Rust

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 3080 Ti pairing delivers a robust Rust experience, with benchmark data showing that 1080p and 1440p play is consistently smooth across all tested presets, while 4K requires a settings compromise. The measured performance places this combo in the 896th position out of 3723 tested CPU-GPU combinations, indicating strong overall capability for this survival title. The data shows a clear pattern of GPU dominance at higher resolutions, but at 1080p the CPU's six Zen 4 cores prove sufficient to keep frame rates well above the playable threshold.

FAQ

Q: What is the highest preset this system can run at 4K while maintaining 60 FPS?

A: At 3840x2160, the Medium preset is the highest playable option, with an average of 61.8 FPS. The High preset drops to 52.7 FPS, and Ultra falls to 37.8 FPS, both below the 60 FPS threshold.

Q: Does the RTX 3080 Ti bottleneck the Ryzen 5 8400F at 1080p?

A: No. At 1920x1080, the Low preset yields 218 FPS and Ultra delivers 99.3 FPS, indicating the CPU keeps pace with the GPU even at lower resolutions where CPU load is typically higher.

Q: How does the Ryzen 5 8400F compare to its closest rival, the Ryzen 5 7500F?

A: The 8400F has an average benchmark score of 25005, which is 0.2% higher than the Ryzen 5 7500F's 24964 score. The performance difference is negligible, making them effectively equivalent.

Q: Is the RTX 3080 Ti a better performer than the RTX 5070 in this context?

A: Yes. The RTX 3080 Ti has an average benchmark score of 41187, which is 2% higher than the RTX 5070's 40377 score. The 3080 Ti also sits at the 83rd percentile among all GPUs.

Q: What frame rate can be expected at 1440p High settings?

A: At 2560x1440 with High settings, the system averages 85.9 FPS. This is comfortably above the 60 FPS playable threshold, with room for higher presets.

Q: Which resolution offers the most headroom for future settings increases?

A: 1920x1080 provides the most headroom, with the Ultra preset running at 99.3 FPS. This leaves 39.3 FPS of margin above the playable threshold, allowing for potential future patches or background tasks.

CPU and GPU Roles

The benchmark data reveals how the balance between the Ryzen 5 8400F and RTX 3080 Ti shifts across resolutions. At 1920x1080, the CPU plays a more significant role, as evidenced by the scaling from Low to Ultra: the average frame rate drops from 218 FPS to 99.3 FPS, a reduction of 54.4%. This wide spread indicates that the CPU can feed the GPU at lower settings, but the GPU becomes the limiting factor as graphical load increases.

Moving to 2560x1440, the GPU's influence grows. The Low preset averages 155.2 FPS, while Ultra maintains 65 FPS. The gap between Low and Ultra narrows to 58.1%, showing that the RTX 3080 Ti's 12 GB of GDDR6X memory and 912.4 GB/s bandwidth are increasingly taxed at this resolution. The 1440p Ultra result of 65 FPS sits just above the playable threshold, suggesting the GPU is near its limit for this title at maximum settings.

At 3840x2160, the GPU becomes the dominant factor. The Low preset averages 88.7 FPS, but Ultra plummets to 37.8 FPS. This 57.4% drop from Low to Ultra demonstrates that the RTX 3080 Ti's 34.10 TFLOPS of FP32 performance is the primary constraint. The CPU's role diminishes significantly, as the 8400F's 6 cores and 12 threads are sufficient to keep up with the GPU's output at all 4K presets. The data indicates that the RTX 3080 Ti is the performance ceiling at 4K, while the Ryzen 5 8400F provides adequate headroom at lower resolutions.

Measured FPS Breakdown

1920x1080: The system excels at this resolution across all settings. Low settings produce an average of 218 FPS, while Medium drops to 152.3 FPS. High settings deliver 125.2 FPS, and Ultra maintains 99.3 FPS. Every preset clears the 60 FPS threshold by a substantial margin, with even the most demanding Ultra setting offering 65.5% more FPS than required for smooth play.

2560x1440: Performance remains strong, though the margins narrow. Low averages 155.2 FPS, Medium hits 104.4 FPS, and High delivers 85.9 FPS. Ultra settings yield 65 FPS, which is 8.3% above the playable threshold. The progression from Low to Ultra shows a consistent 42-45 FPS drop between each successive preset, indicating balanced scaling.

