Rust

The AMD Ryzen 9 5900X paired with the NVIDIA GeForce RTX 4090 is an exceptionally high-end combination for running Rust, delivering playable frame rates at every resolution tested, including 4K Ultra. The data shows a system that is heavily GPU-bound at higher resolutions but still provides a massive performance headroom at 1080p, where even the most demanding preset remains far above the 60 FPS playable threshold.

Measured FPS Breakdown

The measured FPS data for this combo covers three resolutions and four quality presets, providing a clear picture of scaling. All scores are average FPS, as minimum and maximum values were not recorded in the dataset.

1920x1080 (1080p):

• Low: 202.0 FPS average
• Medium: 174.9 FPS average
• High: 163.9 FPS average
• Ultra: 136.6 FPS average

At 1080p, the combo is clearly capable of pushing frame rates well beyond what most high-refresh monitors can display. The jump from Low to Ultra costs roughly 65 FPS, which is a significant drop but still leaves the Ultra preset comfortably above the playable threshold. The scaling between presets is not linear; the gap between Medium and High (11.0 FPS) is smaller than the gap between High and Ultra (27.3 FPS), indicating that the Ultra preset introduces a substantial load increase.

2560x1440 (1440p):

• Low: 178.9 FPS average
• Medium: 146.3 FPS average
• High: 122.6 FPS average
• Ultra: 95.2 FPS average

Moving to 1440p, the frame rates remain impressive. The Ultra preset still holds onto 95.2 FPS, which is well above the 60 FPS threshold. The relative performance drop from Low to Ultra is larger here than at 1080p, with a reduction of 83.7 FPS, suggesting the GPU is starting to become a more limiting factor. The High preset at 122.6 FPS offers a strong balance for users seeking high refresh rates at this resolution.

3840x2160 (4K):

• Low: 132.7 FPS average
• Medium: 87.1 FPS average
• High: 75.4 FPS average
• Ultra: 54.6 FPS average

At 4K, the Ultra preset drops below the playable threshold of 60 FPS, landing at 54.6 FPS. This is the only setting in the entire dataset that fails to maintain smooth gameplay. The High preset is the most demanding playable option at 75.4 FPS, which is a strong result for 4K. The gap between Low and Medium is particularly stark, a 45.6 FPS difference, which highlights how much the medium settings increase the GPU workload at this resolution.

CPU and GPU Roles

The data clearly shows that the GPU becomes progressively more important as resolution increases, while the CPU's role is more prominent at lower resolutions. This is a standard scaling pattern, but the magnitude of the changes here is worth examining.

At 1080p, the CPU has a significant influence on performance. The 202.0 FPS on Low settings suggests that the Ryzen 9 5900X is feeding the RTX 4090 effectively, but the large frame rate drop when moving to Ultra (136.6 FPS) indicates that the GPU is still doing most of the work. The fact that the gap between Low and Ultra at 1080p (65.4 FPS) is smaller than at 1440p (83.7 FPS) confirms that the CPU is holding the system back from reaching even higher frame rates on lower settings. The Ryzen 9 5900X, with its 12 cores and 24 threads, is powerful, but Rust's engine typically doesn't scale perfectly with all cores.

At 1440p, the balance shifts. The Ultra preset at 95.2 FPS shows that the GPU is now the primary bottleneck, as the frame rate is much closer to the 4K results than to the 1080p results. The scaling from Low (178.9) to Ultra (95.2) is roughly a 47% reduction in performance, which is a typical sign of GPU-bound behavior. The CPU is still capable, but it is no longer the limiting factor at this resolution.

At 4K, the RTX 4090 is clearly the dominant component. The difference between Low (132.7) and High (75.4) is a 57.3 FPS gap, while the drop from High to Ultra (20.8 FPS) is smaller. This indicates that the GPU is saturated, and the CPU's role is diminished. The 4K Low result of 132.7 FPS is still higher than the 1440p Ultra result, which is a strong indicator that the GPU's raw throughput is the key driver here. The Ryzen 9 5900X provides adequate support, but the data suggests that even a slower CPU would yield similar 4K results with this GPU.

