Rust

The Intel Core i5-14400F paired with the AMD Radeon RX 570 produces a benchmark profile in Rust that is heavily constrained by the graphics card, particularly at higher resolutions and settings. The measured data reveals a system that can achieve playable frame rates only under specific, reduced configurations, while struggling significantly under load at 4K. This analysis breaks down the measured performance metrics to identify the bottlenecks and provide actionable settings guidance.

Resolution Scaling

The frame rate drop from 1080p to 4K is severe, indicating a profound GPU limitation at higher resolutions. At Low settings, the average frame rate falls from 64.3 FPS at 1920x1080 to 45.6 FPS at 2560x1440, a reduction of approximately 29%. Moving from 1440p to 4K at Low settings, the average drops further to 25.7 FPS, representing another 44% decrease. This steep scaling curve demonstrates that the RX 570’s rendering throughput is quickly overwhelmed as pixel count increases.

The trend is even more pronounced at higher graphical presets. At High settings, the average frame rate plummets from 39.6 FPS at 1080p to 25 FPS at 1440p (a 37% drop) and then to 14.7 FPS at 4K (a further 41% drop). This pattern confirms that the GPU is the primary limiting component in this configuration. The data suggests that the RX 570 simply lacks the fill rate and processing power to maintain fluid performance beyond 1080p, with the 4K results being largely unplayable across all settings.

The scaling between Medium and High at the same resolution is also telling. At 1080p, the difference between Low (64.3 FPS) and Medium (45 FPS) is a 30% performance penalty, while the jump from Medium to High (39.6 FPS) is a further 12% reduction. This indicates that even modest increases in graphical fidelity have a substantial impact on the GPU, reinforcing that the processor is not the limiting factor in these scenarios.

GPU Role

The AMD Radeon RX 570 is the clear performance bottleneck in this configuration. Its specifications—4 GB of GDDR5 memory on a 256-bit bus with 224.0 GB/s bandwidth—are modest by modern standards. The GPU’s 5.095 TFLOPS of FP32 compute and 32 ROPs are insufficient for the demanding rendering load of Rust at higher resolutions. This is reflected in the benchmark scores, where the GPU sits in the 74th percentile of all GPUs, with an average benchmark score of 30158.

The GPU’s nearest rivals in the database, including the NVIDIA GeForce RTX 5060 and AMD Radeon RX 7700 XT, show deltaPct values of 0.2% or less, meaning their average benchmark scores are nearly identical. This places the RX 570 in a performance tier that is contemporary with much newer cards, but the measured FPS data in Rust tells a more nuanced story. The 4 GB VRAM capacity is likely a limiting factor at 4K with High or Ultra settings, where texture and geometry data can exceed this allocation, leading to severe frame rate degradation.

The data shows that the GPU’s performance scales poorly with resolution. At 1080p Low, the card delivers 64.3 FPS, which is a playable result. However, the Ultra preset at 1080p yields only 29.4 FPS, and the 4K Ultra result of 13.6 FPS is effectively a slideshow. This pattern suggests that the RX 570’s architectural limits, including its 14 nm process node and GCN 4.0 design, prevent it from handling the increased shader complexity and memory pressure of higher settings.

Settings Recommendations

Based on the measured FPS rows, the optimal balance between visual quality and playability is achieved at 1080p with the Low preset. This configuration produces an average frame rate of 64.3 FPS, which is suitable for the fast-paced, competitive nature of Rust’s survival gameplay. The Medium preset at 1080p, with an average of 45 FPS, is also a viable option for users who prioritize visual fidelity over maximum smoothness.

At 1440p, the data suggests that only the Low preset (45.6 FPS) approaches playability. The Medium preset at 1440p drops to 33.5 FPS, which may be acceptable for less demanding scenarios, but High (25 FPS) and Ultra (17.9 FPS) are not recommended for active gameplay. For 4K, none of the presets provide a playable experience, with the highest average being 25.7 FPS at Low settings. Users with this combo should avoid 4K entirely unless they are willing to tolerate severe stuttering.

