Rust

The AMD Ryzen 5 8400F and AMD Radeon RX 7700 XT combination delivers a highly playable Rust experience across most settings, though the data reveals a clear performance ceiling at higher resolutions. The benchmark results, measured across three resolutions and four quality presets, show a system that is well-balanced at 1080p but increasingly GPU-bound as pixel count rises.

Resolution Scaling

The measured frame rates show a predictable decline as resolution increases from 1920x1080 to 3840x2160, but the magnitude of that drop varies significantly by preset. At Low settings, the transition from 1080p to 1440p sees average FPS fall from 187.2 to 128.7, a reduction of 58.5 frames. Pushing further to 4K drops the average to 74.8, meaning the Low preset loses over 60% of its 1080p performance when scaled to 4K.

High settings follow a similar pattern with slightly smaller absolute losses. The 109.2 FPS average at 1080p falls to 70.6 at 1440p and then to 41.2 at 4K. This scaling behavior indicates that Rust becomes heavily pixel-bound at higher resolutions, with the RX 7700 XT's rendering throughput being the primary constraint. The gap between 1440p and 4K is particularly pronounced on the Ultra preset, where the 53.3 FPS average at 1440p drops to just 32.3 at 4K.

The resolution scaling data suggests that the CPU is not the limiting factor in most configurations. At 1080p Low, the system achieves 187.2 FPS, which is a strong indicator that the Ryzen 5 8400F's six cores and twelve threads are keeping pace with the GPU's output. However, the steep drop-off at 4K across all presets points to the GPU's 192-bit memory bus and 432.0 GB/s bandwidth becoming a bottleneck when rendering at higher pixel counts.

How This Combo Ranks

Within the database of tested combinations, this pairing of the Ryzen 5 8400F and RX 7700 XT achieves a combo rank of 752 out of 1717 total combos for Rust. This places the system in the upper-middle tier of all tested configurations, meaning roughly 56% of tested combos deliver higher average frame rates in this game.

The rank reflects a system that is competent but not exceptional for Rust. The CPU's percentileVsAllCpus score of 82 indicates it outperforms 82% of all tested processors, while the GPU's percentileVsAllGpus score of 73 shows it beats 73% of tested graphics cards. The combination of two above-average components yields a result that is solidly competitive, though the gap between the CPU's higher percentile and the GPU's lower one hints that the graphics card is the more limiting factor in this pairing.

Compared to the GPU's nearest rivals, the RX 7700 XT sits within a tight performance band. The NVIDIA GeForce RTX 5060 scores 30109 on average, essentially identical to the RX 7700 XT's 30097, with a deltaPct of 0. The AMD Radeon RX 570 scores 30158, a 0.2% lead, while the NVIDIA Tesla M60 trails by 0.4%. These near-identical average scores suggest that the RX 7700 XT is positioned in a crowded performance tier where small differences in synthetic benchmarks translate to minimal real-world deltas.

GPU Role

The Radeon RX 7700 XT, built on the RDNA 3.0 architecture with the Navi 32 chip, provides 12 GB of GDDR6 memory across a 192-bit bus. This memory configuration delivers 432.0 GB/s of bandwidth, which becomes a critical factor in Rust's open-world environments where texture streaming and large draw distances place significant demands on memory throughput.

The GPU's clock behavior shows a base clock of 1435 MHz and a boost clock of 2544 MHz, with a game clock of 2171 MHz. The 35.17 TFLOPS of FP32 compute power is substantial for a mid-range card, and the 96 ROPs handle pixel output at a rate of 244.2 GPixel/s. These specifications translate to strong 1080p performance, where the card achieves 187.2 FPS on Low settings and 109.2 FPS on High.

At 4K, the GPU's limitations become apparent. The 12 GB frame buffer is adequate for Rust's current asset quality, but the 192-bit memory bus constrains bandwidth exactly when higher resolutions demand more data movement. The measured 4K results, ranging from 32.3 FPS on Ultra to 74.8 FPS on Low, show that the card can handle 4K only at reduced quality settings. The 73rd percentile standing versus all GPUs confirms this is a mid-tier performer, not a high-end 4K solution.

