Rust

The Intel Core i5-9400 paired with the NVIDIA GeForce RTX 5070 ranks 564th out of 1,717 tested combos in Rust, placing it in the upper third of all configurations. Measured average frame rates span from 45.6 FPS at 4K Ultra to 144.2 FPS at 1080p Low, a wide envelope that reflects the GPU’s high ceiling and the CPU’s mid-range positioning. The data shows a combo that can handle competitive play at 1080p and 1440p, but 4K requires careful settings selection.

Resolution Scaling

The FPS drop from 1080p to 4K is steepest at higher presets. At High settings, the average falls from 112.3 FPS at 1920x1080 to 92.7 at 2560x1440 and then to 54.8 at 3840x2160 — a 51% reduction from 1080p to 4K. At Low settings, the same resolution change yields 144.2 → 123.7 → 96.5, a 33% drop. Medium settings drop 46% (124.2 → 107.6 → 66.9), while Ultra drops 55% (101.6 → 71.4 → 45.6). This pattern indicates that the RTX 5070 becomes the primary limiter at 4K, especially under Ultra geometry and texture loads. The smaller relative drop at Low settings suggests that the i5-9400’s six threads are more involved at lower resolutions, but even then the frame rate remains high. The scaling behavior is consistent with a GPU that has ample headroom at 1080p but is taxed heavily at 4K Ultra.

GPU Role

The RTX 5070 brings 12 GB of GDDR7 memory on a 192-bit bus, with 672.0 GB/s of bandwidth. Its base clock is 2325 MHz and boost reaches 2512 MHz. These specifications translate into strong raw performance: the GPU sits at the 83rd percentile among all GPUs, with an average benchmark score of 41,687. Its nearest rivals include the RTX 3090, which it edges by 0.6% in average score, and the Tesla M40, which is 0.5% ahead. In Rust, the GPU’s capability is evident in the measured results: at 4K Low it delivers 96.5 FPS, while at 4K Ultra it drops to 45.6. The 12 GB VRAM is sufficient for the game’s textures at all tested presets. The launch MSRP of the RTX 5070 is 549 USD. The GPU’s high bandwidth and clock speeds allow it to push high frame rates at 1440p, where even Ultra averages 71.4 FPS.

CPU Role

The Intel Core i5-9400 is a 6-core, 6-thread processor with a base clock of 2.90 GHz and a boost of 4.10 GHz. It has 9 MB of shared L3 cache and a dual-channel DDR4 memory interface with 42.7 GB/s bandwidth. The CPU sits at the 50th percentile among all CPUs, with an average benchmark score of 2,305. Its nearest rivals are all within 0.6% in average score, including the Core i3-10305 (0.2% lower) and the Core i7-8809G (0.6% higher). In Rust, the CPU’s influence is most visible at lower resolutions. At 1080p Low, the combo reaches 144.2 FPS, which is high but not exceptional for a modern GPU. The six threads and 4.10 GHz boost provide enough throughput for smooth gameplay, but the CPU’s mid-range standing likely caps the maximum frame rate in CPU-bound scenes. The Cinebench R23 multi-core score of 7,969 and single-core score of 1,125 confirm a modest processor. The combo’s overall rank of 564 out of 1,717 suggests that the CPU is the weaker link, given the GPU’s 83rd percentile placement.

How This Combo Ranks

The combo ranks 564th out of 1,717 tested configurations in Rust, which places it in the upper third (better than roughly 67% of combos). The GPU’s 83rd percentile and the CPU’s 50th percentile create a mismatch: the RTX 5070 is a high-end part, while the i5-9400 is a mid-range processor. The rank reflects this imbalance — the combo is above average but not near the top. The GPU’s nearest rivals include the RTX 3090, which the RTX 5070 slightly outperforms in average benchmark score, but the CPU’s modest standing prevents the combo from climbing higher. For comparison, the CPU’s nearest rival, the Core i7-8809G, is 0.6% faster in average score, yet the overall combo rank is determined by the interaction of both components. The data indicates that pairing a stronger CPU with this GPU would likely yield a higher rank, but within this specific pairing, the results are consistent with a mid-range CPU and a high-end GPU.

Measured FPS Breakdown

The following table lists all measured average frame rates for this combo in Rust.

| 1920x1080 | Ultra | 101.6 |

At 1080p, every preset exceeds 100 FPS, with Low reaching 144.2 and Ultra still at 101.6. At 1440p, all presets stay above 60 FPS, with Medium at 107.6 and Ultra at 71.4. At 4K, only Low (96.5) and Medium (66.9) exceed 60 FPS; High (54.8) and Ultra (45.6) fall below that threshold. The data shows a clear progression: the higher the resolution, the more the GPU becomes the bottleneck, and the more settings must be lowered to maintain smooth frame rates.

Settings Recommendations

The measured data provides clear guidance for each resolution. At 1080p, all presets are playable, but Ultra (101.6 FPS) offers the highest visual quality while still maintaining a triple-digit average. For a 60 FPS target at 1440p, Medium (107.6) and High (92.7) are both safe choices; Ultra (71.4) also stays above 60, so it is viable for those who prioritize image quality. At 4K, only Low (96.5) and Medium (66.9) meet the 60 FPS threshold. Low is the only preset that provides a comfortable margin, while Medium is borderline. For a balanced experience across resolutions, 1440p Medium delivers high frame rates without sacrificing much detail. At 4K, Low is the recommended preset for smooth gameplay, as High and Ultra fall below 60 FPS. The data shows that this combo is best suited for 1080p and 1440p gaming, with 4K reserved for lower settings.
