FAQ

Q: Can this PC run Rust at 60 FPS?

A: Yes, but only at 1920x1080 with Low settings. The measured average FPS at that resolution and preset is 76, which clears the 60 FPS playable threshold. At 2560x1440 and 3840x2160, no preset reaches 60 FPS.

Q: What average FPS does this combo achieve at 1080p?

A: At 1920x1080, the average FPS ranges from 33 on Ultra to 76 on Low. Medium averages 51 FPS with a minimum of 44 and a maximum of 59, while High averages 43 FPS.

Q: Is the Intel Arc B390 a strong GPU for this game?

A: No. The GPU sits at the 9th percentile among all tested GPUs, and its nearest rivals include the NVIDIA GeForce GT 710 and GT 625 OEM. Its single recorded benchmark score is 1482 in 3DMark Steel Nomad DX12, which is very low.

Q: How does the Intel Core i5-10400F compare to nearby CPUs?

A: The CPU is at the 68th percentile among all tested CPUs. Its average benchmark score is 14185, which is within 0.6% of the AMD Ryzen 3 7320C (14277), Intel Core 7 160UL (14232), Intel Xeon 6756E (14163), and AMD EPYC 7552 (14115).

Q: What are the minimum FPS values at 1440p Medium?

A: At 2560x1440 with Medium settings, the minimum FPS is 30, the maximum is 41, and the average is 35. This is far below the 60 FPS threshold.

Q: Is the i5-10400F or the Arc B390 the limiting factor in Rust?

A: The data indicates the GPU is the primary bottleneck. The CPU has strong multi-threaded scores (Cinebench R23 multi-core at 10283, PassMark multi-thread at 12115), while the GPU ranks in the bottom 10% of all GPUs. At higher resolutions, FPS drops significantly, which points to GPU-bound rendering.

How This Combo Ranks

The Intel Core i5-10400F paired with the Intel Arc B390 ranks 3312 out of 3723 tested combos in Rust. This places the system in the bottom 11% of all configurations tested in the database. The ranking reflects the severe GPU limitation: the Arc B390 is an integrated graphics solution with a 9th percentile score among all GPUs, while the CPU is a mid-range desktop part at the 68th percentile.

The gap between the CPU's relative strength and the GPU's weakness is stark. The i5-10400F delivers a Cinebench R23 multi-core score of 10283 and a PassMark multi-thread score of 12115, both respectable for a 6-core, 12-thread Comet Lake processor. The Arc B390, by contrast, produces just 1482 in 3DMark Steel Nomad DX12, placing it alongside GPUs like the GeForce GT 710 and GT 625 OEM. This combination means the system's overall ranking is dragged down almost entirely by the GPU.

In practical terms, the combo sits within the bottom 400 configurations tested for Rust. The CPU is not the issue; it has enough compute headroom for this game based on its synthetic benchmark results. The GPU simply cannot sustain playable frame rates at most settings and resolutions. The ranking would likely improve substantially with a discrete GPU, even a modest one, because the CPU has demonstrated it can handle multi-threaded workloads well.

Measured FPS Breakdown

The measured FPS data covers three resolutions and four settings presets each. All numbers below are from the database's recorded measurements.

3840x2160 (4K):

• Low: 31 average FPS (min and max not recorded)
• Medium: 21 average FPS, with a minimum of 18 and a maximum of 24
• High: 18 average FPS (min and max not recorded)
• Ultra: 13 average FPS (min and max not recorded)

At 4K, the system never approaches the 60 FPS threshold. Even on Low, the average of 31 FPS is roughly half of what is needed for smooth gameplay. The step from Low to Medium costs about 10 FPS, and High and Ultra drop further to 18 and 13 FPS respectively.

2560x1440 (1440p):

• Low: 53 average FPS (min and max not recorded)
• Medium: 35 average FPS, with a minimum of 30 and a maximum of 41
• High: 30 average FPS (min and max not recorded)
• Ultra: 23 average FPS (min and max not recorded)

At 1440p, Low is the only preset that comes close to 60 FPS, but it still falls short at 53 FPS. Medium drops to 35 FPS, and the minimum of 30 FPS indicates noticeable stutter in demanding scenes. High and Ultra are well below playable levels.

1920x1080 (1080p):

• Low: 76 average FPS (min and max not recorded)
• Medium: 51 average FPS, with a minimum of 44 and a maximum of 59
• High: 43 average FPS (min and max not recorded)
• Ultra: 33 average FPS (min and max not recorded)

At 1080p, Low is the only preset that clears the 60 FPS threshold, with a 76 FPS average. Medium comes close at 51 FPS but the maximum of 59 FPS means it never reaches 60. High and Ultra are significantly lower at 43 and 33 FPS.

The scaling pattern is consistent across resolutions: each step up in settings costs roughly 15-20% performance, and each resolution increase costs a similar amount. The data shows the GPU is overwhelmed at anything above 1080p Low.

The Verdict

Can this PC run Rust? The answer depends on the resolution and settings, but the verdict is clear: at 1920x1080 with Low settings, the system averages 76 FPS, which is above the 60 FPS playable threshold. This is the only configuration that qualifies as playable.

