# Rust with AMD Ryzen 5 7400F + NVIDIA GeForce RTX 5090

This combination ranks 112th out of 2,953 tested combos in Rust, placing it in the top 4% of all systems evaluated. The pairing of AMD's 6-core Zen 4 processor with NVIDIA's flagship Blackwell GPU produces a system that handles Rust exceptionally well across all resolutions, though the data reveals a clear pattern: the RTX 5090 is the dominant force at 4K, while the Ryzen 5 7400F becomes increasingly relevant as resolution drops. At 1080p, the CPU constrains performance; at 4K, the GPU workload dominates. The measured frame rates show this system delivers playable performance even at the most demanding settings, with the gap between Low and Ultra presets widening dramatically as resolution increases.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial and reveals where the bottleneck lies. At Low settings, the system produces 216 FPS at 1080p, 190 FPS at 1440p, and 132 FPS at 4K — a drop of 84 FPS (39%) from 1080p to 4K. This scaling pattern suggests that even at Low settings, the GPU is doing significant work, but the CPU still has headroom. The 1080p Low result of 216 FPS is the highest measured in the entire dataset, indicating that the Ryzen 5 7400F can feed the RTX 5090 enough frames to reach very high refresh rates at the lowest preset.

At Medium settings, the scaling is more gradual. The system produces 185 FPS at 1080p, 150 FPS at 1440p, and 89 FPS at 4K. The drop from 1080p to 1440p is 35 FPS (19%), while the drop from 1440p to 4K is 61 FPS (41%). This indicates that the GPU becomes the limiting factor at 4K Medium, while the CPU still has capacity at 1080p and 1440p Medium. The 4K Medium result of 89 FPS with a minimum of 76 FPS shows the system maintains playable frame rates even in demanding scenes.

High settings show a similar pattern. The system achieves 175 FPS at 1080p, 127 FPS at 1440p, and 75 FPS at 4K. The 1080p to 1440p drop is 48 FPS (27%), while the 1440p to 4K drop is 52 FPS (41%). The 4K High result of 75 FPS suggests that this is the boundary where the GPU's raw compute power begins to be the primary constraint. The RTX 5090's 32 GB of GDDR7 memory and 1.79 TB/s bandwidth are sufficient for 4K High textures, but the sheer pixel count at 3840x2160 reduces performance dramatically compared to 1440p.

Ultra settings produce the most dramatic scaling. The system delivers 140 FPS at 1080p, 97 FPS at 1440p, and 57 FPS at 4K. The drop from 1080p to 4K is 83 FPS (59%), the largest percentage decline across all settings. This indicates that Ultra settings at 4K are pushing the RTX 5090 to its limits, with the GPU fully saturated. The 57 FPS result at 4K Ultra is the lowest measured in the dataset, but it remains above the threshold for smooth gameplay in most scenarios.

The scaling data points to the GPU as the primary limiting factor at 4K. The RTX 5090's 104.8 TFLOPS of FP32 performance and 423.6 GPixel/s pixel rate are impressive, but Rust's open-world survival mechanics with complex lighting and shadow calculations at 4K Ultra demand more than even this flagship can deliver at 60+ FPS. At 1080p, however, the CPU becomes more relevant — the 216 FPS Low result and 185 FPS Medium result suggest the Ryzen 5 7400F's 6 cores and 12 threads are sufficient to keep up with the GPU's output at lower resolutions.

Settings Recommendations

The measured data strongly favors Medium settings as the optimal balance between visual quality and performance. At 1080p, Medium delivers 185 FPS average with a minimum of 157 FPS and maximum of 213 FPS. This represents a 69 FPS improvement over Ultra (140 FPS) while maintaining smooth frame delivery. The minimum frame rate of 157 FPS at 1080p Medium is particularly notable — it ensures that even during intense gameplay moments, the system stays well above the 144 Hz refresh rate threshold.

At 1440p, Medium produces 150 FPS average with a minimum of 128 FPS and maximum of 173 FPS. This is 53 FPS higher than Ultra (97 FPS) and only 40 FPS lower than Low (190 FPS). The 128 FPS minimum at 1440p Medium means the system rarely dips below 120 FPS, providing a consistently smooth experience. For gamers with 1440p 144 Hz monitors, Medium settings deliver the best experience — Ultra would require dropping below 100 FPS, while Low sacrifices too much visual quality for a marginal 40 FPS gain.

At 4K, Medium is the only settings tier that provides both playable frame rates and reasonable visual fidelity. The 89 FPS average with 76 FPS minimum and 102 FPS maximum is respectable for 4K gaming, especially considering Rust's demanding open-world rendering. High settings at 4K drop to 75 FPS average, which is still playable but leaves less headroom for demanding scenes. Ultra at 4K produces 57 FPS, which may be acceptable for slower-paced gameplay but is not ideal for competitive scenarios.

