The following sections break down the CPU and GPU roles, resolution scaling behavior, and provide specific settings recommendations.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, built on a 4 nm process. It operates with a base clock of 4.20 GHz and a boost clock of 4.70 GHz, with a 65 W TDP. The CPU has a 16 MB shared L3 cache and 1 MB of L2 cache per core, along with 64 KB of L1 per core. Memory support is DDR5 with dual-channel configuration, providing 83.2 GB/s of bandwidth.

In synthetic benchmarks, this CPU achieves a Cinebench R23 multicore score of 20851 and a single-core score of 2943. Its PassMark multithread score is 24389, with a single-thread score of 3685. The 3DMark 16-thread test yields a score of 6091, while the 2-thread test scores 1874. The 4-thread and 8-thread tests produce scores of 3563 and 5275 respectively. Max-thread performance reaches 6165, and single-thread 3DMark score is 951. The CPU's average benchmark score is 25005, placing it in the 77th percentile of all CPUs.

Comparing to its nearest rivals, the Ryzen 5 8400F is within 0.4% of the Intel Core i7-13620H, which scores 24911 (a 0.4% delta). It is 0.3% ahead of the Intel Core i7-11850H (24935) and 0.2% ahead of the AMD Ryzen 5 7500F (24964). The AMD EPYC 9474F scores 25103, which is 0.4% higher than the 8400F. These deltas are negligible in practical terms, indicating that the 8400F performs essentially on par with these alternatives in aggregate CPU benchmarks.

For Rust specifically, the measured FPS data shows that at 1080p with Low settings, the system achieves 118 FPS average. This suggests that at lower settings and resolutions, the CPU is capable of feeding the GPU adequately. The CPU's 6 cores and 12 threads are sufficient for Rust's simulation and entity processing, which typically benefits from strong single-thread performance. The single-core Cinebench R23 score of 2943 and PassMark single-thread score of 3685 indicate decent per-core performance, though not top-tier.

The CPU's benchmark percentile of 77 means it outperforms 77% of all CPUs in the database. However, in Rust, the bottleneck shifts to the GPU at higher resolutions and settings, as evidenced by the FPS scaling. At 1080p Low, the system produces 118 FPS, but at 4K Ultra, it drops to 21 FPS, showing that the CPU is not the primary limiting factor at high resolutions. The data suggests that the Ryzen 5 8400F provides adequate processing power for Rust, but its mid-range positioning means it won't push extreme frame rates in CPU-heavy scenarios.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B570 is based on the Xe2-HPG architecture (Battlemage generation) and uses the BMG-G21 chip, fabricated on a 5 nm process. It features 2304 shading units, 144 texture mapping units, and 80 raster operation pipelines. The GPU has 18 ray tracing cores and operates at a fixed clock speed of 2500 MHz for both base and boost. Memory consists of 10 GB of GDDR6 on a 160-bit bus, providing 380.0 GB/s of bandwidth. The memory clock is 2375 MHz with 19 Gbps effective speed.

In synthetic benchmarks, the Arc B570 achieves a PassMark G3D score of 14195 and a PassMark GPU Compute score of 7281. The 3DMark Steel Nomad DX12 test yields a score of 2649. Geekbench OpenCL and Vulkan scores are 83514 and 96844 respectively. Older DirectX tests show scores of 164 for DirectX 9, 118 for DirectX 11, and 72 for DirectX 12. The GPU's average benchmark score is 20556, placing it in the 65th percentile of all GPUs.

The nearest rivals show the Arc B570 is closely matched with the NVIDIA GeForce RTX 3070 Mobile, which scores 20534 (a 0.1% delta). The Intel Arc A750 scores 20582, which is 0.1% higher. The NVIDIA Quadro M4000M scores 20480 (0.4% lower) and the AMD Radeon R9 M390X scores 20662 (0.5% higher). These deltas are all within 0.5%, indicating that the B570 performs in the same class as these GPUs in aggregate benchmarks.

For Rust, the GPU's 10 GB of VRAM is relevant for texture loading and draw distances. The measured FPS at 1080p Medium shows an average of 79 FPS with a minimum of 67 and maximum of 91, which is a playable range. The GPU's bandwidth of 380.0 GB/s is moderate, and the 160-bit bus width limits memory throughput compared to wider-bus cards. At 1440p Medium, the average drops to 54 FPS, and at 4K Medium to 32 FPS, showing the GPU becoming the bottleneck as resolution increases.

