Rust

The Intel Core i5-14600KF paired with the NVIDIA GeForce RTX 5080 delivers a measured performance profile in Rust that spans from 56.1 FPS at 4K Ultra to 251 FPS at 1080p Low. The CPU, a 14-core/20-thread Raptor Lake part with a 5.30 GHz boost clock, and the GPU, a Blackwell 2.0 chip with 16 GB GDDR7 and a 960.0 GB/s memory bus, combine to place this system 35th out of 1717 tested combos. The CPU carries a launch MSRP of $294, while the GPU has a launch MSRP of 999 USD. Benchmark results indicate a strong pairing, with the CPU sitting in the 93rd percentile of all CPUs and the GPU in the 89th percentile of all GPUs.

Resolution Scaling

The measured FPS data shows a clear and consistent drop as resolution increases from 1920x1080 to 2560x1440 and then to 3840x2160. At Low settings, the average FPS falls from 251 at 1080p to 212.7 at 1440p and then to 125 at 4K. That is a reduction of 126 FPS between 1080p and 4K, but the step from 1440p to 4K is the larger one, with a drop of 87.7 FPS. At Medium settings, the progression is 206.2 FPS at 1080p, 138.6 at 1440p, and 84.7 at 4K. The 1080p-to-1440p drop is 67.6 FPS, while the 1440p-to-4K drop is 53.9 FPS. High settings show 172.6 FPS at 1080p, 117.9 at 1440p, and 72.7 at 4K. Here the 1080p-to-1440p drop is 54.7 FPS, and the 1440p-to-4K drop is 45.2 FPS. Ultra settings yield 133.9 FPS at 1080p, 90.5 at 1440p, and 56.1 at 4K, with drops of 43.4 and 34.4 FPS respectively.

The pattern indicates that the GPU becomes the limiting component as resolution climbs. At 1080p, even Ultra settings maintain an average above 130 FPS, suggesting that the CPU is capable of feeding the GPU at lower resolutions. The steep decline from 1080p to 4K at every preset—especially the 125 FPS at 4K Low versus 251 at 1080p Low—points to the RTX 5080 being pushed to its limits by the higher pixel count. The scaling is not linear; the 4K Low result is exactly half of the 1080p Low result, while the 4K Ultra result is less than half of the 1080p Ultra result (56.1 vs 133.9). This non-linear behavior is typical of a GPU-bound scenario at 4K, where memory bandwidth and shading throughput become the primary constraints.

GPU Role

The RTX 5080’s specifications directly influence these results. It features 16 GB of GDDR7 memory on a 256-bit bus, delivering 960.0 GB/s of bandwidth. The base clock is 2295 MHz, with a boost clock of 2617 MHz, and the memory runs at 1875 MHz (30 Gbps effective). The GPU’s average benchmark score is 59188, placing it in the 89th percentile of all GPUs. In synthetic tests, it scores 8637 in 3DMark Steel Nomad DX12, 264461 in Geekbench OpenCL, and 257942 in Geekbench Vulkan. Passmark G3D yields 36565, and Passmark GPU Compute 21789.

Compared to its nearest rivals, the RTX 5080’s average score is 1.6% higher than the Intel Arc A570M (which scores 58239), 2.5% higher than the Intel Arc A580 (57756), and 2.6% higher than the AMD Radeon Pro W5500X (57661). However, it trails the Intel Arc Pro A60 by 1.9% (that card scores 60326). These deltas are small, indicating that the RTX 5080 sits in a tight performance band among its immediate competitors, but its 16 GB frame buffer and high bandwidth are notable for a game like Rust, which can be memory-hungry in large, persistent worlds.

The measured FPS at 4K Ultra—56.1 FPS—shows that even with this GPU, the highest preset at 4K is not enough to maintain a 60 FPS average. At 4K Medium, the average rises to 84.7 FPS, and at 4K Low it reaches 125 FPS. This suggests that the GPU’s raw compute and memory bandwidth are the deciding factors at 4K, and that the 16 GB VRAM is sufficient to avoid capacity-related stutters, as the FPS remains stable across settings.

How This Combo Ranks

The combination of the i5-14600KF and RTX 5080 ranks 35th out of 1717 tested combos in Rust. That places it in the top 2% of all systems tested, a strong result for a mid-range CPU paired with a high-end GPU. The CPU’s percentile of 93 and the GPU’s percentile of 89 both contribute to this ranking. The CPU’s average benchmark score is 49367, which is 0.4% higher than the Intel Core i5-14600K (49166), 0.6% higher than the AMD Ryzen 9 5950X (49062), and 1.4% higher than the Intel Xeon Gold 5318H (48698). It is 0.5% lower than the AMD EPYC 4345P (49595). These deltas show that the i5-14600KF is competitive with a range of high-core-count parts, though it does not lead its immediate rivals by a wide margin.

