Rust

The AMD Ryzen 9 9900X paired with the NVIDIA GeForce GTX 1660 SUPER produces a specific performance profile in Rust that is heavily constrained by the graphics card. In the database of tested combinations, this pairing ranks 1501 out of 1717 combos, placing it in the lower percentile of systems evaluated. This rank indicates that while the CPU is a high-end component, the overall gaming experience is bottlenecked by the GPU, which pulls the combined score down relative to other pairings. The data shows a system where the processor's potential is largely untapped in this particular title, as the graphics card becomes the primary limiting factor across most settings and resolutions.

How This Combo Ranks

The combo rank of 1501 out of 1717 tested combinations places this system in the lower 13% of all pairings. This is a significant indicator of imbalance, as the AMD Ryzen 9 9900X is a top-tier processor, sitting in the 94th percentile against all CPUs in our benchmark database. Its average benchmark score of 54450 places it just 0.4% behind the AMD Ryzen 9 9900X3D and 0.7% ahead of the Intel Core i7-14700F, showing that the CPU itself is a powerhouse. However, the GPU tells a different story, ranking only in the 55th percentile against all GPUs, with an average benchmark score of 14286. This places it nearly identical to the AMD Radeon RX Vega 11, which is only 0.2% slower, and the Intel Iris Xe MAX Graphics, also 0.2% slower. The data clearly shows that the system's low overall rank is directly attributable to the GPU's modest performance, which holds back the CPU's capabilities in gaming workloads.

GPU Role

The NVIDIA GeForce GTX 1660 SUPER is the decisive component in this pairing. It features 6 GB of GDDR6 memory on a 192-bit bus, providing a memory bandwidth of 336.0 GB/s. Its core clocks run at a base of 1530 MHz and boost up to 1785 MHz. The GPU's raw compute capability is rated at 5.027 TFLOPS for FP32 operations. In the context of Rust, these specifications translate into a hard ceiling for frame rates. The data shows that at 1080p with Low settings, the system achieves an average FPS of 108.2, but this is the absolute peak of its performance envelope. The 6 GB VRAM capacity is a potential concern for a game like Rust, which can be memory-intensive, but the measured results suggest that the GPU's processing power, rather than its memory capacity, is the primary constraint under most tested conditions. The GTX 1660 SUPER's nearest rival, the AMD Radeon RX 5500 XT, is only 0.7% faster in synthetic benchmarks, confirming that this GPU is at the lower end of the discrete graphics spectrum.

Resolution Scaling

The measured FPS data reveals a predictable pattern of performance degradation as resolution increases, which confirms the GPU is the limiting factor. Moving from 1920x1080 to 2560x1440 at High settings, the average FPS drops from 61.5 to 39.2, a 36% reduction. Further scaling to 3840x2160 at High settings yields an average FPS of 25.4, which is a 59% drop from the 1080p result. This scaling behavior is characteristic of a GPU-bound scenario, where the rendering load on the graphics card increases exponentially with pixel count. The CPU's role in this scenario is minimal, as its high core count and clock speeds are not the bottleneck. The data indicates that the GTX 1660 SUPER simply does not have the throughput to maintain playable frame rates at higher resolutions, regardless of the processor's capabilities. The system is only able to provide a smooth experience at 1080p, and even then, only at lower settings.

Measured FPS Breakdown

The complete set of measured average FPS values provides a detailed view of the system's capabilities. At 1920x1080, the performance ranges from a low of 45.7 FPS on Ultra settings to a high of 108.2 FPS on Low settings. The Medium preset achieves 72.4 FPS, while High yields 61.5 FPS. This represents a substantial performance spread of 62.5 FPS between the lowest and highest quality presets. Moving to 2560x1440, the frame rates drop considerably, with Low settings producing 73.3 FPS, Medium producing 46.5 FPS, High producing 39.2 FPS, and Ultra producing 31.2 FPS. At 3840x2160, the system struggles significantly, with Low settings achieving 44.5 FPS, Medium achieving 29.9 FPS, High achieving 25.4 FPS, and Ultra dropping to a nearly unplayable 19.1 FPS. The data shows a clear pattern: the system is only capable of delivering a consistently smooth experience at 1080p, while higher resolutions require significant compromises in visual fidelity to maintain acceptable frame rates.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this pairing depend heavily on the user's target resolution and preference for visual quality versus frame rate. At 1920x1080, the High preset provides a good balance, delivering 61.5 FPS, which is smooth for most gameplay scenarios. The Medium preset offers a more comfortable margin at 72.4 FPS, while the Low preset at 108.2 FPS is ideal for competitive play where maximum frame rate is prioritized. The Ultra preset at 45.7 FPS is playable but may feel less fluid in fast-paced situations. For 2560x1440, the Low preset at 73.3 FPS is the only setting that provides a consistently smooth experience. The Medium preset at 46.5 FPS is borderline, while High and Ultra drop below 40 FPS, which is generally considered the minimum for acceptable playability. At 3840x2160, none of the settings provide a truly smooth experience, with the Low preset at 44.5 FPS being the only viable option, and even that may be too choppy for some users. The data suggests that the best experience is achieved at 1080p with Medium or High settings, offering a good balance of visual quality and performance.

CPU Role

The AMD Ryzen 9 9900X is a 12-core, 24-thread processor based on the Zen 5 architecture, codenamed Granite Ridge, manufactured on a 4 nm process. It has a base clock of 4.40 GHz and a boost clock of 5.60 GHz. This CPU is a top performer, as evidenced by its 94th percentile ranking and an average benchmark score of 54450, which is nearly identical to its nearest rival, the AMD Ryzen 9 9900X3D, which is only 0.4% faster. In Rust, however, the CPU's role is largely secondary. The game's performance is predominantly GPU-limited in this configuration, as the data shows that frame rates scale inversely with resolution and settings, which are GPU-dependent variables. The CPU's high multi-threaded performance, demonstrated by a Cinebench R23 multi-core score of 46438, is more than sufficient to handle the game's simulation and physics workloads. The processor's single-thread performance is also strong, with a Cinebench R23 single-core score of 6555, which is beneficial for games that rely on a few heavily threaded tasks. The data indicates that the CPU is never the limiting factor in this pairing, as the GPU consistently reaches its performance ceiling before the CPU is fully utilized.
