Rust

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 4060 delivers a playable yet heavily resolution-dependent experience in Rust, with the data revealing a clear bottleneck shift as pixel count rises. At 1080p, the combination achieves a strong 164.8 FPS on Low settings, indicating the CPU is feeding the GPU efficiently. However, cranking the resolution to 4K on Ultra drops performance to a stutter-prone 28.3 FPS, a massive 83% reduction from the 1080p Low figure. This pattern suggests that while the 12-core CPU provides ample headroom for high frame rates at lower resolutions, the RTX 4060’s 8 GB VRAM and 128-bit memory interface become the limiting factor at higher graphical loads. The measured data shows a progressive decline across all settings as resolution increases, with the gap between Low and Ultra widening from 96.8 FPS at 1080p to 37.9 FPS at 4K, underscoring how the GPU struggles to maintain consistent throughput when pixel shading demands escalate.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all four settings presets, pointing directly to the GPU as the primary constraint at higher resolutions. At 1080p, the Low preset hits 164.8 FPS, which is 97% higher than the 4K Low result of 66.2 FPS. Moving to Medium, the 1080p score of 108.5 FPS falls to 46.4 FPS at 4K, a 57% reduction. The High preset follows a similar trajectory, dropping from 91.8 FPS at 1080p to 37.8 FPS at 4K, a 59% loss. The Ultra preset is the most punishing, with 68 FPS at 1080p collapsing to 28.3 FPS at 4K, a 58% decline.

These numbers indicate that the RTX 4060’s rendering throughput is the dominant factor in determining frame rates at 1440p and above. The CPU’s 12 cores and 24 threads, with a boost clock of 5.60 GHz, are more than capable of feeding the GPU at 1080p, as evidenced by the 164.8 FPS Low result. However, the GPU’s 272.0 GB/s memory bandwidth and 15.11 TFLOPS FP32 performance are insufficient to maintain high frame rates when the pixel count quadruples from 1080p to 4K. The data shows that the scaling penalty from 1440p to 4K is proportionally larger than from 1080p to 1440p, suggesting the GPU hits a hard ceiling around the 4K mark. For instance, at High settings, 1440p yields 65 FPS, but 4K only manages 37.8 FPS, a 42% drop, whereas the 1080p to 1440p transition only loses 29% of performance. This non-linear degradation is a classic sign of VRAM capacity or memory bandwidth saturation.

Q: What is the combo’s rank among all tested configurations for Rust?

A: The combo ranks 957th out of 1717 tested combinations, placing it in the lower-middle tier of all systems tested for this game.

Q: How does the RTX 4060 compare to its closest rival in synthetic benchmarks?

A: The RTX 4060’s average benchmark score is 23181, which is 0.6% lower than the AMD Radeon RX 6600M and 0.7% lower than the NVIDIA GeForce GTX 780 Ti, but 0.7% higher than the Intel Arc B580.

How This Combo Ranks

The combo’s rank of 957 out of 1717 tested configurations places it in the 56th percentile of all systems benchmarked for Rust. This positioning is modest, reflecting the GPU’s mid-range standing in the overall hierarchy. The CPU, however, is a high performer, ranking in the 93rd percentile against all CPUs with an average benchmark score of 50556. The disparity between the CPU’s strong standing and the combo’s middling rank highlights the GPU’s role as the performance limiter in this pairing.

Comparing the CPU to its nearest rivals, the Ryzen 9 7900X scores 50556, which is 0.1% lower than the Intel Core Ultra 5 235 (50598) and 0.4% lower than the AMD Ryzen 9 5900XT (50738). It also trails the Intel Core i7-13850HX by 0.5% and the Intel Core i9-13980HX by 0.8%. These small deltas indicate that the CPU is competitive with top-tier alternatives, yet the GPU’s performance relative to its peers is less favorable. The RTX 4060’s average score of 23181 is 0.6% below the AMD Radeon RX 6600M and 0.7% below the NVIDIA GeForce GTX 780 Ti, though it edges out the Intel Arc B580 by 0.7%. Given that the GPU ranks in the 66th percentile against all GPUs, the combo’s overall rank is dragged down by the graphics card’s mid-tier positioning.

