Rust

The AMD Ryzen 5 8400F and Intel Arc B570 combination delivers playable performance in Rust only up to 1440p with the lowest settings, while 1080p opens up a wider range of presets. Benchmark data shows the pair reaches a 60 FPS target at 1080p on High settings, but the demanding survival title quickly overwhelms the system at higher resolutions and quality levels. The measured results place this combo at rank 2996 out of 3723 tested configurations, indicating a mid-to-low position in the overall performance hierarchy for Rust.

Measured FPS Breakdown

At 3840x2160, the system struggles across all tested presets. The Low preset averages 48 FPS, which is the only 4K result above 40 FPS. Medium drops to 32 FPS average with a range of 27 to 37 FPS. High falls further to 27 FPS, while Ultra bottoms out at 21 FPS. None of these figures approach the 60 FPS threshold, and the gap between Low and Ultra represents a 27 FPS spread, showing that even the most aggressive quality reduction cannot salvage playable 4K performance.

Moving to 2560x1440, the picture improves substantially. Low settings produce an average of 81 FPS, comfortably exceeding the playable threshold. Medium averages 54 FPS with a 46 to 62 FPS range, sitting just below the 60 FPS mark but with occasional dips and peaks that straddle it. High averages 46 FPS, and Ultra drops to 35 FPS. The scaling from Low to Ultra shows a 46 FPS difference, indicating that resolution and settings interact heavily with the Arc B570’s capabilities.

At 1920x1080, performance becomes genuinely playable on multiple presets. Low leads with 118 FPS average, a strong result for competitive play. Medium follows at 79 FPS with a 67 to 91 FPS range. High reaches 67 FPS, clearing the 60 FPS bar with a modest margin. Ultra falls to 51 FPS, missing the target. The progression from Low to Ultra spans 67 FPS, and the Medium preset’s minimum of 67 FPS shows consistent frame delivery even during demanding scenes.

Best Settings per Resolution

At 3840x2160, no tested preset achieves 60 FPS. The best available option is Low with an average of 48 FPS, but this still falls short of the playable threshold. Users targeting 4K must accept sub-60 FPS performance or reduce resolution.

For 2560x1440, the only preset that stays at or above 60 FPS is Low, delivering 81 FPS average. Medium comes close at 54 FPS but cannot sustain the target consistently. Low is the clear choice for 1440p playability, providing a healthy margin above the threshold while maintaining a responsive experience.

At 1920x1080, the most demanding preset that stays at or above 60 FPS is High, with a 67 FPS average. Medium offers more headroom at 79 FPS, and Low reaches 118 FPS for maximum fluidity. High represents the sweet spot for visual quality versus performance, as Ultra’s 51 FPS average falls below the target. The data indicates that 1080p High is the recommended balance for this hardware.

CPU and GPU Roles

The performance scaling across resolutions reveals how the workload shifts between the Ryzen 5 8400F and Arc B570. At 1080p, the CPU’s six Zen 4 cores with 12 threads handle the game’s simulation and physics demands relatively well. The Ryzen 5 8400F scores 20,851 in Cinebench R23 multi-core and 2,943 in single-core, placing it in the 77th percentile of all CPUs. This strong single-threaded capability supports the 118 FPS Low result, where the GPU is not the primary bottleneck.

As resolution increases to 1440p and 4K, the Arc B570 becomes the limiting factor. The GPU’s 10 GB GDDR6 memory on a 160-bit bus with 380 GB/s bandwidth is tested heavily by Rust’s large open-world environments. At 4K, the average FPS drops by roughly 40-50% compared to 1080p across matching presets, indicating GPU-bound behavior. For example, High settings fall from 67 FPS at 1080p to 46 FPS at 1440p, then to 27 FPS at 4K — a consistent degradation that points to pixel throughput limitations.

The CPU’s role is more prominent at lower resolutions and lower settings. At 1080p Low, the 118 FPS result suggests the Ryzen 5 8400F’s boost clock of 4.70 GHz and 16 MB shared L3 cache are sufficient to feed the GPU. The 3DMark single-thread score of 951 and passmark single-thread score of 3,685 indicate solid IPC, which matters for Rust’s server-side and entity-tick logic. However, the CPU’s percentile rank of 77 against all CPUs means it is not a top-tier part, and at 4K the GPU’s 65th percentile ranking becomes the dominant constraint.

