Rust

Rust presents a demanding workload that scales significantly with resolution, and the measured FPS data for the Intel Core i9-14900K paired with the NVIDIA GeForce RTX 5080 clearly illustrates this. Starting at 1920x1080 on Low settings, the combo delivers an average of 275 FPS. Moving to 2560x1440 on the same Low preset, the average drops to 205 FPS, a reduction of 70 FPS. The leap to 3840x2160 on Low yields an average of 121 FPS, which is 84 FPS lower than the 1440p result. This pattern indicates that while the CPU is capable of driving very high frame rates at lower resolutions, the GPU becomes increasingly burdened as pixel count rises, creating a bottleneck at 4K.

The scaling from 1080p to 4K is more pronounced at higher settings. With the High preset, the average FPS falls from 169 at 1920x1080 to 116 at 2560x1440, and then down to 69 at 3840x2160. The Ultra preset shows a similar trajectory, with averages of 129, 88, and 52 FPS across the three resolutions. The data suggests that at 1080p and 1440p, the i9-14900K's strong single-threaded performance allows the RTX 5080 to stretch its legs, but at 4K, the sheer number of pixels being processed by the GPU dictates the final frame rate, regardless of the CPU's capabilities.

How This Combo Ranks

Within the database of tested combinations, the Intel Core i9-14900K and NVIDIA GeForce RTX 5080 pairing holds a rank of 125 out of 3723 combos for Rust. This places the system in a high percentile, indicating that it outperforms the vast majority of other configurations tested in this game. The ranking reflects the combined strength of the two components, where the CPU's high Cinebench R23 multi-core score of 39399.5 and the GPU's substantial compute power work in tandem to produce solid results.

The CPU's average benchmark score of 79097 places it in the 95th percentile of all CPUs, and when compared to its nearest rivals, the data shows a tight grouping. The Intel Core i9-14900KF scores 79371, which is a 0.3% difference from the i9-14900K, and the AMD Ryzen AI Max+ 395 scores 77740, a 1.7% difference. This suggests that the i9-14900K is performing as expected for a top-tier desktop processor, and its position in the combo rank is likely influenced more by the GPU's performance characteristics in Rust.

GPU Role

The NVIDIA GeForce RTX 5080 is the defining component in this pairing's performance at higher resolutions. It comes equipped with 16 GB of GDDR7 memory on a 256-bit bus, providing a bandwidth of 960.0 GB/s. This memory configuration is a key factor in handling Rust's large textures and draw distances, particularly when the Ultra preset is enabled. The GPU's clock speeds, with a base of 2295 MHz and a boost of 2617 MHz, are the primary drivers of its rendering speed, allowing it to process the complex scenes typical of survival games.

The RTX 5080's raw compute capabilities, including an FP32 throughput of 56.28 TFLOPS, are substantial. However, the measured FPS data shows a clear limitation: at 3840x2160 on Ultra, the average FPS is 52, which is the lowest score recorded for this combo. This indicates that even with 16 GB of VRAM and high clock speeds, the GPU is fully saturated at 4K with maximum settings, and the frame rate is constrained by its pixel throughput and shading rate. The GPU's percentile rank of 87 among all GPUs, with an average benchmark score of 56083, confirms that it is a high-end part, but Rust's demanding nature at 4K Ultra pushes it to its limits.

FAQ

Measured FPS Breakdown

The measured FPS data for Rust provides a comprehensive look at how the i9-14900K and RTX 5080 perform across different settings. At 1920x1080, the combo shows its strength, with the Low preset delivering an average of 275 FPS. The Medium preset at this resolution averages 200 FPS, with a minimum of 170 and a maximum of 230. High settings bring the average down to 169 FPS, and Ultra settings further reduce it to 129 FPS. This demonstrates that even at 1080p, the Ultra preset imposes a significant load on the GPU, cutting the frame rate nearly in half compared to Low.

Moving to 2560x1440, the averages for each preset are 205 FPS on Low, 138 FPS on Medium (with a minimum of 117 and maximum of 158), 116 FPS on High, and 88 FPS on Ultra. The gap between Low and Ultra widens at this resolution, showing that the GPU's workload is increasing. At 3840x2160, the data shows the most strain: Low averages 121 FPS, Medium averages 81 FPS (with a minimum of 69 and maximum of 94), High averages 69 FPS, and Ultra drops to an average of 52 FPS. The progression clearly shows that for smooth 4K gameplay, users will need to select lower presets, as the Ultra preset's 52 FPS average is below the 60 FPS target for many players.

CPU Role

The Intel Core i9-14900K provides the computational foundation for this combo. With 24 cores and 32 threads, it is a high-core-count processor that excels in multi-threaded workloads, as evidenced by its Cinebench R23 multi-core score of 39399.5. Its boost clock of 6.00 GHz is exceptional for single-threaded tasks, which is reflected in the single-core score of 2262.5 in Cinebench R23. This combination of high core count and high clocks is particularly beneficial for Rust, which is known to be sensitive to CPU performance in certain scenarios, such as when many entities are on screen or during base building.

The CPU's performance in Rust is likely a major reason why the 1080p and 1440p frame rates are so high. At 1920x1080 on Low, the 275 FPS average suggests that the CPU is not a limiting factor, as it can feed the GPU with enough data to maintain high frame rates. The CPU's percentile ranking of 95 among all CPUs, with an average benchmark score of 79097, places it among the best processors available. Its nearest rival, the Intel Core i9-14900KF, has a nearly identical score with a delta of -0.3%, indicating that the two perform at the same level. The data suggests that the i9-14900K's role is to provide a stable, high-performance platform that allows the RTX 5080 to operate at its full potential until the GPU itself becomes the bottleneck at higher resolutions.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target resolution and desired frame rate. For players with a 1080p monitor, the High preset is a solid choice, delivering an average of 169 FPS, which is well above the refresh rate of most standard displays. The Medium preset offers an even higher 200 FPS average, but the visual fidelity may be lower than what the hardware is capable of. The Ultra preset at 1080p still provides a playable 129 FPS, but the performance gain from dropping to High is substantial, making High the more efficient choice for a balance of visuals and speed.

At 2560x1440, the Medium preset stands out, with an average of 138 FPS and a minimum of 117 FPS. This offers a smooth experience that is likely sufficient for most high-refresh-rate 1440p monitors. The High preset at 1440p averages 116 FPS, which is also playable, but the drop from Medium is noticeable. The Ultra preset at 1440p, with an average of 88 FPS, is borderline for competitive play but may be acceptable for a more cinematic experience. For 4K gaming, the data points to the Low preset as the only option for high frame rates, with an average of 121 FPS. The Medium preset at 4K averages 81 FPS, which is playable, but the High preset's 69 FPS and Ultra's 52 FPS are below the 60 FPS threshold that many consider the minimum for a smooth experience. Therefore, the Medium preset at 4K is the recommended choice, as it provides a playable frame rate while maintaining a moderate level of visual quality.
