Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data for Rust with the Intel Core i5-14600K and NVIDIA GeForce RTX 3070 reveals a clear and predictable scaling pattern as resolution increases, but the magnitude of the drops tells an important story about where the bottleneck lies. At 1920x1080 with Low settings, the combo produces 185.8 FPS, which drops to 127.2 FPS at 2560x1440 — a reduction of roughly 32%. Moving further to 3840x2160, the average falls to 74.6 FPS, which is a 41% drop from the 1440p figure and a 60% drop from the 1080p baseline. This is a steep decline, but it is not uniform across all settings presets, which hints at how the workload shifts.

Looking at the Ultra preset, the pattern is even more dramatic. At 1080p Ultra, the system delivers 77.9 FPS. At 1440p Ultra, it falls to 57.2 FPS — a 27% reduction. At 4K Ultra, the average drops to 33.2 FPS, which is a 42% reduction from 1440p and a 57% reduction from 1080p. The fact that the percentage drop from 1440p to 4K is larger at Ultra settings (42%) than at Low settings (41%) suggests that as the GPU becomes more heavily loaded with higher-quality rendering, its limitations become more pronounced. The RTX 3070's 8 GB of GDDR6 memory and 448.0 GB/s bandwidth are likely being saturated at the higher resolutions combined with demanding settings.

The data implies that at 1080p, the CPU still has significant headroom to feed the GPU. The i5-14600K's 14 cores and 20 threads, boosting up to 5.30 GHz, appear capable of keeping up with the RTX 3070 at lower resolutions. However, as resolution climbs to 4K, the GPU becomes the primary limiting factor. The evidence for this is the consistent FPS drop across all settings at 4K — even at Low settings, the system only manages 74.6 FPS, which is below what the CPU alone could theoretically drive if the GPU were not the constraint. The gap between Low and Ultra at 4K is 74.6 FPS versus 33.2 FPS, a 41.4 FPS difference, whereas at 1080p the gap is 185.8 FPS versus 77.9 FPS, a 107.9 FPS difference. This compression of the settings-based spread at higher resolutions strongly indicates that the GPU is the bottleneck at 4K, while at 1080p, the CPU and GPU are more balanced, allowing settings to have a larger impact on performance.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-14600K is a 14-core, 20-thread processor built on Intel's Raptor Lake architecture, manufactured on a 10 nm process. Its base clock is 3.50 GHz, and it boosts up to 5.30 GHz. The CPU has an 80 KB L1 cache per core, a 2 MB L2 cache per core, and a shared 24 MB L3 cache. In Rust, which is known for its heavy server-side simulation and physics calculations, the CPU's multi-threaded performance is often critical. The benchmark scores support this — in Cinebench R23, the i5-14600K scores 32881 in multicore and 4642 in single-core. In Geekbench, it scores 15846 multicore and 2803 single-core. These scores position the CPU in the 93rd percentile overall, with an average benchmark score of 49166.

Compared to its nearest rivals, the i5-14600K is essentially neck-and-neck with the AMD Ryzen 9 5950X, which has an average score of 49062 — a delta of just 0.2%. It is 0.4% behind the Intel Core i5-14600KF, which scores 49367, and 0.9% behind the AMD EPYC 4345P, which scores 49595. The i5-14600K is 1% ahead of the Intel Xeon Gold 5318H, which scores 48698. This level of performance suggests that the CPU is unlikely to be the primary bottleneck in most scenarios, particularly at lower resolutions.

The measured FPS data corroborates this. At 1080p Low, the system hits 185.8 FPS, which is a very high frame rate that indicates the CPU is feeding the GPU efficiently. At 1080p Ultra, the FPS drops to 77.9 — a substantial reduction that aligns more with GPU load than CPU limitations. The fact that the CPU can push 185.8 FPS at Low settings shows that it has the headroom to handle high-refresh-rate gaming at 1080p. However, at 4K, even at Low settings, the FPS drops to 74.6, which is closer to the 1080p Ultra result. This suggests that at 4K, the CPU is no longer the limiting factor — the GPU is. The CPU's high boost clock of 5.30 GHz and 14 cores provide ample processing power for Rust's simulation-heavy gameplay, but the data shows that the GPU's rendering capabilities cap the overall performance at higher resolutions.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core i5-14600K and NVIDIA GeForce RTX 3070 ranks 753rd out of 1717 tested combos in Rust. This places it in the upper-middle tier of all tested configurations, which is a notable result given the hardware involved. A rank of 753 out of 1717 means that roughly 56% of tested combos perform worse, while 44% perform better. This is a solid position, but it also indicates that there are many combinations that deliver higher frame rates in Rust.

The ranking suggests that while the i5-14600K is a high-end CPU (93rd percentile) and the RTX 3070 is a mid-to-high-end GPU (72nd percentile), their combined performance in Rust is not at the very top. This is likely due to the RTX 3070's 8 GB VRAM being a limiting factor at higher resolutions and settings, as Rust can be demanding on memory. The data shows that at 4K Ultra, the combo only manages 33.2 FPS, which is a poor result for a system with this hardware. At 1080p Low, however, it achieves 185.8 FPS, which would be competitive with many higher-end configurations.

