Rust

The AMD Ryzen 7 9700F paired with the NVIDIA GeForce RTX 4090 delivers exceptional performance in Rust, clearing the 60 FPS playable threshold across nearly every resolution and preset combination tested. The only exception is 4K Ultra, where the average frame rate drops to 56 FPS, just below the 60 FPS target. This combination ranks 66th out of 3723 tested CPU/GPU combos for this game, placing it in the top 2% of all configurations. The data confirms a system that is massively overqualified for 1080p and 1440p gaming, with the RTX 4090's raw power only beginning to be challenged at 4K with maximum settings.

Measured FPS Breakdown

The measured frame rates show a clear pattern of diminishing returns as resolution increases, but the RTX 4090 maintains high performance throughout. At 1920x1080, the system is heavily CPU-bound, with the GPU barely breaking a sweat. Low settings produce an average of 276 FPS, which is the highest frame rate recorded in the entire test suite. Medium settings still deliver 214 FPS average, with a minimum of 182 FPS and maximum of 246 FPS, indicating excellent frame pacing. High settings yield 180 FPS average, while Ultra settings drop to 137 FPS average. Even at 1080p Ultra, the frame rate remains nearly 2.3 times above the 60 FPS playable threshold, making this resolution entirely trivial for the hardware.

Stepping up to 2560x1440, performance remains remarkably strong. Low settings produce 219 FPS average, Medium settings deliver 147 FPS average with a minimum of 125 FPS and maximum of 169 FPS. High settings maintain 124 FPS average, and Ultra settings stay at 94 FPS average. The scaling from 1080p to 1440p shows roughly a 20-25% performance drop at each preset, which is consistent with the increased pixel count. The 1440p Ultra result of 94 FPS is particularly notable because it shows the system can handle maximum settings at this resolution with substantial headroom above the 60 FPS threshold.

At 3840x2160, the RTX 4090 finally starts to feel some pressure. Low settings deliver 129 FPS average, which is still extremely high for 4K. Medium settings produce 87 FPS average with a minimum of 74 FPS and maximum of 100 FPS. High settings achieve 73 FPS average, maintaining playability with some margin. The Ultra preset drops to 56 FPS average, which is the only setting across all tests that fails to reach the 60 FPS playable threshold. The gap between High and Ultra at 4K is significant, representing a 17 FPS drop. This suggests that the Ultra preset at 4K introduces effects that heavily tax even the most powerful consumer GPU available.

The minimum frame rate data available shows consistent behavior. At 1080p Medium, the 182 FPS minimum indicates no problematic stutters or drops. At 1440p Medium, the 125 FPS minimum maintains a comfortable buffer above 60 FPS. At 4K Medium, the 74 FPS minimum still clears the playable threshold, though with less margin. These minimums suggest that the system maintains stable frame delivery without sudden dips, which is critical for a survival game where sudden frame drops can affect combat responsiveness.

CPU and GPU Roles

The relative importance of the CPU versus GPU shifts dramatically across resolutions. At 1920x1080, the system produces frame rates between 137 FPS (Ultra) and 276 FPS (Low), indicating the GPU is not the limiting factor. The Ryzen 7 9700F, with its 8 cores and 16 threads based on Zen 5 architecture, provides enough single-thread performance (4691 PassMark single-thread score) to feed the RTX 4090 at this resolution. The fact that 1080p Low produces 276 FPS while 1080p Ultra produces 137 FPS suggests that even at 1080p, the GPU is doing meaningful work at higher presets, but the CPU is capable of supporting extreme frame rates when the GPU load is light.

Moving to 2560x1440, the balance shifts toward the GPU. The frame rates range from 219 FPS at Low to 94 FPS at Ultra, showing that the increased pixel count begins to engage the RTX 4090 more fully. The 1440p Ultra result of 94 FPS is 43 FPS lower than 1080p Ultra, indicating the GPU is now the primary performance driver. The CPU still has headroom, as evidenced by the 219 FPS Low result, but the GPU's workload at higher presets is becoming significant.

At 3840x2160, the RTX 4090 is clearly the dominant factor. The frame rates range from 129 FPS at Low to 56 FPS at Ultra, and the scaling between presets becomes more pronounced. The difference between 1080p Low (276 FPS) and 4K Low (129 FPS) is 147 FPS, a 53% reduction that is entirely attributable to the GPU's pixel throughput. The 4K Ultra result of 56 FPS shows the RTX 4090 reaching its limits with Rust's most demanding settings. The CPU's role at 4K is minimal, as the GPU is fully saturated.

