# How This Combo Ranks

This AMD Ryzen 5 8400F + NVIDIA GeForce RTX 5070 Ti combination sits at rank 417 out of 3,723 tested combos in Rust, placing it in the top 11.2% of all systems evaluated for this game. That percentile position indicates a high-performing pairing, though not an absolute top-tier one—the data suggests there is meaningful headroom above this combo in Rust's demanding survival sandbox.

The CPU's overall benchmark percentile versus all processors is 77, meaning it outperforms roughly three-quarters of all CPUs tested across the database. The GPU's percentile versus all GPUs is 86, a stronger relative standing. This gap between the two components' individual rankings hints that the graphics card is the more dominant contributor to this combo's Rust performance, though the CPU's 6 cores and 12 threads still provide a solid foundation.

In the broader competitive field, the Ryzen 5 8400F's average benchmark score of 25,005 places it in close company with several rivals. The AMD Ryzen 5 7500F scores 24,964, a mere 0.2% difference, while the Intel Core i7-13620H sits at 24,911, just 0.4% behind. The AMD EPYC 9474F leads this comparison group at 25,103, edging out the 8400F by 0.4%. These margins are razor-thin, suggesting that CPU-level differences among similarly positioned processors are unlikely to be the deciding factor in Rust's frame rates.

What makes Rust particularly interesting is its combination of a large, persistent world with frequent physics calculations and entity updates. The benchmark results reflect this: at 1080p Ultra, this combo produces 117 FPS average, but at 4K Ultra, it falls to 47 FPS. That dramatic scaling curve tells a story about where the bottlenecks lie as resolution increases.

# GPU Role

The RTX 5070 Ti brings substantial graphical horsepower to Rust, with 16 GB of GDDR7 memory on a 256-bit bus delivering 896.0 GB/s of bandwidth. This memory configuration is particularly relevant for Rust, a game known for loading large texture sets across its procedurally generated environments. The 16 GB capacity ensures that texture streaming at high resolutions should not be constrained by VRAM limitations.

The GPU's clock behavior shows a base clock of 2295 MHz and a boost clock of 2452 MHz, with memory running at 1750 MHz (28 Gbps effective). These frequencies, combined with the 8960 shading units and 280 texture mapping units, give the card substantial raw compute throughput. The 43.94 TFLOPS of FP32 performance and 686.6 GTexel/s texture rate indicate the card can feed data to the display pipeline quickly under ideal conditions.

Looking at the measured FPS data, the GPU's influence becomes clear when examining the scaling from 1080p to 4K. At 1080p Low, the combo produces 216 FPS average—a very high number that suggests the CPU is keeping pace well. But at 4K Ultra, the average drops to 47 FPS. The gap between Low and Ultra settings at each resolution shows how much work the GPU is doing: at 1080p, Low produces 216 FPS while Ultra produces 117 FPS, a 99 FPS difference. At 4K, Low yields 110 FPS while Ultra yields 47 FPS, a 63 FPS difference.

The RTX 5070 Ti's percentile rank of 86 among all GPUs, with an average benchmark score of 49,957, places it in interesting company. The AMD Radeon RX 6900 XT scores 50,951, about 2% higher, while the RX 6800 XT scores 48,477, about 3.1% lower. The Intel Arc A550M trails by 0.4% with 49,737. These near-neighbor comparisons suggest the 5070 Ti is competitive with previous-generation high-end cards, though not dramatically ahead of them in raw benchmark terms.

# Resolution Scaling

The resolution scaling pattern in Rust reveals a system that shifts from CPU-bound at lower resolutions to GPU-bound at higher ones. At 1080p Low, the combo achieves 216 FPS—a figure so high that it likely approaches the CPU's practical limit for frame generation in Rust's simulation-heavy gameplay. The CPU's 6 cores at 4.20 GHz base and 4.70 GHz boost clock, with 16 MB of shared L3 cache, handle the game's single-threaded and lightly-threaded workloads competently at this resolution.

Moving from 1080p to 1440p at Low settings, the average FPS drops from 216 to 187, a decrease of 13.4%. At 4K Low, the average falls to 110 FPS, representing a 49.1% drop from 1080p. This scaling is gentler than what would be expected if the GPU were fully saturated at lower resolutions, reinforcing the interpretation that the CPU is the limiting factor at 1080p Low.

The picture changes dramatically at Ultra settings. At 1080p Ultra, the combo produces 117 FPS. At 1440p Ultra, it drops to 80 FPS, a 31.6% reduction. At 4K Ultra, it falls to 47 FPS, a 59.8% reduction from 1080p. This steeper scaling curve at Ultra settings indicates that the GPU becomes the primary constraint as both resolution and graphical fidelity increase. The RTX 5070 Ti's 16 GB VRAM and 896.0 GB/s bandwidth are being pushed hard by Rust's Ultra preset at 4K.

