Rust

The Intel Core i5-10400F paired with the NVIDIA GeForce RTX 5070 delivers a playable but inconsistent experience in Rust, with performance scaling that clearly shifts from a GPU-bound state at 4K to a more balanced, CPU-influenced state at 1080p. The measured frame rates across three resolutions and four quality presets reveal a system that can push high refresh rates at 1080p but struggles to maintain a smooth 60 FPS at 4K on higher settings. This combination ranks 1118th out of 3723 tested combos in Rust, placing it in the upper third of all configurations, though the data shows that its strengths are heavily dependent on resolution and settings choices.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings, indicating that the RTX 5070’s rendering load scales predictably with pixel count. At Low settings, the average frame rate falls from 149 FPS at 1920x1080 to 98 FPS at 3840x2160, a reduction of 34% that demonstrates the GPU is still the primary bottleneck even at the lowest quality preset. The gap narrows slightly at Medium, where 128 FPS at 1080p drops to 66 FPS at 4K, a 48% decrease, and at High, the 121 FPS at 1080p falls to 55 FPS at 4K, a 55% reduction. This widening percentage gap as settings increase shows that higher quality presets amplify the GPU’s workload faster than the resolution increase alone.

At Ultra settings, the scaling becomes more dramatic: 104 FPS at 1080p collapses to 42 FPS at 4K, a 60% loss. This suggests that the Ultra preset introduces effects that disproportionately tax the GPU at higher resolutions, likely related to shadow quality and draw distance, which are particularly demanding in Rust’s large open-world environments. The 1440p results sit predictably between the two extremes: 131 FPS at Low, 111 FPS at Medium, 94 FPS at High, and 71 FPS at Ultra, showing a smoother degradation curve that indicates the CPU can still feed the GPU adequately at this mid-range resolution.

The data reveals that the limiting component changes across the resolution spectrum. At 4K, the GPU is clearly the bottleneck, as the frame rates at Medium (66 FPS) and High (55 FPS) are far below what the i5-10400F’s six cores and 12 threads can logically support in a survival title. At 1080p, however, the scaling from Low (149 FPS) to Ultra (104 FPS) suggests the CPU begins to assert itself, as the 30% difference between Low and Ultra is smaller than the 58% difference seen at 4K between the same two presets. This indicates that at 1080p, the i5-10400F’s single-thread performance, measured at 1451 in Cinebench R23, starts to cap the maximum achievable frame rate, preventing the RTX 5070 from fully stretching its legs.

GPU Role

The RTX 5070’s 12 GB of GDDR7 memory on a 192-bit bus provides 672.0 GB/s of bandwidth, which is substantial for Rust’s texture streaming and large map data. The measured frame rates at 4K Ultra (42 FPS) and 4K High (55 FPS) suggest that the GPU’s 30.87 TFLOPS of FP32 compute and 80 ROPs are being heavily utilized, but the memory subsystem appears adequate, as there is no catastrophic drop-off between Medium and High that would indicate a VRAM capacity issue. The card’s 48 RT cores and 192 tensor cores are present, but Rust does not appear to leverage ray tracing heavily, so these resources likely contribute little to the measured performance.

The GPU’s boost clock of 2512 MHz and base clock of 2325 MHz are relatively modest for the 50-series, yet the card still manages 149 FPS at 1080p Low. This performance level places the RTX 5070 at the 82nd percentile of all GPUs in the database, with an average benchmark score of 40377. Its nearest rivals, such as the AMD Radeon Pro 580 with a deltaPct of 0.1% and the NVIDIA RTX A500 Mobile with a deltaPct of 2%, are all within 2% of the RTX 5070’s average score, indicating that in synthetic benchmarks, the card sits in a tightly contested performance tier. However, in Rust, the GPU’s real-world behavior shows that it is more than capable at lower resolutions but becomes the clear limiter at 4K Ultra, where the 42 FPS average is below the 60 FPS threshold many players target.