The data suggests that Low settings are unnecessary for this combination. Even at 4K, Low produces 132 FPS — 43 FPS higher than Medium — but the visual quality trade-off is substantial. The RTX 5090's 32 GB of VRAM and 21760 shading units can handle Rust's textures and effects at Medium and High settings without issue. The sweet spot is Medium at all resolutions, with High being a viable alternative for users who prioritize visual fidelity over maximum frame rates.

How This Combo Ranks

The combo rank of 112 out of 2,953 tested combos places this system in the 96th percentile of all tested configurations. This is an exceptional ranking, though not surprising given the RTX 5090's position as the flagship GPU in NVIDIA's 50-series lineup. The GPU's percentile rank of 92 among all GPUs and the CPU's percentile rank of 83 among all CPUs indicate that both components are near the top of their respective performance hierarchies.

The Ryzen 5 7400F's nearest rivals in the CPU benchmark database include the Intel Core i5-14600T (0.1% higher average score), Intel Core Ultra 7 155H (0.2% higher), AMD Ryzen 7 PRO 6850H (0.2% lower), and AMD Ryzen AI 7 PRO 360 (0.3% higher). These deltas are all within a fraction of a percent, meaning the 7400F's average benchmark score of 32,750 is statistically indistinguishable from its closest competitors. This suggests that the CPU is not the differentiator in this combo's ranking — it is the GPU that drives the high rank.

The RTX 5090's nearest rivals include the NVIDIA Tesla P100 PCIe 16 GB (0.3% higher average score), Tesla P100 PCIe 12 GB (0.6% higher), AMD Radeon RX 6850M XT (1.1% higher), and AMD Radeon Pro Vega 64X (1.4% lower). These deltas are slightly larger than the CPU's rival deltas, but still relatively small. The GPU's average benchmark score of 79,842 places it just below some workstation-oriented cards, but in gaming workloads like Rust, the RTX 5090's gaming-specific features and driver optimizations likely give it an advantage that synthetic benchmarks do not fully capture.

The combination of a top-4% GPU with a mid-to-high-range CPU results in a rank that is higher than either component's individual percentile would suggest. This indicates that Rust's performance profile benefits from the GPU being the dominant component, with the CPU providing sufficient support without becoming a significant bottleneck. The 112th rank out of 2,953 combos means there are only 111 configurations that perform better in Rust — likely those pairing the RTX 5090 with higher-end CPUs or possibly SLI/CrossFire configurations.

Measured FPS Breakdown

At 1920x1080, the system delivers its strongest performance. Low settings produce 216 FPS average, the highest result in the entire dataset. Medium settings yield 185 FPS with a minimum of 157 FPS and maximum of 213 FPS. High settings achieve 175 FPS average, while Ultra settings produce 140 FPS. The spread from Low to Ultra at 1080p is 76 FPS, indicating that the GPU has significant headroom at this resolution, and the CPU is likely the limiting factor at Low and Medium settings.

At 2560x1440, performance remains strong but shows the expected decline. Low settings deliver 190 FPS average, which is 26 FPS lower than 1080p Low. Medium settings produce 150 FPS with a minimum of 128 FPS and maximum of 173 FPS. High settings achieve 127 FPS average, while Ultra settings drop to 97 FPS. The spread from Low to Ultra at 1440p is 93 FPS, wider than at 1080p, indicating that the GPU is becoming more of a factor as pixel count increases.

At 3840x2160, the GPU workload dominates. Low settings produce 132 FPS average, which is still highly playable. Medium settings deliver 89 FPS with a minimum of 76 FPS and maximum of 102 FPS. High settings achieve 75 FPS average, while Ultra settings drop to 57 FPS. The spread from Low to Ultra at 4K is 75 FPS, similar to 1080p's spread, but the absolute values are much lower. The 4K Medium result of 89 FPS is the most balanced — it maintains 76 FPS minimums while providing better visuals than Low.

The minimum frame rate data is only available for Medium settings, but it provides valuable insight. At 1080p Medium, the minimum of 157 FPS is 85% of the average, indicating consistent frame delivery. At 1440p Medium, the minimum of 128 FPS is 85% of the average, showing similar consistency. At 4K Medium, the minimum of 76 FPS is 85% of the average, meaning the system maintains a tight frame pacing even under load. The maximum frame rates at Medium settings — 213 FPS at 1080p, 173 FPS at 1440p, and 102 FPS at 4K — show that the system can burst well above its averages in less demanding scenes.

