Rust

Rust is a demanding survival title, and this pairing of the Intel Core i5-14400F with the Intel Arc B580 produces a wide spread of frame rates depending on how you balance resolution and quality. The data shows a system that is clearly capable of smooth 1080p play, but which struggles to maintain playable numbers at 4K. This analysis breaks down exactly what the measured results mean for your settings choices and where the bottleneck sits.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and reveals a GPU-bound situation at higher resolutions. At Low settings, the average frame rate falls from 133 FPS at 1920x1080 to 92 FPS at 2560x1440, then down to 54 FPS at 3840x2160. That is a 41 FPS loss moving from 1080p to 1440p, and another 38 FPS loss moving to 4K. The scaling is nearly linear, which points to the Intel Arc B580 being the limiting factor as pixel count increases.

The pattern repeats at Medium settings, where the average drops from 89 FPS at 1080p to 61 FPS at 1440p, and then to 36 FPS at 4K. High settings show a similar curve: 75 FPS at 1080p, 52 FPS at 1440p, and 31 FPS at 4K. The fact that the 1080p to 1440p drop is consistently around 30% suggests the GPU is doing the heavy lifting, with the CPU having enough headroom to feed frames at the lower resolutions.

At Ultra settings, the situation becomes more pronounced. The average at 1080p is 57 FPS, which is still playable, but this falls to 39 FPS at 1440p and a marginal 23 FPS at 4K. The gap between Low and Ultra at 4K is 31 FPS, meaning that even dropping all the way down to Low settings cannot rescue 4K performance. The data indicates that for this game, 4K is only viable on the absolute lowest preset, and even then the 54 FPS average is below what most players would consider smooth.

The 1080p results tell a different story. At Low settings, the 133 FPS average shows a system that is not being stressed, and the jump to Medium at 89 FPS still leaves plenty of headroom. The fact that the 1080p Medium minimum FPS is 76, while the 4K Medium minimum is 31, confirms that the GPU is the primary constraint at higher resolutions. The i5-14400F, with its 10 cores and 16 threads, is not the limiting factor here; the Arc B580 simply runs out of bandwidth and shading power as resolution climbs.

How This Combo Ranks

In the database of tested combinations, this specific pairing of the i5-14400F and Arc B580 ranks 2815 out of 3723 combos for Rust. This places it in the lower third of all tested systems, which is a useful reference point for expectation setting. The rank is a composite measure that considers performance across all settings and resolutions, and the data shows that while the combo is far from the worst, it is not competitive with high-end configurations.

The individual components tell a slightly different story. The i5-14400F sits at the 83rd percentile among all CPUs, meaning it outperforms the majority of processors in general benchmarks. Its average benchmark score of 32279 puts it in close company with the AMD Ryzen 7 PRO 8840U, which scores 32233 (a 0.1% delta), and the Intel Core i9-11900 at 32226 (a 0.2% delta). It also edges out the AMD Ryzen 7 6800HS, which scores 32354, a -0.2% delta, and the Intel Core i7-12800H at 32121, a 0.5% delta. These are all near-identical scores, indicating that the CPU is a solid mid-range performer that should not bottleneck most gaming workloads.

The Arc B580, on the other hand, sits at the 68th percentile among all GPUs, with an average benchmark score of 23021. Its nearest rivals include the AMD Radeon RX 580 2048SP at 23061 (-0.2% delta), the NVIDIA GeForce RTX 2080 at 22895 (0.6% delta), the NVIDIA GeForce RTX 3080 at 23172 (-0.7% delta), and the NVIDIA P106-100 at 23249 (-1% delta). The fact that it trades blows with an RTX 3080 in synthetic benchmarks is notable, but the Rust results show that this does not translate to consistent high frame rates at demanding settings.

The combination rank of 2815 out of 3723 suggests that while each component is respectable on its own, the pairing does not excel in Rust specifically. The CPU is more than adequate, but the GPU's performance at 4K drags the overall score down. If you are building for 1080p, this combo is likely fine, but the data suggests that pushing to 1440p or 4K will require compromises that put the system in the lower quartile of tested configurations.

At Medium settings, the drop is from 89 FPS to 36 FPS. The GPU's average benchmark score of 23021 places it near the NVIDIA GeForce RTX 3080 (23172, -0.7% delta), but the measured Rust results show it cannot sustain high frame rates at 4K.

Q: What settings preset gives the best balance of quality and performance at 1440p?

A: At 2560x1440, Medium settings provide an average of 61 FPS with a minimum of 52 FPS and a maximum of 71 FPS. This is the only preset at this resolution that stays above 60 FPS on average. High settings drop to 52 FPS, while Low hits 92 FPS but sacrifices visual quality. Ultra falls to 39 FPS, which is not recommended for smooth play.

Q: Can this combo handle 4K gaming in Rust?

A: The data shows that 4K is only playable on Low settings, where the average is 54 FPS. Medium drops to 36 FPS, High to 31 FPS, and Ultra to 23 FPS. These numbers are below the 60 FPS threshold most players target, so 4K is not a viable option for this pairing unless you are comfortable with low quality and sub-60 frame rates.

Q: How does the combo rank compared to other tested systems?

