Rust

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 4060 delivers a generationally consistent performance profile in Rust, one that scales predictably with resolution and graphics presets. The measured data shows a system that is capable of high-refresh 1080p gaming, comfortable 1440p gaming at medium-to-high settings, and only marginal 4K performance at the lowest preset. Benchmark results indicate that the combination sits in the 55th percentile of all tested combos for this title, a position that reflects its balanced but not overpowering hardware pairing.

Measured FPS Breakdown

At 3840x2160 (4K), the RTX 4060 and Ryzen 5 8400F produce the following average frame rates: with Low settings, the system reaches 65.2 FPS; with Medium settings, it drops to 43.1 FPS; with High settings, it falls further to 37.4 FPS; and with Ultra settings, it bottoms out at 26.6 FPS. The data shows a steep cliff between Low and Medium, with a 22.1 FPS gap (from 65.2 to 43.1), indicating that the 8 GB VRAM and 128-bit memory bus are likely saturated once texture quality and draw distance scale upward. The spread from best to worst preset is 38.6 FPS, which is the largest across all resolutions tested.

Moving to 2560x1440, the performance picture improves substantially. At Low settings, the combo averages 110.8 FPS; at Medium, it manages 75.4 FPS; at High, it holds 65.2 FPS; and at Ultra, it drops to 47.2 FPS. The gap between Low and Medium is 35.4 FPS, but the more relevant transition for playability is between High and Ultra, where the system loses 18 FPS (from 65.2 to 47.2). Notably, the 1440p High result (65.2 FPS) exactly matches the 4K Low result (65.2 FPS), suggesting that the bottleneck shifts from memory bandwidth at 4K to raw shader throughput at 1440p.

At 1920x1080, the system shows its strongest performance. Low settings yield 162.7 FPS; Medium delivers 111.1 FPS; High produces 92.6 FPS; and Ultra still manages 70.6 FPS. The relative scaling from Low to Ultra shows a 92.1 FPS drop, but even the worst-case Ultra preset remains above the 60 FPS playability threshold. The 1080p data reveals that the CPU’s single-thread performance (Cinebench R23 single-core score of 2943) is sufficient to feed the GPU at high frame rates, with the 162.7 FPS Low result indicating no significant CPU limitation at that preset.

Best Settings per Resolution

For 3840x2160, the only preset that clears the 60 FPS playability threshold is Low, achieving an average of 65.2 FPS. The data shows that Medium (43.1 FPS), High (37.4 FPS), and Ultra (26.6 FPS) all fall short, making Low the sole viable option for 4K gaming.

At 2560x1440, the most demanding preset that stays at or above 60 FPS is High, with an average of 65.2 FPS. Medium (75.4 FPS) and Low (110.8 FPS) also clear the threshold, but High represents the best visual quality that maintains playability. Ultra at 47.2 FPS is not recommended for smooth gameplay.

For 1920x1080, the system can handle Ultra settings at 70.6 FPS, which is the highest preset tested and comfortably above the 60 FPS line. High (92.6 FPS), Medium (111.1 FPS), and Low (162.7 FPS) all exceed the threshold, but Ultra provides the maximum fidelity without dropping below playable frame rates.

How This Combo Ranks

The combo ranks 2055th out of 3723 tested configurations for Rust, placing it in the middle of the pack (roughly the 55th percentile). This rank reflects the RTX 4060’s position as a mid-range GPU (61st percentile among all GPUs) paired with a CPU that sits at the 77th percentile among all processors. The data suggests that the GPU is the limiting factor in this pairing, as the CPU’s percentile ranking is notably higher than the GPU’s.

In the context of Rust specifically, this rank means that the combo outperforms a majority of tested systems but is not near the top tier. The 4K Ultra result of 26.6 FPS and the 1440p Ultra result of 47.2 FPS indicate that this system is not designed for maximum fidelity at higher resolutions. Conversely, the 1080p results show that it can compete with more expensive configurations at lower resolutions, where the CPU’s strong single-thread performance (PassMark single-thread score of 3685) helps maintain high frame rates.