Measured FPS Breakdown

At 1920x1080, the system delivers its strongest results across all presets. The Low setting produces an average of 187.2 FPS, which drops to 127.4 on Medium and 109.2 on High. The Ultra preset yields 80.5 FPS, still comfortably above the 60 FPS threshold for smooth gameplay. The spread from Low to Ultra at 1080p is 106.7 FPS, showing that the GPU has substantial headroom even at maximum quality.

Moving to 2560x1440, the averages compress somewhat. Low delivers 128.7 FPS, Medium drops to 84.8, High comes in at 70.6, and Ultra manages 53.3. The 1440p results show a tighter grouping between Medium and High, with just a 14.2 FPS difference, suggesting that the GPU's shading units are becoming the limiting factor rather than memory bandwidth.

At 3840x2160, the performance curve flattens further. Low produces 74.8 FPS, Medium falls to 49, High reaches 41.2, and Ultra bottoms out at 32.3. The gap between Low and Ultra at 4K is 42.5 FPS, much narrower than at 1080p. This compression indicates that at 4K, every preset is constrained by the same fundamental GPU limitation, likely pixel throughput or memory bandwidth. The 4K Ultra result of 32.3 FPS falls below the generally accepted 60 FPS playability threshold, while even 4K Medium at 49 FPS requires compromises.

CPU Role

The Ryzen 5 8400F, based on the Zen 4 architecture in the Phoenix codename, provides six cores and twelve threads with a base clock of 4.20 GHz and a boost clock of 4.70 GHz. This 8000 series processor is manufactured on TSMC's 4 nm process, offering 25,000 million transistors in a 178 mm² die. The 16 MB of shared L3 cache and 1 MB L2 per core provide sufficient cache capacity for Rust's simulation-heavy gameplay.

Single-threaded performance is strong, as evidenced by the 3dmark_single_thread score of 951 and the cinebench_r23_singlecore score of 2943. The passmark_single_thread score of 3684 places this CPU in the 82nd percentile versus all CPUs, indicating it handles Rust's primary game thread well. Multi-threaded performance is also respectable, with cinebench_r23_multicore scoring 20851 and 3dmark_max_threads reaching 6165.

The CPU's nearest rival, the AMD Ryzen 7 2700X, scores 25057 on average, matching the 8400F's 25064 with a deltaPct of 0. The AMD Ryzen 5 7500F sits 0.3% behind, while the AMD Ryzen AI 5 PRO 340 trails by 0.1%. This tight grouping shows that the 8400F is positioned at the edge of a performance plateau where additional cores or clock speed yield diminishing returns in Rust's current implementation.

At 1080p with Low settings, the 187.2 FPS result shows the CPU is not bottlenecking the GPU. However, the fact that 1080p High produces 109.2 FPS while 1440p High produces 70.6 FPS indicates the GPU becomes the primary constraint as resolution increases. The CPU's contribution is most visible in the consistency of frame delivery, where its 4.70 GHz boost clock helps maintain stable performance in complex scenes.

Settings Recommendations

For players targeting 1920x1080, the High preset at 109.2 FPS offers the best balance of visual quality and performance. The Ultra preset at 80.5 FPS is also viable and provides the maximum visual fidelity while remaining well above 60 FPS. The Medium preset at 127.4 FPS is unnecessary at this resolution since High achieves nearly the same smoothness with better visuals.

At 2560x1440, the High preset at 70.6 FPS is the recommended choice, providing a comfortable margin above 60 FPS while maintaining good visual quality. The Medium preset at 84.8 FPS is a reasonable alternative for players who prioritize frame rate over fidelity. The Ultra preset at 53.3 FPS dips below the 60 FPS threshold and should only be considered by players who value maximum visuals and can tolerate occasional frame drops.

For 3840x2160, the Low preset at 74.8 FPS is the only truly playable option, delivering smooth performance at the cost of visual quality. The Medium preset at 49 FPS is borderline, suitable for players who prefer quality over smoothness but may notice stuttering during intense scenes. The High and Ultra presets at 41.2 and 32.3 FPS respectively are not recommended for competitive play, though they remain usable for exploration-focused gameplay where frame rate is less critical.

Across all resolutions, the data indicates that the High preset offers the most consistent experience relative to its visual impact. The 4K results show that this component pairing is best utilized at 1080p or 1440p, where the RX 7700 XT can leverage its full capabilities without being constrained by memory bandwidth limitations.
