Rust

Rust is a demanding survival title that stresses both processor and graphics hardware, and the combination of the Intel Core i5-10400F with the NVIDIA GeForce RTX 3070 Ti produces a distinct performance profile across resolutions and settings. The measured data reveals a system that is highly capable at mainstream resolutions but begins to buckle under the weight of 4K and maximum quality presets, highlighting the balance between the CPU's six cores and the GPU's memory and bandwidth constraints.

Resolution Scaling

The performance drop from 1080p to 4K is steep and consistent across all settings, signaling that the GPU becomes the primary limiting factor as pixel count rises. At High settings, the average frame rate falls from 112 FPS at 1920x1080 to 78.9 FPS at 2560x1440, a reduction of roughly 30%, and then further declines to 45.3 FPS at 3840x2160, which is about 60% below the 1080p figure. This scaling pattern indicates that the RTX 3070 Ti’s rendering pipeline is being saturated by the additional pixel workload, with the CPU’s 12 threads providing enough headroom to avoid bottlenecking at these lower resolutions.

The trend is even more pronounced at the Low preset, where the 1080p result of 150.7 FPS drops to 133 FPS at 1440p and then plummets to 78.6 FPS at 4K. The gap between 1440p and 4K at Low settings is particularly large—a 54.4 FPS difference—suggesting that memory bandwidth and fill rate are critical at 4K, as the GPU’s 608.3 GB/s bandwidth and 169.9 GPixel/s pixel rate are stretched thin. Conversely, the jump from 1080p to 1440p at Low is modest (17.7 FPS), implying that the CPU is still able to feed the GPU efficiently at these settings, but the 4K resolution overwhelms the graphics card’s capabilities.

At Ultra settings, the scaling is brutal: 85 FPS at 1080p drops to 59.4 FPS at 1440p and then to 31.6 FPS at 4K. The 4K Ultra result is less than half of the 1080p Ultra score, and it falls below the 30 FPS threshold that many players consider playable. This data suggests that for 4K gaming, the RTX 3070 Ti is simply outmatched by Rust’s maximum quality settings, and users would need to rely on Lower presets or reduced resolution scaling to maintain smooth gameplay.

GPU Role

The NVIDIA GeForce RTX 3070 Ti is built on the Ampere architecture with 8 GB of GDDR6X memory, a 256-bit bus, and a boost clock of 1770 MHz. This configuration yields a memory bandwidth of 608.3 GB/s and a texture rate of 339.8 GTexel/s, which are substantial figures for a mid-range enthusiast card. However, the 8 GB VRAM capacity appears to be a limiting factor in Rust, particularly at higher resolutions and settings where texture data and draw calls demand more memory than the card can hold comfortably.

The data shows that the GPU’s performance in Rust is heavily influenced by settings, with the gap between Low and Ultra widening as resolution increases. At 1080p, the difference between Low (150.7 FPS) and Ultra (85 FPS) is 65.7 FPS, but at 4K, that gap grows to 47 FPS (78.6 vs. 31.6). This suggests that the card’s shading units (6144) and ray tracing cores (48) are being taxed more severely at higher quality presets, while the memory subsystem struggles to keep up with the increased data throughput.

The GPU’s average benchmark score of 30849 places it in the 74th percentile of all graphics cards, but its nearest rivals show a tight cluster: the AMD Radeon RX 590 GME is only 0.3% behind, while the AMD Radeon RX 6700 is 0.8% ahead. In Rust specifically, the RTX 3070 Ti’s performance at 1440p High (78.9 FPS) is respectable, but the 4K results indicate that the card is closer to mid-range solutions in this title than its raw specs might suggest. The 8 GB VRAM is a notable weakness, as Rust’s open-world environments can quickly consume memory, leading to potential stuttering or texture pop-in beyond what the average FPS figures reveal.

How This Combo Ranks

In the database of tested combinations, this pairing of the Intel Core i5-10400F and NVIDIA GeForce RTX 3070 Ti ranks 734th out of 1717 combos for Rust, placing it in the upper-middle tier of all systems tested. This position reflects a balance where the CPU’s performance is adequate but not outstanding, and the GPU’s capabilities are strong but not elite. The combo’s ranking suggests that while this setup delivers playable frame rates at 1080p and 1440p, it falls behind more balanced pairings that pair higher-end CPUs with similarly powerful GPUs.

