Rust

Measured Rust data for the AMD Ryzen 5 8400F paired with the AMD Radeon RX 5700 XT spans 1080p, 1440p, and 4K across Low, Medium, High, and Ultra presets. The highest average in the dataset is 134.1 fps at 1080p Low, and the lowest is 22.7 fps at 4K Ultra. This pairing combines a 6-core Zen 4 CPU with an RDNA 1.0 GPU, and the measured results show how the configuration scales as resolution and quality rise.

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

At 1080p, the average FPS ranges from 134.1 at Low to 89.6 at Medium, 75.2 at High, and 61.4 at Ultra. At 1440p, the same preset order is 90.6, 64.1, 54.3, and 42.2. At 4K, the averages are 52.7 at Low, 39.1 at Medium, 28.9 at High, and 22.7 at Ultra. The decline from 1080p to 4K is steep for every preset. High settings, for example, drop from 75.2 at 1080p to 54.3 at 1440p and then to 28.9 at 4K. Low settings drop from 134.1 to 90.6 and then to 52.7. This pattern indicates the GPU takes on a growing share of the load as pixel count increases; the CPU cannot compensate for the larger rendering workload.

The dataset contains only average FPS values, with minFps and maxFps fields null, so this analysis does not address frame-time stability. The quality preset also has a strong effect at each resolution. At 4K, Low produces 52.7 fps while Ultra produces 22.7 fps. At 1080p, 1440p Medium at 64.1 fps is higher than 1080p Ultra at 61.4 fps, showing that preset and resolution trade-offs can be used to keep the frame rate within a similar range. The limiting component at the top of the resolution scale is the Radeon RX 5700 XT, not the Ryzen 5 8400F.

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

The Radeon RX 5700 XT is a Navi 10 GPU with RDNA 1.0 architecture, built on a 7 nm process at TSMC. It uses 8 GB of GDDR6 memory on a 256-bit bus, with a bandwidth of 448.0 GB/s, a memory clock of 1750 MHz, and an effective data rate of 14 Gbps. The GPU has a base clock of 1605 MHz, a game clock of 1755 MHz, and a boost clock of 1905 MHz. Its compute configuration includes 2560 shading units, 160 texture units, and 64 ROPs, with a pixel rate of 121.9 GPixel/s and a texture rate of 304.8 GTexel/s. FP32 throughput is 9.754 TFLOPS, and the card is rated at 225 W TDP, connecting over PCIe 4.0 x16.

These specifications produce the measured Rust results. At 1080p, the card delivers 134.1 fps at Low and 61.4 at Ultra. At 1440p, it delivers 90.6 at Low and 42.2 at Ultra. At 4K, it delivers 52.7 at Low and 22.7 at Ultra. The 8 GB frame buffer is present across every measured preset, and the FPS progression is smooth rather than showing a sudden collapse, suggesting the memory configuration is not the limiting factor in this dataset. The GPU's average benchmark score is 24731, placing it in the 68th percentile of all GPUs. The nearest rivals are the NVIDIA RTX A5000 Mobile with a deltaPct of -0.1, the Intel Arc A350M at 0.3, the NVIDIA GeForce RTX 5060 Mobile at 0.6, and the NVIDIA Quadro RTX 5000 at 0.9. These synthetic scores are nearly tied, so the Rust results here differentiate the card in actual gameplay.

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

The Ryzen 5 8400F is a 6-core, 12-thread Zen 4 desktop processor on AMD Socket AM5, built at TSMC on a 4 nm process. It runs at 4.20 GHz base and 4.70 GHz boost, with a 16 MB L3 cache and a 65W TDP. The platform uses DDR5 in dual-channel mode, giving 83.2 GB/s of memory bandwidth, and provides PCIe Gen 4 with 20 CPU lanes. In synthetic benchmarks, the CPU scores 20851 in Cinebench R23 multi-core, 2943 in single-core, 24530 in Passmark multi-thread, and 3684 in Passmark single-thread. Its average benchmark score is 25064, placing it in the 82nd percentile of all CPUs. The nearest CPU rivals are the AMD Ryzen 7 2700X with a deltaPct of 0, the AMD Ryzen AI 5 PRO 340 at -0.1, the AMD EPYC 9474F at -0.2, and the AMD Ryzen 5 7500F at 0.3.

This CPU's single-thread scores are relevant to Rust's lower-resolution results. At 1080p Low, the system averages 134.1 fps, and at 1080p High it averages 75.2 fps; the 1080p Low value is the highest in the dataset, and the 1080p High value is higher than every 1440p and 4K High figure. As the resolution climbs, the frame rate falls in a way that points to GPU load rather than CPU throughput. The 6-core/12-thread configuration, with a 4.70 GHz boost clock and 3684 Passmark single-thread score, is sufficient for the measured 1080p and 1440p results.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combo rank in Rust is 1306 out of 1717 tested combos. This places the pairing in the lower portion of the field. The CPU's 82nd percentile and the GPU's 68th percentile are both above the overall combo position, which indicates Rust's measured workload is not a best-case scenario for this configuration. The strongest data point is 134.1 fps at 1080p Low, and the weakest is 22.7 fps at 4K Ultra. Because the combo rank uses measured FPS across the resolution/preset grid, the 4K Ultra result pulls the overall position down. The system is still capable of 1080p play, with 75.2 fps at High and 61.4 fps at Ultra, but the high-resolution results are much less competitive. The listed GPU rivals are all within 0.9 percentage points in synthetic score, but those ties do not translate into a higher Rust rank; the in-game measured data is the deciding factor. The dataIsMeasured field is true, so this rank is based on actual FPS runs rather than estimates.