The scaling between presets also highlights this split. At 1080p, moving from Low to Ultra costs 67 FPS, with the GPU handling the extra shading load. At 4K, the same settings change costs only 27 FPS, showing that the GPU is already saturated and additional settings have diminishing returns. The Arc B570’s 11.52 TFLOPS FP32 throughput and 360 GTexel/s texture rate are respectable for 1080p but insufficient for 4K Ultra in a game like Rust.

FAQ

Q: Can this PC run Rust at 60 FPS in 1080p?

A: Yes, at High settings the average FPS is 67, which clears the 60 FPS threshold. Medium and Low also exceed it with 79 FPS and 118 FPS respectively. Ultra, however, drops to 51 FPS and is not playable at 60 FPS.

Q: What is the best preset for 1440p gaming?

A: Low is the only preset that maintains 60 FPS, averaging 81 FPS. Medium averages 54 FPS, which is below the threshold, and High and Ultra are further behind at 46 FPS and 35 FPS.

Q: Is 4K gaming possible with this hardware?

A: No, the highest average FPS at 3840x2160 is 48 on Low settings. Medium, High, and Ultra all fall below 32 FPS, making 4K unplayable at the 60 FPS target.

Q: How does the Ryzen 5 8400F compare to similar CPUs for this game?

A: The Ryzen 5 8400F has an average benchmark score of 25,005, which is 0.2% higher than the AMD Ryzen 5 7500F and 0.3% higher than the Intel Core i7-11850H. It trails the AMD EPYC 9474F by 0.4%, but that is a server part not relevant for gaming.

Q: What is the frame time consistency at 1080p Medium?

A: The average FPS is 79 with a minimum of 67 and a maximum of 91. This tight range indicates stable frame delivery, with the minimum still above the 60 FPS target.

Q: Does the Arc B570 outperform its nearest GPU rival?

A: The Arc B570’s average benchmark score is 20,556, which is 0.1% higher than the NVIDIA GeForce RTX 3070 Mobile and 0.4% higher than the NVIDIA Quadro M4000M. It is 0.1% lower than the Intel Arc A750 and 0.5% lower than the AMD Radeon R9 M390X.

Similar Performance Alternatives

For the CPU, the nearest rival is the AMD Ryzen 5 7500F, with an average score of 24,964 versus the 8400F’s 25,005 — a negligible 0.2% difference. This means games like Rust will perform nearly identically with either processor. The Intel Core i7-11850H and Intel Core i7-13620H are also close, with scores of 24,935 and 24,911 respectively, differing by 0.3% and 0.4%. The AMD EPYC 9474F scores 25,103, which is 0.4% higher, but its server orientation makes it an impractical alternative for a gaming PC.

On the GPU side, the Intel Arc A750 is the closest competitor, scoring 20,582 versus the B570’s 20,556 — a 0.1% gap. Users could expect nearly identical frame rates in Rust with either card. The NVIDIA GeForce RTX 3070 Mobile scores 20,534, just 0.1% lower, and would deliver similar performance in this title. The NVIDIA Quadro M4000M and AMD Radeon R9 M390X are also within 0.5% of the B570’s score, though these are older or workstation-oriented parts that may lack modern feature support.

Combining these, a system with a Ryzen 5 7500F and an Arc A750 would behave almost exactly like the tested configuration. The 1080p High result of 67 FPS would likely replicate within a few frames, and the 1440p Low limit of 81 FPS would hold as well. These alternatives offer no meaningful performance advantage or disadvantage for Rust.

The Verdict

This PC can run Rust at 60 FPS, but with clear limits. At 1920x1080, the system achieves playable performance on High, Medium, and Low presets, with High being the most demanding option that stays above the threshold at 67 FPS. Ultra falls short at 51 FPS. At 2560x1440, only Low is playable, delivering 81 FPS average. All other presets at 1440p miss the 60 FPS target. At 3840x2160, no preset reaches 60 FPS, with the best result being 48 FPS on Low.

The verdict is straightforward: this hardware is a solid 1080p gaming setup for Rust, capable of handling high-quality settings with smooth frame rates. It can stretch to 1440p only on the lowest settings, which sacrifices visual fidelity for playability. 4K is not viable for this title with the Ryzen 5 8400F and Arc B570 combination. The data confirms that Rust’s demanding nature requires more GPU headroom for higher resolutions, while the CPU remains sufficient for 1080p play. Users seeking 1440p or 4K experiences should look to stronger graphics hardware.