At 2560x1440, no preset reaches 60 FPS. The best option is Low at 53 FPS, which is close but still below the threshold. Medium, High, and Ultra all fall well short at 35, 30, and 23 FPS respectively.

At 3840x2160, the situation is worse. Low averages 31 FPS, Medium 21 FPS, High 18 FPS, and Ultra 13 FPS. None of these are remotely playable for a fast-paced survival game like Rust.

The verdict by resolution is straightforward: playable only at 1080p Low. If the user is willing to accept frame rates below 60 FPS, 1440p Low at 53 FPS might be tolerable, but the database's playable threshold is set at 60 FPS, and this combo does not meet it at that resolution.

CPU and GPU Roles

The data reveals a clear division of labor between the CPU and GPU in Rust. The i5-10400F is a capable mid-range processor with a PassMark multi-thread score of 12115 and a Cinebench R23 multi-core score of 10283. Its single-thread performance is also solid, with a Geekbench single-core score of 1420 and a PassMark single-thread score of 2541. For a survival game that relies on physics, entity updates, and world simulation, this CPU has enough headroom.

The bottleneck is the Arc B390. Its 9th percentile ranking among all GPUs and its nearest rivals (GeForce GT 710, GT 625 OEM, GT 520MX) indicate it is in entry-level integrated territory. The scaling between resolutions confirms this: going from 1080p Low (76 FPS) to 1440p Low (53 FPS) is a 30% drop, and going to 4K Low (31 FPS) is a further 42% drop. This pattern is characteristic of a GPU that runs out of pixel throughput and memory bandwidth at higher resolutions.

The Arc B390 has only 1536 shading units, 48 texture mapping units, and 24 ROPs, with a boost clock of 2500 MHz and a pixel rate of 60 GPixel/s. These specifications are far below what modern discrete GPUs offer. The GPU's FP32 throughput of 7.680 TFLOPS is modest, and its memory is system-shared, which adds latency and bandwidth constraints in a game like Rust that streams large world data.

At 1080p, the CPU has more influence because the GPU is less stressed. The jump from Low (76 FPS) to Medium (51 FPS) at 1080p is 25 FPS, which is a significant setting-dependent penalty. At 1440p, the same Low-to-Medium jump costs 18 FPS, and at 4K it costs 10 FPS. This diminishing gap shows that as resolution increases, the GPU becomes the dominant factor and the CPU's role recedes.

Best Settings per Resolution

Based on the 60 FPS playable threshold, the best settings are determined by the most demanding preset that still maintains at least 60 FPS average.

1920x1080: Low is the only playable preset, with an average of 76 FPS. Medium falls below the threshold at 51 FPS, so Low is the highest playable setting. The database confirms this as the best settings with an average FPS of 76.

2560x1440: No preset reaches 60 FPS. The closest is Low at 53 FPS, which is below the threshold. There are no playable settings at this resolution.

3840x2160: No preset reaches 60 FPS. The best option is Low at 31 FPS, which is far below the threshold. There are no playable settings at this resolution.

For users who prioritize frame rate over visual fidelity, 1080p Low is the only viable configuration. The 76 FPS average provides some headroom above the 60 FPS threshold, which may help during intense moments with multiple players or large structures.

Similar Performance Alternatives

The nearest rivals for the CPU and GPU provide context for what other hardware would behave similarly in this combination.

CPU Rivals: The Intel Core i5-10400F has an average benchmark score of 14185. Its nearest rivals are:

• Intel Core 7 160UL: average score 14232, which is 0.3% higher
• AMD Ryzen 3 7320C: average score 14277, which is 0.6% higher
• Intel Xeon 6756E: average score 14163, which is 0.2% lower
• AMD EPYC 7552: average score 14115, which is 0.5% lower

These deltas are all within a fraction of a percent, meaning any of these CPUs would perform nearly identically in Rust when paired with the same GPU. The Xeon 6756E and EPYC 7552 are server parts, but their compute characteristics are close enough that frame rates would not change meaningfully. The Ryzen 3 7320C and Core 7 160UL are lower-power parts, but they still match the i5-10400F's overall score.

GPU Rivals: The Intel Arc B390 has an average benchmark score of 1482. Its nearest rivals are:

• NVIDIA GeForce GT 520MX: average score 1463, which is 1.3% lower
• NVIDIA GeForce 800M: average score 1460, which is 1.5% lower
• NVIDIA GeForce GT 625 OEM: average score 1446, which is 2.5% lower
• NVIDIA GeForce GT 710: average score 1443, which is 2.7% lower

These GPUs are all within 3% of the Arc B390's score, so swapping to any of them would produce nearly identical FPS in Rust. The GT 520MX and GT 710 are older discrete GPUs, while the 800M is a mobile part. The data suggests that none of these alternatives would improve the playability situation: they all sit at the same low performance tier.

If a user were to pair the i5-10400F with a significantly stronger GPU, the CPU would likely not be the limiting factor based on its percentile ranking. However, the database only records the tested combination, so no such extrapolation is made here.
