Rust

The Intel Core i5-13400F paired with the NVIDIA GeForce RTX 3070 is a capable mid-range combination for Rust, a survival game that is notoriously demanding on both CPU and GPU. The benchmark data shows a wide performance envelope across resolutions, with the system capable of exceeding the 60 FPS threshold in most scenarios, though 4K Ultra remains an outlier. The following analysis breaks down the measured performance, component roles, and how this combo stacks up against other tested configurations.

Best Settings per Resolution

At 3840x2160 (4K), the most demanding preset that maintains an average of at least 60 FPS is Low, which delivers an average of 75.4 FPS. This is the only playable setting at this resolution; Medium averages 48.7 FPS, High dips to 44.1 FPS, and Ultra falls to 31.9 FPS. The data indicates that 4K is only viable when most visual features are sacrificed, as the GPU is clearly the limiting factor here.

At 2560x1440 (1440p), the best playable setting is High, which posts an average of 70.0 FPS. This is a significant jump in visual quality over Low (127.7 FPS) and Medium (84.1 FPS), while still clearing the 60 FPS threshold with a modest margin. Ultra remains unplayable at 53.8 FPS, showing that the highest preset is too demanding for this pair at this resolution.

At 1920x1080 (1080p), the system can handle the most demanding preset, Ultra, with an average of 78.2 FPS. This gives the user full access to the game’s visual options without dropping below the playable threshold. The lower presets are all well above 100 FPS, with Low hitting 182.4 FPS, Medium at 124.5 FPS, and High at 102.9 FPS, indicating that 1080p is where this combo truly shines for competitive or high-refresh-rate play.

CPU and GPU Roles

The performance scaling across resolutions reveals a clear division of labor between the CPU and GPU. The CPU, an Intel Core i5-13400F, has 10 cores and 16 threads with a boost clock of 4.60 GHz. It ranks in the 77th percentile against all CPUs, suggesting strong multi-threaded capability for a game like Rust, which uses server-side simulation and physics heavily. The GPU, an RTX 3070 with 8 GB of GDDR6 memory and 5888 shading units, ranks in the 61st percentile against all GPUs.

At 1080p, the system is primarily CPU-bound. The jump from Low (182.4 FPS) to Ultra (78.2 FPS) shows the GPU still matters, but the very high frame rates at lower settings suggest the CPU is feeding frames quickly. The delta between Medium (124.5 FPS) and High (102.9 FPS) is 21.6 FPS, while the delta between High and Ultra is 24.7 FPS, showing a relatively steady drop as GPU load increases.

At 1440p, the GPU begins to take a more dominant role. The average FPS drops from 127.7 (Low) to 70.0 (High), a 57.7 FPS decrease, which is a larger absolute drop than at 1080p. The gap between Medium (84.1 FPS) and High (70.0 FPS) is 14.1 FPS, while Ultra (53.8 FPS) is 16.2 FPS lower than High. This indicates that the GPU’s fill rate and bandwidth (448.0 GB/s) are becoming constraints.

At 4K, the GPU is almost entirely the bottleneck. The average FPS at Low is 75.4, but this drops to 48.7 at Medium and 44.1 at High. The difference between Medium and High is only 4.6 FPS, suggesting that the GPU is running out of pixel throughput, and the CPU is no longer the limiting factor. The RTX 3070’s 8 GB memory and 256-bit bus are likely saturated at this resolution, making higher presets impractical.

Similar Performance Alternatives

For the CPU, the Intel Core i5-13400F’s nearest rivals in terms of average benchmark score are the AMD Ryzen 9 6900HS (25284, 0% delta) and the AMD Ryzen 7 6800H (25201, 0.4% higher). These are mobile processors, but their desktop equivalents would likely behave similarly in Rust, offering comparable multi-threaded performance. The Intel Core 5 120 (25362) and AMD Ryzen 5 5600X3D (25365) are also within 0.3% of the i5-13400F’s score, meaning gamers with those chips could expect nearly identical frame rates in CPU-bound scenarios.

For the GPU, the AMD Radeon RX 7600 XT (17083, 0.7% lower) is the closest match, meaning it would likely deliver the same average FPS at all resolutions and presets. The NVIDIA GeForce GTX 690 (17037, 1% lower) and AMD Radeon HD 7970M (17019, 1.1% lower) are older architectures, but their synthetic scores suggest they could also produce playable frame rates at lower settings, though they lack modern features like DLSS or ray tracing. The NVIDIA Tesla K40c (17468, 1.5% higher) is a compute-focused card, so its gaming performance might not directly translate to Rust.

The Verdict

The data confirms that the Intel Core i5-13400F + NVIDIA GeForce RTX 3070 is a solid pairing for Rust. At 1080p, the system clears the 60 FPS threshold on all presets, including Ultra (78.2 FPS), making it fully playable with maximum visual settings. At 1440p, it remains playable on High (70.0 FPS), Medium (84.1 FPS), and Low (127.7 FPS), but not Ultra (53.8 FPS). At 4K, only the Low preset (75.4 FPS) is playable, while Medium, High, and Ultra all fall below 60 FPS.

The key limitation is the GPU at higher resolutions. The RTX 3070’s 8 GB memory and 448.0 GB/s bandwidth are sufficient for 1440p, but 4K high-detail rendering exceeds its capabilities. For users targeting 4K, the data suggests this combo is only suitable for low-detail play. For 1080p or 1440p, it is a strong performer that will handle Rust’s demanding environments without major compromises.

How This Combo Ranks

Out of 3723 tested combos in the database, this specific CPU-GPU pairing ranks at 1620, placing it in the upper-middle tier of all systems. This ranking reflects that while it is not a high-end enthusiast setup, it outperforms the majority of configurations tested. The percentile rankings for the individual components (CPU at 77th percentile, GPU at 61st percentile) suggest the CPU is relatively stronger than the GPU, which aligns with the observed bottleneck behavior at higher resolutions. The system is a balanced mid-range option that excels at 1080p and handles 1440p well, but it does not have the headroom for 4K high-fidelity gaming.