The rank of 753 also reflects the balance of the combo. The CPU is clearly not the bottleneck, given its high percentile ranking and benchmark scores. The GPU, while capable, is the more likely constraint in demanding scenarios. For a game like Rust, where the CPU handles a lot of the simulation logic, this combination is well-matched at 1080p and 1440p, but it falls behind at 4K. The data implies that if a user were to prioritize higher resolutions, a GPU with more VRAM and bandwidth would be needed to improve the ranking. Conversely, at 1080p, this combo's rank could be considered strong, as it delivers frame rates well above 60 FPS at all settings except Ultra, which still achieves 77.9 FPS.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 3070 is built on the Ampere architecture, fabricated on Samsung's 8 nm process, and features 17,400 million transistors on a 392 mm² die. Its base clock is 1500 MHz, with a boost clock of 1725 MHz. The GPU has 8 GB of GDDR6 memory on a 256-bit bus, providing a bandwidth of 448.0 GB/s. With 5888 shading units, 184 TMUs, 96 ROPs, 46 RT cores, and 184 tensor cores, the RTX 3070 is a capable mid-range card. Its FP32 performance is 20.31 TFLOPS, and it has a TDP of 220 W. In benchmark tests, it scores 22214 in Passmark G3D and 123479 in Geekbench OpenCL, placing it in the 72nd percentile among all GPUs.

The 8 GB VRAM is a critical factor in Rust. The measured FPS data shows a clear pattern: as resolution increases, the performance gap between Low and Ultra settings widens in absolute terms but narrows in relative terms. At 1080p, the difference between Low (185.8 FPS) and Ultra (77.9 FPS) is 107.9 FPS. At 1440p, the difference is 70.0 FPS (127.2 FPS Low versus 57.2 FPS Ultra). At 4K, the difference is 41.4 FPS (74.6 FPS Low versus 33.2 FPS Ultra). This suggests that at 4K, the GPU's VRAM capacity and bandwidth are being stressed, causing the settings-based differences to compress.

The RTX 3070's nearest rivals in benchmark scores include the AMD FirePro S7150, which scores 28409 (0.6% higher), the AMD Radeon RX 6600 XT at 27985 (0.9% lower), and the NVIDIA GeForce GTX 980 Ti at 27956 (1% lower). These deltas are small, indicating that the RTX 3070 is closely matched with these cards in synthetic benchmarks. However, in Rust, the 8 GB VRAM could be a differentiator. The data shows that at 4K Ultra, the FPS drops to 33.2, which is below playable thresholds for many users. This is likely due to the GPU being unable to handle the memory requirements of Rust at 4K Ultra, causing a significant performance hit. The GPU's 448.0 GB/s bandwidth is also a consideration, as higher resolutions require more data to be transferred, and the data suggests that this becomes a bottleneck at 4K.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets. At 1920x1080, the system delivers 185.8 FPS on Low, 127.5 FPS on Medium, 107.9 FPS on High, and 77.9 FPS on Ultra. The progression from Low to Ultra shows a steady decline, with the largest drop occurring between Medium and High (19.6 FPS) and the smallest between High and Ultra (30.0 FPS). The 1080p results indicate that the combo is capable of high refresh rates at lower settings, but even at Ultra, it maintains a playable 77.9 FPS.

At 2560x1440, the FPS figures are 127.2 FPS on Low, 86.8 FPS on Medium, 70.6 FPS on High, and 57.2 FPS on Ultra. The drop from Low to Medium is 40.4 FPS, which is the largest single-step reduction at this resolution. The gap between High and Ultra narrows to 13.4 FPS, suggesting that the GPU is becoming more of a limiting factor as settings increase. At 1440p, the combo can still deliver over 60 FPS on High settings, but Ultra dips below 60 FPS, which may be a concern for users with high-refresh-rate monitors.

At 3840x2160, the results are 74.6 FPS on Low, 49.5 FPS on Medium, 40.3 FPS on High, and 33.2 FPS on Ultra. The drop from Low to Medium is 25.1 FPS, and the drop from Medium to High is 9.2 FPS. The gap between High and Ultra is 7.1 FPS, which is the smallest difference between any two adjacent settings at any resolution. This indicates that at 4K, the GPU is heavily saturated, and the settings have diminishing returns. The 4K Low result of 74.6 FPS is notable, as it shows that the combo can still achieve playable frame rates at 4K if settings are reduced, but the Ultra result of 33.2 FPS is below the 60 FPS threshold that many users consider the minimum for smooth gameplay.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the optimal settings preset depends on the user's resolution and performance goals. At 1920x1080, the High preset delivers 107.9 FPS, which is well above the 60 FPS threshold and provides a good balance between visual quality and performance. The Ultra preset at 77.9 FPS is also playable, but the 30 FPS drop from High to Ultra may not justify the visual improvements, especially if the user prioritizes smoothness. For users with high-refresh-rate monitors (144Hz or higher), the Medium preset at 127.5 FPS or even the Low preset at 185.8 FPS would be more appropriate, as they allow the display to be fully utilized.

At 2560x1440, the High preset at 70.6 FPS is the best choice for maintaining a playable experience with good visual fidelity. The Medium preset at 86.8 FPS offers a smoother experience and is recommended for users who prefer higher frame rates over visual detail. The Ultra preset at 57.2 FPS is borderline, as it falls below 60 FPS, and the data suggests that the visual gains from Ultra over High may not be worth the 13.4 FPS loss. The Low preset at 127.2 FPS is an option for competitive play, but it sacrifices significant visual quality.

At 3840x2160, the situation is more constrained. The Low preset at 74.6 FPS is the only setting that achieves a comfortable frame rate above 60 FPS. The Medium preset at 49.5 FPS is playable but not ideal, and the High preset at 40.3 FPS and Ultra at 33.2 FPS are below the threshold for smooth gameplay. For 4K users, the recommendation is to use the Low preset to maintain a playable experience, or to consider reducing the resolution to 1440p and using the High preset for a better balance of visual quality and performance. The data clearly shows that the RTX 3070's 8 GB VRAM is a limiting factor at 4K, and the settings recommendations reflect that constraint.