The Medium preset shows an intermediate pattern. At 1080p Medium, the combo produces 182 FPS with a minimum of 155 FPS and maximum of 209 FPS. At 1440p Medium, the average is 125 FPS with a range of 106 to 144 FPS. At 4K Medium, the average drops to 74 FPS with a range of 63 to 85 FPS. The minimum FPS numbers at Medium settings are particularly informative—they indicate that even in demanding moments, the system maintains playable frame rates at 1440p, with the 106 FPS minimum still comfortably above typical display refresh rates.

# CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, manufactured on a 4 nm process at TSMC. Its base clock of 4.20 GHz and boost clock of 4.70 GHz provide the single-thread performance that Rust's simulation-heavy gameplay requires. The CPU's 16 MB of shared L3 cache and 1 MB L2 cache per core help maintain data locality for the game's entity tracking and physics calculations.

Looking at the CPU's synthetic benchmark results, the multi-threaded scores are notable. The Cinebench R23 multi-core score of 20,851 and single-core score of 2,943 show balanced performance across both workloads. The 3DMark tests reveal a scaling pattern: 2-thread score of 1,874, 4-thread score of 3,563, 8-thread score of 5,275, and max-thread score of 6,165. The incremental gains from 8 to max threads are modest, suggesting the 6-core design reaches near-peak throughput with 8 threads, which is relevant for Rust's typically moderate thread utilization.

The PassMark results further characterize the CPU's capabilities. The multi-thread score of 24,389 and single-thread score of 3,685 indicate strong per-core performance. The integer math score of 74,021 and floating point math score of 46,217 show the CPU handles both types of calculations effectively. The data compression score of 288,158 and encryption score of 16,646 suggest the processor can manage the streaming and network-related tasks that Rust's online multiplayer requires.

The CPU's role in this combo becomes evident when examining the FPS scaling at Low settings. At 1080p Low, the system produces 216 FPS. At 1440p Low, it produces 187 FPS. At 4K Low, it produces 110 FPS. The relatively gentle decline from 1080p to 1440p at Low settings (13.4% drop) compared to the steeper decline from 1440p to 4K (41.2% drop) suggests that the CPU can feed the GPU efficiently at 1080p and 1440p, but the GPU becomes increasingly stressed at 4K even on Low settings.

The Ryzen 5 8400F's 77th percentile ranking among all CPUs, with an average benchmark score of 25,005, places it in a competitive position. Its nearest rivals all score within 0.4% of each other, indicating that this segment of the CPU market is tightly clustered. For Rust specifically, the CPU's 12 threads and high boost clock likely contribute to the system's ability to maintain high frame rates at lower resolutions where the GPU has spare capacity.

# Settings Recommendations

The measured FPS data provides clear guidance for optimizing the Rust experience with this combo. At 1080p, all settings presets produce playable frame rates, with even Ultra delivering 117 FPS. However, the jump from High to Ultra at 1080p costs 37 FPS (from 154 to 117), which may not be worth the visual gains for competitive play. Medium at 1080p offers 182 FPS with a minimum of 155 FPS, making it the best choice for high refresh rate monitors.

At 1440p, the Medium preset stands out as the sweet spot. The 125 FPS average with 106 FPS minimum ensures smooth gameplay even in demanding scenes, while the 144 FPS maximum shows the system can push higher when possible. High at 1440p produces 106 FPS, which is still playable but offers less headroom above 60 FPS. Ultra at 1440p drops to 80 FPS, which is acceptable for slower-paced survival gameplay but may feel less responsive in combat situations.

At 4K, the choices become more constrained. Medium produces 74 FPS with a minimum of 63 FPS, which is playable but close to the 60 FPS threshold. High drops to 62 FPS, and Ultra falls to 47 FPS, which is below the standard 60 FPS target. Low at 4K produces 110 FPS, but the visual quality sacrifice may be significant for a game like Rust where environmental detail helps with spotting enemies and resources.

For the best balance of visual quality and performance, the Medium preset at 1440p offers the most compelling experience. The 125 FPS average comfortably exceeds standard 60 Hz displays while also supporting 120 Hz and 144 Hz monitors. The 106 FPS minimum ensures that frame drops during intense moments, such as base raids or large group encounters, remain above the 60 FPS threshold. If higher visual fidelity is desired, High at 1440p at 106 FPS remains a viable alternative, though the minimum FPS data is not available for this preset.