The scaling between resolutions provides clear evidence of the GPU's importance. At Medium settings, the frame rates are 214 FPS at 1080p, 147 FPS at 1440p, and 87 FPS at 4K. This represents a 59% reduction from 1080p to 4K, which aligns with the 4x increase in pixel count. The RTX 4090's 24 GB of GDDR6X memory and 1.01 TB/s bandwidth are sufficient to handle Rust's textures at all resolutions, but the raw compute power (82.58 TFLOPS FP32) is what drives the frame rate differences.

Similar Performance Alternatives

The Ryzen 7 9700F has nearest rivals that would produce nearly identical CPU performance in Rust. The AMD Ryzen 9 7940HX has an average benchmark score of 69875, which is 0.2% higher than the 9700F's 69996 average. This mobile flagship CPU would deliver essentially the same frame rates in CPU-bound scenarios, such as 1080p Low where the system reaches 276 FPS. The Intel Core i7-14700KF scores 70163 on average, 0.2% higher, making it statistically indistinguishable in gaming workloads. The AMD Ryzen 9 7950X scores 69515, 0.7% lower, while the Intel Core i7-14700K scores 69355, 0.9% lower. All four alternatives fall within a 1.6% performance band, meaning any of them paired with an RTX 4090 would produce nearly identical Rust performance.

For the GPU side, the nearest rivals to the RTX 4090 are less conventional. The Intel Arc Pro A60 has an average score of 60326, essentially matching the RTX 4090's 60347 average (0% delta). However, the Arc Pro A60 is a workstation card, and its gaming performance in Rust would not match the RTX 4090 despite the similar benchmark average. The AMD Radeon Pro Vega 48 scores 60140, 0.3% lower, and the AMD Radeon Pro W6600M scores 61896, 2.5% higher. The AMD Radeon PRO V710 scores 58657, 2.9% lower. These workstation and mobile GPUs share similar synthetic benchmark scores but would behave differently in actual Rust gameplay. The RTX 4090's 16384 shading units, 128 RT cores, and 512 tensor cores give it a level of gaming performance that these rivals cannot replicate, despite the benchmark averages suggesting otherwise.

The practical takeaway is that for CPU selection, any of the four nearest rivals would deliver identical Rust performance when paired with an RTX 4090. For GPU selection, the benchmark comparisons are misleading; the RTX 4090 is in a different class for gaming despite the similar average scores. The 88th percentile ranking among all GPUs and the measured frame rates in Rust confirm its dominance.

Best Settings per Resolution

At 3840x2160, the most demanding preset that maintains at least 60 FPS average is High, which produces 73 FPS. Medium settings deliver 87 FPS and Low delivers 129 FPS, but High offers the best visual quality while staying above the threshold. The Ultra preset at 56 FPS is not playable by the 60 FPS standard. Players wanting maximum quality at 4K should select High and accept the 73 FPS average.

At 2560x1440, Ultra settings are fully playable with an average of 94 FPS. This is the highest preset and the best visual experience at this resolution. All four presets exceed 60 FPS, with Low at 219 FPS, Medium at 147 FPS, and High at 124 FPS. The Ultra preset's 94 FPS average provides a comfortable margin above the playable threshold, making it the clear recommendation for 1440p.

At 1920x1080, Ultra settings average 137 FPS, which is more than double the playable threshold. Every preset is playable, with Low at 276 FPS, Medium at 214 FPS, and High at 180 FPS. The Ultra preset is the obvious choice for 1080p, as the system has enormous headroom even with maximum settings. There is no scenario at 1080p where frame rate becomes a concern.

The Verdict

This PC can run Rust exceptionally well across all tested resolutions, with one notable exception. At 1920x1080, all four presets clear 60 FPS, with Ultra delivering 137 FPS average and Low reaching 276 FPS. This resolution is entirely playable with maximum settings. At 2560x1440, all four presets also clear 60 FPS, with Ultra at 94 FPS average providing a smooth experience with full visual fidelity. This is the sweet spot for this hardware combination.

At 3840x2160, three of the four presets are playable. High settings average 73 FPS, Medium averages 87 FPS, and Low averages 129 FPS. The Ultra preset fails to reach 60 FPS, averaging only 56 FPS. The verdict for 4K is that the system is playable at High settings, which still delivers a strong 73 FPS average. Players who insist on 4K Ultra would need to accept the sub-60 FPS performance or lower to High. Overall, this combination of AMD Ryzen 7 9700F and NVIDIA GeForce RTX 4090 is one of the strongest configurations for Rust, ranking 66th out of 3723 tested combos. The only compromise required is at 4K Ultra, where the game's most demanding settings exceed what even the flagship RTX 4090 can deliver at playable frame rates.
