Rust

Measured FPS Breakdown

The recorded data for Rust with the Intel Core i5-10400F and AMD Radeon RX 6800 XT shows a clear performance curve across resolutions and presets. At 1920x1080, the combo delivers 151.9 FPS average on Low settings, 130.1 FPS on Medium, 115.4 FPS on High, and 89.4 FPS on Ultra. Every preset at this resolution clears the 60 FPS playable threshold with substantial headroom, making 1080p a non-issue for this configuration.

Moving to 2560x1440, the averages remain strong but begin to compress. Low settings produce 131.7 FPS, Medium drops to 97.8 FPS, High sits at 81.9 FPS, and Ultra lands at 64.6 FPS. The Ultra preset is the only one that approaches the playable threshold, but it still stays above it. The scaling from 1080p to 1440p costs roughly 13% to 28% of performance depending on preset, with the largest relative drop occurring at Ultra settings.

At 3840x2160, the picture changes significantly. Low settings average 83.8 FPS, Medium falls to 58.8 FPS, High drops to 47.2 FPS, and Ultra bottoms out at 37.2 FPS. The only 4K preset that maintains 60 FPS is Low. Medium misses the threshold by a small margin, while High and Ultra fall well short. The gap between Low and Ultra at 4K is 46.6 FPS, which indicates that the GPU is the dominant constraint at this resolution, with preset selection having a large impact on playability.

The data shows no min or max FPS values recorded for any resolution or preset, so the analysis relies entirely on average FPS. The pattern across all three resolutions is consistent: the performance delta between Low and Ultra grows as resolution increases. At 1080p the spread from Low to Ultra is 62.5 FPS, at 1440p it is 67.1 FPS, and at 4K it reaches 46.6 FPS. This suggests that the CPU can feed the GPU adequately at lower resolutions, but at 4K the GPU workload scales faster than the CPU bottleneck.

Similar Performance Alternatives

The nearest rivals for the Intel Core i5-10400F in the database are closely matched in aggregate benchmark score. The Intel Xeon 6756E scores 14163, just 0.2% lower than the i5-10400F's average of 14185. The Intel Core 7 160UL scores 14232, which is 0.3% higher. The AMD EPYC 7552 scores 14115, 0.5% lower, and the AMD Ryzen 3 7320C scores 14277, 0.6% higher. These deltas are all within one percentage point, meaning any of these CPUs would produce nearly identical frame rates in Rust when paired with the same GPU, assuming the game is not heavily threaded beyond what these parts can deliver.

For the GPU side, the AMD Radeon RX 6800 XT sits at an average benchmark score of 48477. The closest rival is the NVIDIA RTX A1000 Mobile at 47743, which is 1.5% slower. The Intel Arc A550M scores 49737, 2.5% faster. The NVIDIA GeForce RTX 5070 Ti scores 49957, 3% faster, and the AMD Radeon RX Vega 64 also scores 50001, 3% faster. These rivals are all within a narrow band, so swapping the RX 6800 XT for any of them would yield similar Rust performance, with the RTX 5070 Ti and RX Vega 64 offering a slight edge and the RTX A1000 Mobile a slight deficit.

In practical terms, a system built around any of these CPU alternatives would behave almost identically in Rust at the same resolution and settings. The GPU alternatives would shift frame rates by a few percent at most, which translates to roughly 1 to 5 FPS depending on the preset and resolution. The RX 6800 XT's 85th percentile ranking among all GPUs means it sits above most of the field, while the i5-10400F's 68th percentile ranking places it in the upper-middle range for CPUs.

The Verdict

This PC can run Rust, and the verdict depends heavily on the target resolution. At 1920x1080, every preset from Low to Ultra clears the 60 FPS threshold, with Ultra averaging 89.4 FPS. This is a fully playable experience at maximum settings with room to spare. At 2560x1440, the situation is slightly tighter but still positive: all four presets are playable, with Ultra averaging 64.6 FPS and High at 81.9 FPS. The best settings at 1440p per the database are Ultra, which just barely stays above the playable line.