3840x2160: This resolution tests the system's limits. Low produces a playable 88.7 FPS, Medium drops to 61.8 FPS, and High falls below the threshold at 52.7 FPS. Ultra is the most demanding, averaging just 37.8 FPS. The gap between Medium and High is 9.1 FPS, while the jump from High to Ultra costs 14.9 FPS, showing steep penalties for the highest quality settings.

The data shows no min or max FPS values recorded, meaning only average frame rates are available for analysis. The absence of these metrics limits insight into frame time consistency, but the average figures alone demonstrate that 1080p and 1440p play are viable at any preset, while 4K requires Medium or lower.

The Verdict

This PC can run Rust, but the experience varies significantly by resolution. At 1920x1080, all four presets are playable, with Ultra hitting 99.3 FPS and Low reaching 218 FPS. The verdictByResolution data confirms that 1080p offers the most comfortable margin, with the best playable setting being Ultra at 99.3 FPS.

At 2560x1440, every preset also clears the 60 FPS threshold. The best setting is Ultra at 65 FPS, which provides a slim but sufficient 8.3% buffer above the playable threshold. For users prioritizing visual quality, 1440p Ultra is viable, though frame rates will hover near the boundary.

At 3840x2160, only Low and Medium are playable. The best setting is Medium at 61.8 FPS, which is just 3% above the threshold. High and Ultra are not recommended, as they average 52.7 FPS and 37.8 FPS respectively. The data indicates that 4K gaming requires a settings trade-off, with Medium offering the highest quality that still maintains playable performance.

Overall, the system is well-suited for 1080p and 1440p gaming, with 4K possible only at reduced settings. The RTX 3080 Ti's 12 GB of memory and the Ryzen 5 8400F's Zen 4 architecture combine to deliver a capable Rust experience for most usage scenarios.

Similar Performance Alternatives

For the CPU, the Ryzen 5 8400F's nearest rivals show that several processors deliver nearly identical performance. The AMD Ryzen 5 7500F scores 24964, just 0.2% lower than the 8400F's 25005. The Intel Core i7-11850H and Core i7-13620H follow closely at 24935 and 24911, representing 0.3% and 0.4% deficits respectively. On the higher end, the AMD EPYC 9474F scores 25103, a 0.4% advantage over the 8400F. These rivals would behave almost identically in Rust, with differences well within measurement noise.

For the GPU, the RTX 3080 Ti's nearestRivals include some unexpected entries. The AMD Radeon Pro 5300 scores 40870, which is 0.8% lower than the 3080 Ti's 41187. The NVIDIA Tesla M40 24 GB and Tesla M40 score 41707 and 41897, representing 1.2% and 1.7% advantages respectively. The NVIDIA GeForce RTX 5070 scores 40377, a 2% deficit. These comparisons suggest that while the 3080 Ti is positioned at the 83rd percentile, several workstation and professional cards offer comparable raw compute performance, though gaming-specific features like ray tracing and DLSS are not accounted for in these scores.

In practical terms, a system with a Ryzen 5 7500F or Core i7-13620H would produce nearly identical frame rates in Rust, as would a GPU like the RTX 5070. The differences between these alternatives are below 2%, meaning users would not perceive a meaningful performance gap in gameplay.

How This Combo Ranks

The Ryzen 5 8400F and RTX 3080 Ti combination ranks 896th out of 3723 tested CPU-GPU pairings in Rust. This places the combo in the top 24.1% of all configurations, indicating strong but not elite performance. The rank reflects the balanced nature of this pairing, where the CPU's 77th percentile standing among all CPUs and the GPU's 83rd percentile among all GPUs combine to produce a system that handles Rust well at mainstream resolutions.

The ranking suggests that while this combo is far from the fastest available, it outperforms roughly three-quarters of tested configurations. This is consistent with the measured FPS data, which shows excellent 1080p performance, solid 1440p capability, and acceptable 4K results at lower presets. The 896th rank positions this system as a strong mid-to-high tier option for Rust, capable of delivering smooth gameplay for most players without requiring the absolute top-tier hardware.
