Rust

The Intel Core i5-10400F paired with the NVIDIA GeForce RTX 4070 presents a distinct profile in Rust, where the CPU's mid-range standing and the GPU's high-tier placement create a system that is consistently playable but constrained by resolution and preset demands. The recorded data shows a clear pattern: at 4K, the system crosses the 60 FPS threshold only at lower presets, while at 1440p and 1080p, it achieves playable frame rates across all tested settings, with the Ultra preset being the most demanding yet still viable option.

Measured FPS Breakdown

The benchmark results for this combination are organized by resolution and preset, providing a clear view of performance scaling. At 3840x2160, the average frame rates are as follows: Low settings deliver 88.9 FPS, Medium settings deliver 62.6 FPS, High settings deliver 51.2 FPS, and Ultra settings deliver 37.2 FPS. The gap between Low and Ultra at 4K is substantial, with a difference of 51.7 FPS, indicating that the GPU is heavily taxed by the highest quality settings at this resolution. Notably, the step from Medium to High incurs a drop of 11.4 FPS, which is significant for maintaining a smooth experience near the 60 FPS mark.

Moving to 2560x1440, the same system shows much stronger performance. Low settings produce 129.2 FPS, Medium produces 103.8 FPS, High produces 89.3 FPS, and Ultra produces 64.9 FPS. The scaling here is more gradual, with each preset tier reducing the average by roughly 15 to 24 FPS. The Ultra preset remains above the playable threshold, but the margin is slim at 4.9 FPS above 60. At 1920x1080, the results are the highest of the three resolutions. Low settings reach 147.1 FPS, Medium reaches 127.4 FPS, High reaches 121.9 FPS, and Ultra reaches 94.9 FPS. The difference between Low and Ultra at 1080p is 52.2 FPS, which is similar in magnitude to the 4K spread, but all values are comfortably above the playable threshold.

Across all resolutions, the data indicates a consistent pattern: the RTX 4070 provides a strong baseline, but the i5-10400F becomes a limiting factor as resolution decreases and frame rates rise. At 1080p, the frame rates are high enough that CPU overhead likely caps the maximum output, while at 4K, the GPU is the primary bottleneck, especially at High and Ultra presets where the average drops below 60 FPS.

Best Settings per Resolution

The database identifies the most demanding preset that remains at or above 60 FPS for each resolution, which serves as the optimal balance between visual quality and performance. At 3840x2160, the best settings are Medium, which achieves an average of 62.6 FPS. This is the only preset above Low that clears the threshold, as High falls to 51.2 FPS and Ultra to 37.2 FPS. Medium offers a modest 2.6 FPS margin over the playable threshold, so users should expect occasional dips below 60 in demanding scenes, but the average remains viable.

At 2560x1440, the best settings are Ultra, with an average of 64.9 FPS. This is a notable result because it means the system can run the game at the highest quality preset at this resolution while still maintaining a frame rate above the playable threshold. The margin is only 4.9 FPS, which is tighter than the 1080p Ultra margin but still acceptable for most gameplay scenarios. For users who prioritize stability over maximum quality, High at 89.3 FPS or Medium at 103.8 FPS would provide larger buffers.

At 1920x1080, the best settings are also Ultra, with an average of 94.9 FPS. This provides a much larger margin of 34.9 FPS over the threshold, making it the most comfortable high-quality experience of the three resolutions. The data shows that at 1080p, the system has ample headroom to handle the Ultra preset without approaching the 60 FPS limit, and even the most demanding settings leave room for background tasks or temporary frame drops.

CPU and GPU Roles

The interaction between the Intel Core i5-10400F and the NVIDIA GeForce RTX 4070 in Rust is best understood by examining how frame rates scale with resolution and preset changes. The CPU sits at the 68th percentile among all tested processors, while the GPU is at the 81st percentile, indicating that the graphics card is relatively stronger than the processor in the broader hardware landscape. This imbalance manifests in the benchmark data.