How This Combo Ranks

The combo ranks 217th out of 3723 tested combinations, placing it in the top percentile of all systems tested for Rust. This is a percentile rank of approximately 94.2% (calculated as 1 - 217/3723), meaning it outperforms the vast majority of other hardware pairings in this game.

The CPU's individual performance metrics support this ranking. The Ryzen 9 5900X has an average benchmark score of 41376 and sits in the 87th percentile of all CPUs. Its nearest rivals include the Intel Core Ultra 7 366H (scoring 41263, a 0.3% difference) and the Intel Core i7-14650HX (scoring 41576, a -0.5% difference). These are extremely close scores, suggesting that the 5900X's performance is tightly clustered with other high-end processors.

The RTX 4090's individual performance is similarly impressive. With an average benchmark score of 60347 and an 88th percentile rank, it is one of the most powerful GPUs available. Its nearest rivals are the Intel Arc Pro A60 (scoring 60326, a 0% difference) and the AMD Radeon Pro W6600M (scoring 61896, a -2.5% difference). The fact that a professional-grade GPU like the Radeon Pro W6600M scores higher in synthetic benchmarks but the RTX 4090 ranks higher in this specific game test highlights the importance of game-specific optimization.

The high combo rank is a direct result of the synergy between these two components. The CPU is strong enough to avoid bottlenecking the GPU at lower resolutions, and the GPU is powerful enough to handle the heavy load at 4K, even if the Ultra preset is not playable.

Similar Performance Alternatives

Based on the nearestRivals data for both the CPU and GPU, there are several alternative components that would likely produce very similar performance in Rust.

For the CPU, the Intel Core Ultra 7 366H (avg score 41263, 0.3% slower) and the Intel Core Ultra 7 356H (avg score 41215, 0.4% slower) are the closest matches. The AMD Ryzen AI 5 PRO 440 (avg score 41208, 0.4% slower) is also nearly identical. The Intel Core i7-14650HX (avg score 41576, 0.5% faster) is the only rival that edges out the 5900X. All of these CPUs would deliver a nearly indistinguishable experience in Rust, as the differences are within the margin of error for synthetic benchmarks.

For the GPU, the Intel Arc Pro A60 (avg score 60326, 0% difference) is the most direct equivalent. The AMD Radeon Pro Vega 48 (avg score 60140, 0.3% slower) and the AMD Radeon PRO V710 (avg score 58657, 2.9% slower) are also close, though the V710 shows a more noticeable performance deficit. The AMD Radeon Pro W6600M (avg score 61896, 2.5% faster) would be a slightly stronger option in raw compute, but its game-specific performance in Rust could differ.

When combining these, a system with an Intel Core i7-14650HX and an AMD Radeon Pro W6600M would likely have a higher synthetic benchmark score than the 5900X + RTX 4090 combo. However, the actual in-game performance would depend on driver optimization and Rust's engine quirks. The data shows that the RTX 4090's nearest rivals are all professional-grade GPUs, not gaming-focused ones, which means the RTX 4090's gaming-specific optimizations likely give it an edge in Rust that synthetic benchmarks do not fully capture.

Best Settings per Resolution

The following settings represent the most demanding preset that stays at or above 60 FPS average for each resolution:

1920x1080: Ultra settings are fully playable with an average of 136.6 FPS. This is the highest quality option and leaves substantial headroom above the 60 FPS threshold. Users can enjoy maximum visual fidelity without any performance concerns.

2560x1440: Ultra settings also work here, achieving 95.2 FPS average. While this is lower than the 1080p result, it remains well above the playable threshold. This is the recommended choice for 1440p displays.

3840x2160: High settings are the best option, delivering 75.4 FPS average. The Ultra preset falls to 54.6 FPS and is not playable. Users at 4K must sacrifice the highest quality settings to maintain smooth gameplay. The Medium preset at 87.1 FPS is also viable, but High offers a better visual experience while still staying above the threshold.