GPU Role

The NVIDIA GeForce RTX 5090 is the primary driver of this system's Rust performance. With 32 GB of GDDR7 memory on a 512-bit bus, the GPU has more than enough VRAM for Rust's largest texture sets at any resolution. The 1.79 TB/s memory bandwidth ensures that texture streaming and asset loading never become a bottleneck, even during rapid movement through Rust's open world. The GPU's base clock of 2017 MHz and boost clock of 2407 MHz provide substantial compute throughput, with 21,760 shading units capable of processing 104.8 TFLOPS of FP32 work.

The 4K results demonstrate the GPU's capabilities clearly. At 4K Medium, the system produces 89 FPS average — a solid result for a demanding survival game at 4K resolution. The jump from Medium to High at 4K costs 14 FPS (75 FPS vs 89 FPS), while the jump from High to Ultra costs 18 FPS (57 FPS vs 75 FPS). This suggests that the RTX 5090's performance scales predictably with settings, with each tier of visual quality requiring progressively more GPU compute. The 4K Ultra result of 57 FPS indicates that even this flagship GPU cannot maintain 60+ FPS at maximum settings in Rust at 4K.

The GPU's 170 ray tracing cores and 680 tensor cores are not directly measured in the Rust FPS data, but they contribute to the overall compute capability. Rust does not heavily utilize ray tracing, so the RTX 5090's ray tracing performance is not a significant factor in these results. The GPU's pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s are more relevant — these determine how quickly the GPU can fill pixels and apply textures, directly impacting frame rates in a visually dense game like Rust.

The GPU's 92nd percentile rank among all GPUs and its average benchmark score of 79,842 place it near the top of the performance hierarchy. Its nearest rivals — the Tesla P100 PCIe 16 GB and 12 GB — are workstation cards not designed for gaming, so the RTX 5090's gaming performance in Rust is likely better than the synthetic benchmark deltas suggest. The 1.1% delta to the AMD Radeon RX 6850M XT is notable, but that mobile GPU cannot match the RTX 5090's 32 GB VRAM or 512-bit memory bus.

CPU Role

The AMD Ryzen 5 7400F plays a supporting role in this combination, and the data shows its influence is most pronounced at lower resolutions. With 6 cores and 12 threads based on the Zen 4 architecture, the CPU provides solid single-threaded performance that Rust requires for its game logic and physics calculations. The base clock of 3.70 GHz and boost clock of 4.70 GHz are competitive, and the 32 MB of shared L3 cache helps reduce memory latency in cache-sensitive workloads.

The 1080p results reveal the CPU's impact. At 1080p Low, the system produces 216 FPS, which is likely near the CPU's maximum frame output capability. The fact that 1080p Low (216 FPS) is only 26 FPS higher than 1440p Low (190 FPS) — despite the 1440p having 78% more pixels — suggests that the CPU is becoming the limiting factor at 1080p. At 1080p Medium, the system produces 185 FPS, and at 1080p High, 175 FPS — these results are closer to the 1440p equivalents (150 FPS and 127 FPS) than the resolution difference would suggest, further indicating CPU limitation.

The CPU's benchmark scores support this interpretation. The Cinebench R23 multicore score of 21,765 and single-core score of 3,072 are solid mid-range results. The PassMark single-thread score of 3,689 and multithread score of 25,645 show balanced performance. The CPU's 83rd percentile rank among all CPUs indicates it is a capable processor, but not a top-tier one — there are many CPUs with higher single-threaded performance that could push 1080p frame rates higher.

At 4K, the CPU's role diminishes significantly. The 4K results show a clear GPU bottleneck — the frame rate differences between settings tiers (132 FPS Low, 89 FPS Medium, 75 FPS High, 57 FPS Ultra) are consistent with GPU workload scaling. The CPU's 6 cores and 12 threads are sufficient to feed the RTX 5090 at 4K, as the GPU's pixel processing becomes the dominant cost. The CPU's DDR5 memory support with 83.2 GB/s bandwidth ensures that system memory is not a bottleneck, though the GPU's 1.79 TB/s bandwidth is far higher.

The CPU's nearest rivals — the Intel Core i5-14600T, Intel Core Ultra 7 155H, AMD Ryzen 7 PRO 6850H, and AMD Ryzen AI 7 PRO 360 — all have average scores within 0.3% of the 7400F. This indicates that the CPU is well-matched with its peers, and no single rival offers a significant performance advantage in Rust. The CPU's TDP of 65 watts and 5 nm process node from TSMC mean it runs efficiently, allowing the RTX 5090's 575-watt TDP to be the primary power consideration in this system.
