Rust

The Intel Core i7-13700K paired with the NVIDIA GeForce RTX 4090 delivers a dominant performance profile in Rust, placing this combination in the top tier of tested systems. The data shows a setup that is heavily GPU-limited at 4K, but which possesses enough CPU headroom to push exceptional frame rates at lower resolutions. This analysis breaks down the measured performance, focusing on how the resolution and settings interact with this specific hardware pairing.

Resolution Scaling

The frame rate scaling across resolutions reveals a classic transition from a CPU-bound state at 1080p to a GPU-bound state at 4K. At 1080p with Low settings, the combo achieves an average of 253.8 FPS. Moving to 1440p at the same settings drops performance to 221 FPS, a reduction of roughly 13%. However, the most significant bottleneck shift occurs when moving to 4K, where the Low setting average falls to 128.6 FPS. This represents a 42% performance drop from 1440p, indicating that the RTX 4090's rendering workload at 4K is now the primary constraint.

The scaling pattern is even more pronounced at higher graphical presets. At High settings, the transition from 1080p (180.6 FPS) to 1440p (123.2 FPS) is a 32% decrease, while the move from 1440p to 4K (75.8 FPS) is another 38% drop. This consistent ~30-40% decline per resolution step at higher presets confirms that the GPU is the limiting component once the resolution and detail levels increase. At 1080p Ultra, the system still manages 135.6 FPS, showing that even in the most demanding preset, the i7-13700K has ample power to feed the GPU.

The data suggests that for competitive play at 1080p, the CPU is doing the heavy lifting, as evidenced by the relatively small performance gap between Low and Ultra presets at that resolution. The difference between 253.8 FPS (Low) and 135.6 FPS (Ultra) at 1080p is a 47% reduction, which is less severe than the 56% reduction seen at 4K between the same settings. This indicates that at 4K, the GPU's pixel pushing capabilities are the deciding factor, while at 1080p, the system is better balanced.

GPU Role

The NVIDIA GeForce RTX 4090 is the undisputed performance driver in this pairing, particularly at high resolutions. Its 24 GB of GDDR6X memory on a 384-bit bus provides a massive 1.01 TB/s of bandwidth, which is crucial for Rust's large, dynamically generated environments. The data shows that at 4K Ultra, the combo averages 56.3 FPS, which while playable, is the lowest measured result. This is directly attributable to the GPU's workload at that resolution and preset combination.

The GPU's clock behavior, with a base of 2235 MHz and a boost of 2520 MHz, allows it to scale effectively with demand. The benchmark results indicate that the RTX 4090 is performing well above the 91st percentile of all GPUs tested, reinforcing its position as a top-tier component. However, the data also reveals the GPU's end-of-life production status, suggesting that while its performance is still elite, the hardware landscape is evolving.

In Rust specifically, the GPU's role becomes more critical as settings increase. The measured FPS at 1440p Ultra (92.9 FPS) versus 1440p Low (221 FPS) shows a 58% performance penalty for maxing out the visuals. This is a substantial cost, and it highlights that the RTX 4090, despite its immense power, is not immune to the demands of Rust's highest quality presets. The 4K results further cement this, with the Ultra preset delivering only 56.3 FPS, a figure that demands the user consider whether visual fidelity is worth the frame rate sacrifice.

Settings Recommendations

Based on the measured data, the optimal balance of visual quality and performance for this combo is the High preset. At 1080p, High delivers 180.6 FPS, which is 45 FPS below the Low preset but still exceptionally smooth. The jump to Medium at 1080p yields 217 FPS, but High offers a substantial visual improvement over Medium for a relatively modest 36.8 FPS cost. At 1440p, High provides 123.2 FPS, which is an excellent result for a high-refresh-rate monitor.

For 4K gaming, the High preset is the definitive choice. The 75.8 FPS average at 4K High is significantly more fluid than the 56.3 FPS at Ultra, and the visual difference between High and Ultra is often less noticeable in a fast-paced survival game than the frame rate increase. The Low preset at 4K, while achieving 128.6 FPS, sacrifices too much visual fidelity for the hardware available. The Medium preset at 4K (88.9 FPS) is a viable alternative if the user desires a bit more detail than High, but the data suggests that High is the sweet spot for a consistently smooth experience.

The Ultra preset is not recommended for this game and hardware combination. At any resolution, the frame rate cost is too steep. At 1080p, it drops to 135.6 FPS, which is close to the 1440p High result, making it a poor trade-off. At 4K, the 56.3 FPS average is below the threshold for a comfortable experience on many displays. The benchmark data clearly indicates that the High preset offers the best balance of image quality and performance across all tested resolutions.
