Rust

The Intel Core i5-12400F paired with the Intel Arc B580 presents a mid-range desktop combo that produces markedly different results depending on the resolution you target in Rust. The measured data shows a clear pattern: 1080p is comfortable, 1440p requires a settings compromise, and 4K is not viable for smooth play. The i5-12400F sits at the 73rd percentile among all CPUs with an average benchmark score of 19039, while the Arc B580 ranks at the 68th percentile for GPUs with an average score of 23021. These component-level positions align with the in-game results, where the combo ranks 2806th out of 3723 tested combinations, placing it in the lower-middle portion of the database.

Measured FPS Breakdown

The measured frame rates for Rust reveal a steep performance cliff as resolution increases. At 1920x1080, the combo delivers playable performance across most presets. Low settings produce an average of 132.5 FPS, which is more than double the 60 FPS playability threshold. Medium settings drop to 88.1 FPS average, still comfortably above the threshold. High settings yield 73.6 FPS average, maintaining smooth gameplay. Ultra settings fall to 56.5 FPS average, which is below the 60 FPS target but not by a catastrophic margin. The spread from Low to Ultra at 1080p is 76 FPS, showing that graphical fidelity has a substantial impact on this combo's output.

Moving to 2560x1440, the performance picture changes significantly. Low settings produce 89.1 FPS average, which remains well above the threshold. Medium settings average 59.9 FPS, sitting just barely under the 60 FPS line — a single frame per second short of the playability cutoff. High settings average 54.3 FPS, and Ultra drops to 41.9 FPS. The gap between Low and Ultra at 1440p is 47.2 FPS, a narrower range than at 1080p but with every preset except Low falling short of 60 FPS. This suggests the GPU is becoming the limiting factor as pixel count rises.

At 3840x2160, the combo struggles across the board. Low settings average 56.8 FPS, which is the only preset that comes close to the threshold. Medium settings average 33.7 FPS, High averages 33 FPS, and Ultra averages 25.9 FPS. The difference between Low and Ultra at 4K is 30.9 FPS, indicating that even the lowest settings cannot consistently deliver smooth gameplay. The data shows that the Arc B580's 12 GB of GDDR6 memory and 456.0 GB/s bandwidth are insufficient for the demands of Rust at 4K with this CPU pairing.

The measured data includes only average FPS values; no minimum or maximum frame times were recorded in the fact pack. This means the analysis relies solely on average performance, which can mask occasional stutters or frame spikes. However, the averages themselves provide a clear directional picture: this combo is a 1080p performer with limited 1440p capability and no practical 4K usage.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is High settings, which delivers an average of 73.6 FPS. This leaves a 13.6 FPS margin above the playability threshold, providing some headroom for demanding scenes or background processes. Ultra settings at 1080p fall short at 56.5 FPS, so High represents the best visual quality that maintains smooth performance.

For 2560x1440, the only preset that clears 60 FPS is Low, with an average of 89.1 FPS. This is the best settings option at this resolution, though it comes with a significant visual fidelity reduction. Medium settings at 1440p average 59.9 FPS — technically below the threshold — so Low is the sole playable option. The 29.2 FPS gap between Low and Medium at 1440p shows that stepping up one preset level incurs a heavy performance cost.

At 3840x2160, no preset reaches the 60 FPS threshold. The closest is Low at 56.8 FPS, but that still falls 3.2 FPS short. The verdict data confirms this: the playable settings list for 4K is empty, with no best settings recommendation. Users targeting 4K would need to accept sub-60 FPS performance or look to different hardware entirely.

How This Combo Ranks

The Intel Core i5-12400F and Intel Arc B580 combination ranks 2806th out of 3723 tested combos in Rust, putting it in the bottom quarter of the database. This rank reflects the GPU's mid-tier standing more than the CPU's. The i5-12400F ranks at the 73rd percentile among all CPUs, which is a solid mid-range position, but the Arc B580's 68th percentile GPU ranking drags the overall combo down. The measured FPS data supports this: at 1080p High, the combo achieves 73.6 FPS, which is respectable but not exceptional for a modern setup. The rank suggests that roughly 75% of tested configurations can match or exceed this performance in Rust, likely due to stronger GPUs or more balanced pairings.

The gap between component percentiles and the combo rank highlights how Rust's specific workload interacts with this hardware. The CPU's 6 cores and 12 threads with an 18 MB shared L3 cache handle the game's logic adequately, but the GPU's 13.67 TFLOPS FP32 performance and 192-bit memory bus create a bottleneck at higher resolutions. At 1080p, the i5-12400F's single-thread score of 909 in 3DMark and 1680 in Cinebench R23 keep the pipeline fed. At 1440p and above, the Arc B580's pixel rate of 213.6 GPixel/s and texture rate of 427.2 GTexel/s become limiting factors.

Similar Performance Alternatives

Looking at the nearest rivals for both components provides context for what else would behave similarly in Rust. For the CPU, the AMD Ryzen 5 7535HS matches the i5-12400F almost exactly with an average score of 19047 versus 19039 (0% delta). The Intel Core 3 201E (19056, -0.1%) and Intel Core i5-1335U (18982, 0.3%) are also within a rounding error of identical performance. Any of these CPUs would produce nearly the same frame rates in Rust when paired with the same GPU, since the differences are statistically negligible.

For the GPU, the AMD Radeon RX 580 2048SP (23061, -0.2%), NVIDIA GeForce RTX 2080 (22895, 0.6%), and NVIDIA GeForce RTX 3080 (23172, -0.7%) all sit within 1% of the Arc B580's average score of 23021. This means swapping the Arc B580 for any of these cards would yield essentially the same measured FPS in Rust. The RTX 3080 being this close is surprising given its higher tier in NVIDIA's lineup, but the benchmark data shows aggregate performance parity. The RTX 2080 being slightly slower than the Arc B580 suggests that the Arc card holds its own against older high-end options.

A system with the i5-12400F and any of these rival GPUs would likely produce FPS numbers within a few frames of the measured values at each resolution and preset. The same applies to a build with the Ryzen 5 7535HS and the Arc B580. This data indicates that users seeking similar Rust performance could consider these alternatives without expecting meaningful differences.

The Verdict

The data shows that this PC can run Rust, but the playable experience depends heavily on the target resolution. At 1920x1080, the combo clears the 60 FPS threshold on High, Low, and Medium settings, with High being the best visual option at 73.6 FPS average. This is a fully playable configuration for most users. At 2560x1440, only Low settings reach 89.1 FPS average, while Medium falls just short at 59.9 FPS — a frustratingly narrow miss. Users at 1440p must accept Low settings to maintain smooth performance. At 3840x2160, no preset reaches 60 FPS; the best case is Low at 56.8 FPS, which still falls below the threshold. The verdict is clear: this combo is a solid 1080p gaming setup, a marginal 1440p option with reduced visuals, and not suitable for 4K play. Given the i5-12400F's strong CPU performance and the Arc B580's mid-tier GPU capabilities, the bottleneck at higher resolutions is the graphics card, not the processor.
