Rust

The AMD Ryzen 7 9800X3D paired with the NVIDIA GeForce RTX 4090 delivers a dominant Rust experience, clearing the 60 FPS threshold at every resolution and preset combination tested. At 4K the combo still manages 73 FPS on High settings, while at 1080p it pushes past 250 FPS on Low, making this one of the fastest configurations in the database for this title. The data shows a system that is overkill for 1080p and 1440p gaming, with the bottleneck shifting decisively toward the CPU at lower resolutions and toward the GPU only at 4K Ultra.

Best Settings per Resolution

At 3840x2160, the most demanding preset that maintains at least 60 FPS is High, with an average of 73 FPS. The Ultra preset falls to 56 FPS, which sits below the playable threshold of 60 FPS, while Medium runs at 87 FPS and Low at 129 FPS. For 4K owners, High is the maximum visual quality that keeps the frame rate above the playability line, and the 17 FPS gap between High and Ultra suggests that the latter is only viable if the user accepts sub-60 performance.

At 2560x1440, every setting is playable, and Ultra delivers an average of 94 FPS. The jump from High (124 FPS) to Ultra (94 FPS) costs 30 FPS, but the result remains comfortably above 60. Medium runs at 147 FPS and Low at 219 FPS, so the 1440p Ultra setting is the clear choice for users wanting maximum fidelity without sacrificing smoothness. The 94 FPS average leaves enough headroom for demanding scenes, although the absence of a min FPS value for Ultra means frame drops cannot be assessed from this data.

At 1920x1080, Ultra is the best setting with an average of 137 FPS. High hits 180 FPS, Medium reaches 214 FPS, and Low tops out at 259 FPS. The 1080p Ultra result is 43 FPS higher than the 1440p Ultra result, showing how resolution scaling impacts the RTX 4090. Since all presets exceed 60 FPS by a wide margin, the only reason to drop below Ultra at 1080p is to chase higher refresh rates on a 240Hz or faster monitor.

CPU and GPU Roles

The benchmark data reveals that the CPU plays a dominant role at 1080p, while the GPU becomes increasingly relevant as resolution rises. At 1920x1080, the difference between Low (259 FPS) and Ultra (137 FPS) is 122 FPS, a 47% reduction in performance when moving from the lightest to the heaviest preset. This wide spread indicates that the Ryzen 7 9800X3D is capable of feeding the RTX 4090 at very high frame rates, and the GPU is the limiting factor even at 1080p Ultra. The 8-core, 16-thread CPU with 96 MB of L3 cache provides the single-threaded muscle that Rust demands, as evidenced by the 3DMark single-thread score of 1212 and the PassMark single-thread score of 4430.

At 2560x1440, the scaling from Low (219 FPS) to Ultra (94 FPS) shows a 125 FPS drop, nearly identical to the 1080p spread. This suggests the CPU still has headroom at 1440p, since the frame rate difference between resolutions is moderate for the same preset. For example, High at 1440p (124 FPS) is only 56 FPS lower than High at 1080p (180 FPS), indicating that the GPU is starting to take on more work as pixel count increases.

At 3840x2160, the GPU becomes the clear bottleneck. Low runs at 129 FPS, which is less than half the 1080p Low result of 259 FPS. The gap between Low and Ultra at 4K is 73 FPS (from 129 to 56), a smaller relative drop than at lower resolutions, because the GPU is saturated by the 8.3 million pixel workload. The RTX 4090's 24 GB of GDDR6X memory and 1.01 TB/s bandwidth are sufficient for 4K textures, but the raw compute demand of Rust at 4K Ultra exceeds what the card can deliver at 60 FPS. The data clearly shows a system where the CPU dominates at 1080p and 1440p, while 4K Ultra is the only scenario where the GPU is the sole performance limiter.

Measured FPS Breakdown

At 1920x1080, the full range of settings shows the RTX 4090's headroom. Low averages 259 FPS with no min or max recorded, Medium averages 214 FPS with a min of 182 and max of 246, High averages 180 FPS with no extremes, and Ultra averages 137 FPS with no extremes. The Medium preset provides the only complete frame time data, showing a 64 FPS spread between minimum and maximum, which indicates some scene-dependent variability.

At 2560x1440, Low averages 219 FPS, Medium averages 147 FPS with a min of 125 and max of 169, High averages 124 FPS, and Ultra averages 94 FPS. The Medium spread of 44 FPS is tighter than at 1080p, suggesting that the GPU load is more consistent at higher resolutions. The step from High to Ultra at 1440p costs 30 FPS, which is a significant penalty for the extra visual fidelity.

At 3840x2160, Low averages 129 FPS, Medium averages 87 FPS with a min of 74 and max of 100, High averages 73 FPS, and Ultra averages 56 FPS. The Medium preset at 4K has a 26 FPS spread between min and max, the smallest of any resolution for that setting, confirming that the GPU is the limiting factor and frame times are more stable. The 4K Ultra result of 56 FPS is the only sub-60 number in the entire dataset, and the 17 FPS difference between High and Ultra at this resolution is the largest relative drop among all settings.

Similar Performance Alternatives

For the CPU, the nearest rivals to the Ryzen 7 9800X3D in average benchmark score are the AMD Ryzen 7 PRO 8840HS (0.4% higher score), the AMD Ryzen AI 9 365 (0.7% lower score), the AMD Ryzen AI 7 450 (0.7% higher score), and the AMD Ryzen 7 7700 (0.8% lower score). These four processors all sit within a 1.5% performance band, meaning any of them would deliver nearly identical frame rates in Rust when paired with the RTX 4090. The Ryzen 7 7700, in particular, is a desktop part like the 9800X3D and would likely show the same CPU-bound behavior at 1080p, though the 9800X3D's larger L3 cache gives it an edge in cache-sensitive workloads.

For the GPU, the nearest rivals are the Intel Arc Pro A60 (0% delta), the AMD Radeon Pro Vega 48 (0.3% higher score), the AMD Radeon Pro W6600M (2.5% lower score), and the AMD Radeon PRO V710 (2.9% higher score). The Arc Pro A60 is an exact match in average score, but its professional orientation and likely different driver behavior mean real-world Rust performance could vary. The Radeon Pro W6600M and PRO V710 are workstation cards that would likely struggle with the same game due to driver optimization differences, despite similar synthetic scores. None of these GPU rivals are consumer gaming parts, so the RTX 4090 remains the only sensible choice for Rust among this group.

How This Combo Ranks

The combination of the AMD Ryzen 7 9800X3D and NVIDIA GeForce RTX 4090 ranks 82nd out of 3723 tested combos in Rust, placing it in the top 2.2% of all configurations. This ranking reflects the CPU's 87th percentile among all CPUs and the GPU's 88th percentile among all GPUs, both of which are near the top of their respective charts. The 82nd rank means there are 81 other combinations that perform better in Rust, but given that this hardware represents the current flagship consumer CPU and the previous-generation flagship GPU, the only faster systems would likely feature the RTX 4090's successor or an even more extreme CPU configuration. The rank of 82 out of 3723 is consistent with a setup that delivers playable frame rates at every resolution, with only the 4K Ultra preset falling below 60 FPS.
