# Rust with AMD Ryzen 5 7400F + NVIDIA GeForce RTX 3080

This combination of AMD's 6-core Ryzen 5 7400F and NVIDIA's RTX 3080 produces a wide spread of frame rates across resolutions and settings in Rust, ranging from 38 FPS at 4K Ultra to 216 FPS at 1080p Low. The data reveals a system that is heavily influenced by both CPU and GPU workloads depending on the configuration chosen, with the measured results placing this combo at rank 731 out of 2953 tested combinations.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and consistent across all settings, indicating a strong GPU limitation at higher resolutions. At Low settings, the average FPS falls from 216 at 1080p to 148 at 1440p, a reduction of 68 FPS, and then to 88 at 4K—a further drop of 60 FPS. This represents a total decline of approximately 59% from 1080p to 4K at Low settings, showing that the RTX 3080's workload scales dramatically with pixel count.

At High settings, the scaling is similarly pronounced: 122 FPS at 1080p drops to 84 at 1440p and then to 50 at 4K. The 4K result is less than half of the 1080p figure, which strongly suggests the GPU is the primary bottleneck at higher resolutions. The gap between Medium and High settings also widens as resolution increases—at 1080p, Medium runs at 145 FPS versus 122 for High (a 23 FPS gap), while at 4K the difference shrinks to 9 FPS (59 versus 50). This compression of performance differences at 4K indicates that the GPU is saturated regardless of quality preset.

The Ultra preset tells a similar story but with even lower absolute numbers. At 1080p, Ultra achieves 93 FPS, dropping to 64 at 1440p and 38 at 4K. The 4K Ultra result is particularly telling—it is the only configuration that dips below 40 FPS, and the drop from Medium to Ultra at 4K (59 to 38 FPS) is a 21 FPS penalty that highlights how demanding the highest quality settings are at this resolution. The data implies that players targeting 4K will need to make significant compromises in settings to maintain playable frame rates, while 1080p and 1440p offer more headroom.

CPU Role

The Ryzen 5 7400F brings 6 cores and 12 threads, with a base clock of 3.70 GHz and a boost clock of 4.70 GHz. This Zen 4 architecture processor, built on TSMC's 5 nm process, shows strong synthetic performance with a Cinebench R23 multi-core score of 21765 and a single-core score of 3072. The CPU's percentile ranking of 83 versus all CPUs indicates it sits comfortably above the median, though its nearest rivals in aggregate benchmark scores are remarkably close—the Intel Core i5-14600T scores 32707 (0.1% higher), and the AMD Ryzen 7 PRO 6850H scores 32812 (0.2% higher).

In Rust, the CPU's influence is most evident at lower resolutions and settings where the GPU is less burdened. At 1080p Low, the system reaches 216 FPS, which is likely near the CPU's practical limit for this game's simulation and entity processing. The fact that 1080p Medium (145 FPS) and 1080p High (122 FPS) are both well below the Low result suggests that the CPU can push higher frame rates when the GPU is given less work, but the GPU becomes the limiting factor as settings increase.

The 32 MB of shared L3 cache and dual-channel DDR5 memory support with 83.2 GB/s bandwidth provide a solid foundation for Rust's world streaming and player interactions. The CPU's PassMark multithread score of 25645 and single-thread score of 3689 indicate balanced performance that can handle both the game's main thread and background tasks. The data implies that at 1080p, the Ryzen 5 7400F is capable of exceeding 200 FPS in lighter scenarios, but real-world play with populated servers may introduce additional CPU overhead not captured in these measured rows.

GPU Role

The RTX 3080 is built on the Ampere architecture with a GA102 chip containing 8704 shading units, 272 TMUs, and 96 ROPs. Its base clock of 1440 MHz and boost clock of 1710 MHz, combined with 10 GB of GDDR6X memory on a 320-bit bus, deliver 760.3 GB/s of bandwidth. The GPU's percentile ranking of 68 versus all GPUs places it above average, though its nearest rivals in aggregate score are somewhat unexpected—the NVIDIA P106-100 scores 23249 (0.3% higher) and the AMD Radeon RX 6600M scores 23273 (0.4% higher), suggesting these synthetic benchmarks do not fully capture the RTX 3080's gaming strengths.

In Rust, the GPU's role becomes dominant as resolution increases. The measured FPS data shows that at 4K, even the Low preset (88 FPS) struggles to reach the frame rates achieved at 1080p Ultra (93 FPS). The 10 GB VRAM capacity appears sufficient for Rust at these settings, as the game's textures and draw distances do not seem to cause memory-related stuttering in the measured results—the Medium preset at 1440p shows a minimum of 85 FPS and maximum of 115 FPS, indicating consistent frame pacing.

The GPU's 29.77 TFLOPS of FP32 performance and 465.1 GTexel/s texture rate are substantial, yet the 4K Ultra result of 38 FPS demonstrates that Rust's highest settings place extreme demands on even this capable card. The gap between Low and Ultra at 4K (88 versus 38 FPS) is a 50 FPS difference, showing that the GPU's rendering workload for shadows, reflections, and post-processing effects at 4K is the primary constraint. At 1080p, the GPU has more headroom, as evidenced by the 216 FPS Low result, but the CPU may be nearing its limits in this scenario.

How This Combo Ranks

This combination of Ryzen 5 7400F and RTX 3080 ranks 731 out of 2953 tested combos in Rust, placing it in the top 25% of all configurations. This ranking reflects a strong overall pairing that can handle the game well at most settings, though it is not at the very top tier where the most extreme hardware combinations reside. The rank of 731 suggests that while this system delivers excellent performance in absolute terms, there are over 700 combos that achieve higher frame rates, likely featuring more powerful CPUs or GPUs.

The CPU's aggregate benchmark score of 32750 places it in the 83rd percentile, while the GPU's average score of 23172 places it in the 68th percentile. This mismatch—the CPU outperforming the GPU in relative percentile terms—suggests that the RTX 3080 is the more limiting component in this pairing. In Rust, this is confirmed by the resolution scaling data: the frame rate drops significantly at 4K, indicating GPU saturation, while the CPU appears capable of feeding the GPU adequately at lower resolutions.

The combo's rank of 731 out of 2953 means it outperforms approximately 75% of tested systems. This is a respectable position, but the data implies that upgrading the GPU would yield larger gains than upgrading the CPU for this game, especially for players targeting 4K or Ultra settings. At 1080p, the CPU's strength is more relevant, and the system can achieve frame rates well above 100 FPS on most presets, making it well-suited for competitive play or high-refresh-rate monitors.