The GPU's pixel rate of 200.0 GPixel/s and texture rate of 360.0 GTexel/s are modest figures. The FP32 performance of 11.52 TFLOPS places it in the mid-range category. In Rust, which can be demanding on fill rate and memory bandwidth, the B570 shows it can handle 1080p well but struggles at 4K, where the average FPS at High settings is only 27. The 10 GB VRAM is sufficient for Rust at most settings, as the game's textures are not excessively demanding, but the overall GPU throughput limits high-resolution performance.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured data shows a clear pattern of FPS degradation as resolution increases. At 1080p Low, the system achieves 118 FPS. Moving to 1440p Low drops this to 81 FPS, a reduction of 31%. At 4K Low, the average is 48 FPS, which is 59% lower than 1080p. This scaling indicates that the GPU is the limiting factor even at Low settings, as the CPU should be able to maintain higher frame rates at lower resolutions.

For Medium settings, the progression is 79 FPS at 1080p, 54 FPS at 1440p (32% drop), and 32 FPS at 4K (59% drop from 1080p). The High settings show 67 FPS at 1080p, 46 FPS at 1440p (31% drop), and 27 FPS at 4K (60% drop). Ultra settings follow the same pattern: 51 FPS at 1080p, 35 FPS at 1440p (31% drop), and 21 FPS at 4K (59% drop from 1080p).

The consistent ~31% drop from 1080p to 1440p and ~59-60% drop from 1080p to 4K across all settings suggests that the GPU is the primary bottleneck. If the CPU were the limiting factor, we would expect the FPS to remain relatively flat across resolutions at lower settings. Instead, the FPS drops proportionally with the pixel count increase, which is characteristic of a GPU-bound scenario.

The Arc B570's performance at 4K is particularly weak, with the best 4K result being 48 FPS at Low settings. At 4K Medium, the average drops to 32 FPS, and at High it's 27 FPS. These numbers are below the 60 FPS target for smooth gameplay. The GPU's 160-bit memory bus and 10 GB VRAM are likely contributors to this poor 4K scaling, as higher resolutions demand more memory bandwidth and capacity.

At 1080p, the system is more balanced. The 118 FPS at Low settings shows the CPU can handle the game's logic, while the GPU can render frames quickly at this resolution. The 67 FPS at 1080p High is playable, and the 51 FPS at Ultra is borderline but acceptable for a game like Rust. The resolution scaling data clearly indicates that for this combo, 1080p is the sweet spot, with 1440p being playable at lower settings, and 4K being impractical for smooth gameplay.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the best experience for this combination of AMD Ryzen 5 8400F and Intel Arc B570 depends on the target resolution and acceptable frame rate. For 1080p, the Low preset delivers 118 FPS average, which is excellent for competitive play or high refresh rate monitors. The Medium preset at 79 FPS is also very good, providing a balance between visual quality and performance. The High preset at 67 FPS is perfectly playable and offers better visuals. The Ultra preset at 51 FPS is the most demanding option, and while it's technically playable, the lower frame rate may be noticeable in fast-paced situations.

For 1440p, the Low preset at 81 FPS is the only option that exceeds 60 FPS. The Medium preset at 54 FPS is acceptable but not ideal for competitive play. The High preset at 46 FPS and Ultra at 35 FPS are below the 60 FPS threshold and may feel less responsive. For 1440p users, the Low preset is recommended for the best performance, with Medium being a compromise for better visuals.

At 4K, none of the presets achieve 60 FPS. The Low preset at 48 FPS is the best performer, followed by Medium at 32 FPS, High at 27 FPS, and Ultra at 21 FPS. For 4K gaming, the Low preset is the only reasonable choice, and even then, the frame rate is below what most gamers would consider smooth. Given these numbers, 4K is not recommended for this combo unless the user is willing to accept significant performance compromises.

The best overall experience per the measured rows is the Medium preset at 1080p, which provides 79 FPS average with a minimum of 67 FPS and maximum of 91 FPS. This offers a good balance of visual quality and performance, with the minimum FPS staying above 60. The High preset at 1080p (67 FPS) is also a strong choice for those prioritizing visuals. For players with 1440p monitors, the Low preset at 81 FPS is the recommended starting point, with the option to try Medium if the frame rate feels acceptable.
