Rust

The Intel Core i5-13400F and AMD Radeon RX 6700 XT combination delivers a solid 1080p experience in Rust, with performance scaling predictably as resolution increases. The data shows this pairing sits at rank 901 out of 1717 tested combos for this game, placing it firmly in the upper-middle tier of systems. The 10-core, 16-thread processor with a 2.50 GHz base and 4.60 GHz boost clock provides ample headroom for Rust's simulation-heavy gameplay, while the 12 GB Radeon RX 6700 XT handles the visual load. The measured frames per second across resolutions and settings reveal a system that can push high refresh rates at 1080p but will require compromises at 4K.

CPU Role

The i5-13400F is built on the Raptor Lake architecture with 10 cores and 16 threads. Its boost clock reaches 4.60 GHz, which is critical for Rust's single-threaded tasks like physics calculations and world generation. The processor's 20 MB of shared L3 cache helps keep frequently accessed data close to the cores, reducing latency in gameplay scenarios.

Benchmark results show the i5-13400F achieving a 3dmark_single_thread score of 960 and a passmark_single_thread score of 3634. These numbers indicate strong per-core performance, which matters in Rust where many game logic threads cannot scale perfectly across all cores. The multi-threaded capabilities are equally robust, with a cinebench_r23_multicore score of 21279 and a passmark_multithread score of 25032. This ensures the CPU can handle background tasks like entity updates and server-side computations without bottlenecking the GPU.

The processor's 82nd percentile ranking among all CPUs places it ahead of most mainstream options. It sits within 0.5% of the AMD Ryzen 5 5600X3D's average score of 25365, showing nearly identical overall compute performance. The data suggests that in Rust, the CPU's high boost clock and substantial cache are more relevant than raw core count, as the game's performance at 1080p Low settings (167.4 FPS) demonstrates the processor's ability to feed the GPU effectively.

GPU Role

The AMD Radeon RX 6700 XT features 12 GB of GDDR6 memory on a 192-bit bus, delivering 384.0 GB/s of bandwidth. This capacity is sufficient for Rust's large textures and draw distances, even at high resolutions. The GPU's boost clock reaches 2581 MHz, with a game clock of 2424 MHz, allowing it to maintain consistent frame delivery under sustained load.

The GPU's 77th percentile ranking among all graphics cards reflects its mid-to-high-end positioning. It scores 19786 in passmark_g3d and 9336 in passmark_gpu_compute, indicating strong rasterization performance. The 2560 shading units and 64 ROPs provide the pixel throughput needed for Rust's complex environments, while the 40 ray accelerators offer optional ray tracing capabilities that the game does not heavily utilize.

The Radeon RX 6700 XT's nearest rival, the AMD Radeon RX 6800, scores 33493 in average benchmark score, which is only 0.7% higher. This proximity shows the 6700 XT delivers near-flagship-level performance in this game. However, the GPU becomes the limiting factor at 4K, where even Low settings only produce 69.4 FPS, compared to 167.4 FPS at 1080p Low.

Resolution Scaling

The measured FPS data reveals clear scaling patterns across the three resolutions tested. At 1080p, the system averages 167.4 FPS on Low settings, dropping to 93.9 FPS on High. Moving to 1440p reduces these figures to 115.9 FPS and 64.9 FPS respectively, representing a 30-31% performance decrease. At 4K, the numbers fall further to 69.4 FPS and 40.5 FPS, showing another 40-38% drop from 1440p.

This scaling pattern indicates the GPU becomes progressively more dominant as the limiting factor at higher resolutions. At 1080p, the CPU's strong single-thread performance allows the GPU to work near its full potential, evidenced by the 167.4 FPS Low setting result. The transition from 1080p to 1440p shows a consistent reduction across all settings, suggesting the system maintains GPU-bound behavior. However, at 4K Ultra, the 28.5 FPS result reveals the GPU's memory bandwidth and compute resources are stretched thin.

