Rust

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 3070 Ti combination delivers a wide performance envelope across Rust’s three tested resolutions. At 1080p, the pair averages 196.8 FPS on Low settings, while 4K Ultra drops to 31.8 FPS. The data indicates a system that can handle competitive play at 1080p and 1440p with ease, but it requires careful settings management for 4K displays.

Best Settings per Resolution

At 3840x2160, the highest preset that maintains an average at or above the 60 FPS threshold is Low, which produces an average of 78.2 FPS. The Medium preset falls below the mark at 51.3 FPS, making Low the only viable option for 4K gaming. This leaves significant visual fidelity on the table, but the frame rate headroom is substantial.

For 2560x1440, the combination achieves playable frame rates across all four presets. The most demanding preset that clears 60 FPS is Ultra, with an average of 60.5 FPS. This is a razor-thin margin — only 0.5 FPS above the threshold — but it confirms that the hardware can handle maximum settings at this resolution without dipping below the playable line.

At 1920x1080, the story is similar but with more comfort. The Ultra preset averages 81.3 FPS, which is 21.3 FPS above the threshold. This represents the best balance of visual quality and performance for the resolution, as all four presets (Low, Medium, High, Ultra) exceed 60 FPS.

CPU and GPU Roles

The performance scaling across resolutions reveals a system that becomes increasingly GPU-bound as resolution rises. At 1080p Low, the average of 196.8 FPS demonstrates that the Ryzen 5 8400F can feed the RTX 3070 Ti effectively, but the GPU is likely the limiting factor even at this low preset. Moving from 1080p Low to 1440p Low, the frame rate drops to 134.4 FPS — a 31.7% reduction — which aligns with the GPU’s rendering workload increasing by roughly 78% in pixel count. The CPU’s 12 threads and 16 MB of L3 cache appear sufficient for Rust’s simulation and entity processing at these settings.

At 4K, the GPU’s role becomes dominant. The drop from 1440p Ultra (60.5 FPS) to 4K Ultra (31.8 FPS) represents a 47.4% performance loss, which is disproportionate to the 77.8% pixel increase, suggesting that the RTX 3070 Ti’s 8 GB of GDDR6X memory and 608.3 GB/s bandwidth are becoming limiting factors. The GPU’s 21.75 TFLOPS of FP32 compute is being saturated at 4K, while the CPU’s workload remains relatively constant.

The preset scaling at each resolution further clarifies the bottleneck. At 1080p, moving from Low to Ultra reduces average FPS from 196.8 to 81.3 — a 58.7% drop. This is a larger relative change than at 4K, where Low to Ultra goes from 78.2 to 31.8 FPS, a 59.3% drop but from a lower base. The similarity in percentage drops suggests that the GPU is the primary constraint across all resolutions, with the CPU consistently capable of keeping up.

Similar Performance Alternatives

The nearestRivals data for the CPU and GPU provides context for what other hardware would behave similarly. The AMD Ryzen 5 8400F has an average benchmark score of 25005, placing it just 0.2% above the AMD Ryzen 5 7500F (24964) and 0.3% above the Intel Core i7-11850H (24935). The Intel Core i7-13620H (24911) is 0.4% slower, while the AMD EPYC 9474F (25103) is 0.4% faster. For gaming purposes, these differences are negligible — all five processors would deliver nearly identical frame rates in Rust when paired with the same GPU.

On the graphics side, the RTX 3070 Ti’s average benchmark score of 29945 is within 0.5% of the NVIDIA GeForce RTX 2080 Ti (29783) and 0.1% of the NVIDIA GeForce RTX 5070 Mobile (29928). The AMD Radeon RX 6800 (30095) is 0.5% faster, and the AMD Radeon RX 6700 (30433) is 1.6% faster. Users with any of these GPUs can expect comparable performance in Rust, with the RX 6700 potentially offering a slight edge in GPU-bound scenarios at 4K.

The Verdict

This PC can run Rust, but the playable experience depends heavily on resolution. At 1920x1080, the system clears the 60 FPS threshold on all four presets, with Ultra averaging 81.3 FPS. This is the sweet spot for this combination. At 2560x1440, all presets also clear 60 FPS, but Ultra’s 60.5 FPS average leaves no headroom for demanding scenes or multiplayer raids. The 3840x2160 resolution is only playable on Low settings, which average 78.2 FPS; Medium at 51.3 FPS and High at 44.4 FPS are below the playable threshold.

The verdictByResolution data confirms that the system is a capable 1440p machine and an excellent 1080p performer. For 4K, users must accept Low settings or consider the RTX 3070 Ti’s 8 GB memory as a fundamental limitation. The percentileVsAllGpus of 75 and percentileVsAllCpus of 77 indicate that both components sit in the upper quartile of all hardware, which aligns with the observed performance.

FAQ

Q: Can this combination run Rust at 60 FPS on 4K Ultra settings?

How This Combo Ranks

The comboRankInGame places this configuration at rank 1306 out of 3723 tested combinations. This puts the system in the 65th percentile of all tested combos, which is a solid mid-to-upper tier placement. The rank reflects the balanced nature of the pairing — the CPU’s 77th percentile and GPU’s 75th percentile scores combine to produce a system that handles Rust’s demands competently but does not dominate the top of the chart.

The rank of 1306 out of 3723 means there are 2417 tested combinations that perform worse, and 1305 that perform better. This places the system in the top third of all tested hardware, which is consistent with the measured frame rates showing 60+ FPS at 1440p Ultra and 1080p Ultra. The ranking suggests that while this combo is not a top-tier 4K machine, it outperforms a majority of systems for Rust specifically.

The data shows a consistent pattern: each step up in resolution at the same preset reduces average FPS by roughly 40-50%. At 1080p Low, the system achieves 196.8 FPS; at 1440p Low, 134.4 FPS; and at 4K Low, 78.2 FPS. This scaling is typical of a GPU-bound workload where the RTX 3070 Ti’s 608.3 GB/s memory bandwidth and 21.75 TFLOPS compute are progressively saturated. The 8 GB VRAM capacity also becomes a factor at 4K, where texture and buffer demands may exceed available memory, contributing to the steep drop between 1440p Ultra and 4K Ultra.

The Ryzen 5 8400F’s performance holds up well across all presets. Its 12 threads and 4.70 GHz boost clock ensure that Rust’s simulation and entity update loops are never starved, even when the GPU is rendering at maximum settings. The CPU’s 77th percentile ranking and benchmark scores (e.g., 20851 in Cinebench R23 multicore) indicate substantial headroom for Rust’s single-threaded and multi-threaded workloads. The system’s overall behavior suggests a well-balanced build where the GPU is the limiting factor at every resolution, but the CPU never drags performance down.