The GPU’s average score of 59188 is 1.6% above the Intel Arc A570M, 2.5% above the Intel Arc A580, and 2.6% above the AMD Radeon Pro W5500X, but 1.9% below the Intel Arc Pro A60. The tight clustering of these scores means that the RTX 5080’s ranking in Rust is not solely due to its raw GPU performance; the CPU’s strong single-thread and multi-thread capabilities (Cinebench R23 multicore 32889, single-core 4643) help sustain high frame rates at lower resolutions, where the CPU is more likely to be the bottleneck.

Given that the combo ranks 35th out of 1717, it outperforms the vast majority of tested systems. The data shows that the i5-14600KF provides enough processing power to avoid limiting the RTX 5080 at 1080p and 1440p, and even at 4K the CPU is not the primary constraint—the GPU’s performance at Ultra settings is the limiting factor.

Settings Recommendations

Based on the measured FPS rows, the optimal preset depends on the target resolution and frame rate. At 1920x1080, all four presets deliver averages above 130 FPS, with Low at 251, Medium at 206.2, High at 172.6, and Ultra at 133.9. For a 144 Hz monitor, Ultra is the only preset that falls below 144 FPS, but it still exceeds 130. For a 165 Hz display, Low, Medium, and High all exceed 165 FPS, while Ultra does not. At 2560x1440, Low (212.7) and Medium (138.6) are the only presets that exceed 120 FPS; High (117.9) is close, and Ultra (90.5) is below 100. For a 1440p 144 Hz panel, Low and Medium are the best choices, with High being a viable alternative if a 120 FPS target is acceptable. At 3840x2160, only Low (125) exceeds 100 FPS; Medium (84.7) and High (72.7) are above 60, while Ultra (56.1) falls below the 60 FPS threshold. For a 4K 60 Hz display, Medium or High are recommended, as they provide a comfortable margin above 60 FPS. For a 4K 120 Hz panel, Low is the only preset that comes close, though it still falls short of 120.

The data suggests that the RTX 5080 is best utilized at 1440p with Medium or High settings, where it delivers a smooth experience without sacrificing visual quality. At 4K, the GPU is clearly the limiting factor, and users must choose between higher settings and higher frame rates. The measured results show that the step from Medium to High at 4K costs 12 FPS (84.7 to 72.7), while the step from High to Ultra costs 16.6 FPS (72.7 to 56.1). The step from Low to Medium at 4K costs 40.3 FPS (125 to 84.7), which is a larger penalty, indicating that the Medium preset introduces a significant load increase.

Measured FPS Breakdown

The following table lists all measured average FPS values from the FACT PACK:

| Resolution | Settings | Avg FPS |

|------------|----------|---------|

| 3840x2160 | High | 72.7 |

| 3840x2160 | Low | 125 |

| 3840x2160 | Medium | 84.7 |

| 3840x2160 | Ultra | 56.1 |

| 2560x1440 | High | 117.9 |

| 2560x1440 | Low | 212.7 |

| 2560x1440 | Medium | 138.6 |

| 2560x1440 | Ultra | 90.5 |

| 1920x1080 | High | 172.6 |

| 1920x1080 | Low | 251 |

| 1920x1080 | Medium | 206.2 |

| 1920x1080 | Ultra | 133.9 |

At 1080p, the spread from Low to Ultra is 117.1 FPS (251 to 133.9), with the largest single-step drop occurring between Medium and High (33.6 FPS, from 206.2 to 172.6). At 1440p, the spread is 122.2 FPS (212.7 to 90.5), with the largest drop between Medium and High (20.7 FPS, from 138.6 to 117.9). At 4K, the spread is 68.9 FPS (125 to 56.1), with the largest drop between Low and Medium (40.3 FPS, from 125 to 84.7). These numbers illustrate that the performance cost of each preset tier is not uniform across resolutions; at 4K, the jump from Low to Medium is disproportionately expensive, while at 1080p the jump from Medium to High is the most costly.

The data also shows that the RTX 5080 maintains a playable experience at 4K only on Low and Medium presets, with High and Ultra falling below 75 FPS. At 1440p, all presets exceed 90 FPS, making it the sweet spot for this combo. At 1080p, the CPU’s strong single-thread performance (Cinebench R23 single-core 4643) likely helps sustain high frame rates, as the GPU is not fully saturated at lower resolutions. The measured results confirm that the i5-14600KF and RTX 5080 form a balanced pairing for Rust, with the GPU becoming the primary bottleneck only at 4K Ultra.
