Rust

The Intel Core i5-14400F paired with the AMD Radeon RX 6600 is a mid-range desktop combination that, in Rust, demonstrates a clear ceiling at higher resolutions while delivering smooth performance at standard 1080p. The data places this combo at rank 2875 out of 3723 tested configurations, meaning it sits in the 77th percentile of tested combos — a solidly above-average position, though not among the elite. The combination’s ranking reflects a balanced pairing where the CPU’s strong multi-threaded performance supports the GPU’s capable 1080p output, but the GPU’s 8 GB frame buffer and 128-bit memory bus become limiting factors as resolution climbs. Benchmark results indicate this is a dependable setup for competitive play at 1080p, playable at 1440p with reduced settings, and not viable for 4K at the tested presets.

How This Combo Ranks

The Intel Core i5-14400F + AMD Radeon RX 6600 combination ranks 2875th out of 3723 tested combos in Rust, placing it in the upper-middle tier of the database. This position is notable because the CPU itself holds an 83rd percentile ranking among all CPUs, while the GPU sits at only the 63rd percentile among all GPUs. The disparity suggests that the combo’s overall rank is dragged down by the GPU’s relative weakness rather than elevated by the CPU’s strength. In practical terms, the CPU is capable of far more than the GPU can feed it at higher resolutions, making the pairing somewhat lopsided — the processor has headroom that remains unused when the graphics card becomes the bottleneck.

The combo outperforms 23% of tested configurations, which is respectable for a mainstream build, but the gap between the CPU’s and GPU’s individual percentile rankings (83 vs 63) is the key takeaway. A stronger GPU would likely push this combo significantly higher in the rankings, as the CPU’s 10 cores and 16 threads provide ample processing power for Rust’s simulation-heavy gameplay. The measured FPS data corroborates this: at 1080p, the combo delivers 126.2 FPS on Low settings, but drops to 20.6 FPS at 4K Ultra — a 6.1x reduction that is far steeper than what a balanced pairing would typically show.

CPU and GPU Roles

The scaling between resolutions and presets reveals that the GPU becomes the dominant constraint as resolution increases, while the CPU maintains consistent headroom throughout. At 1920x1080, the difference between Low and Ultra settings is 69.2 FPS (126.2 to 57.0), indicating that the GPU is the primary driver of performance changes. However, when moving from 1080p Low to 1440p Low, the FPS drops from 126.2 to 85.1 — a 32.6% reduction that is purely resolution-driven, not settings-driven. This suggests the GPU’s fill rate and memory bandwidth are being taxed more heavily as pixel count rises, while the CPU’s workload remains relatively constant.

At 2560x1440, the pattern continues: Medium settings yield 61.0 FPS, but High drops to 48.5 FPS and Ultra falls to 34.6 FPS. The GPU is clearly the limiting factor here, as the CPU’s multi-threaded score of 21645 in Cinebench R23 (and 25470 in Passmark multithread) indicates it can handle Rust’s server-side and simulation threads without issue. The real bottleneck appears at 3840x2160, where even Low settings only manage 53.2 FPS, and Medium falls to 33.7 FPS. This is a classic GPU-bound scenario: the RX 6600’s 224.0 GB/s memory bandwidth and 8 GB frame buffer cannot sustain the data throughput required at 4K, regardless of how efficient the CPU is.

The CPU’s role is more apparent at lower resolutions and higher settings. At 1080p Ultra, the combo achieves 57.0 FPS, which is only 12.3% below the 60 FPS threshold — a modest deficit given that the GPU is working at near-peak capacity. The CPU’s single-core performance (3055 in Cinebench R23 single-core) ensures that frame pacing remains stable even when the GPU is saturated. However, the data shows no scenario where the CPU causes a frame rate collapse; the GPU is always the first to hit its limit.

Best Settings per Resolution

For 1920x1080, the most demanding preset that stays at or above 60 FPS is High, which delivers an average of 69.7 FPS. This is the sweet spot: Ultra drops to 57.0 FPS (below the 60 FPS threshold), while Medium offers 86.1 FPS and Low hits 126.2 FPS. High provides the best visual fidelity while maintaining a comfortable margin above the playable threshold, making it the recommended setting for most players.

At 2560x1440, the best playable setting is Medium, which averages 61.0 FPS — just barely clearing the 60 FPS bar. High falls to 48.5 FPS and Ultra to 34.6 FPS, both unplayable by this metric. Low runs at 85.1 FPS, but Medium offers a significant visual upgrade for only a 28.3% FPS penalty, making it the optimal choice for 1440p gaming.

