Rust

Resolution Scaling

The measured FPS data for Rust with the Intel Core i7-14700KF and NVIDIA GeForce RTX 5070 shows a steep performance drop as resolution climbs, but the pattern is not uniform across settings. At Low settings, the average frame rate falls from 245.3 FPS at 1920x1080 to 168.1 FPS at 2560x1440, then to 96.6 FPS at 3840x2160. That is a 60.6% reduction from 1080p to 4K, which indicates the GPU becomes the dominant constraint at higher resolutions even on the lowest preset. The gap between Low and Ultra at each resolution widens dramatically as resolution increases, confirming that pixel throughput is the limiting factor.

At High settings, the drop from 140.4 FPS at 1080p to 96.4 FPS at 1440p is a 31.3% decline, and then to 53.4 FPS at 4K represents another 44.6% drop from 1440p. The 4K High result of 53.4 FPS is below the 60 FPS threshold that many consider the minimum for smooth gameplay. Ultra settings at 4K produce just 41.9 FPS, which is nearly unplayable for fast-paced survival action. The scaling behavior shows that Rust's rendering load is heavily resolution-bound, with the RTX 5070's 12 GB of GDDR7 memory and 192-bit bus being tested severely at 4K.

The Medium preset follows a similar trajectory: 162 FPS at 1080p, 111.3 FPS at 1440p, and 66.6 FPS at 4K. The consistency of the scaling pattern across all four settings presets suggests that the game's engine does not scale efficiently with resolution — the frame rate drops are roughly proportional to the pixel count increase, rather than being mitigated by the CPU's headroom. The i7-14700KF's 20 cores and 28 threads are not the bottleneck at 4K, as evidenced by the fact that Low settings at 4K still achieve 96.6 FPS while High settings at the same resolution drop to 53.4 FPS, a 44.7% difference that can only be attributed to GPU load.

CPU Role

The Intel Core i7-14700KF is a 20-core, 28-thread processor based on the Raptor Lake architecture, running at a 3.40 GHz base clock with a 5.60 GHz boost. Its benchmark results place it in the 96th percentile of all CPUs tested, with an average benchmark score of 70104. This is effectively tied with the Intel Core i7-14700K, which scores 70074 (a 0% deltaPct), and the AMD Ryzen 9 9950X at 70420 (-0.4% deltaPct). The CPU's multithreaded strength is evident in Cinebench R23 multicore score of 44557, while its single-core score of 6290 in the same test indicates strong per-thread performance.

In Rust, the CPU's role is most apparent at 1080p with Low settings, where the system achieves 245.3 FPS. This high frame rate is only possible because the CPU can feed the GPU with enough draw calls and physics updates. The i7-14700KF's 33 MB of shared L3 cache and 2 MB per-core L2 cache help with the game's asset streaming and world simulation. At 1440p Low, the frame rate drops to 168.1 FPS, which still shows the CPU is not the limiting factor — the GPU is being tasked with more pixels. The gap between Low and Ultra at 1080p is 139.1 FPS (245.3 vs 106.2), which is a 56.7% difference, indicating that the CPU can handle the extra rendering work but the GPU's fill rate becomes the constraint.

The data suggests that at 1080p, the i7-14700KF provides ample headroom, but it is not the primary performance driver in Rust. The game's results are more sensitive to GPU settings than to CPU clock speeds. The CPU's 5.60 GHz boost clock and 20 cores do not translate into proportional FPS gains because Rust's engine is not fully multithreaded. The single-thread performance, as measured by Cinebench R23 single-core score of 6290, is more relevant, but even this does not prevent the GPU from becoming the bottleneck at higher resolutions.

GPU Role

The NVIDIA GeForce RTX 5070 is built on the Blackwell 2.0 architecture with a 5 nm process node, featuring 6,144 shading units, 48 RT cores, and 192 tensor cores. Its 12 GB of GDDR7 memory operates at 1750 MHz with an effective 28 Gbps, delivering 672.0 GB/s of bandwidth across a 192-bit bus. The GPU's base clock is 2325 MHz with a boost of 2512 MHz, and its FP32 performance is rated at 30.87 TFLOPS. In the benchmark database, the RTX 5070 holds the 83rd percentile of all GPUs, with an average score of 41687. Its nearest rivals include the AMD Radeon Pro 5300 at 41610 (0.2% deltaPct) and the NVIDIA GeForce RTX 3090 at 41441 (0.6% deltaPct), placing the RTX 5070 in a competitive position.