The 4K High setting produces 40.5 FPS, which is below the 60 FPS threshold for smooth gameplay. Even 4K Medium only reaches 46.7 FPS. This data clearly shows that 4K gaming with this combo is only viable at Low settings, where 69.4 FPS provides a playable experience. For users targeting higher visual quality at 4K, the GPU would need to be upgraded.

Settings Recommendations

The measured rows point to Medium settings as the best balance for most users. At 1080p Medium, the system delivers 112.7 FPS, which is 20% higher than High settings' 93.9 FPS while maintaining noticeably better visual quality than Low. This frame rate comfortably exceeds the 60 FPS standard and approaches the 144 Hz refresh rate territory for competitive play.

At 1440p, Medium settings produce 76.9 FPS, which remains smooth for most gaming monitors. The High preset at this resolution drops to 64.9 FPS, still playable but with less headroom for demanding scenes. The data suggests that Medium settings provide the most consistent experience across all resolutions, with the least severe frame rate penalties for visual improvements.

For users with high-refresh-rate 1080p monitors, Low settings at 167.4 FPS or Medium at 112.7 FPS are viable options. The Low preset sacrifices visual fidelity but maximizes responsiveness, which is valuable in Rust's player-versus-player combat scenarios. The Ultra preset, while visually impressive, only achieves 72.5 FPS at 1080p and drops to 48 FPS at 1440p, making it a poor choice for gameplay fluidity.

FAQ

Q: Can this system run Rust at 60 FPS on 1080p Ultra settings?

A: Yes, the measured 1080p Ultra average of 72.5 FPS exceeds the 60 FPS threshold. However, the margin is slim, and demanding scenes could cause dips below 60 FPS.

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

A: Based on the data, 1440p with Medium settings (76.9 FPS) offers the best balance of visual quality and performance. 4K is only playable at Low settings (69.4 FPS).

Q: How does the i5-13400F compare to the AMD Ryzen 5 5600X3D?

A: The average benchmark scores are nearly identical, with the i5-13400F at 25236 and the Ryzen 5 5600X3D at 25365, a difference of just 0.5%. Performance in Rust should be similar.

Q: Is the RX 6700 XT's 12 GB VRAM sufficient for Rust?

A: The data shows 12 GB is adequate for all tested settings, including 4K Ultra. The GPU's bottleneck at 4K is compute and bandwidth, not VRAM capacity.

Measured FPS Breakdown

The complete set of measured average FPS values from the data is presented below, organized by resolution and settings preset.

1920x1080 (1080p):

• Low: 167.4 FPS
• Medium: 112.7 FPS
• High: 93.9 FPS
• Ultra: 72.5 FPS

The 1080p results show a clear hierarchy where each settings tier costs approximately 20-30 FPS. The jump from Low to Medium is the largest single-step reduction (54.7 FPS), while the gap between Medium and High (18.8 FPS) and High to Ultra (21.4 FPS) is more moderate.

2560x1440 (1440p):

• Low: 115.9 FPS
• Medium: 76.9 FPS
• High: 64.9 FPS
• Ultra: 48.0 FPS

At 1440p, the Low setting remains above the 100 FPS mark, but Medium drops to 76.9 FPS. The Ultra preset falls below 50 FPS, indicating the GPU's limits at this resolution with maximum visual settings.

3840x2160 (4K):

• Low: 69.4 FPS
• Medium: 46.7 FPS
• High: 40.5 FPS
• Ultra: 28.5 FPS

The 4K data shows only the Low preset achieves a playable frame rate above 60 FPS. Every other setting falls below 50 FPS, with Ultra dipping to 28.5 FPS, which is not suitable for smooth gameplay.

These numbers reveal that the system's performance envelope is well-suited for 1080p and 1440p gaming, with the GPU being the limiting factor at 4K. The CPU's strong single-thread performance ensures it does not bottleneck the GPU at any tested configuration, making the RX 6700 XT the component that determines overall frame rates.