The data indicates that the RX 570’s performance is best utilized at 1080p, where the CPU’s capabilities can be more fully leveraged. The Ultra preset at 1080p (29.4 FPS) is a poor trade-off, as the visual improvements do not justify the 54% performance loss compared to Low. A pragmatic approach is to select the Low or Medium preset at 1080p, sacrificing some graphical detail to maintain a consistent frame rate.

How This Combo Ranks

This specific combination of the Intel Core i5-14400F and AMD Radeon RX 570 ranks 1651 out of 1717 tested combos in Rust. This places it in the bottom 4% of all configurations, indicating that it is a very low-performing pairing for this particular game. The rank reflects the significant bottleneck imposed by the GPU, which holds back the otherwise capable CPU.

The CPU itself is a strong performer, with an average benchmark score of 32508 and a percentile rank of 88 among all CPUs. Its nearest rival, the Intel Core i7-12800H, has a nearly identical average score of 32513, with a deltaPct of 0%. This means the i5-14400F is not the source of the low combo ranking. Instead, the GPU’s 74th percentile standing and its measured FPS results drag the overall combo down.

The disparity between the CPU’s high benchmark scores and the combo’s low ranking in Rust highlights the game’s sensitivity to GPU performance. While the CPU can handle the game’s physics and simulation calculations, the rendering pipeline is entirely dependent on the GPU. The data shows that even with a top-tier processor, the RX 570’s limitations prevent this combo from achieving a competitive rank.

CPU Role

The Intel Core i5-14400F provides ample processing power for Rust, with 10 cores and 16 threads running at a base clock of 2.50 GHz and a boost clock of 4.70 GHz. Its 20 MB of shared L3 cache and support for both DDR4 and DDR5 memory make it a versatile and capable gaming processor. In synthetic benchmarks, it achieves a Cinebench R23 multi-core score of 21914 and a single-core score of 3093, demonstrating strong performance in both multi-threaded and single-threaded workloads.

The CPU’s benchmark scores place it in the 88th percentile of all CPUs, with an average score of 32508. Its nearest rivals, including the AMD Ryzen 5 PRO 7645 and Intel Core i7-13705H, show deltaPct values of 0.2% or less, indicating that the i5-14400F is competitive with other mid-range processors. This suggests that in a balanced system, the CPU would not be a limiting factor in Rust, which is known to be CPU-intensive in its simulation and building mechanics.

However, the measured FPS data shows no evidence of CPU bottlenecking. The 4K results are uniformly low across all settings, which is a classic sign of GPU saturation. If the CPU were the limiting factor, we would expect to see similar frame rates across different resolutions, but the data shows a clear and consistent drop as resolution increases. This confirms that the CPU’s capabilities are not being fully utilized due to the GPU’s inability to keep up.

Measured FPS Breakdown

At 1920x1080, the data shows a clear progression from Low to Ultra. The Low preset achieves an average of 64.3 FPS, making it the only setting that provides a consistently smooth experience. The Medium preset drops to 45 FPS, which is still playable but with noticeable frame pacing issues. The High preset yields 39.6 FPS, and the Ultra preset falls to 29.4 FPS, both of which are below the threshold for comfortable gameplay in a fast-paced survival title.

Moving to 2560x1440, the performance degrades significantly across all settings. The Low preset averages 45.6 FPS, which is a 29% reduction from the 1080p Low result. The Medium preset averages 33.5 FPS, and the High preset drops to 25 FPS. The Ultra preset at 1440p is particularly poor, with an average of only 17.9 FPS, making it unsuitable for any form of active play.

At 3840x2160, the results are uniformly poor. The Low preset is the best performer at 25.7 FPS, but this is still below the threshold for a playable experience. The Medium preset drops to 15.7 FPS, the High preset to 14.7 FPS, and the Ultra preset to 13.6 FPS. These numbers confirm that the RX 570 is entirely outmatched at 4K, and no settings adjustment can salvage a playable frame rate at this resolution.
