets, where the GPU has less work per frame. Even at 1080p Low, the CPU is not breaking a sweat, as the 73.7 FPS figure is well within the i5-14400F’s capabilities. The recorded data suggests that upgrading the GPU would yield significant gains across all resolutions, while a CPU upgrade would do little for this game.

Measured FPS Breakdown

The database provides average FPS for each resolution and preset combination, with no minimum or maximum FPS recorded. The following numbers are the only measured values.

At 3840x2160 (4K), the results are uniformly below playable:

• Low: 31.7 FPS average
• Medium: 18.7 FPS average
• High: 19.5 FPS average
• Ultra: 12.0 FPS average

The 4K Low result is the best at that resolution, but 31.7 FPS is less than half the 60 FPS playable threshold. The Ultra preset at 12.0 FPS is barely a slideshow. None of these are viable for actual gameplay.

At 2560x1440 (1440p), the numbers improve but remain below 60 FPS:

• Low: 49.5 FPS average
• Medium: 33.7 FPS average
• High: 27.4 FPS average
• Ultra: 19.4 FPS average

The 1440p Low result is close to playable but still misses the threshold by over 10 FPS. Every other preset is well below 60 FPS, with Ultra at 19.4 FPS being particularly weak.

At 1920x1080 (1080p), the only playable result appears:

• Low: 73.7 FPS average
• Medium: 50.7 FPS average
• High: 44.7 FPS average
• Ultra: 31.2 FPS average

The Low preset is the only one that clears 60 FPS, and it does so with a comfortable margin. Medium is close at 50.7 FPS, but it fails the playable threshold. High and Ultra are clearly below 60 FPS, with Ultra dropping to 31.2 FPS.

The pattern across all resolutions is consistent: lowering the preset has a significant impact on FPS, and the GPU is the primary driver of these changes. The difference between Low and Ultra at 1080p is 42.5 FPS, which is a 136% improvement for the Low preset. At 1440p, the same comparison shows a 30.1 FPS difference, and at 4K it is 19.7 FPS. The relative impact of settings is largest at 1080p, where the GPU is less overwhelmed and the settings changes have more relative weight.

FAQ

Q: Can this combo run Rust at 60 FPS?

A: Yes, but only at 1920x1080 with the Low preset, where the average FPS is 73.7. At 2560x1440, the best result is 49.5 FPS on Low, and at 3840x2160, the best is 31.7 FPS on Low. No other preset or resolution combination reaches the 60 FPS threshold.

Q: What is the best preset for this combo at 1080p?

A: The Low preset is the only playable option, with an average of 73.7 FPS. The Medium preset averages 50.7 FPS, which is below the 60 FPS threshold, and High and Ultra are progressively lower at 44.7 and 31.2 FPS respectively.

Q: Is the CPU or GPU the limiting factor in this combo?

A: The GPU is the clear bottleneck. The Core i5-14400F ranks in the 83rd percentile among CPUs with strong multi-core and single-core scores, while the RX 580 ranks in the 53rd percentile among GPUs. The large FPS drops when moving from 1080p to 1440p and 4K indicate the GPU is saturated, not the CPU.

Q: How does the RX 580 compare to its nearest rivals in the database?

A: The RX 580 has an average benchmark score of 12928. Its nearest rival is the NVIDIA GeForce RTX 3050 Ti Mobile at 12940, which is 0.1% faster. The GTX 1660 SUPER scores 12986, 0.4% faster. The AMD Radeon 740M scores 12870, 0.5% slower, and the AMD FirePro W5100 scores 12847, 0.6% slower. All are within 1% of each other, meaning similar real-world performance in most games.

Q: How does the Core i5-14400F compare to its nearest rivals?

A: The i5-14400F has an average benchmark score of 32279. Its closest rival is the AMD Ryzen 7 PRO 8840U at 32233, which is 0.1% slower. The Intel Core i9-11900 scores 32226, 0.2% slower. The AMD Ryzen 7 6800HS scores 32354, 0.2% faster, and the Intel Core i7-12800H scores 32121, 0.5% slower. These differences are small enough to be considered negligible.

Q: Is this combo suitable for 1440p gaming in Rust?

A: No. The best 1440p result is 49.5 FPS on Low, which is below the 60 FPS threshold. All other presets at 1440p are below 35 FPS. The verdict in the database lists no playable settings at 2560x1440.

Similar Performance Alternatives

For the CPU, the Core i5-14400F’s nearest rivals in the database are all within 0.5% of its average benchmark score of 32279. The AMD Ryzen 7 PRO 8840U scores 32233, a 0.1% difference, meaning it would behave nearly identically for Rust’s CPU workload. The Intel Core i9-11900 scores 32226, also 0.1% slower. The AMD Ryzen 7 6800HS scores 32354, 0.2% faster, and the Intel Core i7-12800H scores 32121, 0.5% slower. For practical purposes, any of these CPUs would provide the same headroom in Rust, and none would be the limiting factor in this combo.

For the GPU, the RX 580’s nearest rivals are similarly close. The NVIDIA GeForce RTX 3050 Ti Mobile scores 12940, 0.1% higher than the RX 580’s 12928. The NVIDIA GeForce GTX 1660 SUPER scores 12986, 0.4% higher. The AMD Radeon 740M scores 12870, 0.5% lower, and the AMD FirePro W5100 scores 12847, 0.6% lower. These GPUs would produce nearly identical FPS in Rust, meaning a system with any of these cards paired with the i5-14400F would land in the same performance tier. The GTX 1660 SUPER is the fastest of the group, but the margin is too small to change the overall verdict. All of these alternatives would still be limited to 1080p Low for playable Rust performance.

The practical takeaway is that swapping the CPU for any of its nearest rivals would not change the combo’s rank or playability, and swapping the GPU for any of its nearest rivals would also result in the same 1080p Low ceiling. The bottleneck is the GPU tier, not the specific model within that tier.

Best Settings per Resolution

The database’s verdict by resolution is explicit. At 3840x2160, there are no playable settings, meaning no preset achieves an average of 60 FPS or higher. The best result at that resolution is 31.7 FPS on Low, which is not playable. The best settings field is null, and the average FPS at best is also null.

At 2560x1440, the situation is identical: no playable settings. The Low preset averages 49.5 FPS, which is below the 60 FPS threshold. The best settings field is null.

At 1920x1080, there is exactly one playable setting: Low, with an average FPS of 73.7. This is the only resolution and preset combination in the entire dataset that meets the playable threshold. The Medium preset comes close at 50.7 FPS, but it is not enough. For a player using this combo, the recommendation is clear: run Rust at 1920x1080 with the Low preset. This provides a 73.7 FPS average, which is 13.7 FPS above the playable threshold, offering a reasonable margin for dips during busy scenes. The data does not include minimum FPS values, so the actual low points could be lower, but the average is solidly above 60.

For anyone wanting to play at higher resolutions or higher presets, this combo is not suitable. The GPU’s performance ceiling is simply too low for Rust’s demands at 1440p or 4K. The CPU has plenty of headroom, but it cannot compensate for the GPU’s limitations. The recorded data shows that this is a 1080p Low system, and that is the only configuration that delivers playable performance.