For 3840x2160, no tested preset reaches 60 FPS. The best result is Low at 53.2 FPS, which is 11.3% below the threshold. Medium (33.7 FPS), High (31.9 FPS), and Ultra (20.6 FPS) are all firmly in unplayable territory. The verdict data confirms this: the 4K row lists no playable settings, so the recommendation is to avoid 4K with this combo or accept a sub-60 FPS experience on Low.

Similar Performance Alternatives

Looking at the CPU’s nearest rivals, the Intel Core i5-14400F is closely matched by the AMD Ryzen 7 PRO 8840U (0.1% faster avg score), Intel Core i9-11900 (0.2% faster), AMD Ryzen 7 6800HS (0.2% slower), and Intel Core i7-12800H (0.5% faster). These deltas are negligible — all four processors fall within a 0.7% performance band of each other. For Rust specifically, any of these CPUs would deliver virtually identical frame rates in CPU-bound scenarios, meaning the choice between them comes down to platform features (socket, memory support, integrated graphics) rather than gaming performance. The i5-14400F’s 10 cores and 16 threads are matched by the Ryzen 7 6800HS’s 8 cores and 16 threads, but the i5’s higher boost clock (4.70 GHz vs the 6800HS’s lower boost) gives it a slight edge in single-threaded tasks.

On the GPU side, the AMD Radeon RX 6600’s nearest rivals are the NVIDIA Quadro K6000 (0.0% delta), NVIDIA GeForce RTX 4050 Mobile (0.1% slower), NVIDIA Tesla K20m (0.3% slower), and NVIDIA RTX 2000 Ada Generation (0.4% faster). The RTX 4050 Mobile is particularly interesting as a comparison point — it is a laptop GPU with similar average benchmark scores (19049 vs 19036), suggesting that desktop users with an RTX 4050 Mobile in a laptop should expect comparable Rust performance to this combo. The Quadro K6000 is a much older workstation card but still matches the RX 6600’s average score, though it lacks modern features like ray tracing and DirectX 12 Ultimate support. The RTX 2000 Ada Generation is slightly faster (0.4%) and would provide a marginal FPS improvement in GPU-bound scenarios.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results: Low averages 126.2 FPS, Medium 86.1 FPS, High 69.7 FPS, and Ultra 57.0 FPS. The step-down from Low to Medium is 40.1 FPS (31.8%), from Medium to High is 16.4 FPS (19.0%), and from High to Ultra is 12.7 FPS (18.2%). This progressive decline indicates that Rust’s settings scale roughly linearly with GPU load at 1080p, with no sudden cliffs until Ultra.

At 2560x1440, the numbers drop across the board: Low averages 85.1 FPS, Medium 61.0 FPS, High 48.5 FPS, and Ultra 34.6 FPS. The percentage drop from Low to Medium is 28.3%, from Medium to High is 20.5%, and from High to Ultra is 28.7%. The larger drop from High to Ultra at 1440p (compared to 1080p) suggests that Ultra settings introduce effects that are disproportionately expensive at higher pixel counts.

At 3840x2160, the combo struggles: Low averages 53.2 FPS, Medium 33.7 FPS, High 31.9 FPS, and Ultra 20.6 FPS. The jump from Low to Medium is a 36.7% reduction, but the jump from Medium to High is only 5.3%, and High to Ultra is 35.4%. This erratic scaling indicates that at 4K, the GPU is so heavily constrained that certain settings (like texture quality) have minimal impact, while others (like shadow resolution) cause large drops.

The Verdict

This PC can run Rust, but only at specific resolutions and settings. At 1920x1080, the combo clears 60 FPS on Low, Medium, and High settings, with High being the best visual quality that remains playable (69.7 FPS). Ultra falls below the threshold at 57.0 FPS, so it should be avoided. At 2560x1440, the combo clears 60 FPS on Low (85.1 FPS) and Medium (61.0 FPS), with Medium being the recommended setting for the best balance of visuals and performance. High (48.5 FPS) and Ultra (34.6 FPS) are not playable. At 3840x2160, no settings reach 60 FPS — the best is Low at 53.2 FPS, which is below the playable threshold.

The verdict data confirms this: 1080p lists High, Low, and Medium as playable; 1440p lists Low and Medium; 4K lists none. For players with a 1080p monitor, this is a solid setup that can handle Rust at High settings with a comfortable FPS margin. For 1440p users, Medium settings are required to stay above 60 FPS. For 4K, this combo is not recommended unless the player is willing to accept sub-60 FPS performance.