At 3840x2160, the verdict changes. Only Low settings achieve playable frame rates, averaging 83.8 FPS. Medium falls to 58.8 FPS, which misses the 60 FPS mark by a narrow margin. High and Ultra are not viable for smooth gameplay, averaging 47.2 and 37.2 FPS respectively. For 4K gaming, the user must compromise on visual fidelity and stick to Low settings, or drop to a lower resolution.

The overall judgment is that this combo is a strong 1080p and 1440p machine for Rust, capable of maxing out settings at both resolutions. At 4K, it is playable only at the lowest preset, and even then the experience is not as fluid as at lower resolutions. The 60 FPS threshold is met or exceeded in 9 out of 12 tested configurations.

CPU and GPU Roles

The division of labor between the Intel Core i5-10400F and the AMD Radeon RX 6800 XT shifts across resolutions. At 1920x1080, the performance spread between Low and Ultra is 62.5 FPS, which indicates that the GPU is doing most of the heavy lifting, but the CPU is not holding it back. The i5-10400F, with its 6 cores and 12 threads, provides sufficient throughput to keep the RX 6800 XT fed at this resolution. The fact that Ultra still averages 89.4 FPS suggests that neither component is severely bottlenecked.

At 2560x1440, the spread between Low and Ultra grows to 67.1 FPS, and the average FPS at Ultra drops to 64.6. This indicates that the GPU is becoming more of a limiting factor, as the higher resolution increases the pixel workload without a corresponding increase in CPU demand. The CPU's role diminishes slightly, but it still delivers enough performance to allow the GPU to reach playable frame rates at all presets.

At 3840x2160, the GPU is clearly the dominant constraint. The spread between Low and Ultra is 46.6 FPS, and the Ultra preset averages only 37.2 FPS. The CPU is no longer the bottleneck; the RX 6800 XT simply cannot render Rust at 4K Ultra fast enough to hit 60 FPS. The scaling from 1080p to 4K at the same preset shows this clearly: High settings drop from 115.4 FPS at 1080p to 47.2 FPS at 4K, a 59% reduction. Low settings drop from 151.9 to 83.8 FPS, a 45% reduction. These large drops are characteristic of GPU-bound scenarios.

For users upgrading either component, the data suggests that at 1080p and 1440p, the CPU and GPU are reasonably balanced, but pushing toward 4K requires a stronger GPU. The i5-10400F's 68th percentile ranking among CPUs means it is not a top-tier part, but Rust's performance scaling indicates it is sufficient for this GPU at lower resolutions. At 4K, a GPU upgrade would yield larger gains than a CPU upgrade.

How This Combo Ranks

In the database of tested combinations for Rust, this pairing of Intel Core i5-10400F and AMD Radeon RX 6800 XT ranks 1314 out of 3723 combos. This places it in the 65th percentile of all tested systems, meaning roughly 35% of recorded combinations perform better, while 65% perform worse. The rank reflects the balanced nature of this setup: the GPU is in the 85th percentile among all GPUs, while the CPU sits at the 68th percentile among all CPUs. The combination lands in the upper-middle tier of the overall rankings.

Given the 3723 total combos tested, a rank of 1314 indicates that this system is above average for Rust specifically, but not among the elite configurations. The RX 6800 XT's strong 4K compute capabilities are tempered by the i5-10400F's more modest CPU performance, which likely prevents the combo from climbing higher in the rankings at lower resolutions. At higher resolutions where the GPU dominates, the rank would be more favorable compared to systems with weaker GPUs but stronger CPUs.

The rank also implies that a large number of tested combos deliver higher frame rates, likely featuring newer or higher-tier CPUs paired with similarly powerful GPUs. However, the practical takeaway is that this combo sits comfortably in the playable range for the majority of resolutions and presets, and the rank reflects a system that is well-suited for 1080p and 1440p gaming in Rust without reaching the very top of the performance hierarchy.