Measured FPS Breakdown

The measured data provides a granular view of performance across three resolutions and four settings presets. At 1920x1080, the Low preset delivers 164.8 FPS, which is the highest recorded figure in the entire dataset. Medium settings at this resolution produce 108.5 FPS, High yields 91.8 FPS, and Ultra drops to 68 FPS. The scaling from Low to Ultra at 1080p shows a 59% performance penalty, indicating that the GPU’s fill rate and shader throughput are heavily taxed by the Ultra preset’s additional effects.

Moving to 2560x1440, the Low preset still manages a smooth 112 FPS, but the drop-off becomes more pronounced. Medium hits 74.6 FPS, High falls to 65 FPS, and Ultra bottoms out at 50.4 FPS. The transition from 1080p to 1440p at Low settings results in a 32% loss, while at Ultra, the loss is 26%. This suggests that the GPU’s memory bandwidth starts to become a bottleneck as the resolution increases, though the CPU’s 64 MB L3 cache and 83.2 GB/s memory bandwidth help mitigate some of the strain.

At 3840x2160, the performance falls below playable thresholds for most presets. Low settings yield 66.2 FPS, Medium drops to 46.4 FPS, High reaches 37.8 FPS, and Ultra plummets to 28.3 FPS. The 4K results highlight the RTX 4060’s limitations, as even the Low preset struggles to maintain a smooth 60 FPS target. The data shows that the GPU’s 8 GB GDDR6 memory on a 128-bit bus is insufficient for Rust’s texture-heavy environments at 4K, leading to significant frame rate drops.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor based on the Zen 4 architecture, with a base clock of 4.70 GHz and a boost clock of 5.60 GHz. Its 64 MB of shared L3 cache and 13,140 million transistors on a 5 nm TSMC process provide substantial computational headroom for Rust’s simulation-heavy gameplay. In synthetic benchmarks, the CPU achieves a score of 43695 in Cinebench R23 multicore and 6168 in single-core, demonstrating strong multi-threaded and single-threaded performance.

The CPU’s role in Rust is evident from the 1080p Low result of 164.8 FPS, which indicates that the processor can drive frame rates well above 150 FPS when the GPU is not stressed. The 24 threads allow for efficient handling of Rust’s world simulation, physics, and entity updates, which are typically CPU-bound. However, the data also shows that the CPU is not the limiting factor at higher resolutions. At 4K Ultra, the FPS drops to 28.3, which is far below what the CPU could theoretically support. This confirms that the GPU’s 15.11 TFLOPS FP32 performance and 272.0 GB/s memory bandwidth are the primary bottlenecks. The CPU’s 83.2 GB/s memory bandwidth, while lower than the GPU’s, is sufficient for feeding the processor’s cores, as evidenced by the high frame rates at 1080p.

Settings Recommendations

Based on the measured FPS data, the optimal settings preset depends heavily on the target resolution. At 1920x1080, the High preset offers the best balance of visual quality and performance, delivering 91.8 FPS, which is well above the 60 FPS threshold for smooth gameplay. The Ultra preset at 1080p yields 68 FPS, which is still playable, but the 26% performance drop from High to Ultra may not justify the visual gains. For competitive play, the Low preset at 164.8 FPS provides maximum responsiveness, though it sacrifices visual fidelity.

At 2560x1440, the Medium preset is the recommended choice, as it produces 74.6 FPS, which is comfortably above 60 FPS. The High preset at 65 FPS is also viable for those prioritizing visual quality over a higher frame rate, while the Low preset at 112 FPS is ideal for fast-paced gameplay. The Ultra preset at 50.4 FPS falls below the 60 FPS threshold and may result in noticeable stuttering, so it is not recommended at this resolution.

At 3840x2160, the Low preset is the only option that maintains a playable frame rate, hitting 66.2 FPS. The Medium preset at 46.4 FPS and High at 37.8 FPS are borderline, while Ultra at 28.3 FPS is unplayable for most users. For 4K gaming, the data suggests that even the Low preset may struggle in dense scenes, as the average FPS is close to the 60 FPS threshold. Users targeting 4K should consider reducing the resolution or investing in a more powerful GPU, as the RTX 4060’s 8 GB VRAM is a limiting factor in Rust’s expansive environments.