A: This pairing ranks 2815 out of 3723 combos for Rust. This places it in the lower third of all tested configurations, indicating that while it is functional, it is not a top-tier performer for this specific game. The CPU ranks in the 83rd percentile among all CPUs, but the GPU's 68th percentile ranking and the demanding nature of Rust at high resolutions pull the overall combo rank down.

Settings Recommendations

For 1920x1080, the data supports using Medium settings as the sweet spot. The average FPS of 89 with a minimum of 76 and maximum of 103 provides a smooth experience with a significant visual upgrade over Low. If you prioritize frame rate above all else, Low settings at 133 FPS is the clear choice, but Medium is the best balance of quality and performance. High settings at 75 FPS are also viable, but Ultra at 57 FPS is borderline and not recommended for competitive play.

At 2560x1440, Medium settings are the only option that maintains an average above 60 FPS, with 61 FPS and a minimum of 52. Low settings at 92 FPS are smoother, but the visual downgrade is substantial. High at 52 FPS is playable but not ideal, and Ultra at 39 FPS should be avoided. If you have a 1440p monitor, Medium is the recommended preset for this combo.

At 3840x2160, the data is blunt: only Low settings are worth considering. The 54 FPS average is below the 60 FPS target, but it is the only preset that approaches playability. Medium at 36 FPS, High at 31 FPS, and Ultra at 23 FPS are all too slow for any real-time gameplay. If 4K is a requirement, you will need to accept Low settings and frame rates in the 50s, or consider a different GPU.

The measured FPS rows show a clear trend: this combo is a 1080p performer. At that resolution, you have the freedom to choose between High and Medium without sacrificing smoothness. At 1440p, you are locked into Medium for a consistent 60 FPS experience. At 4K, you are locked into Low for anything close to playable. The data does not support pushing this system beyond 1440p for a quality experience.

Measured FPS Breakdown

At 1920x1080, the results are as follows: Low settings deliver an average of 133 FPS, with no minimum or maximum reported. Medium settings provide an average of 89 FPS, with a minimum of 76 and a maximum of 103. High settings drop to an average of 75 FPS, while Ultra falls to 57 FPS. The jump from Low to Medium is a 44 FPS loss, while moving from Medium to High is a 14 FPS loss, and from High to Ultra is an 18 FPS loss.

At 2560x1440, Low settings average 92 FPS, which is a 41 FPS drop from the 1080p Low result. Medium settings average 61 FPS, with a minimum of 52 and a maximum of 71. High settings average 52 FPS, and Ultra averages 39 FPS. The spread from Low to Ultra is 53 FPS, showing that the GPU is heavily taxed as quality increases. The Medium minimum of 52 FPS indicates occasional dips below the average, which is worth noting for sensitive players.

At 3840x2160, Low settings average 54 FPS, which is the only result above 50 FPS. Medium settings average 36 FPS, with a minimum of 31 and a maximum of 42. High settings average 31 FPS, and Ultra averages 23 FPS. The drop from 1440p Low to 4K Low is 38 FPS, and the drop from 1080p Low to 4K Low is 79 FPS. These numbers confirm that 4K is a significant step too far for the Arc B580 in Rust.

The minimum FPS data is only available for Medium settings at each resolution: 76 at 1080p, 52 at 1440p, and 31 at 4K. This shows that even the "smooth" Medium preset at 1440p can dip below 60 FPS during demanding scenes. The maximum FPS values for Medium are 103 at 1080p, 71 at 1440p, and 42 at 4K, indicating that the frame rate is highly variable depending on the game world state.

CPU Role

The Intel Core i5-14400F is a 10-core, 16-thread processor based on the Raptor Lake architecture, built on Intel's 10 nm process. It has a base clock of 2.50 GHz and a boost clock of 4.70 GHz, with a 65 W TDP. The cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and a 20 MB shared L3 cache. This is a desktop part on the Intel Socket 1700 platform, supporting DDR4 and DDR5 memory in dual-channel mode.

In Rust, the CPU's role is to manage the game's simulation, including entity updates, physics, and network synchronization. The benchmark results for the i5-14400F show strong multithreaded performance, with a Cinebench R23 multicore score of 21645 and a single-core score of 3055. The Geekbench multicore score is 11268, and the single-core score is 2058. These numbers indicate that the CPU is more than capable of handling the game's logic, and the data supports this: at 1080p, the frame rates are high enough that the GPU is clearly the primary driver of performance.

The CPU's 16 threads are particularly relevant for Rust, which is known to utilize multiple cores for server-side simulation and world streaming. The Passmark multithread score of 25470 and the integer math score of 81524 suggest that the CPU can handle heavy simultaneous workloads without bottlenecking. The nearest rival comparisons show that the i5-14400F is within 0.5% of several other high-end processors, including the AMD Ryzen 7 PRO 8840U and the Intel Core i9-11900, meaning that swapping to a different CPU in this performance class would not yield meaningful FPS gains in Rust.

The fact that the FPS drops significantly from 1080p to 4K, while the CPU's benchmark scores remain constant, confirms that the processor is not the limiting factor. At 1080p Low, the 133 FPS average is likely near the CPU's frame output limit, but at higher resolutions, the GPU's rendering load takes over. The i5-14400F's 10 cores and 20 MB of L3 cache are sufficient for Rust's demands, and the data suggests that overclocking or upgrading the CPU would not improve the 4K results, which are firmly GPU-bound.