In Rust, the GPU's role is decisive at 4K resolution. The Ultra preset at 3840x2160 yields 41.9 FPS, which is 61.4% lower than the Low preset at the same resolution (96.6 FPS). This massive gap underscores how the GPU's shading and memory bandwidth are stretched by the game's high-detail textures and draw distances. The 12 GB VRAM capacity is sufficient for 1080p and 1440p, where the High preset achieves 140.4 FPS and 96.4 FPS respectively, but at 4K Ultra, the memory bus width and bandwidth become limiting factors. The 672.0 GB/s bandwidth is not enough to sustain the texture streaming required at 4K, causing the frame rate to plummet.

The RTX 5070's boost clock of 2512 MHz helps at lower resolutions, where the 1080p Low result of 245.3 FPS shows the GPU can operate near its peak. However, the 4K results indicate that the GPU's raw compute power is insufficient for Rust's demanding post-processing and shadow effects at high settings. The texture rate of 482.3 GTexel/s and pixel rate of 201.0 GPixel/s are not enough to maintain 60 FPS at 4K on High settings, which produces 53.4 FPS. The data confirms that the RTX 5070 is a capable 1440p card for Rust, but 4K gaming requires reducing settings to Medium (66.6 FPS) or Low (96.6 FPS) to achieve playable frame rates.

How This Combo Ranks

The Intel Core i7-14700KF and NVIDIA GeForce RTX 5070 combination ranks 264th out of 1717 tested combos in Rust, placing it in the top 15.4% of all systems in the database. This is a strong result, but not a top-tier ranking, which reflects the game's heavy reliance on GPU performance at higher resolutions. The CPU's 96th percentile ranking does not translate to a similarly high combo rank because Rust's frame rates are more constrained by the RTX 5070's mid-range positioning (83rd percentile).

The rank of 264 out of 1717 combos indicates that this system is well above average, but there are 263 other combinations that achieve higher average FPS in Rust. These likely include GPUs with higher memory bandwidth and more shading units, such as the RTX 3090, which is a close rival in benchmark scores (41441 vs 41687 for the RTX 5070). The 0.6% deltaPct between these two GPUs is small, but in a game like Rust, even small differences in GPU performance can affect the final ranking. The combo's position suggests it is best suited for 1440p gaming, where it can maintain high frame rates, rather than 4K, where the GPU becomes the limiting factor.

Measured FPS Breakdown

The measured FPS data for Rust shows consistent scaling across all four settings presets at each resolution. At 1920x1080, the system achieves 245.3 FPS on Low, 162 FPS on Medium, 140.4 FPS on High, and 106.2 FPS on Ultra. The difference from Low to Ultra is 139.1 FPS, with the largest single drop occurring between Medium and High (21.6 FPS). At 2560x1440, the results are 168.1 FPS on Low, 111.3 FPS on Medium, 96.4 FPS on High, and 74.9 FPS on Ultra. The drop from Low to Ultra is 93.2 FPS, with the largest decline between Medium and High (14.9 FPS).

The scaling from 1080p to 4K at each setting is as follows: Low drops from 245.3 to 96.6 (60.6% reduction), Medium drops from 162 to 66.6 (58.9% reduction), High drops from 140.4 to 53.4 (62.0% reduction), and Ultra drops from 106.2 to 41.9 (60.5% reduction). The uniformity of these percentage reductions across settings confirms that the GPU is the consistent bottleneck at higher resolutions, regardless of the quality preset.

Settings Recommendations

For a smooth gaming experience at 1920x1080, the High preset is the optimal choice, delivering 140.4 FPS with only a 21.6 FPS penalty compared to Medium. Ultra at 1080p yields 106.2 FPS, which is still playable but not necessary given the modest visual gains. At 2560x1440, the High preset at 96.4 FPS is the best balance, as Medium at 111.3 FPS is only slightly faster but may not offer significant visual improvements. The Ultra preset at 1440p (74.9 FPS) is acceptable but approaches the lower limit of smooth gameplay.

At 3840x2160, the Medium preset at 66.6 FPS is the recommended setting, as it provides a playable frame rate while maintaining reasonable visual quality. The Low preset at 96.6 FPS is smoother but sacrifices visual fidelity, while High at 53.4 FPS and Ultra at 41.9 FPS are below the 60 FPS threshold for comfortable play. The data indicates that the RTX 5070 is best paired with 1440p High settings for the best overall experience, with 1080p High serving as a high-refresh-rate alternative and 4K Medium as a compromise for resolution enthusiasts. The system's performance across all settings and resolutions demonstrates that it is a versatile combo for Rust, with the primary trade-off being between visual quality and frame rate at higher resolutions.
