Rust

The Intel Core i5-9400 paired with the Intel Arc B580 is a combination that lands in the lower-mid tier of tested configurations for Rust, holding the 1337th spot out of 1717 combos. The data indicates a system that is heavily reliant on the graphics card to carry frame rates, with the six-core processor providing just enough support to avoid becoming a severe bottleneck at lower resolutions. This analysis breaks down the measured performance across all settings and resolutions to help determine where this combo excels and where it falls short.

FAQ

Q: What is the best resolution to play Rust with this hardware?

A: Based on the measured FPS data, 1920x1080 is the only resolution where this combo consistently delivers playable frame rates across all settings. At this resolution, the average FPS ranges from 56.2 at Ultra to 130.5 at Low, with Medium and High hitting 88.7 and 74.8 respectively.

Q: How does this combo compare to other tested configurations?

A: The combo ranks 1337th out of 1717 tested combinations, placing it in the 22nd percentile overall. This means roughly 78% of tested combos perform better in Rust, but it still outperforms the bottom 22% of configurations.

Q: Is the Intel Core i5-9400 holding back the Intel Arc B580?

A: The CPU's benchmark scores indicate it is a mid-range processor, sitting at the 50th percentile among all CPUs. With 6 cores and 6 threads boosting to 4.10 GHz, it provides adequate single-thread performance for Rust, but the data suggests the GPU is the primary driver of frame rates.

Q: What graphics settings should be avoided at 4K?

A: At 3840x2160, the Ultra preset delivers only 23.1 average FPS, and High is not much better at 31.3. These are below the generally accepted threshold for smooth gameplay, so they should be avoided in favor of Medium or Low settings.

Q: How much faster is the Low preset compared to Ultra at 1080p?

A: The difference is substantial. At 1920x1080, the Low preset achieves an average of 130.5 FPS, which is 74.3 FPS higher than the Ultra preset's 56.2 FPS. This represents a 132% performance uplift.

Q: Does the GPU have enough memory for Rust at high resolutions?

A: The Intel Arc B580 comes with 12 GB of GDDR6 memory on a 192-bit bus. The measured data shows playable performance at 2560x1440 on Medium settings (59.2 FPS), but 4K performance is limited, suggesting the memory bandwidth of 456.0 GB/s is sufficient for the game's demands at lower resolutions.

GPU Role

The Intel Arc B580 is the dominant component in this pairing, and its architecture is built around a 5 nm process with 2560 shading units. The GPU's high boost clock of 2670 MHz directly influences the frame rates seen in the measured data. The 12 GB of GDDR6 memory is a notable asset, as Rust is a game that can consume significant video memory, especially at higher resolutions and detail levels. The memory runs at an effective speed of 19 Gbps, delivering a bandwidth of 456.0 GB/s, which helps the card handle texture streaming in the game's large, open-world environments.

The performance scaling across settings shows the GPU's raw power. At 1920x1080, the jump from Low (130.5 FPS) to Ultra (56.2 FPS) is a 74.3 FPS drop, a 132% reduction, which is a steep price for the visual fidelity gains. This pattern is consistent at 2560x1440, where the frame rate falls from 89.8 FPS on Low to 41.9 FPS on Ultra. At 3840x2160, the GPU is clearly taxed, with even the Medium preset only managing 34.8 FPS. The data shows that the Arc B580 is capable of high refresh rates at 1080p but needs settings reduced to maintain playability as resolution increases.

How This Combo Ranks

The combo's position of 1337 out of 1717 tested combinations is a clear indicator of its standing in the benchmark database. This rank is not surprising given the components involved. The Intel Core i5-9400 is a 6-core, 6-thread processor from the Coffee Lake architecture, which is now considered an older generation. Its benchmark scores place it at the 50th percentile, with an average score of 2305. Its nearest rivals include the Intel Core i3-10305 (0.2% faster) and the Intel Core i7-8809G (0.6% slower), showing it is in a crowded field of mid-range processors.

The Intel Arc B580, in contrast, is a more modern part. Its average benchmark score of 23021 places it at the 66th percentile among all GPUs. Its nearest rival is the NVIDIA GeForce RTX 4060, which is 0.7% faster, and the AMD Radeon 760M, which is 0.1% faster. This shows the GPU is a solid mid-range performer. The combination of a 50th-percentile CPU and a 66th-percentile GPU results in a system that is less than the sum of its parts, ranking in the 22nd percentile of combos. The data suggests that the CPU and GPU pairing is not optimal for Rust, likely due to the CPU's limited thread count struggling with the game's simulation overhead in certain scenarios.

Settings Recommendations

For a balanced experience, the Medium preset is the recommended starting point. At 1920x1080, this yields an average of 88.7 FPS, which is smooth for most players. At 2560x1440, the Medium preset drops to 59.2 FPS, which is still playable but borders on the edge of what is acceptable for fast-paced action. The data shows a clear trend: the High preset offers diminishing returns for a significant frame rate hit. At 1080p, High is 74.8 FPS, which is 13.9 FPS slower than Medium.

The Low preset is the best choice for competitive play or for pushing high refresh rate monitors. It delivers 130.5 FPS at 1080p and 89.8 FPS at 1440p, which are excellent numbers for Rust. However, the visual quality will be noticeably reduced. For 4K gaming, the Low preset is the only viable option, achieving 57 FPS, while Medium and High fall below 35 FPS. The Ultra preset should be avoided at all resolutions with this combo, as it only manages 56.2 FPS at 1080p and drops to an unplayable 23.1 FPS at 4K.

Measured FPS Breakdown

At 1920x1080, the performance is strong. The Low preset averages 130.5 FPS, which is the highest score across all tests. Medium follows with 88.7 FPS, High with 74.8 FPS, and Ultra with 56.2 FPS. The gap between Low and Ultra is 74.3 FPS, showing a steep performance curve.

At 2560x1440, frame rates take a noticeable hit. The Low preset averages 89.8 FPS, which is still excellent. Medium drops to 59.2 FPS, and High to 50.9 FPS. Ultra falls to 41.9 FPS, which is borderline playable for slower gameplay but not ideal for competitive scenarios.

At 3840x2160, the GPU is overwhelmed. The Low preset manages 57 FPS, which is the only playable option at this resolution. Medium drops to 34.8 FPS, High to 31.3 FPS, and Ultra to 23.1 FPS. These scores indicate that 4K gaming is only feasible with the lowest settings.

CPU Role

The Intel Core i5-9400 is a 6-core, 6-thread processor based on the Coffee Lake architecture, manufactured on a 14 nm process. It has a base clock of 2.90 GHz and a boost clock of 4.10 GHz. The CPU's benchmark results show a Cinebench R23 multi-core score of 7969 and a single-core score of 1125. These scores place it at the 50th percentile of all CPUs, indicating it is an average performer.

In Rust, the CPU's role is crucial for handling the game's simulation, including physics, entity updates, and server-side calculations. The 6 threads are sufficient for most tasks, but the data suggests they can become a limiting factor. The combo's low rank of 1337 out of 1717 is partly attributable to this CPU. While the GPU is capable of high frame rates, the CPU may not be able to feed it enough data in complex scenes, leading to stutters or frame drops that are not captured in the average FPS numbers. The 9 MB of shared L3 cache helps with data locality, but the lack of hyper-threading means the processor has to work harder to manage multiple tasks simultaneously. The memory bandwidth of 42.7 GB/s via dual-channel DDR4 is standard for the platform but is far lower than the GPU's 456.0 GB/s, which can lead to data transfer bottlenecks in certain scenarios.