The CPU itself sits in the 73rd percentile against all processors, with an average benchmark score of 14168. Its nearest rivals include the AMD EPYC 7552 (0.4% higher), AMD Ryzen 3 7320C (0.8% lower), and Intel Core i5-8500 (1.1% lower). This indicates that the i5-10400F is a solid mid-range performer, but its six cores and 12 threads are not exceptional by current standards, which may explain why the combo ranks lower than some might expect given the GPU’s strength. The GPU’s 74th percentile ranking is similar, but the combination’s 734th placement out of 1717 suggests that the pairing is slightly less effective in Rust than either component’s individual percentile would imply, likely due to the CPU’s limitations in CPU-heavy scenes.

Measured FPS Breakdown

At 1920x1080, the system delivers strong performance across all settings. Low settings produce an average of 150.7 FPS, which is smooth for competitive play, while Medium yields 126.7 FPS, High 112 FPS, and Ultra 85 FPS. The scaling from Low to Ultra shows a 43.6% reduction in frame rate, indicating that the GPU has headroom to handle visual enhancements at this resolution without dropping below playable thresholds. The 1080p results are consistent with the CPU’s ability to maintain high frame rates with 12 threads, as the i5-10400F’s boost clock of 4.30 GHz helps keep the GPU fed.

Moving to 2560x1440, the performance remains solid but shows the onset of GPU saturation. Low settings average 133 FPS, Medium 87.8 FPS, High 78.9 FPS, and Ultra 59.4 FPS. The drop from Low to Medium is particularly sharp (45.2 FPS), suggesting that texture quality and shadow settings have a disproportionate impact on the GPU’s workload at this resolution. The 1440p Ultra result of 59.4 FPS is borderline for 60 Hz displays, but the High preset at 78.9 FPS offers a better balance for most users.

At 3840x2160, the system struggles to maintain high frame rates. Low settings yield 78.6 FPS, which is playable, but Medium drops to 55.7 FPS, High to 45.3 FPS, and Ultra to 31.6 FPS. The 4K Ultra result is below the 30 FPS mark, making it unsuitable for smooth gameplay, and even High settings fall short of 60 FPS. The data indicates that 4K gaming with this combo requires significant settings compromises, with only the Low preset approaching acceptable performance levels.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor based on the Comet Lake architecture, built on Intel’s 14 nm process. It features a base clock of 2.90 GHz and a boost clock of 4.30 GHz, with 12 MB of shared L3 cache. The CPU’s single-thread performance, as measured by Cinebench R23, is 1453 points, while multi-core is 10297 points, which are respectable figures for a mainstream chip. However, Rust’s gameplay often involves physics calculations, entity updates, and server-side logic that can benefit from higher core counts, and the i5-10400F’s six cores may become a bottleneck in crowded or complex scenes.

This is evident in the 1080p results, where the CPU’s influence is more pronounced. At Low settings, the 150.7 FPS average suggests that the CPU is capable of driving high frame rates, but the scaling from Low to Ultra (a 65.7 FPS drop) indicates that the GPU is still the primary limiter. In contrast, at 4K, the CPU’s role diminishes as the GPU becomes fully saturated, and the frame rates are more reflective of the graphics card’s raw power.

The CPU’s average benchmark score of 14168 places it near the AMD EPYC 7552 (0.4% higher) and AMD Ryzen 3 7320C (0.8% higher), but it trails the Intel Core i5-8500 by 1.1%. These close margins suggest that the i5-10400F is comparable to several other mid-range processors, but none of these rivals offer a dramatic performance advantage in Rust. The CPU’s 65 W TDP and DDR4 memory support (dual-channel, 42.7 GB/s bandwidth) are standard for its class, but the lack of integrated graphics and PCIe Gen 3 support may limit future upgradeability. Overall, the data shows that the i5-10400F provides adequate performance for this GPU, but users seeking higher frame rates at 1080p with maximum settings might benefit from a processor with higher single-thread performance.