Similar Performance Alternatives

For the CPU, the nearest rivals by average benchmark score are all within a narrow band. The AMD Ryzen 5 7500F scores 24964, which is just 0.2% higher than the 8400F’s 25005 average. The Intel Core i7-11850H scores 24935 (0.3% lower), the Intel Core i7-13620H scores 24911 (0.4% lower), and the AMD EPYC 9474F scores 25103 (0.4% higher). These deltas are negligible in real-world gaming, so any of these processors would produce nearly identical frame rates in Rust when paired with the same GPU. The practical implication is that the 8400F’s Zen 4 architecture and 6-core/12-thread configuration are well-matched to the RTX 4060, and a system builder would see no meaningful difference by swapping among these CPUs.

For the GPU, the nearest rivals are less intuitive. The AMD Radeon HD 7790 scores 17666 in average benchmarks, just 0.2% higher than the RTX 4060’s 17639. The AMD Radeon 780M scores 17588 (0.3% lower), the AMD Radeon Pro 560 scores 17551 (0.5% lower), and the AMD Radeon Pro 460 scores 17509 (0.7% lower). These scores are aggregate numbers, and for Rust specifically, the RTX 4060’s Ada Lovelace architecture with 8 GB GDDR6 memory and 272.0 GB/s bandwidth will behave differently than these older or integrated alternatives. The data suggests that in synthetic benchmarks, the RTX 4060 is comparable to these GPUs, but in a real-time survival title like Rust, the 4060’s newer feature set and driver optimization likely provide a tangible advantage, even if the raw scores are similar.

CPU and GPU Roles

The scaling between resolutions and presets reveals the division of labor between the Ryzen 5 8400F and the RTX 4060. At 3840x2160, the frame rate drops by 58.9% from Low (65.2 FPS) to Ultra (26.6 FPS), a massive penalty that points to GPU-bound rendering. The 8 GB VRAM and 128-bit memory bus are overwhelmed by 4K textures and shading complexity, making the GPU the definitive bottleneck. The CPU’s role at 4K is minimal, as evidenced by the fact that even the lowest preset cannot push the GPU beyond 65.2 FPS.

At 2560x1440, the scaling is less severe but still GPU-dominant. The drop from Low (110.8 FPS) to Ultra (47.2 FPS) is 57.4%, and the High preset (65.2 FPS) matches the 4K Low result, reinforcing that the GPU is the limiting factor. The CPU’s 12 threads (with a Cinebench R23 multi-core score of 20851) are more than adequate for Rust’s simulation and physics at this resolution, as the frame rates remain high even at Low settings.

At 1920x1080, the balance shifts slightly. The Low preset (162.7 FPS) versus Ultra (70.6 FPS) shows a 56.6% drop, but the absolute numbers suggest that the CPU begins to matter more. The Ryzen 5 8400F’s single-thread performance (PassMark score of 3685) is sufficient to keep the GPU fed at Low settings, but at Ultra, the GPU’s shader load becomes the primary constraint. Data from the 3DMark tests shows the CPU scoring 951 in single-thread and 6165 in max-thread benchmarks, which places it well above the minimum requirements for Rust’s CPU-bound tasks. In summary, the GPU dominates performance across all resolutions, but the CPU’s strong single-core scores prevent it from becoming a bottleneck at 1080p.

The Verdict

This PC can run Rust, but the playable experience depends heavily on resolution and settings. At 1920x1080, the system clears the 60 FPS threshold at every preset, including Ultra at 70.6 FPS, making it fully capable of smooth gameplay with maximum visual quality. At 2560x1440, the system is playable at Low (110.8 FPS), Medium (75.4 FPS), and High (65.2 FPS), but Ultra falls below the threshold at 47.2 FPS. For 1440p users, High settings are the sweet spot for the best balance of fidelity and performance.

At 3840x2160, the system is only playable at Low settings, with 65.2 FPS. Any higher preset (Medium at 43.1 FPS, High at 37.4 FPS, Ultra at 26.6 FPS) fails to reach 60 FPS, meaning 4K gaming requires significant compromises. The verdict is clear: this combo is a solid 1080p machine, a good 1440p machine with settings adjustments, and a marginal 4K machine limited to Low presets.
