How This Combo Ranks

The combo's rank of 2208 out of 2953 places it in the 25th percentile of all tested systems for Rust. This is a below-average result, meaning that roughly three-quarters of the tested hardware combinations deliver higher frame rates. The data suggests that this pairing is not optimized for Rust's specific engine demands, as the general benchmark percentiles for both components (83rd for the CPU and 68th for the GPU) are significantly higher than the in-game ranking.

This discrepancy points to a potential bottleneck or compatibility issue within the game itself. The CPU's general performance is strong, with an average score of 32750, which is 0.2% higher than the AMD Ryzen 7 PRO 6850H and 0.1% higher than the Intel Core i5-14600T. The GPU's general performance is also respectable, with an average score of 23021, which is 0.6% lower than the NVIDIA GeForce RTX 2080. However, when combined in Rust, the result is a mid-pack experience, indicating that the game's engine may not fully utilize the available hardware resources.

The ranking is consistent across all settings, with the combo never achieving a top-half position in any resolution. This suggests a systemic issue with the pairing rather than a setting-specific anomaly. The data shows that the combo is more competitive at 1080p, but still falls short of the top performers, which likely have both higher-end CPUs and GPUs.

GPU Role

The Intel Arc B580 features 12 GB of GDDR6 memory on a 192-bit bus, providing a bandwidth of 456.0 GB/s. The GPU operates at a base and boost clock of 2670 MHz, with a memory clock of 2375 MHz (19 Gbps effective). These specifications are crucial for Rust, which is known to be memory-intensive due to its large world maps and numerous entities.

The GPU's impact is most evident at 4K resolution, where the average FPS drops to 31 at High settings. At 1080p High, the average is 75 FPS, showing a clear scaling pattern that is heavily dependent on pixel count. The GPU's compute capabilities, with a FP32 rating of 13.67 TFLOPS, are sufficient for 1080p gaming but struggle to maintain high frame rates at 4K.

The GPU's nearest rival in the database is the AMD Radeon RX 580 2048SP, which it trails by 0.2% in average benchmark score. However, the B580's performance in Rust is more closely aligned with its 68th percentile ranking, indicating that it performs as expected for its general compute power. The 12 GB VRAM is a significant advantage for Rust, as the game can consume large amounts of memory for textures and world data, but the GPU's raw throughput limits its ability to leverage this capacity at higher resolutions.

The data shows that the GPU's performance scales poorly with quality settings at 4K. The jump from Low (54 FPS) to Medium (36 FPS) is a 33% drop, while the jump from Medium to High (31 FPS) is a 14% drop. This diminishing return pattern suggests that the GPU is hitting a memory bandwidth or compute ceiling, as increasing settings adds more load without a corresponding increase in performance.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings produce an average of 133 FPS, which is the only preset that clears the 120 FPS mark. Medium settings yield 89 FPS, with a minimum of 76 FPS and a maximum of 103 FPS. High settings drop to 75 FPS, and Ultra falls to 57 FPS. These numbers indicate that 1080p is the optimal resolution for this combo, with playable frame rates on all presets except Ultra, which is borderline.

Moving to 2560x1440, the performance drops significantly. Low settings average 92 FPS, which is a 31% decrease from the 1080p Low result. Medium settings average 61 FPS, with a minimum of 52 FPS and a maximum of 71 FPS. High settings average 52 FPS, and Ultra drops to 39 FPS. At this resolution, only Low and Medium presets are viable for consistent 60 FPS gameplay.

At 3840x2160, the combo struggles. Low settings average 54 FPS, which is the only preset that approaches playability. Medium settings average 36 FPS, with a minimum of 31 FPS and a maximum of 42 FPS. High settings average 31 FPS, and Ultra averages 23 FPS. None of these 4K presets reach the 60 FPS threshold, making 4K gaming a non-starter for this pairing.

The data shows a consistent pattern of performance degradation across all settings as resolution increases. The gap between Low and Ultra settings widens at higher resolutions, indicating that the GPU becomes the primary bottleneck. At 1080p, the difference between Low and Ultra is 76 FPS, while at 4K, the difference is 31 FPS, showing that the GPU has less headroom to work with at higher pixel counts.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial across all settings. At Low settings, the average FPS drops from 133 to 54, a 59% decrease. At Medium settings, the drop is from 89 to 36, a 60% decrease. High settings drop from 75 to 31, a 59% decrease, and Ultra drops from 57 to 23, a 60% decrease. This consistent scaling pattern indicates a GPU-bound scenario.

The near-uniform percentage drop across all settings is a classic sign of a GPU limitation. If the CPU were the bottleneck, we would expect the performance drop to be less severe at higher resolutions, as the GPU would be the limiting factor at 1080p but the CPU would catch up at 4K. However, the data shows the opposite: the performance drop is consistent, meaning the GPU is always the limiting component.

The scaling from 1080p to 1440p shows a similar pattern. Low settings drop from 133 to 92 FPS, a 31% decrease. Medium drops from 89 to 61 FPS, a 31% decrease. High drops from 75 to 52 FPS, a 31% decrease, and Ultra drops from 57 to 39 FPS, a 32% decrease. This consistent scaling reinforces the conclusion that the GPU is the primary bottleneck.

The 4K to 1440p scaling is slightly less severe, with Low dropping from 54 to 92 FPS (a 70% increase going down), but the pattern remains consistent. The data suggests that the GPU's memory bandwidth of 456.0 GB/s is insufficient to handle the increased pixel throughput at higher resolutions, leading to the observed frame rate drops.

CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Raphael. It has a base clock of 3.70 GHz and a boost clock of 4.70 GHz, with a 65W TDP. The CPU features 32 MB of shared L3 cache and supports DDR5 memory with a bandwidth of 83.2 GB/s.

The CPU's general benchmark scores are strong, with a Cinebench R23 multi-core score of 21765 and a single-core score of 3072. The PassMark multithread score is 25645, and the single-thread score is 3689. These scores place the CPU at the 83rd percentile of all CPUs, indicating that it is a capable processor for gaming workloads.

In Rust, the CPU's role is less critical than the GPU at higher resolutions. The data shows that at 1080p Low, the combo achieves 133 FPS, which is likely CPU-limited in some scenarios. However, the consistent scaling pattern across resolutions suggests that the GPU becomes the bottleneck as resolution increases. The CPU's high single-core performance, as evidenced by its Cinebench R23 single-core score of 3072, is sufficient for Rust's game logic and physics calculations.

The CPU's memory bandwidth of 83.2 GB/s is adequate for feeding the GPU, but it is lower than the GPU's 456.0 GB/s bandwidth. This mismatch can cause bottlenecks in data-intensive scenarios, but the benchmark results do not show this being a major issue at 1080p. The CPU's 6 cores and 12 threads are sufficient for Rust's multi-threaded rendering and simulation tasks, as evidenced by the playable frame rates at lower resolutions.

The CPU's nearest rival, the AMD Ryzen 7 PRO 6850H, scores 0.2% higher in average benchmarks. However, the 7400F's higher boost clock of 4.70 GHz gives it an advantage in single-threaded tasks, which is critical for Rust's game engine. The data indicates that the CPU is not the primary limiting factor in this combo, as the GPU's performance at higher resolutions is the main constraint.
