Rust

The Intel Core i5-12400 paired with the Intel Arc B570 presents a mid-range combination that yields highly resolution-dependent results in Rust. The data shows a clear ceiling at 4K, where even the lowest settings struggle to maintain playable frame rates, while 1080p offers a comfortable margin above the 60 FPS threshold for most presets. This analysis breaks down the measured performance, component roles, and practical settings for each resolution.

Measured FPS Breakdown

At 1920x1080, the combination delivers its strongest performance. With Low settings, the average frame rate reaches 118 FPS, providing a large headroom above the 60 FPS target. Medium settings produce an average of 79 FPS, with a minimum of 67 FPS and a maximum of 91 FPS, indicating that even the lower 1% of frames stays above the playable threshold. High settings maintain an average of 67 FPS, which is still above the 60 FPS benchmark, though the lack of reported min/max values suggests a tighter margin. Ultra settings drop the average to 51 FPS, falling below the playable threshold and showing that the most demanding preset is not viable at this resolution.

Moving to 2560x1440, the performance decline is significant but predictable. Low settings deliver an average of 81 FPS, which is the only preset at this resolution that clears the 60 FPS mark. Medium settings average 54 FPS, with a minimum of 46 FPS and a maximum of 62 FPS; the min value indicates that frame drops will be noticeable during intense scenes. High settings average 46 FPS, and Ultra settings fall to 35 FPS. The scaling from 1080p to 1440p shows a reduction of roughly 31% on Low settings (from 118 to 81 FPS), but the drop is more pronounced on High settings, where the average falls from 67 to 46 FPS, a 31% reduction as well.

At 3840x2160, the combination is largely out of its depth. Low settings produce an average of 48 FPS, which is below the 60 FPS target. Medium settings average 32 FPS, with a minimum of 27 FPS and a maximum of 37 FPS, indicating severe frame pacing issues. High settings drop to 27 FPS, and Ultra settings bottom out at 21 FPS. None of these presets approach playable performance, and the gap between Low and Medium at 4K is a substantial 16 FPS, showing that even minor graphical increases impose a heavy cost on the GPU.

CPU and GPU Roles

The benchmark results indicate that the Intel Core i5-12400 is not the primary bottleneck in most scenarios, but its influence becomes visible at lower resolutions and settings. The CPU's multi-threaded performance, as measured by a Cinebench R23 multi-core score of 15989, provides sufficient throughput for Rust's simulation and entity logic. At 1080p with Low settings, the average of 118 FPS suggests that the GPU is still able to render frames quickly, but the CPU's single-thread performance, evidenced by a Geekbench single-core score of 1848, may limit the maximum frame rate in less demanding scenes.

The Intel Arc B570's role becomes dominant as resolution increases. This is clear from the scaling between 1080p and 1440p on Low settings: the frame rate drops from 118 to 81 FPS, a reduction of 37 FPS, which is a 31% decrease. This scaling is typical of a GPU-bound workload, as the number of pixels increases by 78% (from 2.07 million to 3.69 million), yet the frame rate does not drop proportionally, suggesting that other factors like memory bandwidth and shading throughput moderate the impact. The GPU's 10 GB of GDDR6 memory with a 380.0 GB/s bandwidth is sufficient for 1440p, but at 4K, the pixel count quadruples relative to 1080p, and the GPU's 11.52 TFLOPS FP32 compute is insufficient to maintain frame rates above 48 FPS even on Low settings.

Preset scaling further clarifies the component roles. At 1440p, moving from Low to Medium reduces the average from 81 to 54 FPS, a 33% drop. This indicates that the GPU's shading units and texture units (144 TMUs and 80 ROPs) are heavily taxed by increased draw calls and post-processing. At 1080p, the same preset change reduces the average from 118 to 79 FPS, a 33% drop as well, but the absolute frame rates remain higher, showing that the CPU has more headroom to feed the GPU at lower resolutions. The data suggests that the CPU is adequate for 1080p and 1440p, but the GPU's raw throughput is the limiting factor at 4K and with high presets.

Best Settings per Resolution

For 1920x1080, the best settings that remain at or above 60 FPS are High, which achieves an average of 67 FPS. This is the most demanding preset that clears the playable threshold, and it provides a 6 FPS margin above the 60 FPS target. Medium settings offer a safer margin with 79 FPS average, but High is the recommended choice for visual fidelity while maintaining playability.

At 2560x1440, only Low settings achieve the 60 FPS target, with an average of 81 FPS. This preset provides a 21 FPS margin, which is comfortable for most gameplay, but it requires a significant reduction in visual quality. Medium settings fall short at 54 FPS, so Low is the only viable option for a smooth experience at this resolution.

For 3840x2160, no preset reaches 60 FPS. The best performing setting is Low, with an average of 48 FPS, which is still 12 FPS below the playable threshold. Given the data, 4K gaming with this combination is not recommended for Rust, as even the lowest settings cannot maintain a consistent frame rate above 60 FPS.

Similar Performance Alternatives

Looking at the CPU's nearest rivals, the Intel Core i3-14100F has an average benchmark score of 18519, which is 0.9% lower than the i5-12400's score of 18683. This indicates that the i3-14100F would behave nearly identically in Rust, with a negligible performance difference. The AMD EPYC 7643, with an average score of 18697, is 0.1% higher than the i5-12400, meaning it would offer virtually the same frame rates, though its server-oriented design is not a direct consumer alternative. The Intel Core i7-1355U scores 18730, which is 0.3% higher, but its mobile nature would not be a typical pairing. The AMD Ryzen AI 5 330 scores 18811, 0.7% higher, but again, this is a different market segment.

For the GPU, the Intel Arc A750 has an average benchmark score of 20582, which is 0.1% lower than the Arc B570's score of 20556. This means the Arc A750 would deliver almost identical performance in Rust, making it a direct alternative for users considering the B570. The NVIDIA GeForce RTX 3070 Mobile scores 20534, which is 0.1% higher than the B570, indicating comparable performance, though the mobile variant would have different power characteristics. The AMD Radeon R9 M390X scores 20662, 0.5% higher, and the NVIDIA Quadro M4000M scores 20480, 0.4% lower, both showing that the B570 sits in a tight performance band with these older or mobile parts.

How This Combo Ranks

The combination of the Intel Core i5-12400 and Intel Arc B570 ranks 2996 out of 3723 tested combos in Rust. This places it in the lower half of the database, with a percentile position that reflects its performance limitations at higher resolutions. The rank is influenced by the GPU's 65th percentile standing among all GPUs and the CPU's 72nd percentile among all CPUs, but the combination's overall ranking suggests that many other pairings offer better performance in this specific game. The rank of 2996 out of 3723 means that roughly 80% of tested combos outperform this one, which is consistent with the measured FPS results showing that 4K is unplayable and 1440p is limited to Low settings.

The Verdict

Based on the measured data, this PC can run Rust at 1920x1080 with High settings, achieving an average of 67 FPS, which clears the 60 FPS threshold. At 2560x1440, the system is playable only on Low settings, with an average of 81 FPS, providing a stable experience but with reduced visual fidelity. At 3840x2160, the combination fails to reach 60 FPS on any preset, with the best result being 48 FPS on Low settings, which is below the playable threshold. The verdict by resolution is clear: 1080p is fully playable with a good margin, 1440p is playable only with reduced settings, and 4K is not recommended for this game.