The 5 nm process node and 31,100 million transistors on a 263 mm² die give the RTX 5070 a high transistor density of 118.3M per mm², which contributes to its efficiency, but the 250 W TDP and 600 W suggested PSU indicate it draws significant power under load. The card’s 6144 shading units and 192 TMUs are well-matched for rasterization-heavy titles like Rust, but the data shows that even with these resources, 4K Ultra is not a viable preset for this combo, as the 42 FPS average falls well below the 55 FPS at High and 66 FPS at Medium. This progression suggests that each step down in settings yields roughly 10-13 FPS improvement at 4K, making Medium the first preset that approaches playable frame rates.

FAQ

Q: What is the best resolution for this combo in Rust?

A: The data shows 1920x1080 is the strongest resolution, with all four presets exceeding 100 FPS on average, from 104 FPS at Ultra to 149 FPS at Low. At 2560x1440, only Low (131 FPS) and Medium (111 FPS) break the 100 FPS mark, while at 3840x2160, no preset reaches 100 FPS, with Low being the highest at 98 FPS.

Q: Is 4K gaming viable with the RTX 5070 and i5-10400F in Rust?

A: Viability depends on the settings preset. At 4K Low, the average FPS is 98, which is playable, but at 4K Medium it drops to 66 FPS, and at 4K High it falls to 55 FPS. The 4K Ultra preset averages only 42 FPS, which is not smooth for a survival game requiring quick reactions.

Q: How does the i5-10400F compare to its closest CPU rivals in synthetic benchmarks?

A: The i5-10400F has an average benchmark score of 14185, placing it at the 68th percentile of all CPUs. Its nearest rival, the Intel Xeon 6756E, scores 14163 with a deltaPct of 0.2%, while the AMD EPYC 7552 scores 14115 with a deltaPct of 0.5%. The Intel Core 7 160UL and AMD Ryzen 3 7320C are slightly ahead at 14232 and 14277 respectively, with deltaPct values of -0.3% and -0.6%.

Q: What is the FPS difference between Low and Ultra settings at each resolution?

Q: Does the RTX 5070 have enough VRAM for Rust at 4K?

A: The RTX 5070 has 12 GB of GDDR7 memory with 672.0 GB/s bandwidth. The measured FPS data does not show a sudden cliff between Medium and High at 4K (66 to 55 FPS), which would indicate VRAM overflow. The gradual decline suggests the 12 GB capacity is sufficient, but the GPU’s compute limits are reached at Ultra settings.

Q: How does the combo rank among all tested configurations?

A: This combo ranks 1118th out of 3723 tested combos in Rust, placing it in the top 30% of all configurations. This mid-tier ranking reflects the CPU’s 68th percentile standing and the GPU’s 82nd percentile, with the combination performing better than the CPU’s percentile but worse than the GPU’s percentile, indicating the CPU holds the system back in some scenarios.

How This Combo Ranks

The combo ranks 1118th out of 3723 tested combos in Rust, a position that places it in the upper third of all configurations tested. This ranking is somewhat surprising given the individual component percentiles: the i5-10400F sits at the 68th percentile of all CPUs, while the RTX 5070 sits at the 82nd percentile of all GPUs. The combination’s rank is lower than the GPU’s percentile might suggest, indicating that the CPU is the limiting factor in this pairing for Rust’s specific workload. Rust’s heavy reliance on single-thread performance, as evidenced by the CPU’s Cinebench R23 single-core score of 1451, likely prevents the RTX 5070 from reaching its full potential in many scenarios.

In synthetic benchmarks, the RTX 5070’s nearest rivals are all within 2% of its average score: the AMD Radeon Pro 580 at 0.1% delta, the AMD Radeon Pro WX 7100 at 0.8%, and the NVIDIA RTX A500 Mobile at 2%. This tight clustering suggests that in raw compute, the RTX 5070 is not dramatically faster than these workstation cards, yet in Rust, the consumer-oriented drivers and architecture of the 50-series likely provide an advantage. The CPU’s nearest rivals show a similar pattern, with the Intel Core 7 160UL at -0.3% and the AMD Ryzen 3 7320C at -0.6% being slightly faster, while the Intel Xeon 6756E at 0.2% and AMD EPYC 7552 at 0.5% are slightly slower.