At 3840x2160, the GPU is the dominant factor. The drop from Low to Ultra is 51.7 FPS, which is a 58% reduction from the Low preset's 88.9 FPS. This large swing is characteristic of GPU-bound scenarios, where increasing pixel count and shading complexity directly impact the rendering load. The CPU's role is less prominent at this resolution because the frame rates are lower, giving the processor more time to prepare frames. The fact that High drops below 60 FPS while Medium stays above it suggests that the GPU's fill rate and memory bandwidth are the limiting factors at 4K.

At 2560x1440, the balance shifts slightly toward the CPU. The frame rate spread from Low (129.2 FPS) to Ultra (64.9 FPS) is 64.3 FPS, which is a 50% reduction. While the GPU still handles the visual load, the higher frame rates at Low and Medium presets mean the CPU must process more draw calls and game logic per second. The i5-10400F, with its 6 cores and 12 threads, appears capable of sustaining these rates, but the margin at Ultra (64.9 FPS) is close to the threshold, indicating that both components are working near their limits.

At 1920x1080, the CPU becomes the more significant constraint. The spread from Low (147.1 FPS) to Ultra (94.9 FPS) is 52.2 FPS, but all values are high. The fact that Low only reaches 147.1 FPS, rather than much higher, suggests that the CPU cannot push frame rates beyond this point even when the GPU is underutilized. This is a classic sign of a CPU bottleneck at lower resolutions. The RTX 4070 is capable of much higher frame rates in other scenarios, but the i5-10400F's single-thread performance and memory bandwidth limit the overall output. The recorded Cinebench R23 single-core score of 1451 and multi-core score of 10283 support this interpretation, as the CPU's single-thread capability is modest compared to its multi-thread performance.

Similar Performance Alternatives

The nearest rivals in the database provide context for how this specific CPU and GPU combination compares to other hardware. For the Intel Core i5-10400F, the closest alternatives in terms of average benchmark score are the Intel Xeon 6756E, which scores 14163 and is 0.2% higher, and the Intel Core 7 160UL, which scores 14232 and is 0.3% lower. The AMD EPYC 7552 scores 14115 and is 0.5% higher, while the AMD Ryzen 3 7320C scores 14277 and is 0.6% lower. These deltas are all within a single percentage point, meaning that swapping the i5-10400F for any of these processors would yield nearly identical performance in Rust. The Ryzen 3 7320C is particularly interesting because it is a lower-tier part, yet its average score is only 0.6% below the i5-10400F, suggesting that the i5-10400F is not far ahead of more budget-oriented CPUs in synthetic benchmarks.

For the NVIDIA GeForce RTX 4070, the nearest rivals include the NVIDIA Tesla P4, which scores 37628 and is 0.1% higher, and the AMD Radeon RX Vega 56, which scores 37507 and is 0.4% higher. The NVIDIA GeForce RTX 4080 Mobile scores 38135 and is 1.3% higher, while the AMD Radeon PRO W6400 scores 37157 and is 1.3% lower. These small deltas indicate that the RTX 4070's performance in Rust would be nearly indistinguishable from these alternatives. The RTX 4080 Mobile being only 1.3% faster is notable, as it suggests that mobile variants of higher-tier GPUs do not offer a meaningful advantage over the desktop RTX 4070 in this game. Conversely, the RX Vega 56, an older AMD card, is essentially matched with the RTX 4070 in the database's average scores, which could imply that Rust's engine does not fully utilize the newer GPU's features.

The Verdict

This PC configuration can run Rust successfully, but the experience varies significantly by resolution. At 3840x2160, the system clears the 60 FPS playable threshold only on Low and Medium presets, with the best setting being Medium at 62.6 FPS. Users who want to play at 4K will need to accept reduced visual quality, as High and Ultra presets are not playable. At 2560x1440, the situation improves dramatically: all four presets are playable, with Ultra achieving 64.9 FPS. This makes 1440p the sweet spot for this combo, as it allows the highest quality settings while staying above 60 FPS, albeit with a slim margin. At 1920x1080, the system excels, with Ultra averaging 94.9 FPS and Low reaching 147.1 FPS. Every preset at 1080p is comfortably playable, making this the most forgiving resolution for the hardware. The verdict is straightforward: the system is fully capable of running Rust at 1080p and 1440p with high or ultra settings, but 4K users must dial back to Medium or Low to maintain playable frame rates.
