How This Combo Ranks

The Intel Core i5-9400 paired with the Intel Arc B570 ranks 2996 out of 3723 tested combinations in Rust. This places the combo in the lower half of the database, roughly in the 20th percentile of all tested systems. The ranking reflects a pairing that can handle the game at mainstream resolutions, but it is far from a top-tier configuration. The CPU itself sits at the 47th percentile among all tested processors, while the GPU ranks at the 65th percentile among all tested graphics cards. The gap between those two percentile values is telling: the graphics card is notably stronger relative to its peers than the processor is relative to its own peers. In Rust, this imbalance shows up in the measured frame rates, particularly at higher resolutions where the GPU is pushed harder, and at lower resolutions where the CPU becomes the limiting factor.

CPU and GPU Roles

The data shows a clear shift in workload balance depending on resolution and preset. At 1920x1080, the combo delivers 118 FPS on Low settings, 79 FPS on Medium, 67 FPS on High, and 51 FPS on Ultra. The drop from Low to Ultra is roughly 57%, which indicates that the GPU is being increasingly stressed as settings rise. However, the CPU still has enough headroom to keep frame rates above 60 FPS through High settings, and only at Ultra does it fall below that threshold. At 2560x1440, the pattern changes: Low settings produce 81 FPS, but Medium drops to 54 FPS and High to 46 FPS. The scaling from 1080p Low to 1440p Low is a 31% reduction, while from 1080p High to 1440p High is a 31% reduction as well. This consistent percentage drop across settings points to the GPU becoming the dominant factor at 1440p, with the CPU playing a secondary role. At 3840x2160, the GPU is clearly the bottleneck: Low settings yield only 48 FPS, Medium drops to 32 FPS, and High falls to 27 FPS. The resolution scaling from 1440p Low to 4K Low is a 41% reduction, and from 1440p High to 4K High is a 41% reduction as well, confirming that the GPU's rendering load is the primary constraint at 4K. In short, at 1080p the CPU is still relevant, but at 1440p and especially at 4K, the Arc B570's performance dictates the outcome.

Similar Performance Alternatives

Looking at the nearest rivals for the CPU, the Intel Core i5-9400 has an average benchmark score of 2254. The Intel Core i7-1068NG7 scores 2259, which is 0.2% higher, making it essentially identical in compute performance. The Intel Core i7-10710U scores 2248, 0.3% lower, again a negligible difference. The AMD Ryzen 5 PRO 1500 scores 2246, 0.4% lower, and the Intel Core i3-10305 scores 2264, 0.4% higher. In gaming scenarios, any of these processors would deliver frame rates within a couple of percent of the i5-9400, meaning the measured results in Rust would be nearly indistinguishable. For the GPU, the Intel Arc B570 has an average benchmark score of 20556. The NVIDIA GeForce RTX 3070 Mobile scores 20534, 0.1% lower, so it would behave almost identically in Rust. The Intel Arc A750 scores 20582, 0.1% higher, again a negligible difference. The NVIDIA Quadro M4000M scores 20480, 0.4% lower, and the AMD Radeon R9 M390X scores 20662, 0.5% higher. All five GPUs fall within a 0.5% band of each other, so swapping the Arc B570 for any of these would produce frame rates within the margin of measurement error. This means that users with any of these CPU or GPU alternatives should expect very similar Rust performance to the combo analyzed here.

The Verdict

Can this PC run Rust? Yes, but with clear limitations depending on resolution and settings. At 1920x1080, the combo clears the 60 FPS threshold on Low, Medium, and High presets, with the best playable setting being High at 67 FPS average. Ultra falls to 51 FPS, which is below the 60 FPS playability threshold. At 2560x1440, only Low settings reach 81 FPS, which is above 60 FPS; Medium drops to 54 FPS, High to 46 FPS, and Ultra to 35 FPS, all below the threshold. At 3840x2160, no settings achieve 60 FPS: Low produces 48 FPS, Medium 32 FPS, High 27 FPS, and Ultra 21 FPS. In practical terms, this combo is a solid 1080p machine for Rust, a passable 1440p machine only on the lowest preset, and not suitable for 4K gaming at any preset. The data indicates that the GPU is the limiting factor at higher resolutions, while the CPU, though weaker relative to its peers, still manages to keep up at 1080p across most presets.

Measured FPS Breakdown

At 1920x1080, the recorded data shows 118 FPS average on Low settings, with no minimum or maximum values recorded. Medium settings produce 79 FPS average, with a minimum of 67 FPS and a maximum of 91 FPS. High settings yield 67 FPS average, with no minimum or maximum recorded. Ultra settings drop to 51 FPS average, again with no minimum or maximum recorded. The minimum value on Medium (67 FPS) is exactly at the playability threshold, which means even the worst-case frame drops on that preset stay at or above 60 FPS. At 2560x1440, Low settings produce 81 FPS average, with no minimum or maximum recorded. Medium settings yield 54 FPS average, with a minimum of 46 FPS and a maximum of 62 FPS. The minimum of 46 FPS on Medium indicates noticeable dips below the 60 FPS threshold, even though the average is close. High settings produce 46 FPS average, and Ultra settings drop to 35 FPS, both without recorded minimum or maximum values. At 3840x2160, Low settings produce 48 FPS average, Medium settings yield 32 FPS average with a minimum of 27 FPS and a maximum of 37 FPS, High settings produce 27 FPS average, and Ultra settings drop to 21 FPS average. The Medium preset at 4K shows a very tight frame range, with the maximum (37 FPS) still far below the 60 FPS threshold.

FAQ

Q: Is 4K gaming possible with this combo?

A: No. At 3840x2160, even Low settings only reach 48 FPS, and all other presets are significantly lower, so no preset meets the 60 FPS threshold.

Q: How does the CPU compare to its nearest rivals?

A: The Intel Core i5-9400 has an average benchmark score of 2254. The closest rival, the Intel Core i7-1068NG7, scores 2259, which is only 0.2% higher, and the Intel Core i3-10305 scores 2264, 0.4% higher. All rivals are within 0.4% of each other.

Q: How does the GPU compare to its nearest rivals?

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is High, with an average of 67 FPS. Medium also clears the threshold at 79 FPS, and Low reaches 118 FPS, but High offers the best visual quality while maintaining playability. At 2560x1440, the only preset that stays at or above 60 FPS is Low, with an average of 81 FPS. Medium falls to 54 FPS, so Low is the only viable option at this resolution. At 3840x2160, no preset reaches 60 FPS, so there is no best playable setting; the highest average FPS is 48 on Low, but that still falls short of the threshold. For users who must play at 4K, Low settings are the least bad option, but the experience will be below the 60 FPS standard.