The rank of 1118 indicates that many combinations with weaker GPUs but stronger CPUs likely outperform this pairing in Rust, as the game’s simulation and world logic can bottleneck on the CPU. At 1080p Low, the 149 FPS average shows the system can deliver high frame rates, but the fact that the 4K Ultra preset only reaches 42 FPS suggests the GPU is not the sole constraint. The data implies that upgrading to a CPU with better single-thread performance, such as those with higher Cinebench R23 single-core scores, would improve the 1080p and 1440p results more than upgrading the GPU would improve the 4K results.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all presets. The Low preset averages 149 FPS, making it the only setting that approaches 144 Hz refresh rates. Medium averages 128 FPS with a min of 109 FPS and max of 147 FPS, providing a smooth experience with some headroom. High averages 121 FPS, and Ultra averages 104 FPS, with the latter still being highly playable for competitive or casual sessions. The spread from Low to Ultra is 45 FPS, showing that the GPU can handle the increased workload at this resolution without the CPU becoming a hard bottleneck.

At 2560x1440, the frame rates drop noticeably but remain respectable. Low averages 131 FPS, which is still above 120 FPS for smooth gameplay. Medium averages 111 FPS with a min of 94 FPS and max of 128 FPS, indicating some frame pacing variability but generally good performance. High averages 94 FPS, which is acceptable for most players, while Ultra averages 71 FPS, dipping below the 75 FPS threshold that many consider the minimum for a good experience. The 60 FPS difference between Low and Ultra at this resolution is the largest of any resolution, suggesting the GPU’s workload scales significantly with settings.

At 3840x2160, the combo struggles to maintain high frame rates. Low averages 98 FPS, which is surprising given the 4K resolution, but it is the only preset that exceeds 60 FPS. Medium averages 66 FPS with a min of 56 FPS and max of 75 FPS, putting it right at the edge of playability. High averages 55 FPS, which is below 60 FPS and may cause noticeable stutter in fast-paced situations. Ultra averages 42 FPS, which is not smooth and would be challenging for competitive play. The 56 FPS difference between Low and Ultra at 4K shows that the RTX 5070’s compute resources are stretched to their limits at this resolution, with each settings step yielding roughly 10-13 FPS improvements.

Settings Recommendations

For players targeting 1920x1080, the Ultra preset is the best choice, as it delivers 104 FPS on average while providing the highest visual quality. The 104 FPS average is well above the 60 FPS threshold, and the fact that it only costs 45 FPS compared to Low makes it a worthwhile trade-off for visual fidelity. Players with 144 Hz monitors may prefer High at 121 FPS, but the jump to Ultra is only a 17 FPS loss, which is acceptable for most. The Medium preset at 128 FPS is a good middle ground for those who want higher frame rates, but the measured min of 109 FPS indicates there is some risk of drops below 120 FPS.

At 2560x1440, the Medium preset is the recommended choice, averaging 111 FPS with a min of 94 FPS, which keeps the experience above 90 FPS for most of the session. High at 94 FPS is also viable for players who prioritize visuals over frame rate, but the 111 FPS of Medium offers a better balance. The Ultra preset at 71 FPS is not recommended, as it falls below the 75 FPS threshold and may feel less responsive in Rust’s player-vs-player combat. Low at 131 FPS is ideal for competitive players who want maximum frame rates, but the visual downgrade is significant.

For 3840x2160, the Low preset at 98 FPS is the only setting that provides a consistently smooth experience, and it is the recommended choice for 4K gaming. The Medium preset at 66 FPS is playable but sits close to the 60 FPS minimum, and its min FPS of 56 indicates that drops below 60 FPS are likely during intense moments. High at 55 FPS is not recommended, as it is below 60 FPS and will be noticeable in gameplay. The Ultra preset at 42 FPS should be avoided entirely, as it is not suitable for a game that requires quick reactions and situational awareness. Players who want higher quality at 4K would need to consider a more powerful GPU, as the data clearly shows this combo is GPU-limited at this resolution.
